Question 140
An analyst wants a playbook to enrich suspicious domain alerts with DNS and endpoint context before allowing isolation. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.
Explanation
Correct Answers
Use Splunk detection, field normalization, incident enrichment, and approved SOAR actions to organize security-event handling at scale. This control addresses the failure mechanism and narrows the enforcement boundary. Orchestration connects event evidence to repeatable response, but logs and playbook execution require separation of detection confidence and authorization. Confirm pre-change conditions using: Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. This is the implementation portion of the complementary pair. Situation: An analyst wants a playbook to enrich suspicious domain alerts with DNS and endpoint context before allowing isolation.
Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. This checks the relevant condition before an engineer modifies production access or detection behavior. Orchestration connects event evidence to repeatable response, but logs and playbook execution require separation of detection confidence and authorization. The controlled response would be: Use Splunk detection, field normalization, incident enrichment, and approved SOAR actions to organize security-event handling at scale. This supplies the diagnostic evidence needed for the complementary action. Situation: An analyst wants a playbook to enrich suspicious domain alerts with DNS and endpoint context before allowing isolation.
Incorrect Answers
Use MAC Authentication Bypass only for supported non-802.1X devices with restricted roles and inventory-backed policy. This step could matter for MAB fallback and printer restriction but is not part of the required complementary pair for this case. The paired steps are: Use Splunk detection, field normalization, incident enrichment, and approved SOAR actions to organize security-event handling at scale. and Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. Situation: An analyst wants a playbook to enrich suspicious domain alerts with DNS and endpoint context before allowing isolation.
A riskier session receives a stronger verification or denial decision without blocking routine authorized access unnecessarily. This step could matter for Duo Adaptive Access and SSO context but is not part of the required complementary pair for this case. The paired steps are: Use Splunk detection, field normalization, incident enrichment, and approved SOAR actions to organize security-event handling at scale. and Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. Situation: An analyst wants a playbook to enrich suspicious domain alerts with DNS and endpoint context before allowing isolation.
Inspect current session identity, NAD CoA support and shared secret, ISE authorization change, and RADIUS live logs. This step could matter for CoA session reauthorization by Cisco ISE but is not part of the required complementary pair for this case. The paired steps are: Use Splunk detection, field normalization, incident enrichment, and approved SOAR actions to organize security-event handling at scale. and Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. Situation: An analyst wants a playbook to enrich suspicious domain alerts with DNS and endpoint context before allowing isolation.
