The Juniper SRX Services Gateway VPN must ensure inbound and outbound traffic is configured with a security policy in compliance with information flow control policies.

Description

<VulnDiscussion>Remote access devices, such as those providing remote access to network devices and information systems, which lack automated, capabilities increase risk and makes remote user access management difficult at best. Remote access is access to DoD non-public information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network. Automated monitoring of remote access sessions allows organizations to detect cyber attacks and also ensure ongoing compliance with remote access policies by auditing connection activities of remote access capabilities, from a variety of information system components (e.g., servers, workstations, notebook computers, smart phones, and tablets). In phase-2, another negotiation is performed, detailing the parameters for the IPsec connection. New keying material using the Diffie-Hellman key exchange established in phase-1 is used to provide session keys used to protecting the VPN data flow. If Perfect-Forwarding-Secrecy (PFS) is used, a new Diffie-Hellman exchange is performed for each phase-2 negotiation. While this is slower, it makes sure that no keys are dependent on any other previously used keys; no keys are extracted from the same initial keying material. This is to make sure that, in the unlikely event that some key was compromised; no subsequent keys can be derived.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
