The organization must implement a deep packet inspection solution when protecting perimeter boundaries.
An XCCDF Rule
Description
<VulnDiscussion>Deep packet inspection (DPI) examines the packet beyond the Layer 4 header by examining the payload to identify the application or service. DPI searches for illegal statements, predefined criteria, malformed packets, and malicious code, thereby enabling the IA appliances to make a more informed decision on whether to allow or not allow the packet through. DPI engines can delve into application centric information to allow different applications to be protected in different ways from different threats. Examples of DPI appliances include next-generation firewalls, application layer gateways as well as specific gateways for web, email and SSL traffic.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Implement a deep packet inspection solution at the enclave boundaries. Verify any IA appliances used for deep packet inspection are connected, properly configured, and actively inspecting all ingress and egress network traffic.
