ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

A DevSecOps engineer has downloaded a third-party binary to include in an application build. Before committing the component to the organization's source-code repository, the engineer wants to confirm that the file has not been modified in transit. Which action provides the strongest assurance of the component's integrity?

  • Open the binary in a hex editor and search for suspicious readable strings that might indicate malicious code.

  • Compile the library and execute the vendor's unit tests to confirm the software behaves as documented.

  • Verify that the file's byte size matches the size stated on the project's download page.

  • Generate the file's cryptographic hash locally and compare it to the hash value obtained from a trusted source.
