The document linked below describes the hardening of the Check Point Gaia operating system.
Components that are not necessary for a network security device, or that could cause security vulnerabilities, were removed.
Check Point Gaia R81 is based on Red Hat 7.6 version and the Linux kernel 3.10.0-957.
The applications removed from the operating system include X Windows, Office applications, games, and many other applications that are irrelevant to Firewall operations.
