Ensure inactive password lock is 30 days or less
HighLevel 2Automatedcos
Description
User accounts that have been inactive for over a given period of time can be automatically disabled. It is recommended that accounts that are inactive for 30 days after password expiration be disabled. Inactive accounts pose a threat to system security since the users are not logging in to notice failed login attempts or other anomalies.
How it is checked
Audit method: Shell command
shell
bad=0; [ -r /etc/shadow ] || exit 1; v=$(sed -n "s/^INACTIVE=//p" /etc/default/user[a]dd 2>/dev/null | tail -1); [ -n "$v" ] && [ "$v" -ge 0 ] && [ "$v" -le 30 ] || bad=1; for x in $(awk -F: '$2 ~ /^[^*!xX]/ && $2 != "" {print ($7==""?"-1":$7)}' /etc/shadow); do [ "$x" -ge 0 ] && [ "$x" -le 30 ] || bad=1; done; [ $bad -eq 0 ] && echo compliant || echo noncompliant- Expected output
compliant
How it is fixed
