Fix Recommendation

Configure the operating system to audit the execution of privileged functions.

Add or update the following rules in "/etc/audit/rules.d/audit.rules":

-a always,exit -F arch=b32 -S execve -C uid!=euid -F euid=0 -k setuid
-a always,exit -F arch=b64 -S execve -C uid!=euid -F euid=0 -k setuid
-a always,exit -F arch=b32 -S execve -C gid!=egid -F egid=0 -k setgid
-a always,exit -F arch=b64 -S execve -C gid!=egid -F egid=0 -k setgid

The audit daemon must be restarted for the changes to take effect.

Check Contents

Verify the operating system audits the execution of privileged functions using the following command:

# grep -iw execve /etc/audit/audit.rules

-a always,exit -F arch=b32 -S execve -C uid!=euid -F euid=0 -k setuid
-a always,exit -F arch=b64 -S execve -C uid!=euid -F euid=0 -k setuid
-a always,exit -F arch=b32 -S execve -C gid!=egid -F egid=0 -k setgid
-a always,exit -F arch=b64 -S execve -C gid!=egid -F egid=0 -k setgid


If both the "b32" and "b64" audit rules for "SUID" files are not defined, this is a finding.

If both the "b32" and "b64" audit rules for "SGID" files are not defined, this is a finding.
