Monitoring cryptographic network protection: z/OS encryption readiness technology (zERT)

z/OS® Encryption Readiness Technology (zERT) is a Communications Server feature that provides information about the cryptographic network protection state of TCP and Enterprise Extender connections terminating on a z/OS system. zERT helps you answer the following questions:

• What TCP and Enterprise Extender traffic is being protected (and which is not)?
• How is that traffic being protected? For instance, what protocols are being used, which cryptographic algorithms are being used, and what key lengths?
• Who on my z/OS system is consuming or producing the network traffic, whether it is protected or not?
• Where is the remote endpoint for that traffic?
