Question 453
An incident at the retail fraud response desk is escalated to a SOC automation specialist after forensic evidence quality assessment reveals: A detection record contains a file path, engine name, quarantine action and local endpoint identifier but no network flow data. Do not reclassify a detection as malicious solely from a signature identifier. Operations needs evidence that the proposed defense remains effective after a routine service restart. Which targeted defensive analysis or remediation action most directly addresses the stated failure while honoring the constraints?
- Choose a permissioned full-packet capture if application payload reconstruction is required.
- Apply the approved stateful session policy so response packets are associated with an established authorized connection.

This alternate observation is collected from a second routed segment with different sensor coverage and timestamped NAT mappings; preserve raw flow direction and explicitly label whether application data or only transport metadata was available. Which targeted defensive analysis or remediation action most directly addresses the stated failure while honoring the constraints?
- Treat Tor exit nodes as egress infrastructure and seek authenticated identity and host evidence for attribution.
- Apply encryption for confidentiality and a verifiable signature for origin and integrity according to separate requirements.
- Distinguish enforcement-capable inline IPS placement from passive out-of-band IDS monitoring.
- Inspect SOAR job execution status and endpoint acknowledgment rather than treating initiation as completion.
