Description

<VulnDiscussion>The use of security policy filters provides protection for the confidentiality of data by restricting the flow of data. A crucial part of any flow control solution is the ability to configure policy filters. This allows the operating system to enforce multiple and different security policies. Policy filters serve to enact and enforce the organizational policy as it pertains to controlling data flow.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
