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.
z/OS TCP/IP Encryption Compliance Analysis
Security policies and standards such as FIPS-140-2 require data transmissions to be encrypted with specific standards. Ensuring and proving encryption compliance on mainframes is of course, as important as it is for other platforms.
zERT: Breakthrough in Visibility for Managing Encryption of Network Traffic
This article, originally published in Cheryl Watson’s Tuning Letter 2019 No. 4, provides a great introduction to zERT and ways to increase the benefit you can derive from this data.
Mainframe Security’s Latest Tool for Ensuring Encryption Standards are Met
zERT data can enable the mainframe security team to both evaluate ongoing adherence to security policies and programmatically provide data for required reporting to auditors and compliance officers.
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.
