mklauber-aide

Build Status:

mklauber/aide is a puppet module for managing Aide (Advanced Intrustion Detection Environment). It allows you to define Rules and File/folder watches via defined types. Refer to the Aide manual for details about Aide configuration options.

Examples

Watch permissions of all files on filesystem

The simplest use of mklauber/aide is to place a watch on the root directory, as follows.

aide::watch { 'example':
  path  => '/',
  rules => 'p'
}

This example adds the line / R which watches the permissions of all files on the operating system. Obviously, this is a simplistic, non useful solution.

Watch permissions and md5sums of all files in /etc

aide::watch { 'example':
  path  => '/etc',
  rules => 'p+md5'
}

This example adds the line /etc p+md5 which watches /etc with both permissions and md5sums. This could also be implemented as follows.

aide::watch { 'example':
  path  => '/etc',
  rules => ['p', 'md5']
}

Create a common rule for watching multiple directories

Sometimes you wish to use the same rule to watch multiple directories, and in keeping with the Don't Repeat Yourself(DRY) viewpoint, we should create a common name for the rule. This can be done via the aide::rule stanza.

aide::rule { 'MyRule':
  name  => 'MyRule',
  rules => ['p', 'md5']
}
aide::watch { '/etc':
  path  => '/etc',
  rules => 'MyRule'
}
aide::watch { 'otherApp':
  path  => '/path/to/other/config/dir',
  rules => 'MyRule'
}

Here we are defining a rule in called MyRule which will add the line MyRule = p+md5. The next two stanzas can reference that rule. They will show up as /etc MyRule and /path/to/other/config/dir MyRule.
