The BIG-IP Core implementation must continuously monitor inbound communications traffic crossing internal security boundaries for unusual or unauthorized activities or conditions.
An XCCDF Rule
Description
<VulnDiscussion>If inbound communications traffic is not continuously monitored, hostile activity may not be detected and prevented. Output from application and traffic monitoring serves as input to continuous monitoring and incident response programs. Internal monitoring includes the observation of events occurring on the network crossing internal boundaries at managed interfaces such as web content filters. Depending on the type of ALG, organizations can monitor information systems by monitoring audit activities, application access patterns, characteristics of access, content filtering, or unauthorized exporting of information across boundaries. Unusual/unauthorized activities or conditions may include large file transfers, long-time persistent connections, unusual protocols and ports in use, and attempted communications with suspected malicious external addresses.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

If the BIG-IP Core performs content filtering as part of the traffic management functionality, configure the BIG-IP Core as follows:
Configure a policy in the BIG-IP ASM module to continuously monitor inbound communications traffic crossing internal security boundaries for unusual or unauthorized activities or conditions.
Apply ASM policy to the applicable Virtual Server(s) in BIG-IP LTM module to continuously monitor inbound communications traffic crossing internal security boundaries for unusual or unauthorized activities or conditions.
