Interpretation and response

This event is recorded as “Logon Failure - Account locked out”. Review the originating log and the affected host or service to determine whether the activity was expected.

An OSSEC/HIDS event records or correlates activity. Blocking depends on the originating application and any separately configured Active Response policy; an alert alone does not prove that an attack was blocked.

What you should do

This means that the account has been locked out by Windows, typically because of too many authentication failures. This may indicate that the account is under attack, and the source(s) of the logon failures should be investigated to determine if this is an attack against other accounts. Search the GUI for additional events from the source IPs for these events.

The platform will track this logon, and if multiple events occur will issue a higher level alert that a brute force attack may be occurring.

Troubleshooting

False Positives

A legitimate event may still trigger this rule. Review the surrounding activity before deciding whether it is malicious.

Tuning Guidance

There is no guidance for tuning this rule, and the rule should not be disabled.
