The A10 Networks ADC must generate alerts to the administrators and ISSO when accounts are removed.
An XCCDF Rule
Description
<VulnDiscussion>When application accounts are removed, administrator accessibility is affected. Accounts are utilized for identifying individual device administrators or for identifying the device processes themselves. In order to detect and respond to events that affect administrator accessibility and device processing, devices must audit account removal actions and, as required, notify the appropriate individuals so they can investigate the event. Such a capability greatly reduces the risk that device accessibility will be negatively affected for extended periods of time and also provides logging that can be used for forensic purposes. The A10 Networks ADC records in the audit log when an account is removed. This appears as the command that created the account and contains the keyword "admin". These messages must be forwarded to the ISSO and administrators. Configuring the device to forward all audit log messages to an actively monitored syslog server or SNMP management station meets this requirement.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
