CA API Gateway ALG Security Technical Implementation Guide
SRG-NET-000512-ALG-000066
The CA API Gateway that provides intermediary services for HTTP must inspect inbound and outbound HTTP traffic for protocol compliance and protocol anomalies.
The CA API Gateway that provides intermediary services for HTTP must inspect inbound and outbound HTTP traffic for protocol compliance and protocol anomalies. An XCCDF Rule
The CA API Gateway that provides intermediary services for HTTP must inspect inbound and outbound HTTP traffic for protocol compliance and protocol anomalies.
Medium Severity
<VulnDiscussion>Application protocol anomaly detection examines application layer protocols such as HTTP 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 HTTP proxy must be included in the ALG. This ALG will be configured to inspect inbound and outbound HTTP communications traffic to detect protocol anomalies such as malformed message and command insertion attacks.
All inbound and outbound traffic, including HTTPS, must be inspected. However, the intention of this policy is not to mandate HTTPS inspection by the ALG. Typically, HTTPS traffic is inspected either at the source or destination and/or is directed for inspection by organizationally-defined network termination point.
The CA API Gateway must be configured to inspect incoming and outgoing HTTP traffic for protocol compliance and anomalies such as limiting message size, protecting against code injection cross-site request forgery, SQL attacks, and XML and JSON document structure validation; validate content; and/or use third-party anti-virus scanning. Also, regular expressions can be used to detect any known attack patterns within policies.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
