Direct answer
Prepare a current inventory, written authorization, contacts, test accounts and representative test data before an assessment. Share only the information needed through an approved channel and document gaps that could limit coverage.
Collect the scope inputs
List the approved domains, environments, APIs and excluded services. Provide architecture or data-flow diagrams where useful, with a date and owner. A diagram can be stale, so the tester and service owner should reconcile differences before expanding the test.
Reference: NIST SP 800-115: Technical Security Testing and Assessment.
Prepare safe access
Create dedicated test accounts for relevant roles and known harmless records. Agree secure credential delivery, authentication requirements and account expiry. For a multi-tenant application, supply separate tenants and explain the intended sharing policy.
- Confirm written authorization and test windows.
- Name escalation and incident contacts.
- Identify third-party dependencies and testing restrictions.
Agree evidence handling
Decide where the tester should store findings, how sensitive evidence is transferred and when temporary access will be revoked. Provide an example of the evidence needed for remediation without requesting real customer data or working secrets in the report.
Reference: NIST SP 800-115: Technical Security Testing and Assessment.
Resolve gaps and monitor
Track accounts or environments that are unavailable and decide whether to delay, narrow scope or report incomplete coverage. During the engagement, provide an operations contact for unexpected degradation and record approved scope changes.
Assessment limits
Readiness improves assessment efficiency but does not guarantee complete testing or discovery of every issue. The final report should state the actual tested scope and limitations.
Frequently asked questions
Should production credentials be emailed to a tester?
Use dedicated accounts and the organization's approved secure delivery method; avoid sharing personal or long-lived credentials.
Does supplying a diagram authorize all its systems?
No. The written scope must identify the assets and activities authorized for testing.
