Question 1100
A SOC analyst wants to isolate a host from one correlated incident rather than close three duplicate alert tickets. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.
Explanation
Correct Answers
Correlate Cisco XDR observables, endpoint detections, email, and network events to establish incident scope and response before automating containment. This control addresses the failure mechanism and narrows the enforcement boundary. XDR brings signals across integrated controls; cross-product visibility depends on healthy connectors and source coverage. Confirm pre-change conditions using: Inspect observable sightings, integration health, incident timeline, detection confidence, and action permissions. This is the implementation portion of the complementary pair. Situation: A SOC analyst wants to isolate a host from one correlated incident rather than close three duplicate alert tickets.
Inspect observable sightings, integration health, incident timeline, detection confidence, and action permissions. This checks the relevant condition before an engineer modifies production access or detection behavior. XDR brings signals across integrated controls; cross-product visibility depends on healthy connectors and source coverage. The controlled response would be: Correlate Cisco XDR observables, endpoint detections, email, and network events to establish incident scope and response before automating containment. This supplies the diagnostic evidence needed for the complementary action. Situation: A SOC analyst wants to isolate a host from one correlated incident rather than close three duplicate alert tickets.
Incorrect Answers
Guests obtain only appropriate internet access while enrolled employees reach approved internal applications under auditable policy. This step could matter for Cisco ISE guest and BYOD identity policies but is not part of the required complementary pair for this case. The paired steps are: Correlate Cisco XDR observables, endpoint detections, email, and network events to establish incident scope and response before automating containment. and Inspect observable sightings, integration health, incident timeline, detection confidence, and action permissions. Situation: A SOC analyst wants to isolate a host from one correlated incident rather than close three duplicate alert tickets.
Inspect DHCP and RADIUS attributes, device profile confidence, endpoint groups, 802.1X support, and allowed fallback policies. This step could matter for Cisco ISE profiling and endpoint identity certainty but is not part of the required complementary pair for this case. The paired steps are: Correlate Cisco XDR observables, endpoint detections, email, and network events to establish incident scope and response before automating containment. and Inspect observable sightings, integration health, incident timeline, detection confidence, and action permissions. Situation: A SOC analyst wants to isolate a host from one correlated incident rather than close three duplicate alert tickets.
Use SIEM to search and correlate security telemetry and SOAR playbooks to coordinate authorized investigative or response actions. This step could matter for SIEM and SOAR workflow distinction but is not part of the required complementary pair for this case. The paired steps are: Correlate Cisco XDR observables, endpoint detections, email, and network events to establish incident scope and response before automating containment. and Inspect observable sightings, integration health, incident timeline, detection confidence, and action permissions. Situation: A SOC analyst wants to isolate a host from one correlated incident rather than close three duplicate alert tickets.
