The BIG-IP Core implementation must be configured to inspect for protocol compliance and protocol anomalies in inbound SMTP and Extended SMTP communications traffic to virtual servers. An XCCDF Rule
The BIG-IP Core implementation must be configured to inspect for protocol compliance and protocol anomalies in inbound SMTP and Extended SMTP communications traffic to virtual servers.
Medium Severity
<VulnDiscussion>Application protocol anomaly detection examines application layer protocols such as SMTP to identify attacks based on observed deviations in the normal RFC behavior of a protocol or service. This type of monitoring allows for the detection of known and unknown exploits that exploit weaknesses of commonly used protocols.
Since protocol anomaly analysis examines the application payload for patterns or anomalies, an SMTP proxy must be included in the ALG. This ALG will be configured to inspect inbound SMTP and Extended SMTP communications traffic to detect protocol anomalies such as malformed message and command insertion attacks.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
