The title is self-explanatory.

Someone explain to me the methods to block the source hacks 1.5, even a source that contains it so that I can study, etc ... ?

You need to patch alot of places in the source, I will give you one example of something that i found in the source
Wallhack:

targetpos = newtargetpos;

Someone can edit it via memory and he can enable wall hack.
