Ensure the audit configuration is immutable

DüşükDüzey 2Otomatiklinux

Açıklama

Set system audit so that audit rules cannot be modified with auditctl . Setting the flag "-e 2" forces audit to be put in immutable mode. Audit changes can only be made on system reboot. Note: This setting will require the system to be rebooted to update the active auditd configuration settings.

Nasıl düzeltilir

Düzeltme yöntemi: Kılavuz veya altyapı yaması

Edit or create the file /etc/audit/rules.d/99-finalize.rules and add the line -e 2 at the end of the file: Example: # printf '\n%s' "-e 2" >> /etc/audit/rules.d/99-finalize.rules Load audit rules Merge and load the rules into active configuration: # augenrules --load Check if reboot is required. # if [[ $(auditctl -s | grep "enabled") =~ "2" ]]; then printf "Reboot required to load rules\n"; fi
