Description
An Ansible role to install, configure, and schedule AIDE.

Defining and Undefining aide.conf Variables
aide_macros:
define:
- name: "Give it a name"
variable: "Name_of_Variable"
value: "Value of the variable"
- name: "DBDIR var"
variable: "DBDIR"
value: "/var/lib/aide"
undefine:
- name: "Some var to undefine"
variable: "Name_of_Variable" #This would effectively undefine the variable we defined above
- name: "Undefining DBDIR var"
variable: "DBDIR"
Defining Rules/Groups, Selection paths, and Ignore/Negative Selection Paths
A YAML spec was built to handle all of these items in a relatively organized way.
Attributes available to a rule
aide_rules:
- name: "My first rule" #Required
rule: "FIPSR" #Required
comment: "Comment to put above this rule declaration" #Optional
attributes: [] #List made up of default rules or defined rules #Required except on special negative rule
paths: #Optional
- "/my/include/path/1" #Cannot start with '!' see Ignore/Negative Selection Paths
- "/my/include/path/2"
A Special Rule to handle Ignore/Negative Selection Paths is available
Add a rule to your aide_rules: definition with rule: negative
Here's an example, and you can also find an example in this Role's defaults/main.yml:
aide_rules:
- name: "My negative/ignore selections" #Required
rule: "negative" #Required
paths: #Required
- "/my/ignore/path/1"
- "/my/ignore/path/2"
Do not include an '!' in front of the paths, the template logic will automatically do this for you.
Scheduled Cron Aide Checks
The default is to setup an 'aide --check' in crontab. Should you wish to change this after already allowing this role to create the cron job, simply switch the variable aide_cron_schedule_check to False. This will remove the cron job from your system's crontab on the next playbook run. One caveat to be aware of is that the aide_cronjob_name variable must match what's currently in the crontab to be removed properly.
