ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

During an architectural design review, a colleague proposes to use the Common Vulnerability Scoring System (CVSS) as the team's sole threat-modeling approach, arguing it will identify all possible threats and guide mitigation planning. According to secure software lifecycle best practices, what is the most appropriate response?

  • Accept the plan but insist CVSS be applied early so the team can skip other time-consuming threat-modeling activities.

  • Propose replacing CVSS with the DREAD model, since DREAD is specifically designed for end-to-end threat modeling.

  • Recommend adding a methodology such as STRIDE, explaining that CVSS only scores severity after vulnerabilities are identified rather than performing threat discovery.

  • Support the idea, because CVSS fully covers identifying and prioritizing threats across the system lifecycle.
