If the system is not configured to audit certain activities and write them to an audit log, it is more difficult to detect and track system compromises and damages incurred during a system compromise.

Verify the operating system generates audit records when successful/unsuccessful attempts to use the "rmdir" syscall occur. Check the file system rules in "/etc/audit/audit.rules" with the following commands: Note: The output lines of the command are duplicated to cover both 32-bit and 64-bit architectures. Only the lines appropriate for the system architecture must be present. # grep -iw rmdir /etc/audit/audit.rules -a always,exit -F arch=b32 -S rmdir -F auid>=1000 -F auid!=4294967295 -k delete -a always,exit -F arch=b64 -S rmdir -F auid>=1000 -F auid!=4294967295 -k delete If there are no audit rules defined for the "rmdir" syscall, this is a finding. |

Configure the operating system to generate audit records when successful/unsuccessful attempts to use the "rmdir" syscall occur. Add the following rules in "/etc/audit/rules.d/audit.rules": Note: The rules are duplicated to cover both 32-bit and 64-bit architectures. Only the lines appropriate for the system architecture must be configured. -a always,exit -F arch=b32 -S rmdir -F auid>=1000 -F auid!=4294967295 -k delete -a always,exit -F arch=b64 -S rmdir -F auid>=1000 -F auid!=4294967295 -k delete The audit daemon must be restarted for the changes to take effect. |
