When we think of the term cybersecurity, we think of machines defending against machines. Hackers and users direct the actions of the software, but it’s the systems doing the heavy lifting. When cyber criminals attempt to bypass a bank’s firewalls to access personal financial information, we call it “hacking”. When your grandpa clicks on an email link promising him a free yacht, it’s not really a hacking problem anymore – at least, not a software hacking problem. It’s a grandpa hacking problem. More generally speaking, it’s a human problem, and is called social engineering in the field of cybersecurity. The idea is to make grandpa want to click the link, rather than simply trying to brute-force his password.
