Ensure minalpha is configured

MediumLevel 1Automatedaix

Description

Defines the minimum number of alphabetic characters in a password. In setting the minalpha attribute, it ensures that passwords have a minimum number of alphabetic characters. Audit: reads `lssec -f /etc/security/user -s default -a minalpha`.

How it is checked

Audit method: Shell command

shell

command -v lssec >/dev/null 2>&1 || exit 1; out=$(lssec -f /etc/security/user -s default -a minalpha 2>/dev/null) || exit 1; v=$(printf '%s\n' "$out" | sed -n 's/.*minalpha=\([^ ]*\).*/\1/p'); if [ -n "$v" ] && [ "$v" -ge 3 ]; then echo compliant; else echo "minalpha=$v"; fi

Expected output: compliant

How it is fixed

Fix method: Shell command

shell

chsec -f /etc/security/user -s default -a minalpha=3
