Definition Edit

An immutable audit log is a tamper-resistant recording of how a system has been used.

Overview Edit

A system with immutable audit capabilities would, for instance, immediately and permanently record who authored, changed, or accessed information; who posed queries to the system, what the queries were, and what the responses were; and who shared information with whom, and when. This means no individual could inappropriately access information or query the system and then hide the fact from an after-the-fact audit. Inspection of the audit logs can also be controlled in a way that would require multiple parties to unlock the logs, so as to make those logs tamper resistant as well.[1]
