Identify and Remediate Unencrypted Traffic

IBM’s zERT (z/OS Encryption Readiness Technology) positions the TCP/IP as the focal point for collecting and reporting on cryptographically protected (and unprotected) traffic.

IntelliMagic Vision allows network security administrators to take advantage of an intuitive, GUI-based web reporter to easily navigate, report on, and analyze data reported on TCP/IP and zERT SMF 119 records.

Deriving Insights from SMF 115 MQ Statistics Data

SMF 115 MQ Statistics records report metrics at the MQ queue manager level. These records are lightweight and have negligible CPU cost, so sites typically generate MQ Statistics records on an ongoing basis.

IBM’s TCP/IP zERT Feature

TCP/IP’s zERT feature provides a single source to determine which traffic is cryptographically protected by protocols like TLS, SSH, and IPSec, and which is not protected.

For traffic with recognized cryptographic protection, you can determine which cryptographic protocol is used, which cryptographic algorithms are used, the length of the cryptographic keys, and other important attributes of the cryptographic protection. This information is valuable for determining regulatory compliance and for identifying connections that might need stronger cryptographic protection.

zERT data is produced by zERT Summary (SMF 119 subtype 12) records, which are written on a per-security-session basis at the end of each SMF interval to summarize the repeated use of security sessions during the interval.

Understand and Evaluate Cryptographic Protocols

IntelliMagic Vision for z/OS TCP/IP and zERT automatically analyzes zERT Summary records and provides additional, enhanced analysis, including:

  • Categorizing “traffic classes” based on IP address ranges
  • Defining traffic classes by:
    • Sysplex – between z/OS sysplexes (“intra” or “inter”)
    • Local – to other platforms within the data center
    • Partner – external traffic with “special” partners
    • Public – all other external traffic
  • A free-form “IP Label” can also be assigned to further describe IP ranges
  • Translates all of the more than 600 raw codes from zERT records into readable text for cipher suite, encryption algorithms, and message authentication types.
