Meaning
Verification methods prove that the automated records of a computer system are genuine and complete. Effective system log authentication involves checking digital signatures and sequence numbers to ensure no logs were deleted or added. This process governs the trust placed in the internal history of a digital environment.
Access Proof
Identity checks confirm which user or process created a specific entry in the history. When system log authentication is applied, it links every action to a specific credential. This creates a record that can prove who was present in a system at a specific time.
Tamper Detection
Algorithmic tests reveal if any part of the historical record has been modified. A failure in system log authentication indicates that the history is no longer reliable. This forces a founder to look for other sources of proof to support a claim about past events.
Identity Link
Cryptographic keys bind a set of logs to a specific piece of hardware or a verified organization. The value of system log authentication is the ability to prove that the logs came from the actual system in question and not a simulation. This costs the organization the time to manage the keys and the processing power to sign every log entry.
