The ALG that intermediary services for FTP must inspect inbound and outbound FTP communications traffic for protocol compliance and protocol anomalies. An XCCDF Rule
The ALG that intermediary services for FTP must inspect inbound and outbound FTP communications traffic for protocol compliance and protocol anomalies.
Medium Severity
<VulnDiscussion>Application protocol anomaly detection examines application layer protocols such as FTP 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 which exploit weaknesses of commonly used protocols.
Since protocol anomaly analysis examines the application payload for patterns or anomalies, an FTP proxy must be included in the ALG. This ALG will be configured to inspect inbound and outbound FTP 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>
