Need Confirmation on Correct IOC CSV Format for Threat Prevention Policy

Chinmaya_Naik — Mon, 22 Jul 2024 05:35:52 GMT

Dear Community Team,

We are currently facing an issue with installing the Threat Prevention policy and require your assistance to confirm the correct format for our IOC CSV file.

Here is the context of our current situation and the formats we are using:

Existing Format:

Wrong Format (Not sure):

We are particularly concerned about the formats for different types of indicators such as FILENAME, Mutex, and Email. Furthermore, we want to ensure we are using the correct order of columns in our CSV file. Which of the following orders is correct?

UNIQ-NAME, VALUE, TYPE, PRODUCT, CONFIDENCE, SEVERITY, COMMENT
UNIQ-NAME, VALUE, TYPE, CONFIDENCE, SEVERITY, PRODUCT, COMMENT

Your assistance in confirming the correct format and order for the indicators will help ensure our configuration is compliant with the Checkpoint SmartConsole GUI client requirements.

Regards

Hello Check Point Community,

Thank you @PhoneBoy Sir.

I recently encountered an issue with the installation of the Check Point Threat Prevention Policy and wanted to share the steps taken to resolve it. This might help others facing similar issues.

Issue: The Threat Prevention Policy installation failed due to incorrect formatting and unsupported types in our Custom Intelligence Feeds CSV file.

Solution: Through thorough review and correction, we successfully resolved the issue. Below are the detailed steps and technical explanations.

Step 1: Identify the Correct Order of Columns:

Correct Order:
Based on the Check Point R81.20 Threat Prevention Administration Guide, the CSV file must follow this column order:

UNIQ-NAME
VALUE
TYPE
CONFIDENCE
SEVERITY
PRODUCT
COMMENT

Step 2: Supported Indicators and Types:

Supported Formats for Indicators:

URL
Domain
IP
IP Range
MD5
Mail-subject
Mail-from
Mail-to
Mail-cc
Mail-reply-to
SHA1 (in Security Gateway versions R80.40 and higher)
SHA256 (in Security Gateway versions R80.40 and higher)

Supported Types: (In my Issue)

URL
MD5
SHA1
SHA256

Unsupported Types: (In my Issue)

HASH
Mutex

Step 3: Review and Correct CSV File:

Corrections Made:

Ensured the columns followed the correct order.
Removed unsupported types (e.g., HASH and Mutex).
Verified that all indicators use supported types and formats.

Corrected Format:

UNIQ-NAME	VALUE	TYPE	CONFIDENCE	SEVERITY	PRODUCT	COMMENT
observ1	https://file.io/M9ofMokBC1TN	URL	High	High	AV	Malicious URL
observ2	http://117.253.14.152:57028/Mozi.a	URL	High	High	AV	Malicious URL
observ3	866a9452ac62e73773c09a1e0209142a	MD5	high	high	AV	Malicious Hash
observ4	4d50315e3841aeee6bb05f7529489939	MD5	high	high	AV	Malicious Hash
observ5	8f609f60dd82dc13878b1d82ebc56e5056cb9274234df1510ee737e62ba22aaa	SHA256	high	high	AV	Malicious Hash
observ6	90f7d3f354a1637d7467962fe87449532881d06ed76acaae696cc286cba02de7	SHA256	high	high	AV	Malicious Hash
observ7	5186eb42f2d1a652f9fee0cdf3788b492582aca0	SHA1	high	high	AV	Malicious Hash
observ8	2faff8718f8f0ee4dcd0be5eb987b77e47961742	SHA1	high	high	AV	Malicious Hash

Step 4: Import Corrected CSV File:

After making the necessary corrections, we imported the CSV file into the Check Point Threat Prevention system. The policy installation was successful without any errors.

Conclusion:

Ensuring the CSV file is formatted correctly and only includes supported indicator types is crucial for the successful installation of the Check Point Threat Prevention Policy. This process has strengthened our security posture and streamlined our threat prevention measures.
