+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.

+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+% CIS-HARDENING(8)
+%
+% 2016
+
+# NAME
+
+cis-hardening - CIS Debian 9/10 Hardening
+
+# SYNOPSIS
+
+**hardening.sh** RUN_MODE [OPTIONS]
+
+# DESCRIPTION
+
+Modular Debian 9/10 security hardening scripts based on the CIS (https://www.cisecurity.org) recommendations.
+
+We use it at OVHcloud (https://www.ovhcloud.com) to harden our PCI-DSS infrastructure.
+
+# SCRIPTS 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 MODE
+
+`-h`, `--help`
+:   Display a friendly help message.
+
+`--apply`
+:   Apply hardening for enabled scripts.
+    Beware that NO confirmation is asked whatsoever, which is why you're warmly
+    advised to use `--audit` before, which can be regarded as a dry-run mode.
+
+`--audit`
+:   Audit configuration for enabled scripts.
+    No modification will be made on the system, we'll only report on your system
+    compliance for each script.
+
+`--audit-all`
+:   Same as `--audit`, but for *all* scripts, even disabled ones.
+    This is a good way to peek at your compliance level if all scripts were enabled,
+    and might be a good starting point.
+
+`--audit-all-enable-passed`
+:   Same as `--audit-all`, but in addition, will *modify* the individual scripts
+    configurations to enable those which passed for your system.
+    This is an easy way to enable scripts for which you're already compliant.
+    However, please always review each activated script afterwards, this option
+    should only be regarded as a way to kickstart a configuration from scratch.
+    Don't run this if you have already customized the scripts enable/disable
+    configurations, obviously.
+
+`--create-config-files-only`
+:   Create the config files in etc/conf.d
+    Must be run as root, before running the audit with user secaudit
+
+`-set-hardening-level=level`
+:   Modifies the configuration to enable/disable tests given an hardening level,
+    between 1 to 5. Don't run this if you have already customized the scripts
+    enable/disable configurations.
+    1: very basic policy, failure to pass tests at this level indicates severe
+        misconfiguration of the machine that can have a huge security impact
+    2: basic policy, some good practice rules that, once applied, shouldn't
+        break anything on most systems
+    3: best practices policy, passing all tests might need some configuration
+        modifications (such as specific partitioning, etc.)
+    4: high security policy, passing all tests might be time-consuming and
+        require high adaptation of your workflow
+    5: placebo, policy rules that might be very difficult to apply and maintain,
+        with questionable security benefits
+
+`--allow-service=service`
+:   Use with `--set-hardening-level`.
+    Modifies the policy to allow a certain kind of services on the machine, such
+    as http, mail, etc. Can be specified multiple times to allow multiple services.
+    Use --allow-service-list to get a list of supported services.
+
+# OPTIONS
+
+`--allow-service-list`
+:   Get a list of supported service.
+
+  
+`--only test-number`
+:    Modifies the RUN_MODE to only work on the test_number script.
+    Can be specified multiple times to work only on several scripts.
+    The test number is the numbered prefix of the script,
+    i.e. the test number of 1.2_script_name.sh is 1.2.
+
+`--sudo`
+:   This option lets you audit your system as a normal user, but allows sudo
+    escalation to gain read-only access to root files. Note that you need to
+    provide a sudoers file with NOPASSWD option in /etc/sudoers.d/ because
+    the -n option instructs sudo not to prompt for a password.
+    Finally note that `--sudo` mode only works for audit mode.
+
+`--batch`
+:   While performing system audit, this option sets LOGLEVEL to 'ok' and
+    captures all output to print only one line once the check is done, formatted like :
+    OK|KO OK|KO|WARN{subcheck results} [OK|KO|WARN{...}]
