A deny-by-default security posture must be implemented for traffic entering and leaving the enclave.
An XCCDF Rule
Description
<VulnDiscussion>To prevent malicious or accidental leakage of traffic, organizations must implement a deny-by-default security posture at the network perimeter. Such rulesets prevent many malicious exploits or accidental leakage by restricting the traffic to only known sources and only those ports, protocols, or services that are permitted and operationally necessary. Applications, protocols, TCP/UDP ports, and endpoints (specific hosts or networks) are identified and used to develop rulesets and access control lists to restrict traffic to and from an enclave.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
