5 Key Factors of Complexity

Brian J. Truskowski, General Manager of Internet Security Systems (ISS), gave a keynote presentation at RSA 2009. His talk touched on an interesting topic that he referred to as the “5 Key Factors of Complexity.”

He identifies that the key cause of compromise is human nature; the ability that humans are susceptible to social engineering. Instead of focusing on securing systems, Mr. Truskowski argues that we should design systems that are “resistant to human frailty.” He goes on to state, that designing these systems (by reducing complexity) is difficult.

According to Mr. Truskowski, the 5 key factors of complexity and the key to designing these systems are:

  1. Threats
  2. Compliance
  3. Technology
  4. Economics
  5. Business Needs

Contrary to security, Businesses have to keep focused on all of these factors or they will be unsuccessful. Vendors however, are according to Mr. Truskowski, only focused on one of these factors… Threats. He argues, If an enterprise doesn’t focus on compliance, they are fined. If a business doesn’t focus on business needs, the business can’t change.

“It’s like building the titanic. The ship’s designers optimized around being able to withstand collisions at the sacrifice of maneuverability. There have been many theories over the years over why the Titanic sank, from Brittle steel to sub-standard rivets. But, in reality, it is obvious why the Titanic sank. It couldn’t get out of the way of the iceberg. The Titanic’s designers focused on size, strength, resilience, and luxury but not on maneuverability.”

I think Mr. Truskowski’s talk was the hidden gem at RSA. It is an interesting idea for security vendors to begin focusing on things other than threats. Of course, if the idea gets legs, it will be 10-15 years before any change occurs. It is great to see people thinking holistically about security.

Verizon’s 2009 Data Breach Investigation Report

Verizons 2009 Data Breach Investigation Report

Verizon’s annual data breach investigation report came out last week, and I finally had a chance to read through it. I read others security bloggers synopsis of it but none of them seemed to point out anything that was interesting to me.

Here is the interesting bit that I found: Verizon actually recorded someone using XSS as an attack vector.

Typically, it is very difficult to find anything on-line that points to people using XSS maliciously. Most of the time, XSS is used to increase page views (recent Mikeyy worm) or for popularity (Sammy Worm).

We, the security community, now have some type of hard evidence to explain how XSS could potentially be an issue for companies. Is this enough to bring awareness to management?
