Software has been developed around any aspect of technology in the last few years. It has become a core part of every device, not only for personal use but also in industrial and automotive environments. A direct raise in security issues has come with its spread, particularly for programs executing in third-party contexts. A company's income might rely on software operating on devices it does not own (take smartphones for example). If physical control is not an option, an attacker can open the device, attach a debugger and potentially tamper its software. The only possible defense is to detect these attacks and take the proper countermeasures.
