TMA-AIX-5.2.9

Ensure minimum password length is configured

HighLevel 1Automatedaix

Description

The minimum password length setting determines the lowers number of characters that make up a password for a user account. There are many different theories about how to determine the best password length for an organization, but perhaps "passphrase" is a better term than "password". The minlen option sets the minimum acceptable size for the new password. Audit: reads `lssec -f /etc/security/user -s default -a minlen`.

How it is checked

Audit method: Shell command

shell

command -v lssec >/dev/null 2>&1 || exit 1; out=$(lssec -f /etc/security/user -s default -a minlen 2>/dev/null) || exit 1; v=$(printf '%s\n' "$out" | sed -n 's/.*minlen=\([^ ]*\).*/\1/p'); if [ -n "$v" ] && [ "$v" -ge 14 ]; then echo compliant; else echo "minlen=$v"; fi

Expected output: compliant

How it is fixed

Fix method: Shell command

shell

chsec -f /etc/security/user -s default -a minlen=14
