Does your organization validate digital signatures to verify the integrity and authenticity of software before installation or use?
Explanation
Digital signature validation ensures that software has not been tampered with and comes from a legitimate source. This process typically involves checking cryptographic signatures against trusted certificates or keys to confirm that code hasn't been modified since it was signed by the developer or publisher.
Evidence could include documented procedures for signature verification, screenshots of signature validation processes, logs showing signature verification steps during software deployment, or configuration settings in deployment tools that enforce signature validation before installation.
