Prose
An Intrusion Detection and Prevention System (IDPS) must be deployed to monitor all unencrypted traffic entering and leaving the enclave.
Medium Severity
<VulnDiscussion>Per CJCSI 6510.01F, Enclosure A-5, Paragraph 8, "DOD ISs (e.g., enclaves, applications, outsourced IT-based process, and platform IT interconnections) shall be monitored to detect and react to incidents, intrusions, disruption of services, or other unauthorized activities (including insider threat) that threaten the security of DOD operations or IT resources, including internal misuse." An Intrusion Prevention System (IPS) allows the sensor to monitor, alert, and actively attempt to drop/block malicious traffic. An Intrusion Detection System (IDS) uses a passive method; receiving a copy of the packets to analyze and alert authorized persons about any malicious activity. While an IDS or an IPS in a passive role cannot stop the attack itself, it can typically notify and dynamically assign ACLs or other rules to a firewall or router for filtering. The preferred method of installation is to have the IDPS configured for inline mode. Only when there is a valid technical reason, should the IDPS be placed into a passive or IDS mode. For a full uninhibited view of the traffic, the IDPS must sit behind the enclave's firewall. This will allow the IDPS to monitor all traffic unencrypted, entering or leaving the enclave.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
