Definition
An authentication token created for the purposes of deceiving an adversary.
How it works
Usage of decoy session tokens may be monitored to track attacker behavior or otherwise control the beliefs of the attacker.
Considerations
- Interaction and activity with the decoy session token must be constantly monitored and analyzed to detect unauthorized activity.
- Session tokens are typically short-lived and therefore the decoy must be continuously updated to provide the appearance of it being used in the production environment.
- Automated tools can assist with maintenance and updates by automatically adjusting the decoy session token and environment to mimic the production environment.
Implementation perspective
Decoy Session Token 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 the relevant system, activity, and evidence sources.
Use the technique to present controlled information, services, or artifacts that shape adversary behavior and create observable interaction.
Questions to ask
- What behavior is the deceptive element intended to attract, delay, reveal, or redirect?
- How is the deceptive element made plausible without creating unacceptable operational risk?
- Which interactions are monitored, and who investigates them?
- How is the deceptive environment isolated from production systems and sensitive data?
Evidence and validation
- Design records describing the deception objective and placement
- Isolation and containment test results
- Monitoring and alert-routing configuration
- Interaction records and documented investigative outcomes
Common failure patterns
- The deceptive element is obvious, stale, or inconsistent with the surrounding environment.
- Interactions are collected but not reviewed or connected to response processes.
- The decoy introduces a new pathway to production data or systems.
