Enhance zERT to Detect Non AT-TLS connections.

The product only identifies traffic if it uses ATTLS for encryption. Not all products or app servers connecting to us use ATTLS. For example, MFT is AES256 and yet they show up as unsecured. Same with CICS gateway and others.

    zERT already collects TLS information from connections that do not use AT-TLS. This was an important design goal for zERT from the very beginning. There are a number of reasons zERT might report a protected connection as unprotected. Some of those reasons are addressed in Idea ZOS-I-3413 ("Enhance zERT discovery to be more accurate in recognizing and recording TLS sessions with very large handshake messages and unusual timing"). Others are documented in the z/OS Communications Server IP Configuration Guide under the heading "What are the limitations for zERT discovery?" As we learn about other conditions that can produce unexpected zERT results, we will try to document them. If you have specific connections that are producing unexpected zERT results, please open a case with the Communications Server support team so we can help you understand the data and the conditions behind it. Since the basic premise of this Idea is incorrect, this Idea is declined.
