ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

To avoid per-call fees and request limits while verifying authentication, input validation, and error handling in a new e-commerce checkout service that invokes a third-party tax API, the team will test in staging. Per CSSLP guidance on simulated testing, which approach best meets this need without calling the live provider?

  • Import a recent production database snapshot into QA and run manual functional tests against the live tax API.

  • Commission an external black-box penetration test against the production site to uncover exploitable flaws in the checkout process.

  • Create virtual instances of the tax-calculation service in a staging environment and execute a suite of automated synthetic checkout transactions covering normal and error paths.

  • Rely solely on static code analysis of the checkout module to identify input-handling vulnerabilities before release.
