The ALG must be configured to remove or disable unrelated or unneeded application proxy services.
Medium Severity
<VulnDiscussion>Unrelated or unneeded proxy services increase the attack vector and add excessive complexity to the securing of the ALG. Multiple application proxies can be installed on many ALGs. However, proxy types must be limited to related functions. At a minimum, the web and email gateway represent different security domains/trust levels. Organizations should also consider separation of gateways that service the DMZ and the trusted network.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
