Discussion

Without verification of the security functions, security functions may not operate correctly, and the failure may go unnoticed. Security function is defined as the hardware, software, and/or firmware of the information system responsible for enforcing the system security policy and supporting the isolation of code and data on which the protection is based. Security functionality includes, but is not limited to, establishing system accounts, configuring access authorizations (i.e., permissions, privileges), setting events to be audited, and setting intrusion detection parameters. Selection lines in the aide.conf file determine which files and directories AIDE will monitor for changes. They follow this format: <path> <rules> The <path> specifies a file, directory or wildcard pattern to monitor. The <rules>define which attributes (hashes, permissions, timestamps, etc.) to check. Satisfies: SRG-OS-000363-GPOS-00150, SRG-OS-000445-GPOS-00199

Check Content

Verify the file integrity tool is configured to verify ACLs.

Note: AIDE is highly configurable at install time. This requirement assumes the "aide.conf" file is under the "/etc" directory.

Verify AIDE is installed with the following command:

$ sudo dnf list installed aide

Updating Subscription Management repositories.
Installed Packages
aide.x86_64                                0.16-103.el9                                @rhel-9-for-x86_64-appstream-rpms

Use the following command to determine if the file is in a location other than "/etc/aide/aide.conf":

$ sudo find / -name aide.conf

If AIDE is not installed, ask the system administrator (SA) how file integrity checks are performed on the system.
