External connections to the network must be reviewed and the documentation updated semi-annually.

Description

<VulnDiscussion>A network is only as secure as its weakest link. It is imperative that all external connections be reviewed and kept to a minimum needed for operations. All external connections should be treated as untrusted networks. Reviewing who or what the network is connected to empowers the security manager to make sound judgements and security recommendations. Minimizing backdoor circuits and connections reduces the risk for unauthorized access to network resources.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
