• The Firewall is Dead. Long Live the Firewall!

  Recently, Roger Grimes opined that the firewall was dead.  Several folks chimed in to tell him that he was wrong, and much debate has ensued, citing reports about the nature of recent breaches, how attacks used to work, and how modern attacks work.   I think much of the misunderstanding has to do with the [...]

• Not Just for CIOs – The Role of IT is Changing Too

  It’s a little late, but I wanted to comment on a great opinion piece by Nicholas Evans in Computerworld last week. He makes several points that Brian, Matt, and I have been blogging about/around recently – the accessibility of applications and devices, the consumerization of IT, and the disintermediation of IT and the requisite role [...]

• A Wrap Up of InfoSec Europe

  It’s been a busy week at InfoSec Europe, the security event held at Earl’s Court in Kensington, London. The show continues to bring together some of the best and brightest minds in security, and that’s reflected by the level of conversations that we’ve had. Day after day, the crowds were running at a constant high, [...]

• The Jericho Botnet — Why Break A Wall When You Can Just Sneak Through?

  One of the advantages of having an automated malware detection system with distributed nodes around the world is that you get to see a lot of malware. But sometimes, something interesting stands out. That was the case when our research team discovered 42 samples of what we are now calling the “Jericho” botnet, which Bill [...]

This year the event will be held April 24th through the 26th, 2012, and Earl’s Court in the Royal Borough of Kensington will host the activities. If you haven’t been to [...]

• What Do CIOs Need to Know About Network Security?

  On the heels of my last post regarding the role of the modern CIO, I thought it would make sense to delve a little into the relationship between CIOs and network security.  Many CIOs have expressed indifference to the network security discipline (in fact, to the security discipline in general), at least until there’s some [...]

• Getting a Handle on DDoS

  Denial-of-Service (DoS) and Distributed Denial-of-Service Attacks (DDoS) have become an increasingly common problems for enterprises of all sizes. DDoS campaigns are commonly used by hacktivists to embarrass or otherwise disrupt a target company or government agency. Unfortunately, the problem doesn’t stop there. Botnets controlled by criminal groups can recruit thousands and even millions of infected [...]

• Weighing in on the Role of a Modern CIO

  Just read a great byline piece by Irving Wladawsky-Berger in the Wall Street Journal on evaluating the modern CIO.  I completely agree that the old interpretation of the CIO role (internal and operational in Irving’s excellent 2×2 matrix parlance) is well understood, less and less “internal,” and to some extent, less and less interesting – [...]
