"Bro network" an (unfortunately named) open/free IDS that turns all your network traffic into events that can trigger scripts you write. As Nat writes, "Good pedigree (Vern Paxson, a TCP/IP elder god) despite the wince-inducing name."
While focusing on network security monitoring, Bro provides a comprehensive platform for more general network traffic analysis as well. Well grounded in more than 15 years of research, Bro has successfully bridged the traditional gap between academia and operations since its inception. Today, it is relied upon operationally in particular by many scientific environments for securing their cyberinfrastructure. Bro's user community includes major universities, research labs, supercomputing centers, and open-science communities.
Bro has originally been developed by Vern Paxson, who continues to lead the project now jointly with a core team of researchers and developers at the International Computer Science Institute in Berkeley, CA; and the National Center for Supercomputing Applications in Urbana-Champaign, IL.
The Bro Project is a member of Software Freedom Conservancy. SFC is a non-profit organization created for the purpose of supporting and protecting Free, Libre, and Open Source Software (FLOSS) projects.
The Bro Network Security Monitor
Stingrays were once the most secretive of surveillance technology: devices whose existence was so sensitive that the feds actually raided local cops and stole their crime files to stop them from being introduced in court and revealing the capability to spy on cellular phones.
Berlin-based security researcher Sébastien Kaul discovered that Voxox (formerly Telcentris) -- a giant, San Diego-based SMS gateway company -- had left millions of SMSes exposed on an Amazon cloud server, with an easily queried search front end that would allow attackers to watch as SMSes with one-time login codes streamed through the service.
Researchers at NYU and U Michigan have published a paper explaining how they used a pair of machine-learning systems to develop a "universal fingerprint" that can fool the lowest-security fingerprint sensors 76% of the time (it is less effective against higher-security sensors).
Ever wondered what it takes to make the transition from amateur photography to a full career? If you answered “a better camera,” you’re half right.

Anyone can learn piano, but don’t tell that to the bored kids who had to endure hours of “Chopsticks” and similar drills in their music lessons. Today, there’s a better way. Pianoforall lets you jump right in to discover what makes music fun, leaving you eager to learn more. In a simple but innovative approach, […]
There are two times you never want to just “eyeball” it: Conducting brain surgery and matching shades of paint for your walls. Whether you’re painting or repainting, make sure you’re never just “close enough” to the color you want. Not when the Nix Mini Color Sensor can scan and match any color perfectly. Small enough […]
