UnverifiedA fail-closed design holds only for the operations the hook actually covers; if an equivalent path has no hook registered, the system is effectively fail-open for that path, and single-point fail-closed cannot be used to infer overall security.60% similarUnverifiedThe fail-closed principle requires that a system default to blocking rather than defaulting to allowing when it fails, and in security engineering the former is almost always recommended.56% similarUnverifiedOpenSeal does not provide exactly-once guarantees for external tools; leases can only ensure a task will be retried and cannot roll back side effects that have already occurred, so irreversible operations require the business layer to implement its own idempotency checks.54% similarUnverifiedFail-open refers to defaulting to allow passage under abnormal conditions, as opposed to fail-closed.53% similar
