# Penetration test prep

A pentest is only worth its price if the scope is honest, the rules keep it
safe, and the findings actually get fixed and re-tested. The common failures
bracket the engagement: a vague scope that wastes days on the wrong assets, a
missing rules-of-engagement doc that turns a test into an outage, and a
report that lands in a drawer while the same holes stay open.

## Method

1. **Define scope as concrete assets, not adjectives.** List exact domains,
   IP ranges, API base URLs, mobile builds, and account tiers in and out of
   scope. "Our platform" invites the tester to guess; an explicit inventory
   plus named exclusions (third-party SaaS you cannot authorize) keeps the
   effort where it pays.
2. **Write rules of engagement before anyone connects.** Agree on the test
   window, permitted intensity, whether social engineering and
   denial-of-service are allowed, a data-handling clause for anything
   sensitive found, and an emergency stop contact. Get written authorization
   from the asset owner: testing without it is a crime, not a test.
3. **Choose the access model deliberately.** Decide black-box, gray-box, or
   white-box, and provision test accounts at each privilege level, staging
   credentials, and source or API docs accordingly. A gray-box test with real
   accounts finds authorization flaws a pure black-box run never reaches.
4. **Test against staging that mirrors production, or plan for production
   care.** Point testers at an environment with production-like config and
   seeded data, not live customer records. If production is in scope, agree on
   rate limits and a rollback plan so a payload does not corrupt real data.
5. **Triage findings by real risk, not the report's raw severity.** Re-rate
   each issue against your exposure and data sensitivity, deduplicate, and
   assign an owner and a due date proportional to severity. A "medium" on an
   internet-facing auth endpoint outranks a "high" behind a VPN.
6. **Remediate, then demand a retest of each fix.** Patch, and have the tester
   or your team verify the specific finding is closed, since a fix that
   addresses the symptom often leaves the class open. Track every item to
   closed in the same tracker as normal work.

## Litmus tests

- Could the tester list exactly which hosts and accounts are in scope from
  your brief alone?
- Is there signed authorization and a named emergency-stop contact before the
  window opens?
- Does each finding have an owner, a due date, and a retest, not just a
  severity label?
- Are the fixes verified closed rather than marked done on assertion?

## Boundaries

This covers commissioning and consuming a pentest, not performing one, and
not the continuous scanning and dependency work that should run between tests
(see dependency-auditing). A pentest is a point-in-time sample, not proof of
security: findings are a floor on your problems, never a ceiling.
