Description

Installs the SNORT IDS daemon. On Debian/Ubuntu systems, the packages
from apt are used. On RHEL and Fedora systems, the packages are
retrieved directly from the SNORT project site.

Requirements

Platform

• Ubuntu 10.04+
• RHEL/CentOS, 7.0 and higher only.
• Fedora 20+

May work on other platforms in the Debian and RHEL families with or
without modification.

Cookbooks

No other cookbooks are dependencies, however to use one of the
database backends, the appropriate cookbook should be used. For
example, Opscode cookbooks:

• mysql
• postgresql

Attributes

See attributes/default.rb for default values.

• node['snort']['home_net'] - Address range to use for preseeding HOME_NET.
• node['snort']['database'] - The database backend to use. Only applicable on Debian/Ubuntu systems. Default none. MySQL and PostgreSQL are usable. The default recipe will install the SNORT package for the appropriate database backend. You'll need to make sure that the database server is set up in some way such that SNORT can connect to it. This cookbook does not yet support automatic configuration.
• node['snort']['rpm']['daq_version'] - The full version string of the daq package to install, e.g. "2.0.0-1.fc17".
• node['snort']['rpm']['daq_checksum'] - The SHA256 checksum of the daq rpm.
• node['snort']['rpm']['version'] - The full version string of the snort package to install, e.g., "2.9.4-1.f17".
• node['snort']['rpm']['checksum'] - The SHA256 checksum of the snort rpm.

NOTE Upstream, the SNORT project has deprecated the database
output
as of version 2.9.3.

Usage

Include recipe[snort] in a run list to have the system get SNORT
installed. This performs a baseline installation and preseeds the
package. You should change the node['snort']['home_net'] attribute
to the appropriate network.

We recommend adding a template resource to the default recipe to
manage the /etc/snort/snort.conf file as a template. The default
file is good enough for now on Debian/Ubuntu.

On Ubuntu/Debian, the default rules package will be installed. You'll
need to download and install additional rules. Automatically updating
rules with oinkmaster is not yet supported. See future plans.

Future Plans

The following features are planned for a future release of this
cookbook. Contributions welcome.
- Source-based installation.
- Other platforms in general :).
