Description

Installs and configures SNORT. 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, 12.04
  • RHEL/CentOS, 6.0 and higher only.
  • Fedora 17

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, see How to Contribute

Perform additional configuration of /etc/snort/snort.conf via template.

Oinkmaster automatic rules updates.

Source-based installation.

Other platforms in general :).
