What is the role of tamper-evident storage in logging?

Tamper-evident storage focuses on preserving the integrity and authenticity of logs. By using an append-only design, cryptographic hashes that chain entries together, accurate time stamps, and sometimes digital signatures, any alteration to past logs becomes detectable. This makes it clear if someone tries to modify records after they’re written, which is crucial for audits, investigations, and maintaining trust in the logging system. This approach doesn’t speed up log generation, nor does it replace encryption. Encryption protects confidentiality, not integrity, and tamper-evident measures address the ability to detect changes. It also doesn’t by itself guarantee offline availability, which is about accessibility and backup strategies.
