UNTIMED COACHING

Practice before the pressure

Use feedback to correct the model, not merely memorize an option position.

GUIDED PRACTICE

Practice the lesson questions

Answer normal lesson questions without a timer. Every answer includes an explanation, and incorrect answers can be tried again before continuing.

Connect the roles in Endpoint Detection and Response BasicsKeep endpoint sensor, endpoint telemetry, detection logic, and investigation graph as separate roles.
Connect the roles in Endpoint Detection and Response BasicsA topic-specific model connects four distinct roles used to reason about endpoint detection and response basics.
Endpoint serviceService observes activity on a managed host
Process recordsRecords link process file user and connection
Detection signalSignal maps endpoint behavior to a rule
Connection mapMap connects process file account and host
Verify Endpoint ResponseConnect endpoint response with its topic-specific inspection, expected outcome, and safety boundary.
