# Juju charm-helpers hardening library
## Description
This library provides multiple implementations of system and application
hardening that conform to the standards of http://hardening.io/.
Current implementations include:
* OS
* SSH
* MySQL
* Apache
## Requirements
* Juju Charms
## Usage
1. Synchronise this library into your charm and add the harden() decorator
(from contrib.hardening.harden) to any functions or methods you want to use
to trigger hardening of your application/system.
2. Add a config option called 'harden' to your charm config.yaml and set it to
a space-delimited list of hardening modules you want to run e.g. "os ssh"
3. Override any config defaults (contrib.hardening.defaults) by adding a file
called hardening.yaml to your charm root containing the name(s) of the
modules whose settings you want override at root level and then any settings
with overrides e.g.
os:
general:
desktop_enable: True
4. Now just run your charm as usual and hardening will be applied each time the
hook runs.
