Over the years, we have evolved from the single point of protection on mainframes and Unix servers to networks. With that evolution, we developed the notion of defense-in-depth (yes, we have that on mainframes after a fashion, but with networks it became a completely different story). Now we were looking at gateways and such things as firewalls, UTMs and, ultimately, intrusion prevention systems. Then someone started thinking about the endpoints. Of course, there already was anti-virus on the endpoints, but thinking about the vulnerability of the endpoints took a bit of a leap and we started to see such things as access control and DLP. Before we knew it, an entire genre of endpoint security was born.
