+# CIS Debian 7 Hardening
+
+Modular Debian 7 security hardening scripts based on [cisecurity.org](cisecurity.org)
+recommendations. We use it at [OVH](https://ovh.com) to harden our PCI-DSS infrastructure.
+
+```console
+$ bin/hardening.sh --audit
+TODO: some eye catchy output
+```
+
+## Quickstart
+
+```console
+$ git clone https://github.com/ovh/debian-cis.git && debian-cis
+$ some-example-command
+```
+
+## Usage
+
+### Configuration
+
+Hardening scripts are in ``bin/hardening``. Each script has a corresponding
+configuration file in ``etc/conf.d/[script_name].cfg``.
+
+Each hardening script can be individually enabled from its configuration file.
+For example, this is the default configuration file for ``disable_system_accounts``:
+
+```
+# Configuration for script of same name
+status=disabled
+# Put here your exceptions concerning admin accounts shells separated by spaces
+EXCEPTIONS=""
+```
+
+``status`` parameter may take 3 values:
+- ``disabled`` (do nothing): The script will not run.
+- ``audit`` (RO): The script will check if any change *should* be applied.
+- ``enabled`` (RW): The script will check if any change should be done and automatically apply what it can.
+
+Global configuration is in ``etc/hardening.cfg``. This file controls the log level
+as well as the backup directory. Whenever a script is instructed to edit a file, it
+will create a timestamped backup in this directory.
+
+### Run aka "Harden your distro"
+
+To run the checks and apply the fixes, run ``bin/hardening.sh``.
+
+This command has 2 main operation modes:
+- ``--audit``: Audit your system with all enabled and audit mode scripts
+- ``--apply``: Audit your system with all enabled and audit mode scripts and apply changes for enabled scripts
+
+Additionally, ``--audit-all`` can be used to force running all auditing scripts,
+including disabled ones. this will *not* change the system.
+
+``--audit-all-enable-passed`` can be used as a quick way to kickstart your
+configuration. It will run all scripts in audit mode. If a script passes,
+it will automatically be enabled for future runs. Do NOT use this option
+if you have already started to customize your configuration.
