Allow lists of programs or versions by parameter

Currently, using the cicsrequestexit provided with the CTG (BasicCICSRequestExit) it is possible to reject requests that come from a client with a lower software version than we indicate. Similarly we could do so for those requests that try to invoke a program that is not on a list known by the exit.

However, in case of using a DSS policy to assign the CICSServer it is not possible to use this exit so it would be a good idea to allow both possibilities using a configuration parameter in ctg.ini

    Hi Anu,

    One of our clients (one of the most important banks in Spain) is happy with the way CTG’s DSS works and they wouldn't want to have to stop using it

    However, their Security/Audit department had detected a potential security risk: from a Java class any CICS program could be executed/invoked so they want to determine the programs that could be invoqued (i.e., using a list of them).

    From my point of view, it could be done adding a simple piece of code in the cicsrequestexit that controls the program requested (as stated in the CA1T) rejecting the ones not included in the list.

    Unfortunately, it could not be done as the DSS is active and cicsrequestexit could not be used.

    Another solution, even further easy for the customers, could be to include a new parm in the CTG.ini file that allows to include a list of authorized programs to be called from CTG.
