The Palo Alto Networks security, if used as a TLS gateway/decryption point or VPN concentrator, must provide the capability to immediately disconnect or disable remote access to the information system.
An XCCDF Rule
Description
<VulnDiscussion>Without the ability to immediately disconnect or disable remote access, an attack or other compromise taking place would not be immediately stopped. Remote access functionality must have the capability to immediately disconnect current users remotely accessing the information system and/or disable further remote access. The remote access functionality may implement features such as automatic disconnect (or user-initiated disconnect) in case of adverse information based on an indicator of compromise or attack. If the Palo Alto Networks security platform is used as a TLS gateway/decryption point or VPN concentrator, configure the device to deny decrypted traffic that violates the enclave or system policies. For each type of SSL/TLS traffic that is decrypted, the resulting traffic must be inspected and filtered.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
