ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question
Your team plans to integrate an open-source JSON parsing library that a developer downloaded from an unofficial mirror. To establish the component's origin and trustworthiness before it enters the build pipeline, which action delivers the most reliable assurance?
Compile the library with all compiler warnings and errors enabled.
Validate the library's PGP signature against the public key published on the project's official website.
Download the same version from several mirrors and compare their file sizes.
Review community forum discussions to gauge whether other developers trust the library.
Validating the library's PGP (or other cryptographic) signature with the public key distributed by the project owners confirms both authenticity (the code really came from the expected source) and integrity (it has not been altered). Merely compiling with strict warnings does nothing to prove provenance, comparing file sizes could miss injected changes of equal length, and reading forum comments is subjective and non-technical. Cryptographic signature verification is therefore the strongest control.
