ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

During a code review you learn that a web application issues sequential numeric session IDs, transmits them over plain HTTP, and stores them in a cookie that can be read by client-side scripts. What single change will most effectively harden the session lifecycle against hijacking and eavesdropping attacks?

  • Hash the sequential ID with MD5 before placing it in the existing cookie.

  • Require HTTPS for the entire site and set the session cookie with both Secure and HttpOnly attributes.

  • Replace the numeric ID with a signed JSON Web Token stored in browser localStorage.

  • Increase the session timeout from 30 minutes to 12 hours so users log in less frequently.
