The A10 Networks ADC must enforce the limit of three consecutive invalid logon attempts.
An XCCDF Rule
Description
<VulnDiscussion>By limiting the number of failed logon attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced. The A10 Networks ADC must be configured to limit the consecutive invalid logon attempts. When someone attempts to log on, but fails repeatedly, the failed logon attempts and associated "user is disabled" message will be logged. Note: The user will still be prompted up to five times, even when the account is disabled at three failed logon attempts.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
