What IBM z/OS Communications Server can do for your business

IBM® z/OS® Communications Server, a high availability enterprise transaction and data server, provides common applications, such as FTP, Telnet and the remote execution of applications. Built for optimum productivity, it provides a secure platform for developing and sharing mainframe workloads.

IBM z/OS Encryption Readiness Technology (zERT) Network Analyzer, a new z/OSMF plugin, is now available for you to easily query and analyze the cryptographic protection attributes of your z/OS TCP/IP and Enterprise Extender connections.

Things you should know about z/OS Encryption Readiness Technology (zERT)

Benefits

High-speed connectivity

Supports high-bandwidth and high-speed networking technologies, including Shared Memory Communications (SMC), which provides significant performance improvements for TCP protocol workloads.

High availability

Uses z/OS Parallel Sysplex® technology to enable high availability application support.

Network security

Protects sensitive data and the operation of the TCP/IP stack on z/OS.

IPv6 enablement

Enables IPv6, the successor to aging IPv4 technology, to handle the demands of internet usage with 128-bit addressing.

Network management

Collects network topology, status, and performance information.

Simplification and usability

Finanz Informatik

"zERT brings all the requested information that we need for our security business and to achieve our described security policy. I am using the zERT Reports in my daily business. For us, zERT is a big relief! We have used the zERT aggregation records to totally eliminate the TLS 1.0 protocol and SHA1/HMAC suites. zERT reporting also enabled us to find various problems in environment settings and configurations. I think we never would have had a chance to do this without the zERT support!"

Fiducia & GAD IT AG

Read the case study

Fiducia & GAD IT AG is in the process of enabling z/OS Enterprise Readiness Technology (zERT) to monitor and record the cryptographic protection attributes of network connections terminating on z/OS. With zERT, Fiducia & GAD IT AG can determine which of the connections are properly or improperly configured. This could potentially help the company in its efforts to simplify compliance reporting.
