How to allow use of SetWindowsHookEx() and WriteProcessMemory() to inject DLLs into an application ?

On a commercial cloud server, I want to use two methods in my application to inject two DLLs into the address space of a second application.

The two methods are C++ calls to SetWindowsHookEx() and WriteProcessMemory() in my application.

What instructions do I give tech support at the cloud vendor, to set up Sophos, so that my DLL injections are not blocked by Sophos?

Thanks, Pete
