CorreLog, Inc. Announces General Availability of its Latest Release of zDefender® Version 5.8.3, for Real-time Security and Compliance Monitoring on IBM® z/OS®

This latest release of the mainframe information security and compliance product features enhancements to events from Compuware and Micro Focus and now supports the consumption of z/OS console messages and JES JOBLOG SYSOUT to allow the capture of additional events that do not go through IBM®’s z/OS System Management Facility or SMF.

Naples, FL, August 13, 2018CorreLog, Inc., the leader in multi-platform IT security event log management, today announced its latest release of zDefender® is now Generally Available. The latest release of CorreLog’s mainframe Security Information & Event Management or SIEM product, includes a multitude of enhancements to bring real-time mainframe security visibility into Windows- and UNIX-based enterprise SIEM tools. Though IBM touts its IBM Z as the most powerful transaction system for cloud (i.e. $8 trillion in credit card payments yearly, 30 billion transactions per day, 29 billion ATM transactions yearly), the preferred platforms for securing enterprise data are exclusive to Windows and UNIX systems. This was the genesis of CorreLog building zDefender®; to provide these distributed SIEM systems an easy-to-install, easy-to-use mainframe security product with real-time visualization and alerting of mainframe events through a standard web browser or SIEM system.

“We all came up through the ranks on the mainframe side of enterprise software,” said George Faucher, CorreLog president and founder. “And about 10 years ago we saw this huge gap in how long it was taking privileged user event data to go from the mainframe to distributed security tools and decided to do something about it. The result was zDefender® (previously known as SIEM Agent for z/OS) – software code we put on z/OS that SIEM tools could access to get RACF, ACF2, Top Secret and other mainframe event data into their systems as the events were generated in real time.”

CorreLog’s zDefender® for z/OS is currently Generally Available, and the version 5.8.3 upgrade includes the following enhancements:

  • Support for z/OS CONSOLE message streaming
  • Support for dynamic JES JOBLOG (batch job) output streaming, including active SYSOUT from long-running started tasks
  • New utility for bulk loading of any flat file into zDefender®
  • INHIBIT now supported for all SMF record types
  • Support for JSON-format SIEM messages
  • Support for Compuware Abend-AID (z/OS reliability and quality) and Application Audit
  • Support for Micro Focus ChangeMan (mainframe change management) events
  • Approximately 400 additional CICS (online transaction management and connectivity) fields
  • “Surrogate for” USERID enrichment
  • Plus several other enhancements

CorreLog recommends that existing customers update to zDefender® version 5.8.3. The upgrade package is easy to deploy, and existing customers may upgrade to this latest version themselves by contacting CorreLog support here for their download package. Alternately, customers may contact CorreLog support here for upgrade assistance.
