Audit Trail May 2026

| Feature | Simple Log (e.g., Syslog) | True Audit Trail | | :--- | :--- | :--- | | | Current state ("Server is at 80% CPU") | Sequence of events ("User X changed Y at Z time") | | Immutability | Often overwritten or rotated | Append-only; deletion is impossible or strictly controlled | | Chaining | No cryptographic link between entries | Often uses cryptographic hashing or blockchain to link entries (tamper-evident) | | Forensic Value | Low (can be altered retroactively) | High (any alteration breaks the chain) |
