SPARTA President’s Corner
contributed by Randy Springs
Daylight Saving Time is over, and hopefully, the hot, humid days so common in North Carolina. For some of us, basketball season will replace a dismal football season. Others are trying to get in last minute vacation days to avoid losing them at the end of the year. And yes, the holiday commercials have begun too early.
Our speaker this month will be Jim Elliott of GlassHouse Systems, speaking on LinuxOne and Linux on z Systems capacity and solution planning. I know that my company continues to exploit the benefits of server consolidation on the mainframe. Come hear about the benefits and capacity considerations for servers on z Systems.
Please plan to join everyone for chicken, networking, and education on Tuesday, November 7 at 6:15 p.m. at our usual LabCorp location.

We need ideas and volunteers for future speakers. Presentations don’t have to be fancy, just informative and interesting. Even a 5 or 10 minute talk can start an interesting interaction. Contact Ron Pimblett by phone as noted below.

zERT Monitors Your Encrypted z/OS Network Traffic
Contributed By Ed Webb
"Imagine being directed by your manager to identify the overall quality of the cryptographic protection for your z/OS network. What exposures do you have? Who is using unapproved protection protocols, or worse, not using any protection at all? Where would you start?
z/OS Communications Server V2.3 introduces a new feature to provide you with what you need to answer your manager’s request: z/OS Encryption Readiness Technology (zERT). zERT allows a z/OS network security administrator to determine which TCP and Enterprise Extender (EE) traffic patterns to and from their z/OS systems meet approved network encryption policies and which don’t. It does this by collecting and recording, in SMF record format, the cryptographic protection attributes for TLS, SSL, SSH, and IPSec security sessions that terminate on the local stack.
zERT provides two functions at no charge to assist a network administrator in determining how data in flight is being protected:
zERT Discovery tracks and records significant events regarding the security sessions that are used to protect each individual application connection. zERT Discovery obtains this security information in two ways, ....
zERT Aggregation provides summary information for the security sessions terminating on the local stack. zERT Aggregation uses the information that’s accumulated by zERT Discovery as a basis for the summary records.
zERT Aggregation will be available on z/OS V2.3 with APAR PI83362 in 1Q 2018."
These excerpts should convince you to read the full 3 page article in the IBM Systems Magazine Hot Topic titled Monitor the Cryptographic Protection of Your z/OS Network Traffic. Check it out as the article was written in part by IBMers at RTP here in North Carolina.
IBM Doc Buddy App Replaces LookAt
Contributed By Ed Webb
"IBM Doc Buddy is a mobile app that enables you to search error messages of IBM Z software products. IBM Doc Buddy V2 can be a perfect replacement for LookAt, a z/OS message tool for which support is no longer available. The app is available in both Apple App Store and Google Play.
After you install the app on your smartphone or tablet, you can search for the explanation of IBM Z product messages within seconds. Apart from z/OS, z/VSE and z/VM, IBM Doc Buddy integrates the messages from products such as WebSphere MQ, z/TPF, CICS, IMS and Db2 for z/OS."
