Log Correlation Engine 4.8.3 Release Notes - 10/30/2017

The following notes describe the changes that are included in Log Correlation Engine (LCE) version 4.8.3, significant enhancements to LCE, and information about upgrading.


  • Added Targeted IDS support for SourceFire version 6.2
  • Improved input validation of LCE login username field to prevent potential application issues caused by invalid characters
  • Continued improvements to LCE memory usage
  • Added better controls to mitigate password guessing attacks - admin account will be locked out after 5 unsuccessful login attempts
  • Raised TASL VM limit to 100 MB each, allowing TASLs to store more temporal information for correlation
  • Exposed sensor name to TASL scripts to allow users to pivot on the host / sensor name rather than relying only on IP addresses when TASLs are triggered

Security Enhancements:

  • Upgraded cURL/libcurl to version 7.56.1 to apply the latest security updates
  • Disabled 3DES cipher in LCE web server
  • Updated OpenSSL to version 1.0.2l

Resolved Items:

  • Fixed an issue where duplicate data sensor information and wrong timestamps were appearing in client and syslog sections of the LCE web UI
  • Fixed an issue that could cause the disk to fill with TASL abort log messages
  • Fixed a High Availability issue which could prevent the backup LCE server from taking over if primary server is brought down
  • Fixed an issue that caused the LCE daemon to restart with the 'Unable to reload the policy map' error
  • Fixed an issue that resulted in errors during processing of multiline attribute values in LCE policies and rendered the policy invalid
  • Fixed an issue where policy entries in Client Assignment Rules were being truncated if multiple client policies were added to a rule
  • Fixed an issue that could cause LCE to restart if plugins are reloaded while processing certain data
  • Fixed an issue that was causing the 'Next Step' button to be disabled on the Quick Setup Port Configuration page
  • Fixed intermittent LCE crashes caused by stopping of lce_tasld process
  • Stopped addition of duplicate syslog headers, when forwarding data via UDP or TCP event forwarding rules
