Discussion

Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised information system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Auditing the use of privileged functions is one way to detect such misuse and identify the risk from insider threats and the advanced persistent threat.

Verify OL 8 audits the execution of privileged functions. 
 
Check if OL 8 is configured to audit the execution of the "execve" system call, by running the following command: 
 
$ sudo grep execve /etc/audit/audit.rules 
 
-a always,exit -F arch=b32 -S execve -C uid!=euid -F euid=0 key=execpriv 
-a always,exit -F arch=b64 -S execve -C uid!=euid -F euid=0 key=execpriv 
 
-a always,exit -F arch=b32 -S execve -C gid!=egid -F euid=0 key=execpriv 
-a always,exit -F arch=b64 -S execve -C gid!=egid -F euid=0 key=execpriv
 
If the command does not return all lines or the lines are commented out, this is a finding.
