Type I and Type II Errors – The Heart of Event Processing

Opher Etzion begins to discuss one of the topics I consider to be the heart of event processing in his post, On False Positives and False Negatives.

Statistically speaking, false positives are called Type I errors (α errors) and false negatives are called Type II errors (β errors).

If you are interested in “getting to the heart” of complex event processing, visit this link.   I’ll discuss detection theory in more detail in a future post.

The Top Ten Security Threats for 2008 (Part 13) – Summary

I have now posted eight out of the top ten cybersecurity security threats for 2008, still unordered.    Here is what we have so far:

   — Cyber masquerading to abuse, attack, blackmail, bully, extort, or molest.

   — Password and identity theft from phishing, spyware, malware and theft of hardware.

   — Criminal use of botnets and botnet-like technologies.

   — Cyberbullying, cyberterrorism and other forms of electronic violence.

   — Subversion of democratic political processes.

   — Criminal manipulation and subversion of financial markets.

   — Spying by governments, industry and criminals.

   — Denial-of-service attacks.

 Eight threats down, two to go.    Your comments and suggestions are welcome!
