The simple fact of the matter is that attackers will always have several vulnerabilities to choose from at any potential victim they want to target. And security managers, even those who are really good at their jobs, will never be able to close every single hole. And it only takes one.
So if traditional information security practices are not enough, what else can we do? I've been giving that question a lot of thought lately, and I think part of the answer is to evolve our security technologies, just as the attackers evolve their techniques. That heuristic behavior-based malware detection technology I keep talking about is pretty cool, but is it still cutting-edge? It's been around for three or four years. Is there anything newer out there? And how can we choose the right technologies that are going to be effective against emerging threats but still stand the test of time so their manufacturers will be around three years from now?
There are some new products starting to go to market, and venture capitalists are funding a lot of new security technology. I think we should all keep a close eye on them. I'm beginning to believe that in the cutthroat rivalry between attacker and defender, the best technology wins. The only way we can keep one step ahead of today's hackers is to take two steps forward and advance our defensive capabilities to the point where we can reliably repel, or at least detect, today's data thieves.
