ISP Compromised - Everything become failure

My ISP has been compromised. And no idea what to do?  ISP has been already compromised few months back but i thought my router is from local company therefore such issue. But i am wrong. I have use the another router and even firewall. All become waste for me. Firewall fail to stop.  I have send the report to Kaspersky. And kaspersky says the problem from router side. And when i search in google. Some developer says it is from ISP side. I have format my system 3 times, reset router , reset firewall. All become failure.

Routing bug

so we have r80.20 cluster gaia, with fw vpn and ia enabled. corexl and securexl also enabled.couple of days ago i added new vlan on empty interface for point to point against remote site FW, which connected through layer 2 line. so far so good. FWs are having vpn sts with each other. no static routes on that line, only encrypted traffic.this GW actually connect HQ with all branches through main isp line on another interface.today we had downs at least 7 times between HQ and all branches, each down time was for about 10-20 seconds, and go back up by itlsef., after checking with fw monitor i discovered that instead of routing packets directed to branches through the main isp line, the fw routed those packets through the new vlan interface that i meantioned above. and this is why the packets never arrived to the destination.i thought first that maybe i had some duplicate routes, so i have checked, and there is no single route on this vlan interface except of course the directly connected point to point network which is in completely different subnet.the things occured today before it started:they go to this remote site to install pcs and printers etc..  which i don't believe relevant, and i fwaccel off and back on on this GW.in messages i got a lot of :kernel: [fw4_1];fwconn_recover_old_conn: connection is accelerated - cannot set handler.kernel: [fw4_1];fwconn_recover_old_conn: handler (322) VERIFICATION_HANDLER. dropping packetand also a lot from those: kernel: dst_release: dst:ffff8808147852c0 refcnt:-2have no idea what these messages means..it was happening for around 2 hours randomally and stopped about when they left the remote site. which again i don't believe related..to me it looks very like a bug but i'm not sure why it happens just now and why with this new vlan specifically..fwaccel off didn't solve the issue right away, but i just read that in r80.20 it not take effect on all connections as it was before.

R80.XX Jumbo Hotfix Accumulator - Did You Know?

Hi Everyone, My name is @Yifat_Chen   and I’m part of  the Release Operation group managed by @MeravAlon  Our group is responsible for Check Point major releases (e.g R80.20), minor releases (e.g R80.30) and Jumbo Hotfix Accumulator releases for R80.10, R80.20 & R80.30 trains. Following several recent conversations and questions from customers, I would like to provide some general  information regarding the Jumbo Hotfix (JHF) Accumulator: Jumbo Hotfix Accumulator is an accumulation of stability and quality fixes resolving issues in different products. For more information, see sk98028. Check Point  recommends that you install the latest GA Jumbo take on a regular basis. A new Jumbo take is usually released every 1-2 months. For a complete list of fixes in each Jumbo take, please refer to the following SKs: R80.10 JHF SK, R80.10 SmartConsole SK , R80.20 JHF SK , R80.20 SmartConsole SK , R80.30 JHF SK , R80.30 SmartConsole SK Every new Jumbo take has 2 phases: 1st -  Released as “Ongoing” - The main purpose of the “Ongoing” take is early adoption. 2nd – Published as “GA” - Recommended as a General Availability take. After 3-4 weeks, an “Ongoing” take is moved to GA status. If there is a problem with an “Ongoing” take, a new one will be released. A new JHF on the Management Server can be installed regardless of the Gateway server. There’s no requirement to align the Management and Gateway to use the same JHF take. (Note - All Management machines should have the same JHF take.) SmartConsole Jumbo HF is also released every 1-2 months. Note – there is no dependency between SmartConsole and Jumbo takes. Different takes of Jumbo can be used with each SmartConsole take. However – some features/fixes require an upgrade of both Jumbo and SmartConsole. Installing a JHF is not an upgrade process ! The installation of a JHF is simple  and doesn’t perform any changes in the Management Database. JHF  only replaces specific binaries with new fixes, However - a reboot may require after JHF installation  I’m tagging also: @Tsahi_Etziony  – R&D director of Product operation @MeravAlon  - Release Operation Group manager   Please don’t hesitate to contact us for any further questions regarding the Jumbo releases. Regards, Yifat Chen

R80.x Security Gateway Architecture (Logical Packet Flow)

Introduction This document describes the packet flow (partly also connection flows) in a Check Point R80.10 and above with SecureXL and CoreXL, Content Inspection, Stateful inspection, network and port address translation (NAT), MultiCore Virtual Private Network (VPN) functions and forwarding are applied per-packet on the inbound and outbound interfaces of the device. There should be an overview of the basic technologies of a Check Point Firewall. We have also reworked the document several times with Check Point, so that it is now finally available. Chapter More interesting articles:- R80.x Architecture and Performance Tuning - Link Collection- Article list (Heiko Ankenbrand) Flowchart basic What's new in R80.10 and above R80.10 and above offer many technical innovations regarding R77. I will look at the following in this article:- new fw monitor inspection points for VPN (e and E)- new MultiCore VPN- UP Manager- Content Awareness (CTNT) R80.20 and above:- SecureXL has been significantly revised in R80.20. It now works in user space. This has also led to some changes in "fw monitor"- There are new fw monitor chain (SecureXL) objects that do not run in the virtual machine.- Now SecureXL works in user space. The SecureXL driver takes a certain amount of kernel memory per core and that was adding up to more kernel memory than Intel/Linux was allowing.- SecureXL supportes now Async SecureXL with Falcon cards- That's new in acceleration high level architecture (SecureXL on Acceleration Card): Streaming over SecureXL, Lite Parsers, Scalable SecureXL, Acceleration stickiness- Policy push acceleration on Falcon cards- Falcon cards for: Low Latency, High Connections Rate, SSL Boost, Deep Inspection Acceleration, Modular Connectivity, Multible Acceleration modules- Falcon card compatible with 5900, 15000 & 23000 Appliance Series > 1G (8x1 GbE), 10G (4x10 GbE) and 40G (2x40 GbE) R80.30 and above:- In R80.30+, you can also allocate a core for management traffic if you have 8 or more cores licensed, but this is not the default.- Active streaming for https with full SNI support. R80.40 and above:- Support for automatic allocation of CoreXL SNDs and Firewall instances that does not require a Security Gateway reboot.- CoreXL and Multi-Queue: Improved out of the box experience - Security Gateway automatically changes the number of CoreXL SNDs and Firewall instances and the Multi-Queue configuration based on the current traffic load.- Check Point's Security Gateway now support HTTP/2- A new Policy Layer in SmartConsole dedicated to TLS Inspection and different TLS Inspection layers can be used in different policy packages.- Enhanced NAT port allocation mechanism - on Security Gateways with 6 or more CoreXL Firewall instances, all instances use the same pool of NAT ports, which optimizes the port utilization and reuse.- Multiple CoreXL Firewall instances handle the SIP protocol to enhance performance.- Cluster Control Protocol encryption is now enabled by default. Flowchart (new in R80.20+) SecureXL has been significantly revised in R80.20. This has also led to some changes in "fw monitor". There are new fw monitor chain (SecureXL) objects that do not run in the virtual machine. Now SecureXL works in part in user space. The SecureXL driver takes a certain amount of kernel memory per core and that was adding up to more kernel memory than Intel/Linux was allowing. The packet flow in R80.20+ is a little bit different from the flow lower than R80.20. Now it is possible to use async SecureXL and other new functions. This figure shows the new features with the reinjection of SecureXL packages. SecureXL supportes now also Async SecureXL with Falcon cards. That's new in acceleration high level architecture (SecureXL on Acceleration Card): Streaming over SecureXL, Lite Parsers, Scalable SecureXL, Acceleration stickiness. Whats new in R80.20/R80.30+: Now there are several SecureXL instances possible. As a result, there are now eight pathes instead of three. (I will make a drawing with the new paths in the next weeks): Slow path (F2F) Medium path (PSLXL or old name PXL) Acceleration path (SXL) New in R80.20/R80.30:  F2W path New in R80.20/R80.30:  Correction path (packet reinjection see picture) New in R80.20/R80.30:  Host path (only on Falcon cards) New in R80.20/R80.30:  Buffer path (only on Falcon cards) New in R80.20/R80.30:  Inline path (only on Falcon cards) Note: F2V - Describes VPN Connections via the F2F path. As a result, packets are reinjected with the new SecureXL ID into the correct SecureXL instance again after they have been allowed by access template or rule set. After the packet has been reinjected, the SecureXL ID is added to the SecureXL connetion table and the packet is forwarded to the correct SecureXL instance. Therefore the flow is slightly different to older version before R80.20. This new mechanism also offers the possibility to transfer packets into a new SecureXL instance on Falcon cards. PXL vs. PSLXL - Technology name for combination of SecureXL and PSL. PXL was renamed to PSLXL in R80.20. This is from my point of view the politically correct better term. R80.20 / R80.30 and above: R80.20 SecureXL adds support for offloading on Falcon cards from appliance to acceleration card leaving the appliance to do more. The following flowchart shows the new R80.20/r80.30 offloaded architecture in pink. Host Path - For non acceleration connections (eg. local connections) and connections on non acceleration card interface.     Buffer path - For HTTP requests, HTTP response headers and TLS handshakes.     Inline path - For HTTP response body (until 1st tier match) and TLS bulk encryption/ decryption.   For the new acceleration Falcon card architecture with R80.20+ and SecureXL offloading read this article:R80.x Security Gateway Architecture (Acceleration Card Offloading): VPN Decrypting a packet: R80.10 and R80.20 introduced MultiCore support (it is new in R80 and above) for IPsec VPN. An IPSec packet enters the Security Gateway. The decrypted original packet is forwarded to the connection CoreXL FW instance for FireWall inspection at Pre-Inbound chain "i" from SND. The decrypted inspected packet is sent to the OS Kernel. Encrypting a packet: Encryption information is prepared at Post-Outbound chain "O". The vpnk module on the tunnel CoreXL FW instance gets the packet before encryption at chain "e". The encryption packet is forwarded to the connection CoreXL FW instance for FireWall from SND. The packet is encrypted by vpnk module at chain "E". Afterwards the IPsec packet is sent out on interface. This fw monitor inspection points "e" and "E" are new in R80.10 and "oe" and "OE" are new in R80.20. Note: It's true, they only exist on the outbound side for encrypting packets not for decrypting packets on inbound side. Note: F2V - Describes VPN Connections via the F2F path. R80.20 VPN+SecureXL and above: (SK151114) Disabling acceleration by running fwaccel off will not have an immediate effect on IPsec acceleration, as it did before R80.20. Using fwaccel off, will cause every existing VPN connection to continue to be processed by the acceleration module (SecureXL), and only new connections will not be offloaded to the acceleration module. As long as there are accelerated VPN connections associated with the IPsec tunnel, all decryption/encryption operations will continue to be handled by the acceleration module. VPN before R80.20, VPN connections could be migrated between acceleration module and Firewall-1 instances due to synchronous communication between those modules. VPN since R80.20, fwaccel off does not stop the SecureXL device, and the communication between SecureXL and firewall-1 is now asynchronous. All connections that were accelerated will continue to be handled by PPAK. Furthermore, when new decryption/encryption keys are generated, the decision whether to accelerate the tunnel or not depends on whether there are accelerated connections associated with the tunnel. As a result, to disable VPN tunnel acceleration all outstanding related connections should be terminated. This behavior prevents disabling acceleration of tunnels as long as accelerated connections are associated with those tunnels. Firewall Core Inbound Stateless Check: The firewall does preliminary “stateless” checks that do not require context in order to decide whether to accept a packet or not. For instance we check that the packet is a valid packet and if the header is compliant with RFC standards. Anti-Spoofing: Anti-Spoofing verifies that the source IP of each packet matches the interface, on which it was encountered. On internal interfaces we only allow packets whose source IP is within the user-defined network topology. On the external interface we allow all source IPs except for ones that belong to internal networks. Connection Setup: A core component of the Check Point R80.x Threat Prevention gateway is the stateful inspection firewall. A stateful firewall tracks the state of network connections in memory to identify other packets belonging to the same connection and to dynamically open connections that belong to the same session. Allowing FTP data connections using the information in the control connection is one such example. Using Check Point INSPECT code the firewall is able to dynamically recognize that the FTP control connection is opening a separate data connection to transfer data. When the client requests that the server generate the back-connection (an FTP PORT command), INSPECT code extracts the port number from the request. Both client and server IP addresses and both port numbers are recorded in an FTP-data pending request list. When the FTP data connection is attempted, the firewall examines the list and verifies that the attempt is in response to a valid request. The list of connections is maintained dynamically, so that only the required FTP ports are opened. SecureXL SecureXL is a software acceleration product installed on Security Gateways. Performance Pack uses SecureXL technology and other innovative network acceleration techniques to deliver wire-speed performance for Security Gateways. SecureXL is implemented either in software or in hardware:       SAM cards on Check Point 21000 appliances       ADP cards on IP Series appliances       Falcon cards (new in R80.20) on different appliances The SecureXL device minimizes the connections that are processed by the INSPECT driver. SecureXL accelerates connections on two ways. New in R80.10: In R80.10 SecureXL adds support for Domain Objects, Dynamic Objects and Time Objects. CoreXL accelerates VPN traffic by distributing Next Generation Threat Prevention inspection across multiple cores.   New in R80.20: SecureXL was significantly revised in R80.20. It no longer works in Linux kernel mode but now in user space. In kernel mode  resources (for example memory) are very limited. This has the advantage that more resources can be used in user space. The SecureXL driver takes a certain amount of kernel memory per core and that was adding up to more kernel memory than Intel/Linux was allowing. On the 23900 in particular, we could not leverage all the processor cores due to this limitation. By moving all or most of SecureXL to user space, it's possible to leverage more processor cores as the firewall can entirely run in user space.It still doesn't by default in R80.20 in non-VSX mode, but it can be enabled.  It also means certain kinds of low-level packet processing that could not easily be done in SecureXL because it was being done in the kernel now can. For VSX in particular, it means you can now configure the penalty box features on a per-VS basis. It also improves session establishment rates on the higher-end appliances. In addition, the following functions have been integrated in R80.20 SecureXL:         SecureXL on Acceleration Cards (AC)         Streaming over SecureXL         Lite Parsers         Async SecureXL         Scalable SecureXL         Acceleration stickiness         Policy push acceleration Throughput Acceleration - The first packets of a new TCP connection require more processing when processed by the firewall module. If the connection is eligible for acceleration, after minimal security processing the packet is offloaded to the SecureXL device associated with the proper egress interface. Subsequent packets of the connection can be processed on the accelerated path and directly sent from the inbound to the outbound interface via the SecureXL device. Connection Rate Acceleration  SecureXL also improves the rate of new connections (connections per second) and the connection setup/teardown rate (sessions per second). To accelerate the rate of new connections, connections that do not match a specified 5 tuple are still processed by SecureXL. For example, if the source port is masked and only the other 4 tuple attributes require a match. When a connection is processed on the accelerated path, SecureXL creates a template of that connection that does not include the source port tuple. A new connection that matches the other 4 tuples is processed on the accelerated path because it matches the template. The firewall module does not inspect the new connection, increasing firewall connection rates.SecureXL and the firewall module keep their own state tables and communicate updates to each other. Connection notification - SecureXL passes the relevant information about accelerated connections that match an accept template. Connection offload - Firewall kernel passes the relevant information about the connection from firewall connections table to SecureXL connections table. In addition to accept templates the SecureXL device is also able to apply drop templates which are derived from security rules where the action is drop. In addition to firewall security policy enforcement, SecureXL also accelerates NAT, and IPsec VPN traffic. QXL - Technology name for combination of SecureXL and QoS (R77.10 and above).This has no direct association with PXL. It is used exclusively for QoS. But also here it is possible to use the QoS path in combination with PSL. SAM card  and Falcon card (R80.20 and above) - Security Acceleration Module card. Connections that use SAM/Falcon card, are accelerated by SecureXL and are processed by the SAM/Falcon card's CPU instead of the main CPU (refer to 21000 Appliance Security Acceleration Module Getting Started Guide)). SecureXL use the following templates: If templating is used under SecureXL, the templates are created when the firewall ruleset is installed. Accept Template - Feature that accelerates the speed, at which a connection is established by matching a new connection to a set of attributes. When a new connection matches the Accept Template, subsequent connections are established without performing a rule match and therefore are accelerated. Accept Templates are generated from active connections according to policy rules. Currently, Accept Template acceleration is performed only on connections with the same destination port (using wildcards for source ports). Accept Tamplate is enabled by default if SecureXL is used. Drop Template - Feature that accelerates the speed, at which a connection is dropped by matching a new connection to a set of attributes. When a new connection matches the Drop Template, subsequent connections are dropped without performing a rule match and therefore are accelerated. Currently, Drop Template acceleration is performed only on connections with the same destination port (does not use wildcards for source ports).Drop Template is disabled by default if SecureXL is used. It can be activated via smart Dashboard and does not require a reboot of the firewall. NAT Templates - Using SecureXL Templates for NAT traffic is critical to achieve high session rate for NAT. SecureXL Templates are supported for Static NAT and Hide NAT using the existing SecureXL Templates mechanism. Normally the first packet would use the F2F path. However, if SecureXL is used, the first packet will not be forwarded to the F2F path if Accept Tamplate and NAT Template match. Enabling or disabling of NAT Templates requires a firewall reboot. R80.10 and lower:  NAT Template is disabled by default. R80.20 and above: NAT Template is enabled by design. SecureXL path: Fast path (Accelerated Path) - Packet flow when the packet is completely handled by the SecureXL device. It is processed and forwarded to the network.Note: In many discusions and images, the SXL path is marked with the "accelerated path". This also happened to me by mistake in this flowchart. Medium path (PXL) - The CoreXL layer passes the packet to one of the CoreXL FW instances to perform the processing (even when CoreXL is disabled, the CoreXL infrastructure is used by SecureXL device to send the packet to the single FW instance that still functions). When Medium Path is available, TCP handshake is fully accelerated with SecureXL. Rulebase match is achieved for the first packet through an existing connection acceleration template. SYN-ACK and ACK packets are also fully accelerated. However, once data starts flowing, to stream it for Content Inspection, the packets will be now handled by a FWK instance. Any packets containing data will be sent to FWK for data extraction to build the data stream. RST, FIN and FIN-ACK packets once again are only handled by SecureXL as they do not contain any data that needs to be streamed. This path is available only when CoreXL is enabled. Packet flow when the packet is handled by the SecureXL device, except for: IPS (some protections) VPN (in some configurations) Application Control Content Awareness Anti-Virus Anti-Bot HTTPS Inspection Proxy mode Mobile Access VoIP Web Portals. PXL vs. PSLXL - Technology name for combination of SecureXL and PSL. PXL was renamed to PSLXL in R80.20. This is from my point of view the politically correct better term. Medium path (CPASXL) - Now also CPAS use the SecureXL path in R80.20. CPAS works through the F2F path in R80.10 and R77.30. Now CPASXL is offered in SecureXL path in R80.20. This should lead to a higher performance. Check Point Active Streaming active streaming allow the changing of data and play the role of “man in the middle”. Several protocols uses CPAS, for example: Client Authentication, VoIP (SIP, Skinny/SCCP, H.323, etc.), Data Leak Prevention (DLP) blade, Security Servers processes, etc. I think it's not to be underestimated in tuning. Slow path  or Firewall path (F2F) - Packet flow when the SecureXL device is unable to process the packet. The packet is passed on to the CoreXL layer and then to one of the Core FW instances for full processing. This path also processes all packets when SecureXL is disabled. New in R80.20: Inline Streaming path, Medium Streaming path,  Host path and Buffer path - Are new SecureXL paths used in conjunction with Falcon cards. They are described in more detail in the following article "R80.x Security Gateway Architecture (Acceleration Card Offloading) ". Note to Falcon Cards: Theoretically and practically there are even more than these three paths. This has to do with the offloading of SAM and Falcon cards (new in R80.20)  and with QXL (Quality of Service) and other SecureXL technologies. It's beyond the scope of this one. Fast Accelerator - The Fast Acceleration feature (green) lets you define trusted connections to allow bypassing deep packet inspection on R80.20 JHF103 and above gateways. This feature significantly improves throughput for these trusted high volume connections and reduces CPU consumption. The CLI of the gateway can be used to create rules that allow you to bypass the SecureXL PSLXL path to route all connections through the fast path.  SecureXL chain modules (new in R80.20 and above) SecureXL has been significantly revised in R80.20. It now works in user space. This has also led to some changes in "fw monitor" There are new fw monitor chain (SecureXL) objects that do not run in the virtual machine. The new fw monitor chain modules (SecureXL) do not run in the virtual machine (vm). SecureXL inbound (sxl_in)                 > Packet received in SecureXL from networkSecureXL inbound CT (sxl_ct)           > Accelerated packets moved from inbound to outbound processing (post routing)SecureXL outbound (sxl_out)            > Accelerated packet starts outbound processingSecureXL deliver (sxl_deliver)          > SecureXL transmits accelerated packet There are more new chain modules in R80.20 vpn before offload (vpn_in)                > FW inbound preparing the tunnel for offloading the packet (along with the connection)fw offload inbound (offload_in)           > FW inbound that perform the offload fw post VM inbound  (post_vm)          > Packet was not offloaded (slow path) - continue processing in FW inbound CoreXL CoreXL is a performance-enhancing technology for Security Gateways on multi-CPU-core processing platforms. CoreXL enhances Security Gateway performance by enabling the processing CPU cores to concurrently perform multiple tasks. CoreXL provides almost linear scalability of performance, according to the number of processing CPU cores on a single machine. The increase in performance is achieved without requiring any changes to management or to network topology. On a Security Gateway with CoreXL enabled, the Firewall kernel is replicated multiple times. Each replicated copy, or FW instance, runs on one processing CPU core. These FW instances handle traffic concurrently, and each FW instance is a complete and independent FW inspection kernel. When CoreXL is enabled, all the FW kernel instances in the Security Gateway process traffic through the same interfaces and apply the same security policy. R80.20 CoreXL does not support these Check Point features: Overlapping NAT, VPN Traditional Mode,  6in4 traffic - this traffic is always processed by the global CoreXL FW instance #0 (fw_worker_0) and more (see CoreXL Known Limitations). Secure Network Distributor (SND) - Traffic entering network interface cards (NICs) is directed to a processing CPU core running the SND, which is responsible for:        Processing incoming traffic from the network interfaces        Securely accelerating authorized packets (if SecureXL is enabled)        Distributing non-accelerated packets among Firewall kernel instances (SND maintains global dispatching table - which connection was assigned to which instance) SND does not really touch any packet. The decision to stick to a particular FWK core is done at the first packet of connection on a very high level before anything else. Depending on SXL settings and in most of the cases, SXL can be offloading decryption calculations. However, in some other cases, such as with Route-Based VPN, it is done by FWK. Firewall Instance (fw_worker) - On a Security Gateway with CoreXL enabled, the Firewall kernel is replicated multiple times. Each replicated copy, or Firewall Instance, runs on one CPU processing core. These FW instances handle traffic concurrently, and each FW instance is a complete and independent Firewall inspection kernel. When CoreXL is enabled, all the Firewall kernel instances on the Security Gateway process traffic through the same interfaces and apply the same security policy. Dynamic Dispatcher - Rather than statically assigning new connections to a CoreXL FW instance based on packet's IP addresses and IP protocol (static hash function), the new dynamic assignment mechanism is based on the utilization of CPU cores, on which the CoreXL FW instances are running. The dynamic decision is made for first packets of connections, by assigning each of the CoreXL FW instances a rank, and selecting the CoreXL FW instance with the lowest rank. The rank for each CoreXL FW instance is calculated according to its CPU utilization. The higher the CPU utilization, the higher the CoreXL FW instance's rank is, hence this CoreXL FW instance is less likely to be selected by the CoreXL SND. The CoreXL Dynamic Dispatcher allows for better load distribution and helps mitigate connectivity issues during traffic "peaks", as connections opened at a high rate that would have been assigned to the same CoreXL FW instance by a static decision, will now be distributed to several CoreXL FW instances. Multi Queue - Network interfaces on a security gateway typically receive traffic at different throughputs; some are busier than others. At a low level, when a packet is received from the NIC, then a CPU core must be “interrupted” to the exclusion of all other processes, in order to receive the packet for processing. To avoid bottlenecks we allow multiple buffers, and therefore CPU cores, to be affined to an interface. Each affined buffer can “interrupt” its own CPU core allowing high volumes of inbound packets to be shared across multiple dispatchers. When most of the traffic is accelerated by the SecureXL, the CPU load from the CoreXLSND instances can be very high, while the CPU load from the CoreXL FW instances can be very low. This is an inefficient utilization of CPU capacity. By default, the number of CPU cores allocated to CoreXL SND instances is limited by the number of network interfaces that handle the traffic. Because each interface has one traffic queue, only one CPU core can handle each traffic queue at a time. This means that each CoreXL SND instance can use only one CPU core at a time for each network interface. Check Point Multi-Queue lets you configure more than one traffic queue for each network interface. For each interface, you can use more than one CPU core (that runs CoreXL SND) for traffic acceleration. This balances the load efficiently between the CPU cores that run the CoreXL SND instances and the CPU cores that run CoreXL FW instances.   Priority Queues -  In some situations a security gateway can be overwhelmed; in circumstances where traffic levels exceed the capabilities of the hardware, either legitimate traffic or from a DOS attack, it is vital that we can maintain management communications and continue to interact with dynamic routing neighbors. The Priority Queues functionality prioritizes control connections over data connections based on priority.   Affinity - Association of a particular network interface / FW kernel instance / daemon with a CPU core (either 'Automatic' (default), or 'Manual'). The default CoreXL interface affinity setting for all interfaces is 'Automatic' when SecureXL is installed and enabled. If SecureXL is enabled - the default affinities of all interfaces are 'Automatic' - the affinity for each interface is automatically reset every 60 seconds, and balanced between available CPU cores based on the current load. If SecureXL is disabled - the default affinities of all interfaces are with available CPU cores - those CPU cores that are not running a CoreXL FW instance or not defined as the affinity for a daemon. The association of a particular interface with a specific processing CPU core is called the interface's affinity with that CPU core. This affinity causes the interface's traffic to be directed to that CPU core and the CoreXL SND to run on that CPU core. The association of a particular CoreXL FW instance with a specific CPU core is called the CoreXL FW instance's affinity with that CPU core. The association of a particular user space process with a specific CPU core is called the process's affinity with that CPU core. The default affinity setting for all interfaces is Automatic. Automatic affinity means that if SecureXL is enabled, the affinity for each interface is reset periodically and balanced between the available CPU cores. If SecureXL is disabled, the default affinities of all interfaces are with one available CPU core. In both cases, all processing CPU cores that run a CoreXL FW instance, or defined as the affinity for another user space process, is considered unavailable, and the affinity for interfaces is not set to those CPU cores. The default affinity setting for all interfaces is Automatic. Automatic affinity means that if SecureXL is enabled, the affinity for each interface is reset periodically and balanced between the available CPU cores. If SecureXL is disabled, the default affinities of all interfaces are with one available CPU core. In both cases, all processing CPU cores that run a CoreXL FW instance, or defined as the affinity for another user space process, is considered unavailable, and the affinity for interfaces is not set to those CPU cores. Passive Streaming Library (PSL) - IPS infrastructure, which transparently listens to TCP traffic as network packets, and rebuilds the TCP stream out of these packets. Passive Streaming can listen to all TCP traffic, but process only the data packets, which belong to a previously registered connection. PXL - Technology name for combination of SecureXL and PSL. The maximal number of possible CoreXL IPv4 FW instances: Version Check Point Appliance Open Server R80.10 (Gaia 32-bit) 16 16 R80.10 (Gaia 64-bit) 40 40 R77.30 (Gaia 32-bit) 16 16 R77.30 (Gaia 64-bit) 32 32 USFW - In kernel-mode FW, the maximum number of running cores is limited to 40 because of the Linux/Intel limitation of 2GB kernel memory, and because CoreXL architecture needs to load a large driver (~40MB) dozens of times (according to the CPU number, and up to 40 times). Newer platforms that contain more than 40 cores (e.g., 23900) are not fully utilized. Now it is possible to use more then 40 CoreXL cores in R80.10+ user mode firewall. For more informations see sk149973, Management Core - New in R80.30+, you can also allocate a core for management traffic if you have 8 or more cores licensed, but this is not the default. R80.30+ feature for separating management from data traffic via Routing Separation and Resource Separation as described in sk138672. R80.40+ (automatically changes CoreXL, SNDˋs and the Multi-Queue) New in R80.40+Support for automatic allocation of CoreXL SNDs and Firewall instances that does not require a Security Gateway reboot.CoreXL and Multi-Queue: Improved out of the box experience - Security Gateway automatically changes the number of CoreXL SNDs and Firewall instances and the Multi-Queue configuration based on the current traffic load. Changing CoreXL split between FW workers and SND on the fly based on CPU utilization Deciding keys:The average utilization of CoreXL SNDs and FWs are regularly sampled. If either CoreXL SNDs or FWs utilization is higher than the other, perform an estimate of utilization post “migrating” a CPU to the other group.  Note when SMT is on, change is doubled. Supported on OS 3.10 (USFW/Kernel). Check Point appliances with 8 cores or more and VSX is currently a limitation. Supported on Cluster HA and VSLS is currently a limitation. Flows:If more SNDs are needed: Find least utilized CoreXL FW instance Stop dispatching new connections to the least utilized CoreXL FW instance Move the CoreXL FW instance to the CPU of next least utilized CoreXL FW instance Turn on a new MQ queue on the “evicted” CPUNote: Eligible CoreXL SNDs must have a MQ queue ready If more FWs (CoreXL) are needed: Choose the last “stopped” CoreXL FW instance Turn off MQ queue from the CPU it originally occupied Move the chosen CoreXL FW instance to the original CPU it occupied Start dispatching new connections to that CoreXL FW instanceNote: No more than the maximum number of FWs can be added FW Monitor Inspection Points  There are new fw monitor inspection points (red) when a packet passes through a R80.20+ Security Gateway: Inspection point Name of fw monitor inspection point Relation to firewall VM Available since version i Pre-Inbound Before the inbound FireWall VM                            (for example, eth1:i) always I Post-Inbound After the inbound FireWall VM                               (for example, eth1:I) always id Pre-Inbound VPN Inbound before decrypt                                          (for example, eth1:id) R80.20 ID Post-Inbound VPN Inbound after decrypt                                             (for example, eth1:ID) R80.20 iq Pre-Inbound QoS Inbound before QoS                                               (for example, eth1:iq) R80.20 IQ Post-Inbound QoS Inbound after QoS                                                  (for example, eth1:IQ) R80.20 o Pre-Outbound Before the outbound FireWall VM                           (for example, eth1:o) always O Post-Outbound After the outbound FireWall VM                              (for example, eth1:O) always e oe Pre-Outbound VPN Outbound before encrypt                                        (for example, eth1:e)    in R80.10                                                                                 (for example, eth1:oe)  in R80.20 R80.10 R80.20 E OE Post-Outbound VPN Outbound after encrypt                                           (for example, eth1:E)    in R80.10                                                                                 (for example, eth1:OE)  in R80.20 R80.10 R80.20 oq Pre-Outbound QoS Outbound before QoS                                             (for example, eth1:oq) R80.20 OQ Post-Outbound QoS Outbound after QoS                                                (for example, eth1:OQ) R80.20   The "Pre-Encrypt" fw monitor inspection point (e) and the "Post-Encrypt" fw monitor inspection point (E) are new in R80 and above. Note: It's true, they only exist on the outbound side for encrypting packets not for decrypting packets on inbound side. New in R80.20+: In Firewall kernel (now also SecureXL), each kernel is associated with a key witch specifies the type of traffic applicable to the chain modul. # fw ctl chain Key Function ffffffff IP Option Stip/Restore 00000001 new processed flows 00000002 wire mode 00000003 will applied to all ciphered traffic (VPN) 00000000 SecureXL offloading (new in R80.20+)   Content Inspection For more details see article: R80.x Security Gateway Architecture (Content Inspection)  Content inspection is a very complicated process, it is only shown in the example for R80.10 IPS and R80.10 App Classifier. It is also possible for other services. Please refer to the corresponding SK's. In principle, all content is processed via the Context Management Infrastructure (CMI) and CMI loader and forwarded to the corresponding daemon. Session-based processing enforces advanced access control and threat detection and prevention capabilities. To do this we assemble packets into a stream, parse the stream for relevant contexts and then security modules inspect the content. When possible, a common pattern matcher does simultaneous inspection of the content for multiple security modules. In multi-core systems this processing is distributed amongst the cores to provide near linear scalability on each additional core.   Security modules use a local cache to detect known threats. This local cache is backed up with real-time lookups of an  cloud service. The result of cloud lookups are then cached in the kernel for subsequent lookups. Cloud assist also enhances unknown threat detection and prevention. In particular a file whose signature is not known in a local cache is sent to our cloud service for processing where compute, disk and memory are virtually unlimited. Our sandboxing technology, SandBlast Threat Emulation, identifies threats in their infancy before malware has an opportunity to deploy and evade detection. Newly discovered threats are sent to the cloud database to protect other Check Point connected gateways and devices. When possible, active content is removed from files which are then sent on to the user while the emulation is done. Passive Streaming Library (PSL) -Packets may arrive out of order or may be legitimate retransmissions of packets that have not yet received an acknowledgment. In some cases a retransmission may also be a deliberate attempt to evade IPS detection by sending the malicious payload in the retransmission. Security Gateway ensures that only valid packets are allowed to proceed to destinations. It does this with Passive Streaming Library (PSL) technology. PSL is an infrastructure layer, which provides stream reassembly for TCP connections. The gateway makes sure that TCP data seen by the destination system is the same as seen by code above PSL.This layer handles packet reordering, congestion handling and is responsible for various security aspects of the TCP layer such as handling payload overlaps, some DoS attacks and others. The PSL layer is capable of receiving packets from the firewall chain and from SecureXL module. The PSL layer serves as a middleman between the various security applications and the network packets. It provides the applications with a coherent stream of data to work with, free of various network problems or attacks The PSL infrastructure is wrapped with well defined APIs called the Unified Streaming APIs which are used by the applications to register and access streamed data. Protocol Parsers - The Protocol Parsers main functions are to ensure compliance to well-defined protocol standards, detect anomalies if any exist, and assemble the data for further inspection by other components of the IPS engine. They include HTTP, SMTP, DNS, IMAP, Citrix, and many others. In a way, protocol parsers are the heart of the IPS system. They register themselves with the streaming engine (usually PSL), get the streamed data, and dissect the protocol.The protocol parsers can analyze the protocols on both Client to Server (C2S) and Server to Client (S2C) directions. The outcome of the protocol parsers are contexts. A context is a well defined part of the protocol, on which further security analysis can be made. Examples of such contexts are HTTP URL, FTP command, FTP file name, HTTP response, and certain files. Context Management Infrastructure (CMI) and Protections - The Context Management Infrastructure (CMI) is the "brain" of the content inspection. It coordinates different components, decides which protections should run on a certain packet, decides the final action to be performed on the packet and issues an event log.CMI separates parsers and protections. Protection is a set of signatures or/and handlers, where Signature - a malicious pattern that is searched for Handler - INSPECT code that performs more complex inspection CMI is a way to connect and manage parsers and protections. Since they are separated, protections can be added in updates, while performance does not depend on the number of active protections. Protections are usually written per protocol contexts - they get the data from the contexts and validate it against relevant signatures Based on the IPS policy, the CMI determines which protections should be activated on every context discovered by a protocol parser. If policy dictates that no protections should run, then the relevant parsers on this traffic are bypassed in order to improve performance and reduce potential false positives. When a protection is activated, it can decide whether the given packet or context is OK or not. It does not decide what to do with this packet. The CMI is responsible for the final action to be performed on the packet, given several considerations. The considerations include: Activation status of the protection (Prevent, Detect, Inactive) Exceptions either on traffic or on protection Bypass mode status (the software fail open capability) Troubleshooting mode status Are we protecting the internal network only or all traffic CMI Loader - collects signatures from multiple sources (e.g. IPS, Application Control,...) and compiles them together into unified Pattern Matchers (PM) (one for each context - such as URL, Host header etc.). Pattern Matcher -The Pattern Matcher is a fundamental engine within the new enforcement architecture. Pattern Matcher quickly identifies harmless packets, common signatures inmalicious packets, and does a second level analysis to reduce false positives. Pattern Matcher engine provides the ability to find regular expressions on a stream of data using a two tiered inspection process. UP Manager - The UP Manager controls all interactions of the components and interfaces with the Context Management Infrastructure (CMI) Loader, the traffic director of the CMI. The UP Manager also has a list of Classifiers that have registered for “first packets” and uses a bitmap to instruct the UP Classifier to execute these Classifier Apps to run on the packet. The “first packets” arrive directly from the CMI. Parsing of the protocol and streaming are not needed in this stage of the connection. For “first packets” the UP Manager executes the rule base.   Classifier - When the “first packet” rule base check is complete Classifiers initiate streaming for subsequent packets in the session. The “first packet” rule base check identifies a list of rules that possibly may match and a list of classifier objects (CLOBs) that are required to complete the rule base matching process. The Classifier reads this list and generates the required CLOBs to complete the rule base matching. Each Classifier App executes on the packet and tells the result of the CLOB to the UP Manager. The CMI then tells the Protocol Parser to enable streaming. In some cases Classifier Apps do not require streaming, e.g. the first packet information is sufficient. Then the rule base decision can be done on the first packet.       Dynamic Objects       Domain Objects       Only the firewall is enabled On subsequent packets the Classifier can be contacted directly from the CMI using the CMI Loader infrastructure, e.g. when the Pattern Matcher has found a match it informs the CMI it has found application xyz. The CMI Loader passes this information to the Classifier. The Classifier runs the Classification Apps to generate CLOBs required for Application Control and sends the CLOBs to the Observer.   Observer - The Observer decides if enough information is known to publish a CLOB to the security policy. CLOBs are observed in the context of their transaction and the connection that the transaction belongs to. The Observer may request more CLOBs for a dedicated packet from the Classifier or decides that it has sufficient information about the packet to execute the rule base on the CLOB, e.g. if a file type is needed for Content Awareness and the gateway hasn’t yet received the S2C response containing the file. Executing the rule base on a CLOB is called “publishing a CLOB”. The Observer may wait to receive more CLOBs that belong to the same transaction before publishing the CLOBs.   Security Policy - The Security Policy receives the CLOB published by the Observer. The CLOB includes a description of the Blade it belongs to so that matching can be performed on a column basis. The security policy saves the current state on the transaction Handle; either to continue the inspection or final match. The first packets are received directly from the UP Manager. Subsequent packets are received by the rule base from the Observer. Handle - Each connection may consist of several transactions. Each transaction has a Handle. Each Handle contains a list of published CLOBs. The Handle holds the state of the security policy matching process. The Handle infrastructure component stores the rule base matching state related information.   Subsequent Packets - Subsequent packets are handled by the streaming engine. The streaming engine notifies the Classifier to perform the classification. The Classifier will notify the UP Manager about the performed classification and pass the CLOBs to the Observer. The CLOBs will then be received by the Observer that will need to wait for information from the CMI. The CMI sends the information describing the result of the Protocol Parser and the Pattern Matcher to the Classifier. The Classifier informs the UP Manager and sends the CLOB to the Observer. The UP Manager then instructs the Observer to publish the CLOBs to the Rule Base. The Rule Base is executed on the CLOBs and the result is communicated to the UP Manager. The CLOBs and related Rule Base state are stored in the Handle. The UP Manager provides the result of the rule base check to the CMI that then decides to allow or to drop the connection. The CMI generates a log message and instructs the streaming engine to forward the packets to the outbound interface. Content Awareness (CTNT) -  is a new blade introduced in R80.10 as part of the new Unified Access Control Policy. Using Content Awareness blade as part of Firewall policy allows the administrator to enforce the Security Policy based on the content of the traffic by identifying files and its content. Content Awareness restricts the Data Types that users can upload or download.Content Awareness can be used together with Application Control to enforce more interesting scenarios (e.g. identify which files are uploaded to DropBox).

This is only possible to a limited extent, as these are different technologies. It's really an impossible mission. Why!- CoreXL is a mechanism to assign, balance and manage CPU cores. CoreXL SND makes a decision to "stick" particular connection going through to a specific FWK instance.- SecureXL certain connections could avoid FW path partially (packet acceleration) or completely (acceleration with templates) Q: Why both technologies in one flowchart?A: There are both technologies that play hand in hand. The two illustrations become problematic, e.g. in the Medium Path. Q: Why in the Medium Path?A: Here, the packet-oriented part (SecureXL) cannot be mapped with the connection-based part (CoreXL). Therefore, the following note from an new Check Point article from Valeri Loukine   (Security Gateway Packet Flow and Acceleration - with Diagrams - 08-07-2018) and original article from Moti Sagey (Check Point Threat Prevention Packet Flow and Architecture - 04-25-2017) :When Medium Path is available, TCP handshake is fully accelerated with SecureXL. Rulebase match is achieved for the first packet through an existing connection acceleration template. SYN-ACK and ACK packets are also fully accelerated. However, once data starts flowing, to stream it for Content Inspection, the packets will be now handled by a FWK instance. Any packets containing data will be sent to FWK for data extraction to build the data stream. RST, FIN and FIN-ACK packets once again are only handled by SecureXL as they do not contain any data that needs to be streamed. Q: What is the point of this article?A: To create an overview of both worlds with regard to the following innovations in R80.x:- new fw monitor inspection points in R80 (e and E)- new MultiCore VPN with dispatcher- new UP Manager in R80 Q: Why is there the designation "Logical Packet Flow"? A: Since the logical flow in the overview differs from the real flow. For example, the medium path is only a single-logical representation of the real path. This was necessary to map all three paths (F2F, SXL, PXL) in one image. That is why the name "Logical Packet Flow". Q: What's the next step? A: I'm thinking about how to make the overview even better. Q: Wording? A: It was important for me that the right terms from Check Point were used. Many documents on the Internet use the terms incorrectly. Therefore I am grateful to everyone who still finds wording errors here. Q: What's the GA version? A: This version has approved by Check Point representative, and we agreed that this should be the final version.

R80.x Architecture and Performance Tuning - Link Collection

I wrote my first article on R80.x firewall architecture a year ago. After many hours in the lab with R80.10, R80.20, R80.30 and R80.40 many long evenings, another approximately 40 articles were added. Because I lost the overview of my articles, here is a list of links to the most interesting articles with the topics:- R80.x performance tuning- R80.x architecture- R80.x new CoreXL, SecureXL and ClusterXL functions I hope I can help you with interesting information about R80.x!

curl: (60) SSL certificate problem: unable to get local issuer certificate

Hi,I have a problem with HTTPS Inspection to access a site.When I do a curl_cli I get the error "curl: (60) SSL certificate problem: unable to get local issuer certificate".In the dashboard the certificate exists, but when I look inside the bundle certificate via ssh I can't see the root certificate.I tried to insert the certificate by hand, and when I curl with the --cacert $CPDIR/conf/ca-bundle.crt parameter no error is displayed, but when I curl without specifying the path, which should take the default path, I get the same error.Does anyone have any ideas how to resolve this error?

Failover between different HW with cphacu

Hi wonderful checkmates!I got a quick question for you:I just want to do a zero downtime upgrade.I’m upgrading R77.20 4400 to 5600 brand new appliances with R80.30.Do you think with different HW the cluster will be in Active/Down and cphacu start will work? I’ve never tried it before but I think with the same CoreXL instances it will work.D!Z
