Third-Party Ai Api Security Assessment

Objective

Evaluate third-party AI APIs for security, privacy, and compliance posture.

Control / requirement

Contractual security requirements + penetration testing + data flow mapping.

Business impact

Third-party API breaches become organisational breaches. Estimated exposure: $500k–$5M per vendor.

Validation approach

Test ID: D4-CTL-05-VTS-001 Test Type: Manual Test Design: Request security assessment for critical third-party AI API; verify compliance. Execution Steps: 1. Identify critical AI APIs 2. Request SOC 2/security report 3. Verify data handling & encryption 4. Document gaps Pass Criteria: assessment_obtained_within_12_months = True; encryption_verified = True; data_handling_compliant = True Independent Verification: Auditor reviews vendor security packages and contracts.

Expected evidence

Not separately specified in the available source.

Mapping and source

Not separately specified in the available source.

Implementation guidance

Translate the requirement into system-specific procedures, responsible roles, technical configurations and review conditions. Retain evidence showing both design and operating performance. Where the source provides no separate implementation instruction, do not infer that a single technical mechanism is sufficient.

Assessment considerations

  • Confirm scope and applicability.
  • Inspect control design and responsible ownership.
  • Test representative operation and adverse conditions where appropriate.
  • Evaluate evidence provenance, completeness and contradictory evidence.
  • Record limitations and notably absent outcomes.
