Quintessential Event Processing: Signature Versus Anomaly Detection

Detection experts understand that the optimal detection design and architecture is generally a combination of both signature and anomaly detection engines.   In event processing, signature detection involves the real-time pattern matching analysis of events.   A core advantage of signature detection is that basic pattern matching models are easy to understand and develop [...]

Twenty Four CEP Public Presentations on SlideShare

For archiving purposes, I have uploaded 24 public CEP presentations that I presented over an 18 month period at various conferences from March 14, 2006 to September 21, 2007.  These presentations can be viewed here.  For example, my first public CEP presentation:

Comments on Proxy Caches and Web Application Security (OWASP Taipei)

Hello from Taipei.
We just completed an absolutely awesome OWASP conference (over 1200 attendees), OWASP AppSec Asia 2008 - Taiwan. This was a very well managed conference, organized by Wayne Huang, OWASP Taiwan Chapter Leader and Founder and CEO of Armorize.  In a future post, when I get links to other speaker’s presentations, I will talk [...]

OWASP AppSec Asia 2008 - Taiwan

Here is the latest on OWASP AppSec Asia 2008 - Taiwan.  I will be giving a talk on Oct 27th about Proxy Caches and Web Application Security–using the recent Google Docs 0-day as an example.
Some of the background for this presentation are Proxy Caches are a Challenging Threat to Internet Security and A New Security [...]

Proxy Caches are a Challenging Threat to Internet Security

Proxy caches, combined with poorly written session management code, can easily leads to serious security flaws similar to what we highlighted in A New Security Breach in Google Docs Revealed.
Web developers have no control over proxy caches in the Internet. However, developers do have control of the code they write and their admin teams have [...]

CEP, Event Noise and Asymmetric Event Processing

In The Genesis of Complex Event Processing: Asymmetric Capabilities I introduced the abstract concept of “asymmetric processing capabilities” to describe the foundations of complex event processing.   If you take a few moments to review the first CEP projects from Stanford University, you will see that the application of CEP was toward  solving myriad asymmetric event [...]

The 10 Top Cybersecurity Threats for 2008, AMCHAM & OWASP Thailand

Last year, in collaboration with IT security experts from (ISC)2 and the LinkedIn professional network, I published The Top Ten Cybersecurity Threats for 2008.  In a joint meeting with interested AMCHAM Thailand guests from the Open Web Application Security Project (OWASP), Thailand, Chapter, we will review the 2008 top 10 cybersecurity threats and facilitate an [...]

Fraud Detection in Financial Services Reloaded

I read an interesting post by the former CTO of out-of-business Kaskad Technology, where event processing colleague Colin Clark respectfully disagrees with my assessment of the (lack of) capabilites in current-generation “CEP engines” for detecting complex fraud in financial services.  I’ll respond with a quote from my September 2007 post,  End Users Should Define the CEP Market.
“Experienced end [...]
