Ensure the audit configuration is immutable

RendahLevel 2Otomatislinux

Deskripsi

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.
