Interpretation and response

This event is recorded as “Multiple Windows Logon Failures”. 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.

Documentation

The following guidance was migrated from the historical wiki and reviewed against the rule definition. Legacy ASL product names and interface instructions refer to the versions documented then. Use the current metadata above and your installed configuration when interpreting thresholds, notification settings and response behavior.

Description

Multiple Windows login failures detected from the same source IP. Default: 10 in 240 seconds.

What you should do

This means the same source IP has failed more than 10 times in 240 seconds. Investigate this account to see if this is an attack, or just a misconfigured account.

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, this is a generic Windows error and the rule should not be disabled.
