Check Text ( C-42651r1_chk )
Check the system audit configuration to determine if file and directory deletions are audited. # cat /etc/audit/audit.rules | grep -e "-a exit,always" | grep -i "unlink" If no results are returned, or the results do not contain "-S unlink", this is a finding.

Fix Text (F-38699r1_fix)
Edit the audit.rules file and add the following line to enable auditing of deletions: -a exit,always -S unlink Restart the auditd service. # rcauditd restart OR# service auditd restart
