|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||

|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
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.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
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
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason

# NAME
|
||||
|
||||
cis-hardening - CIS Debian 10/11/12 Hardening
|
||||
|
||||
# SYNOPSIS
|
||||
|
||||
**hardening.sh** RUN_MODE [OPTIONS]
|
||||
|
||||
# DESCRIPTION
|
||||
|
||||
Modular Debian 10/11/12 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.
|
||||
|
||||
`--set-log-level=level`
|
||||
: This option sets LOGLEVEL, you can choose : info, warning, error, ok, debug.
|
||||
Default value is : info
|
||||
|
||||
`--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{...}]
|
||||
|
||||
`--allow-unsupported-distribution`
|
||||
Must be specified manually in the command line to allow the run on non compatible
|
||||
version or distribution. If you want to mute the warning change the LOGLEVEL
|
||||
in /etc/hardening.cfg

|

Some tests ar labelled with a disclaimer warning that we only test on a blank host

and that we will not test the apply function. It's because the check is very basic

(like a package install) and that a test on it is not really necessary.

Furthermore, some tests are disabled on docker because there not pertinent (kernel

## :art: Coding style
|
||||
### Shellcheck
|
||||
|
||||
We use [Shellcheck](https://github.com/koalaman/shellcheck) to check the
|
||||
correctness of the scripts and to respect best practices.
|
||||
It can be used directly with the docker environnment to check all scripts
|
||||
compliancy. By default it runs on every `.sh` it founds.
|
||||
|
||||
```console
|
||||
$ ./shellcheck/launch_shellcheck.sh [name of script...]
|
||||
```
|
||||
|
||||
### Shellfmt
|
||||
|
||||
We use [Shellfmt](https://github.com/mvdan/sh) to check the styling and to keep a
|
||||
consistent style in every script.
|
||||
Identically to shellcheck, it can be run through a script with the following:
|
||||
|
||||
```console
|
||||
$ ./shellfmt/launch_shellfmt.sh
|
||||
```
|
||||
It will automatically fix any styling problem on every script.

This project is a set of tools. They are meant to help the system administrator

built a secure environment. While we use it at OVHcloud to harden our PCI-DSS compliant

|

|
||||
A word about numbering, implementation and sustainability over time of this repository:
|
||||
This project is born with the Debian 7 distribution in 2016. Over time, CIS Benchmark PDF
|
||||
has evolved, changing it's numbering, deleting obsolete checks.
|
||||
In order to keep retro-compatiblity with the last maintained Debian, the numbering
|
||||
has not been changed along with the PDF, because the configuration scripts are named after it.
|
||||
Changing the numbering might break automation for admins using it for years, and handling
|
||||
this issue without breaking anything would require a huge refactoring.
|
||||
As a consequence, please do not worry about numbering, the checks are there,
|
||||
but the numbering accross PDFs might differ.
|
||||
Please also note that all the check inside CIS Benchmark PDF might not be implemented
|
||||
in this set of scripts.
|
||||
We did choose the most relevant to us at OVHcloud, do not hesitate to make a
|
||||
Pull Request in order to add the missing script you might find relevant for you.
