Ensure number of characters changed in new password is configured

HochStufe 1Automatisiertaix

Beschreibung

The mindiff option sets the number of characters in a password that must not be present in the old password. Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Audit: reads `lssec -f /etc/security/user -s default -a mindiff`.

So wird geprüft

Prüfmethode: Shell-Befehl

shell

command -v lssec >/dev/null 2>&1 || exit 1; out=$(lssec -f /etc/security/user -s default -a mindiff 2>/dev/null) || exit 1; v=$(printf '%s\n' "$out" | sed -n 's/.*mindiff=\([^ ]*\).*/\1/p'); if [ -n "$v" ] && [ "$v" -ge 6 ]; then echo compliant; else echo "mindiff=$v"; fi

Erwartete Ausgabe: compliant

So wird behoben

Behebungsmethode: Shell-Befehl
