Issue/Introduction

You have been told that all processes using SSL3 must be upgraded to use the TLS security protocol. You would like to know if you just need to specify PROT=TLS in CCISSL to accomplish this, and what can be expected by making this change.

From the CA COMMON SERVICES 14.1 REFERENCE GUIDE, page 150:

  PROT=

  Specifies which security protocols are enabled:

  SSL - Only SSL Version 3 (default)

  TLS - Only TLS Version 1

  SSL/TLS | TLS/SSL | S/T | T/S | BOTH - Both SSL Version 3 and TLS Version 1 are enabled.

 

With this keyword value not specified in the CCLSSL proc, you are running with SSL Version 3 (default).

Resolution

The change that needs to be made now is to add TLS. Update the PARM= statement included on the EXEC PGM= card. Add PROT=TLS and save your changes.

The above change will be transparent to you, and no additional changes need to be made.

To activate the above change, stop/start the CCISSL task (e.g. P CCISSL). The task will automatically be restarted by CAIENF.
