IBM zERT Network Analyzer
IBM® zERT (z/OS® Encryption Readiness Technology) Network Analyzer is a web-based graphical user interface that z/OS network security administrators can use to analyze and report on data reported in zERT Summary records.
z/OS V2R3 Communications Server introduced a new feature called z/OS Encryption Readiness Technology (zERT). zERT positions the TCP/IP stack to act as a focal point for collecting and reporting the cryptographic security attributes of IPv4 and IPv6 TCP and Enterprise Extender (EE) connection traffic that is protected using the TLS/SSL, SSH and IPSec cryptographic network security protocols. Connection data is written to z/OS System Management Facility (SMF) in two new SMF type 119 records:
- zERT Connection Detail (subtype 11) records are written on a per-connection basis to record the cryptographic protection history of a given TCP or EE connection.
- zERT Summary (subtype 12) records 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.
To get a quick start with IBM zERT Network Analyzer, see IBM zERT Network Analyzer tutorial.

Dependency:
- The IBM zERT Network Analyzer task requires either Db2® 11 for z/OS or Db2 12 for z/OS.
