(This tab only appears in the Manager dialog if a Advanced Windows Collector has been added to the Installed Modules tab.)

AutoDiscovery Settings

Enable AutoDiscovery. Enables auto-discovery of Windows Axon Agents.  If TLC auto-discovers a Windows Agent, TLC creates a new Monitored AssetAn object in the TLC Configuration Manager that represents a Log SourceAny log-generating application, operating-system service, database instance, or device from which TLC collects log messages. from which TLC collects log messages directly. with the Advanced Windows Collector in the Auto-Discovered Assets Asset GroupA TLC object that may contain one or more Monitored Assets..

Notes: 1) If this setting is enabled, an auto-discovered Monitored Asset will only collect Windows Event Logs if the Asset is i) not assigned to an Asset Group, or ii) assigned to an Asset Group with the Collect Windows Event Logs setting enabled in the group's Advanced Collector CollectionThe gathering or receipt of log messages from Log Sources. tab (see Working with Asset Groups). 2) To manually create a Monitored Asset for a Windows Axon Agent (see Adding a Monitored Asset for a new Log Source), this setting must be disabled.

Output to Correlation EngineThe component of your Primary Manager responsible for identifying events of interest. To correlate events, the Correlation Engine applies Correlation Rules to the Normalized Messages received from the Normalization Engine.. If enabled, TLC automatically adds the Correlation Engine as an Output DestinationAssigned to a Monitored Asset, an Output Destination is either the Audit Logger, an Event-Management Database, or a Correlation Engine that correlates Normalized Messages. in the Monitored Asset's properties (see Table 50). 

Asset-Configuration Rules

See Working with Asset-Configuration Rules.

Audit Logger

Configuration settings for the Manager's Audit Logger.

Encrypt log messages. If enabled, this setting encrypts log messages saved in the Audit Logger File StoreConsists of a series of compressed flat files containing the log messages collected by the Manager from Log Sources, and an index of terms contained in the log messages. with the 256-AES algorithm. (Note: This setting will affect performance, but will only slightly increase the size of the data in the Audit Logger File Store.)

Save log messages from unknown hosts. If enabled, the Audit Logger will save log messages received from Log Sources for which a Monitored Asset does not exist in the Configuration Manager (see What are Collectors?).

Save log messages for all Monitored Assets. If enabled, the Audit Logger will save all log messages from Log Sources for which a Monitored Asset exists in the Configuration Manager. If disabled, the Audit Logger will only save the log messages if the Monitored Asset specifies the Audit Logger as an Output Destination.

Separate data by LocationA custom category used to classify Monitored Assets by geography.. See About Locations and the Audit Logger.

Audit Logger File Store directory. The directory in which the Audit Logger saves log messages.

Index directory. The directory in which the Audit Logger saves index entries for collected log messages.

Tips: If you change the Index directory or Audit Logger File Store directory, you must restart the TLC ManagerTripwire Log Center Manager is the core software in your TLC environment. TLC Manager collects and processes log messages from a wide variety of systems and devices. service (see Working with the TLC Manager Interface).

These fields do not support Uniform Naming Convention (UNC) paths. For example:

Correct - E:\AuditLogs\

Incorrect - \\MyAuditLogServer\AuditLogs\

Log rotation configuration

Limit number of archived Audit Logger log files. To limit the number of AuditLogger.log files retained by TLC, select this option and enter the maximum number of files to be retained in the Archived Audit Logger log files to keep field. For example, if this option is enabled, and the number of AuditLogger.log files matches the specified value, TLC will replace the oldest file when a new file is needed.

Asset DiscoveryThe process by which TLC scans a Manager's Audit Logger File Store to identify the IP addresses of Log Sources in your TLC environment for which Monitored Assets have yet to be created in your TLC Console (a.k.a., Discovered Assets).. See Discovered Assets.

Audit Logger Ext

(Secondary Managers only) This tab only appears in the Manager dialog if the Audit Logger Extension has been added to the Installed Modules tab. With the Audit Logger extension, the Manager forwards any collected log messages to another Manager's Audit Logger, rather than saving the messages locally.

Audit Logger. The Audit Logger to which the Manager forwards log messages.

Collection Times. Schedules a time when the Manager forwards collected log messages to the specified Audit Logger.

Start Time. The time of day when the Manager begins sending log messages.

End Time. The time of day when the Manager stops sending log messages.

Audit Logger File Store directory. The directory in which the Audit Logger temporarily saves log messages.

Tip: If you change the Audit Logger File Store directory, you must restart the host's TLC Manager service (see Working with the TLC Manager Interface).

Note: In previous versions of TLC, a Secondary Manager configured to forward log messages was known as a Concentrator.

RADIUS server settings

RADIUS host. The host name or IP address of a Radius server.

Secret key and Secret key (confirm). Enter and confirm the shared secret key for the Radius server. The secret key is stored in both the system database and the tlc.config file. In TLC 6.2.1 and later versions, the key is encrypted in both locations.

Note: The RADIUS fields are unavailable if the following policy is enabled in the Windows Local Security Settings on the Manager’s host system (or if TLC cannot determine the setting's status):

System Cryptography: Use FIPS compliant algorithms for encryption, hashing and signing.

Single sign-on. See Configuring Single Sign-On Authentication.

Notes: TLC saves all authentication errors in the tlc.log file.
