Interpretation and response

This event is recorded as “SSHD authentication failed.” 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

SSH authentication failed.

What you should do

This means a single ssh login failed, due to an invalid account of password. This is an atomic rule used by composite rules to look for multiple login failures from single sources. No actions are required.

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 atomic event and the rule should not be disabled.
