Definition
Restoring an email for an entity to access.
Implementation perspective
Restore Email should be treated as a technical defensive capability rather than a product checkbox. In practice, teams should define the protected scope, the conditions under which the technique acts, and the observable evidence that demonstrates the intended behavior. For this technique, likely engineering context includes Email.
Use the technique to return access, data, software, configuration, or services to a trusted and usable state after disruption or defensive action.
Questions to ask
- What trusted source or known-good state will be used for restoration?
- How is integrity verified before restored assets or access return to service?
- What dependency order and recovery priority must be followed?
- How is the restored state monitored for recurrence or hidden persistence?
Evidence and validation
- Recovery procedures, dependency maps, and restoration priorities
- Backup, image, credential, or configuration provenance records
- Integrity checks and restoration test results
- Post-restoration monitoring and acceptance records
Common failure patterns
- Recovery uses an unverified source that reintroduces the original weakness or compromise.
- Restoration order ignores service dependencies and creates avoidable outages.
- Successful startup is treated as proof of trusted recovery without integrity and security validation.

Artifacts and ontology entities
These relationships describe how D3FEND connects a defensive technique to artifacts or other ontology entities. They describe graph semantics, not a product certification.
Explicit technique relationships

Offensive-technique relationships
These relationships are generated from D3FEND graph paths and are explicitly experimental. They should be treated as hypotheses for defensive analysis—not as proof that the technique prevents, detects, or removes an offensive behavior.
