An Intrusion Detection and Prevention System (IDPS) sensor must be deployed to monitor the network segment hosting web, application, and database servers.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-18492	NET-IDPS-018	SV-20027r2_rule		Medium

Description
Attacks can originate within the enclave boundary. Hence, deploying an IDPS on the network segment hosting web, application, and database servers is imperative. The servers are critical resource and the network segment hosting them will receive the most traffic within the enclave. Deploying IDPS on this network is promotes defense-in-depth principles that will enable operations to detect attacks quickly and take corrective actions.

Check Text ( C-21126r3_chk )
Review topology of the network segment hosting the web, application, and database servers. If this segment is not being monitored by an IDPS sensor, this is a finding.

Fix Text (F-19914r2_fix)
Implement an IDPS strategy to monitor the network segment hosting web, application, and database servers.
