Ensure filesystem integrity is regularly checked

中级别 1自动化ros

说明

Periodic checking of the filesystem integrity is needed to detect changes to the filesystem. The audit requires an enabled and active aidecheck.timer or a cron job (root crontab, /etc/crontab, /etc/cron.*) that runs aide. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.

检查方式

审计方法: Shell 命令

shell

e=$(systemctl is-enabled aidecheck.timer 2>/dev/null)
[ "$e" = enabled ] && systemctl is-active --quiet aidecheck.timer && { echo compliant; exit 0; }
c=$( (crontab -u root -l 2>/dev/null; cat /etc/crontab /etc/cron.d/* 2>/dev/null; ls /etc/cron.daily /etc/cron.weekly 2>/dev/null) | grep -E '(^|[^#].*)\baide' )
[ -n "$c" ] && echo compliant || echo 'no aidecheck.timer or aide cron job'

预期输出: compliant
