Intrusion Detection and Prevention System (IDPS) traffic between the sensor and the security management or sensor data collection servers must traverse a dedicated Virtual Local Area Network (VLAN) logically separating IDPS traffic from all other enclave traffic.

Overview

Review the network topology diagram and interview the ISSO to determine how the IDPS traffic between the sensor and the security management or sensor data collection servers is transported.

If the IDPS traffic does not traverse a dedicated VLAN logically separating IDPS traffic from all other enclave traffic, this is a finding.

Fix Text (F-54728r805974_fix)

Design a communications path for OOB traffic or create a VLAN for IDPS traffic to protect the data.
