Detect memory intrusion

Question

There are software applications, such as ArtMoney, that edit the memory of other applications.

Is there a way to detect when some other application is editing the memory of my application?

Answer 1

The basic idea to protect from basic memory modification is to encrypt the parts of memory you care about, and have redundant checks to ensure against modification.

None of which will stop a determined hacker, but it's sufficient to keep the script kiddies out of your address space.
