CA VM:Secure product Config Delay LOG option must be set to 0.
Medium Severity
<VulnDiscussion>IBM z/VM 6.4.0 made changes to obscure whether a logon is invalid due to the user ID or due to the password. Both the logon prompting sequence and the message HCPLGA050E were changed. However, DELAYLOG causes a delay for a logon with an invalid password that it does not cause when the user ID is invalid. Thus, if you are using DELAYLOG with z/VM 6.4.0, you can inadvertently let someone trying to break into your system know that it is the password that is invalid.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
