A rollback procedure is a documented, controlled process for returning a system or configuration to a known-good state after a change causes problems. It may restore an earlier software version, network policy, device configuration, or data backup. A reliable plan identifies what will be reverted, who is authorized to act, and how the result will be verified.
In cybersecurity, rollback limits disruption when a deployment introduces a vulnerability, breaks monitoring, or triggers unexpected behavior. In operational technology, an unsafe change can affect availability or physical processes, so rollback steps should be tested and coordinated with operations staff. Defenders should preserve recovery points, define approval and access controls, and ensure rollback does not reintroduce known vulnerabilities. For integrations that may alter network policy, a tested rollback helps keep visibility tools from becoming a source of operational risk.
