IMPORTANT Rule Download Change

Today the Snort Web Team made a change to the way that Snort rules are downloaded from snort.org. Hopefully this will result in faster downloads for most people. The changes are highlighted below:We are changing the way we publish rules. In June 2010 we stopped offering rules in the "snortrules-snapshot-CURRENT" format. Instead, rules are released for specific versions of Snort. You will be

Smart Grids and the Importance of Smart Security Choices

I got a flyer in my mail a couple of days ago, telling me that my local utility company would be coming out soon to install a smart meter on my house. Like most customers, I didn't think too much about it, until the new meter was installed today. That's when my curiosity got the better of me - even though I arrived home after dark, I had to go take a look at the shiny new toy on the side of my

Emerging Threats Announces Call for Developers to Create New and Improved Rule Set

Emergingthreats - Mon, 06/21/2010 - 18:26

Emerging Threats today announces an open call for developers to assist in creating QA, load testing, backend management, and execute rule porting activities to support a professional-grade IDS ruleset for multiple IDS engines and platforms.

With this call for developers, Emerging Threats seeks to further engage and employ both existing and new members of the open-source security community.

The Suricata engine is a significant supported platform in addition to Snort and others. With advanced features such as a multi-threaded design and IP reputation, Suricata unlocks the potential for a more advanced ruleset than was previously possible.   

With the speed of malware creation rapidly advancing, Emerging Threats plans to create additional research and intelligence resources to advance rulesets and policies.  This will allow Emerging Threats to continue to provide individuals and companies with the advanced protection they have come to expect from the open community.

Emerging Threats is an open source community project that produces the fastest and most diverse IDS signature set available today, through the contributions and support of its community.

Successful candidates should be familiar with the snort rule syntax, Suricata, malware trends and command and control methods, vulnerability concepts, and a deep understanding of network protocols.

If you are interested in participating in this initiative, please contact Matt Jonkman at jonkman@emergingthreats.net or threats@emergingthreats.net

Defenders of the Faith

Quite recently, Tavis Ormandy released a 0-day vulnerability in a prominent piece of software. For this transgression, both he and his employer received a good deal of bad press. Sadly, very few in the professional security researcher crowd made enough noise about this, and to the contrary, one man in particular came down squarely against him. Thankfully however we still have Brad Spengler.
