What is Snort?

Snort is the foremost Open Source Intrusion Prevention System (IPS) in the
world. Snort IPS uses a series of rules that help define malicious network
activity and uses those rules to find packets that match against them and
generates alerts for users.

Snort can be deployed inline to stop these packets, as well. Snort has three
primary uses: As a packet sniffer like tcpdump, as a packet logger — which is
useful for network traffic debugging, or it can be used as a full-blown network
intrusion prevention system. Snort can be downloaded and configured for personal
and business use alike.

What are my options for buying and using Snort?

Once downloaded and configured, Snort rules are distributed in two sets: The
“Community Ruleset” and the “Snort Subscriber Ruleset.”

The Snort Subscriber Ruleset is developed, tested, and approved by Cisco Talos.
Subscribers to the Snort Subscriber Ruleset will receive the ruleset in
real-time as they are released to Cisco customers. You can download the rules
and deploy them in your network through the Snort.org website. The Community
Ruleset is developed by the Snort community and QAed by Cisco Talos. It is
freely available to all users.

For more information about Snort Subscriber Rulesets available for purchase,
please visit the Snort product page.

Get Started
Step 1

DOWNLOAD AND INSTALL THE SOURCE CODE

If this is your first time installing Snort, please review the dependencies
list.

https://github.com/snort3/snort3/archive/refs/tags/3.1.53..0.tar.gz

You can also get the code with:

git clone https://github.com/snort3/snort3.git

There are separate extras packages for cmake that provide additional features
and demonstrate how to build plugins. The source for extras is in the
snort3_extra.git repo.

Step 2

SIGN UP AND GET YOUR OINKCODE - A UNIQUE IDENTIFIER THAT MUST BE ENTERED INTO
YOUR SNORT INSTANCE THAT WILL AUTOMATICALLY PULL IN SNORT RULES. ALL USERS HAVE
ACCESS TO THE REGISTERED RULE SET. IN ORDER TO GET THE LATEST DETECTIONS
(SUBSCRIBER RULE SET) YOU CAN UPGRADE YOUR SUBSCRIPTION AT ANY TIME.
