Hi, with code signing, you can apply a signature to your programs. Compare chapter 10 of RACF Security Admin Guide. The signature is invalidated by any kind of modification to the program (e.g. by a virus). A program is rejected from being loaded in case an invalid signature is found. Cryptographic hardware helps you to manage your certificates used for the signature and it is said to check the validity somewhat faster than the CP. But crypto hardware should not be prerequisite to enable program signing.

I even understand that any program which has the capability of executing and exploiting any datasets could also be one form of virus where Racf plays a vital in restricting all the sensitive datasets. Can anyone please enlighten me the why still virus was never a big threat to mainframe PC ? I apologize if my question is not clear or it requires some more information and I am trying to google more about it but i am unable to get a precise explanation about Virus on Z/os. Please direct me to manual or URL where I can get some information about this.
