# Gaia Hardening

This document 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 R82 is based on Red Hat 8 version and the Linux kernel 4.18.0-372.**

The applications removed from the Red Hat operating system include X Windows, Office applications, games, and many other applications that are irrelevant to Firewall operations.

This document describes the remaining packages and modifications to the system.

- The list of RPMs does not include Check Point application packages that are installed on the Gaia system.
- The list only applies to the Gaia operating system hardening.
- Gaia OS is derived from a Red Hat Linux distribution.
- The source code for these modified packages is available for review, as described in the **License.txt** file on the Gaia distribution media.
- The hardening of some Gaia components, such as those requiring external network communications, was audited by Check Point staff and by an independent security consulting organization.
