Hacking, the act of infiltrating or using computer systems or networks, can be many things: ruthless, dastardly, however, at the same time, an effective weapon for innovation. While that might be a term we attribute to the cybercriminal world, it also relates to ethical hacking, or penetration testing provided to find, and ultimately fix vulnerabilities within a network.
