auditd Cookbook

A simple cookbook to install auditd and provided rulesets. Rulesets
included in the OS auditd/audit package as examples are based on 4
established standards:

• Controlled Access Protection Profile (CAPP)
• Labeled Security Protection Profile (LSPP)
• National Industrial Security Program Operating Manual (NISPOM)
• Security Technical Implementation Guides

The OS package provides the client side tools for working with the
linux kernel audit framework.

Requirements

Linux : any distribution in theory, but only Ubuntu and RHEL 6 have been tested.

Attributes

• node['auditd']['ruleset'] - ruleset to use, either "default" (the default if unset) or one of the provided examples
• node['auditd']['backlog'] - backlog size, default is 320 should be larger for busy systems

Usage

If you're using one of the default rulesets set the correct attribute
based on the ruleset desired, one of:

• "capp" : Controlled Access Protection Profile
• "lspp" : Labeled Security Protection Profile
• "nispom" : National Industrial Security Program Operating Manual (NISPOM)
• "stig" : Security Technical Implementation Guides
• "cis" : Center for Internet Security auditd recommendations

And include recipe[auditd::rules] in your run list. You can also set
the attribute node['auditd']['ruleset'] to the name of a custom rule
template to be used instead of one of the default rules.

If you are using the recipe from a wrapper cookbook, include the
default recipe recipe[auditd] to setup the service and use the
auditd_ruleset resource to place your rule template of choice.

If you are not satisfied with any of the provided templates, you can
specify the cookbook attribute in auditd_ruleset to use your own
set of rules. In this case, do not include recipe[auditd::rules].

TODO

Ideally the auditd_ruleset resource could make use of a data bag
search to build the data driven ruleset

Make builtins an array attribute to allow user updates without
cookbook release.
