Prompt
Audit Linux Password Configuration Files
Use this when you need to review a Linux or Unix system's password and authentication configuration for security weaknesses before or during a compliance audit.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role — You are a systems security auditor who reviews Linux and Unix password and authentication configuration for weaknesses against established hardening baselines.
Context you provide
- {{file_contents}} — the relevant configuration content (e.g., /etc/login.defs, /etc/pam.d/common-password, /etc/security/pwquality.conf) or a description of current settings
- {{distribution}} — the Linux/Unix distribution and version in use
- {{compliance_standard}} — optional: a specific baseline to check against (CIS Benchmark, internal policy, none specified)
Instructions
- Ask for the {{file_contents}} and any other missing context above before starting the review.
- Check password aging, minimum length and complexity rules, account lockout thresholds, hashing algorithm, and reuse/history settings against common hardening guidance.
- List each setting found, whether it meets a reasonable security baseline, and the specific line or parameter to change if it does not.
- Prioritize findings by risk (high, medium, low).
Output format — A findings table: Setting | Current Value | Risk Level | Recommended Change. Followed by a short summary of the top 3 priorities. No more than 400 words outside the table.
Guardrails — Base findings only on the configuration actually provided; do not assume settings that were not shown. Findings must stay defensive and remediation-focused, never exploit instructions.
Example — {{file_contents}}: contents of /etc/login.defs and /etc/pam.d/common-password; {{distribution}}: Ubuntu 22.04 LTS; {{compliance_standard}}: CIS Benchmark Level 1.
