Ensure maxexpired is configured

MediumLevel 1Automatedaix

Description

Defines the number of weeks after maxage, that a password can be reset by the user. The maxexpired attribute limits the number of weeks after password expiry that a password may be changed by the user. Audit: reads `lssec -f /etc/security/user -s default -a maxexpired`.

How it is checked

Audit method: Shell command

shell

command -v lssec >/dev/null 2>&1 || exit 1; out=$(lssec -f /etc/security/user -s default -a maxexpired 2>/dev/null) || exit 1; v=$(printf '%s\n' "$out" | sed -n 's/.*maxexpired=\([^ ]*\).*/\1/p'); if [ -n "$v" ] && [ "$v" -ge 0 ] && [ "$v" -le 4 ]; then echo compliant; else echo "maxexpired=$v"; fi

Expected output: compliant

How it is fixed

Fix method: Shell command

shell

chsec -f /etc/security/user -s default -a maxexpired=4
