The Juniper Networks SRX Series Gateway IDPS must protect against or limit the effects of known types of Denial of Service (DoS) attacks by employing signatures.

Description

<VulnDiscussion>If the network does not provide safeguards against DoS attack, network resources will be unavailable to users. Installation of IDPS detection and prevention components (i.e., sensors) 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 and monitoring for anomalies in traffic volume, type, or protocol usage. Detection components that use signatures can detect known attacks by using known attack signatures. Signatures are usually obtained from and updated by the IDPS component vendor. These attacks include SYN-flood, ICMP-flood, and Land Attacks. This requirement applies to the communications traffic functionality of the IDPS as it pertains to handling communications traffic, rather than to the IDPS device itself. The Juniper SRX must be configured with screens using the Firewall STIG to protect against flood and DOS attacks type attacks, but must also be configured for anomaly-based protection</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
