The A10 Networks ADC, when used for load balancing web servers, must deploy the WAF in active mode.
An XCCDF Rule
Description
<VulnDiscussion>The Web Application Firewall (WAF) supports three operational modes - Learning, Passive, and Active. Active is the standard operational mode and must be used in order to drop or sanitize traffic. Learning mode is used in lab environments to initially set thresholds for certain WAF checks and should not be used in production networks. Passive mode applies enabled WAF checks, but no action is taken upon matching traffic. This mode is useful in identifying false positives for filtering. Only Active mode filters web traffic.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
