Remember when firewalls first became popular? When enterprises began installing firewalls in earnest, they quickly defined our network’s protective perimeter. Over the years, this perimeter has evolved from a hardware focus to one more defined by software, to where Bruce Schneier officially proclaimed their ultimate death a few years ago.
Part of this evolution is the changing nature of the attacks we experience along with the changing nature of our enterprise networks. In my blog post for RSA today, I review this evolution and talk about how we are all out, as that wise infosec sage Jerry Seinfeld mentions in his first monologue for his TV series above. What we have come to is that endpoint detection and response tools have to do a lot more these days than just scan for malware and compromises.
