The VMM must enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period.

Description

<VulnDiscussion>By limiting the number of failed login attempts, the risk of unauthorized VMM access via user password guessing, otherwise known as brute-forcing, is reduced. Limits are imposed by locking the account. This restriction may be relaxed for administrative accounts to avoid potential Denial of Service.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
