A Verifiable Execution Record is a structured log of execution events, usually signed or otherwise tamper-evident, that shows what an automated system did and how each action changed system state. Instead of recording only final output, it preserves the chain of commands, tool calls, and resulting state transitions.
This matters in cyber security because traditional logs often show that something happened, but not who triggered it, what tool was used, or whether the history was altered after the fact. In AI-agent and automation environments, a verifiable record can help investigators reconstruct incidents, confirm accountability, and detect unauthorized actions. Defenders may use it for audit trails, incident response, and policy enforcement, while attackers may try to evade it by using unlogged paths, separate processes, or channels outside the capture boundary. A Verifiable Execution Record is strongest when paired with access control, sandboxing, and independent telemetry.
