The Mission Owner of the Infrastructure as a Service (IaaS) or Platform as a Service (PaaS) must continuously monitor and protect inbound communications from external systems, other IaaS within the same cloud service environment, or collocated mission applications for unusual or unauthorized activities or conditions.
An XCCDF Rule
Description
<VulnDiscussion>Evidence of malicious code is used to identify potentially compromised information systems or information system components. Unusual/unauthorized activities or conditions related to information system inbound communications traffic include, for example, internal traffic that indicates the presence of malicious code within organizational information systems or propagating among system components, the unauthorized exporting of information, or signaling to external information systems. Anomalies within organizational information systems include, for example, large file transfers, long-time persistent connections, unusual protocols and ports in use, and attempted communications with suspected malicious external addresses. This function may be deployed within the cloud service environment cloud access point or supporting Core Data Center (CDC).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
