ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

During a penetration test of a newly developed RESTful service that enforces role-based access control over encrypted TLS, you must confirm that authorization rules cannot be bypassed via insecure direct object references (IDOR). Which test activity will BEST demonstrate the effectiveness of this security control?

  • Inject extremely large JSON payloads into request bodies to determine if the service crashes under abnormal input sizes.

  • Modify resource identifiers in authenticated API requests to attempt access to objects owned by another user and observe the response.

  • Capture and replay TLS handshake packets to test the service's resistance to replay attacks.

  • Generate a high volume of concurrent requests to verify that rate-limiting prevents service exhaustion.
