Ensure audit logs are not automatically deleted
LowLevel 2Automatedlinux
Description
The max_log_file_action setting determines how to handle the audit log file reaching the max file size. A value of keep_logs will rotate the logs but never delete old logs.
How it is checked
Audit method: Shell command
shell
alt0() { command -v grep >/dev/null 2>&1 || { echo "step1: grep not installed"; return 1; }; o=$(bash -c 'grep max_log_file_action /etc/audit/auditd.conf' 2>&1); printf '%s\n' "$o" | tr -s ' \t' ' ' | sed 's/^ //;s/ $//' | grep -Fxq -- 'max_log_file_action = keep_logs' || { echo step1: missing 'max_log_file_action = keep_logs'; return 1; }; }; if alt0; then echo compliant; fi- Expected output
compliant
How it is fixed
Fix method: Guidance or infrastructure patch
Set the following parameter in /etc/audit/auditd.conf: max_log_file_action = keep_logs
