The Palo Alto Networks security platform must have a DoS Protection Profile for outbound traffic applied to a policy for traffic originating from the internal zone going to the external zone.

An XCCDF Rule

Description

<VulnDiscussion>The Palo Alto Networks security platform must include protection against DoS attacks that originate from inside the enclave which can affect either internal or external systems. These attacks may use legitimate or rogue endpoints from inside the enclave. Installation of Palo Alto Networks security platform 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. To comply with this requirement, the Palo Alto Networks security platform must inspect outbound traffic for indications of known and unknown DoS attacks. Sensor log capacity management along with techniques which prevent the logging of redundant information during an attack also guard against DoS attacks. This requirement is used in conjunction with other requirements which require configuration of security policies, signatures, rules, and anomaly detection techniques and are applicable to both inbound and outbound traffic.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure

Go to Objects >> Security Profiles >> DoS Protection
Select "Add" to create a new profile.
In the "DoS Protection Profile" window, complete the required fields.
For the Type, select "Classified".
In the "Flood Protection" tab, "Syn Flood" tab, select the "Syn Flood" check box and select either "Random Early Drop" (preferred in this case) or "SYN Cookie".   
In the "Flood Protection" tab, "UDP Flood" tab, select the "UDP Flood" check box; complete the "Alarm Rate", "Activate Rate", "Max Rate", and "Block Duration" fields.
