Interpretation and response

This event is recorded as “proftpd: Multiple connection attempts from same source.” 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.

The current rule explicitly disables Active Response for this event.

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

ASL is reporting that a client has made multiple successful FTP login attempts to the system within a very short period of time (10 connections in 60 seconds).

ASL will not shun on this event, so there is no effect on the end user. We not recommend you disable this rule.
