The Cisco ASA must be configured to block traffic from IP addresses that have a known bad reputation based on the latest reputation intelligence.
An XCCDF Rule
Description
<VulnDiscussion>Configuring the network element to delete and/or quarantine based on local organizational incident handling procedures minimizes the impact of this code on the network. Malicious code includes, but is not limited to, viruses, worms, trojan horses, and spyware. The code provides the ability for a malicious user to read from and write to files and folders on a computer's hard drive. Malicious code may also be able to run and attach programs, which may allow the unauthorized distribution of malicious mobile code. Sometimes it is 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 preferred action is for the file to be quarantined for further investigation. This requirement is limited to network elements that perform security functions, such as ALG and IDPS.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
