Snort 2.8.6.1 isn't EOL yet!

This mornings post (and the previous week's posts) were in error.  Snort 2.8.6.1's EOL date is 90 days past the release of 2.9.1.

Snort 2.9.1 was released on August 23rd.  That places our 90 day window at November 23rd.  We apologize for any panic and inconvenience this may have caused.

We do highly recommend you take the next month to upgrade to Snort 2.9.1.2.  It should be our last release (unless something catastrophic comes up) until Snort 2.9.2.

Again, apologies.

The VRT is looking for more good test environments.

Over the years we have developed a large rule test environment, both internally at Sourcefire and externally with test sensors and customer networks. We are looking to expand this trusted group of Snort rule contributors. When we have a rule we'd like to deploy "in the wild" we will send these rules into these environments. We're looking to expand this group another 20 or so.

This group needs to have a large variety of things on the network.  Servers, clients, Windows, Macs, Linux, malware, the works. .EDU, .MIL, .GOV, .COM. These need to be large environments with lots of diversity. The rules we send to you will be governed under the VRT license, and may or may not make it into the official VRT ruleset.

You will be required to sign a NDA with us in order to be a part of this group, because in addition, as an added benefit to being a member of this group, we’ll be giving you access to our blacklist IP ruleset. This ruleset used by the IP reputation preprocessor currently contains about 3 Million IPs, and will change by approximately 20,000 to 100,000 per day.

Information we'd need back from you:

  • Performance of the rule.
  • Detection of the rule (Is it false positive prone? Is it useful to you?)
  • The ability to grab full session packet captures of traffic, if needed.
  • The ability to provide the packet captures to us, of course, under the NDA.


As a reward, we will receive a free VRT subscription, Tshirts, calendars, and of course, access to the blacklist IP feed.

If you are interested, please respond back to me, personally, at jesler@sourcefire.com. Please do not respond to the list, to preserve your anonymity.

VRT Rule release for 10/18/2011

A Comparison of 3 Popular Snort GUIs

James Lay, an outstanding Snort Community Member, sent me this great comparison of three popular Snort GUIs:

  • BASE 1.4.5
  • Snorby 2.3.9
  • SQueRT 0.9.2
I've posted it on http://snort.org/docs as well, but for those of you that would like a direct link:

https://www.snort.org/documents/29

I'd like to take the time to thank James for the time he took to set all three of these up and compare the two.

If anyone would like to add another Snort GUI that you use to this matrix, please send me the name of the product, version, and the points as laid out in the document.  If you'd like to add some fields, that'd be fine too.

Snort 2.9.1.1 is available immediately from the Snort download site.

To make installation easier for our users, you simply need to compile Snort with

We'll be working with our community documentation writers in order to update the documentation to reflect this information.

These changes are included in the etc/ directory of the VRT tarball for subscribers. If you are a registered Snort user, you may make the changes manually to your Snort.conf as seen above, or you can download the 2.9.1.1 snort.conf here.
