Assessment Title

Rule Text

TOSS must prevent the use of dictionary words for passwords.

Description

Discussion Text

If TOSS allows the user to select passwords based on dictionary words, then this increases the chances of password compromise by increasing the opportunity for successful guesses and brute-force attacks.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

if [ ! -f "/etc/security/pwquality.conf" ] && [ ! -L "/etc/security/pwquality.conf" ]; then echo "PASS"; exit 0; fi
if grep -q "^\\s*dictcheck\\s*=\\s*1\\s*$" /etc/security/pwquality.conf; then echo "PASS"; exit 0; fi
for file in /etc/pwquality.conf.d/*.conf; do
    if [ -f "$file" ] && grep -q "^\\s*dictcheck\\s*=\\s*1\\s*$" "$file"; then echo "PASS"; exit 0; fi
done
echo "FAIL"; exit 1

Remediation

Configure TOSS to prevent the use of dictionary words for passwords.

Add or update the following line in the "/etc/security/pwquality.conf" file or a configuration file in the /etc/pwquality.conf.d/ directory to contain the "dictcheck" parameter:

dictcheck=1
