Ensure audit logs are not automatically deleted

低级别 2自动化linux

说明

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.

检查方式

审计方法: Shell 命令

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

预期输出: compliant
