Description
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.

At the command line, execute the following command to obtain a list of setuid files: # find / -xdev -perm -4000 -type f -o -perm -2000 -type f Execute the following command for each setuid file found in the first command: # grep /etc/audit/audit.rules Replace with each path found in the first command. If each does not have a corresponding line in the audit rules, this is a finding. A typical corresponding line will look like the following: -a always,exit -F path= -F perm=x -F auid>=1000 -F auid!=4294967295 -k privileged
