The F5 BIG-IP appliance providing content filtering must protect against or limit the effects of known and unknown types of denial-of-service (DoS) attacks by employing pattern recognition pre-processors.
The F5 BIG-IP appliance providing content filtering must protect against or limit the effects of known and unknown types of denial-of-service (DoS) attacks by employing pattern recognition pre-processors. An XCCDF Rule
The F5 BIG-IP appliance providing content filtering must protect against or limit the effects of known and unknown types of denial-of-service (DoS) attacks by employing pattern recognition pre-processors.
Medium Severity
<VulnDiscussion>If the network does not provide safeguards against DoS attacks, network resources will be unavailable to users.
Installation of content filtering gateways and application layer firewalls at key boundaries in the architecture mitigates the risk of DoS attacks. These attacks can be detected by matching observed communications traffic with patterns of known attacks.
Detection components that use pattern recognition pre-processors can detect attacks when signatures for the attack do not exist or are not installed. These attacks include zero-day attacks which are new attacks for which vendors have not yet developed signatures.
This requirement applies to the communications traffic functionality of the ALG as it pertains to handling communications traffic, rather than to the ALG device itself.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
