The Palo Alto Networks security platform must deny or restrict detected prohibited mobile code.

An XCCDF Rule

Description

<VulnDiscussion>Mobile code is defined as software modules obtained from remote systems, transferred across a network, and then downloaded and executed on a local system without explicit installation or execution by the recipient. This applies to mobile code that may originate either internal to or external from the enclave. Mobile code is defined as software modules obtained from remote systems, transferred across a network, and then downloaded and executed on a local system without explicit installation or execution by the recipient. The Palo Alto Networks security platform allows customized profiles to be used to perform antivirus inspection for traffic between zones. Antivirus, anti-spyware, and vulnerability protection features require a specific license. There is a default Antivirus Profile; the profile inspects all of the listed protocol decoders for viruses, and generates alerts for SMTP, IMAP, and POP3 protocols while denying for FTP, HTTP, and SMB protocols. However, these default actions cannot be edited and the values for the FTP, HTTP, and SMB protocols do not meet the requirement, so customized profiles must be used.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
