Episode 7 — Explain Digital Signatures for Integrity, Nonrepudiation, and Trust Decisions
This episode explains digital signatures as a control for integrity and sender assurance, clarifying how signing differs from encryption so you can choose the correct mechanism when protecting software, documents, and operational approvals. You will learn how signatures bind content to an identity, how verification works in practice, and why signature validation is a decisive step when assessing whether an update, configuration change, or instruction should be trusted. We cover realistic interpretations of nonrepudiation, including what signatures can and cannot guarantee when accounts are compromised or processes are weak, and we discuss operational best practices such as signing build artifacts consistently and verifying signatures before deployment. Scenarios include receiving a suspicious update, determining whether the signature is valid and meaningful, and troubleshooting common issues like signing the wrong artifact, mismatched hashes, or relying on untrusted keys.
