Log Correlation Engines

Tenable Log Correlation Engine (LCE) is a software module that aggregates, normalizes, correlates, and analyzes event log data from the myriad of devices within the infrastructure. LCE also has the ability to analyze logs for vulnerabilities.

SecurityCenter performs vulnerability, compliance, and event management, but without LCE integration it does not directly receive logs or IDS/IPS events. With LCE integration, LCE processes the events and passes the results to SecurityCenter.

LCE's close integration with SecurityCenter allows you to centralize log analysis and vulnerability management for a complete view of your organization’s security posture.

Note: If you add an LCE server to SecurityCenter and enable Import Vulnerabilities, LCE data counts against your SecurityCenter license. For more information, see Licenses.

For more information, see Add a Log Correlation Engine Server.

Option Description


Name for the integrated Log Correlation Engine.


Descriptive text for the integrated Log Correlation Engine.


IP address of the integrated Log Correlation Engine.

Check Authentication

Whether SecurityCenter checks the status of authentication between itself and the LCE server.


Organizations that can access data from the integrated Log Correlation Engine.


The repositories where you want SecurityCenter to store the imported LCE data.


The port where the LCE reporter is listening on the LCE server.

Username and Password

The username and Password you want SecurityCenter to use for authentication to the LCE server to retrieve vulnerability information.

This user account must be able to make changes on the remote system to enable the SSH key exchange between SecurityCenter and LCE. The appropriate permissions level is typically root, root equivalent, or other high-level user permissions on the LCE system. SecurityCenter uses these credentials a single time to exchange SSH keys for secure communication between SecurityCenter and LCE.

Note: If remote root or root equivalent user login is prohibited in your environment, manually configure the LCE server using SSH key authentication. For more information, see Manual LCE Key Exchange.
