Windows Logon Events

Prev Next

Windows event logs are collected via the Windows Event Log API.The table describes the Windows event logs monitored by Logon Tracker. The “LT Assigned Status” column reflects the status that Logon Tracker assigns to each event. These statuses are relevant to the module configuration (see Configuring Logon Tracker Agent Policy) and the UI search functionality (see Search Controls.

Note

Always review your domain audit policy to ensure that success and failure logon events are being audited. For example, default policies that exclude auditing of successful logons, will drastically reduce the value of Logon Tracker.
