Automated Investigation & Response
Understanding the Concept
Automated Investigation and Response (AIR) automatically investigates alerts and takes remediation actions. When an alert triggers, AIR examines evidence, expands investigation to related entities, and determines recommended or automatic actions.
AIR runs in three modes: fully automated, semi-automated (approval required), and no automated response. The level is configured per device group.
Actions include isolating devices, quarantining files, disabling accounts, and blocking URLs. All actions are logged and reversible.
Key Points
- AIR automatically investigates alerts and recommends actions
- Three automation levels: full, semi, none
- Configured per device group
- Actions are logged, auditable, and reversible
- Common actions: isolate device, quarantine file, disable account
Why This Matters in Real Organizations
SOC teams are overwhelmed with alerts. AIR handles routine investigation automatically, freeing analysts for complex threats. Organizations report 70% reduction in manual investigation time.
