The A10 Networks ADC must generate alerts to the administrators and ISSO when accounts are modified.
Medium Severity
<VulnDiscussion>Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply modify an existing account. Notification of account modification is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail which documents the modification of device administrator accounts and notifies administrators and Information System Security Officers (ISSO). Such a process greatly reduces the risk that accounts will be surreptitiously modified and provides logging that can be used for forensic purposes. The A10 Networks ADC records in the audit log when an account is modified. 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>
