Medical Mutual Gains Fast Access to z/OS Log Data via Splunk and Ironstream

Running Syncsort’s Ironstream and leveraging Splunk Enterprise, Medical Mutual of Ohio has now implemented mainframe security in real time through the Splunk® Enterprise platform. One goal is to help protect customer information stored in DB2 from unauthorized access. Syncsorts’s Ironstream, a utility, collects and forwards z/OS log data, including security data, to Splunk Enterprise and Splunk Enterprise Security.

“We’ve always had visibility. Now we can get it faster, in real time directly from the mainframe,” said the insurer’s enterprise security supervisor. Previously, the company would do a conventional data transfer, which could take several hours. The new approach, sometimes referred to as a big iron-to-big data strategy, now delivers security log data in near real time. This enables the security team to correlate all the security data from across the enterprise to effectively and quickly gain visibility into user-authentication data and access attempts tracked on the mainframe. And they can do it without needing specialized expertise or different monitoring systems for z/OS.

Real-time analytics, including real-time predictive analytics, are increasingly attractive as solutions for the growng security challenges organizations are facing. These challenges are due, in large part, to the explosion of transaction activity driven by mobile computing, and soon, IoT, and Blockchain, most of which eventually finds its way to the mainframe. All of these present immediate security concerns and require fast, nearly instant security decisions. Even cloud usage, which one would expect to be mainstream in enterprises by now, often is curtailed due to security fears.

With the Ironstream and Splunk combination, Medical Mutual Medical Mutual can see previously slow-to-access mainframe data alongside other security information it was already analyzing in Splunk Enterprise. Splunk Enterprise enables a consolidated enterprise-wide view of machine data collected across the business, which makes it possible to correlate events that might not raise suspicion alone but could be indicative of a threat when seen together.

The deployment proved to be straightforward. Medical Mutual’s in-house IT team set it up in a week with Syncsort answering deployment questions to assist. Although there are numerous tools to capture log data from the mainframe, the insurer chose to go with the Splunk-Ironstream combination because it already was using Splunk in house for centralized logging. Adding mainframe security logs was an easy step. “This was affordable and it saved us from having to learn another product,” the security supervisor added. Medical Mutual runs a z13, model 409 with Ironstream.

According to the announcement, by having Ironstream leverage z/OS log data via Splunk Enterprise, Medical Mutual has enables the organization to:

  • Track security events and data from multiple platforms including IBM z/OS mainframes, Windows and distributed servers and correlate the information in Splunk Enterprise for better security.
  • Diagnose and respond to high severity security issues more quickly since data from across the entire enterprise is being monitored in real time.
  • Provide monthly and daily reporting with an up-to-the-minute account of unusual user activity.
  • Detect security anomalies and analyze their trends – the cornerstone of Security Information and Event Management (SIEM) strategies.

Real time monitoring with analytics has proven crucial for security. You can actually detect fraud while it is taking place and before serious damage is done. It is much harder to recoup loses hours, days, or, what is often the case, months later.

The Splunk platform can handle massive amounts of data from different formats and indexes and decipher and correlate security events through analytics. Ironstream brings the ability to stream mainframe security data for even greater insights, and Ironstream’s low overhead keeps mainframe processing costs low.

To try the big iron-to-big data strategy organizations can download a free Ironstream Starter Edition and begin streaming z/OS Syslog data into Splunk solutions. Unlike typical technology trials, the Starter Edition is not time-limited and may be used in production at no charge. This includes access to the Ironstream applications available for download on Splunkbase.
