Any products to protect MVS software from cracking and reverse engineering?
In these days I study about reverse engineering and cracking in PC and protection of your product from bad actions in your code. This area is very inters thing to learn. Tools like Ollydbg, IDA pro make the code in PC totally un protected and no software can be safe with these debugger. Learning these tools make me thing about MVS. There are also, in MVS, debuggers and even slip which can enable us easily to crack any product. The most important slip is the instruction fetch (IF) with action equal trace. With this slip, anybody can see any MVS command and the contents of its registers by tracing any code in MVS. The slip is HW tracing, bit are set in the PSW (per) and in control registers and easily trace any code the hackers like. In PC the software companies try to make the life of hackers hard by using anti debugger tools to make the hackers confuse but eventually these action make the debugging in PC harder for more minutes or hours but nobody can protect the PC software from being cracked. Any tool in MVS to protecting code from being explore by reverse engineering? In my exploration I found some ways to have some protection to your code, but I am only in start point. I know that MVS is not PC but any tools to protect your code from being cracked using MVS debugger or per slip?
