The ALG providing content filtering must delete or quarantine malicious code in response to malicious code detection.
An XCCDF Rule
Description
<VulnDiscussion>Taking an appropriate action based on local organizational incident handling procedures minimizes the impact of this code on the network. The ALG must be configured to block all detected malicious code. It is sometimes acceptable/necessary to generate a log event and then automatically delete the malicious code; however for critical attacks or where forensic evidence is deemed necessary, the file should be quarantined for further investigation. This requirement is limited to ALGs web content filters and packet inspection firewalls; that perform malicious code detection as part of their functionality.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
