Interpretation and response

Windows reported a successful IIS NetworkCleartext logon. Review the account, application and transport configuration.

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 logon type describes credential handling by the authentication package; the alert alone does not establish that credentials crossed the network without transport encryption.

Documentation
