Immutable Audit Trail
A technical logging mechanism that guarantees records cannot be modified, deleted or overwritten once created. It achieves traceability, integrity and verifiability through cryptographic hash chains and digital signatures.
Timeline (last 90 days)
An immutable audit trail is a technical recording mechanism: once a record is created, it cannot be modified, deleted, or overwritten, guaranteeing the traceability, integrity, and verifiability of all operations.
True immutability must be embedded in the persistence layer, and any attempt at tampering leaves a detectable trace: the record's hash value changes, and the complete hash chain breaks.
If there is an error in an immutable record that has already been written, the original record cannot be modified; the correct approach is to publish a new correction event that references the ID of the erroneous record, with the reason for correction and a signature attached.
