# Contributing to The Bastion
|
||||
|
||||
This project accepts contributions. In order to contribute, you should
|
||||
pay attention to a few things:
|
||||
|
||||
1. your code must follow the The Bastion design choices, see DESIGN.md
|
||||
2. your code must follow the coding style rules
|
||||
3. your code must be added to the unit and/or integration tests where applicable
|
||||
4. your code must be documented
|
||||
5. your work must be signed (see below)
|
||||
6. you may contribute through GitHub Pull Requests
|
||||
|
||||
# Coding and documentation Style for source code
|
||||
|
||||
- All languages
|
||||
- Code must be indented with 4-spaces, no tabs. Vim modelines are present
|
||||
in all source files, so if you use vim, you should be good to go
|
||||
- Perl
|
||||
- Code must be tidy (see `bin/dev/perl-tidy.sh`)
|
||||
- Code must not raise any perlcritic warning (see `bin/dev/perl-critic.sh`)
|
||||
- One must refrain using any non-core Perl module (check `corelist`)
|
||||
- If not possible, the module should be packaged at least under Debian,
|
||||
all supported versions, and available at least in trusted third party
|
||||
repositories on other supported OSes. No `cpan install`.
|
||||
- POSIX shell and Bash
|
||||
- Code must not raise any shellcheck warning (see `bin/dev/shell-check.sh`)
|
||||
|
||||
# Submitting Modifications
|
||||
|
||||
The contributions should be submitted through Github Pull Requests
|
||||
and follow the DCO which is defined below.
|
||||
|
||||
# Licensing for new files
|
||||
|
||||
The Bastion is licensed under the Apache License 2.0. Anything
|
||||
contributed to The Bastion must be released under this license.
|
||||
|
||||
When introducing a new file into the project, please make sure it has a
|
||||
copyright header making clear under which license it's being released.
|
||||
|
||||
# Developer Certificate of Origin (DCO)
|
||||
|
||||
To improve tracking of contributions to this project we will use a
|
||||
process modeled on the modified DCO 1.1 and use a "sign-off" procedure
|
||||
on patches that are being emailed around or contributed in any other
|
||||
way.
|
||||
|
||||
The sign-off is a simple line at the end of the explanation for the
|
||||
patch, which certifies that you wrote it or otherwise have the right
|
||||
to pass it on as an open-source patch. The rules are pretty simple,
|
||||
if you can certify the below:
|
||||
|
||||
By making a contribution to this project, I certify that:
|
||||
|
||||
(a) The contribution was created in whole or in part by me and I have
|
||||
the right to submit it under the open source license indicated in
|
||||
the file; or
|
||||
|
||||
(b) The contribution is based upon previous work that, to the best of
|
||||
my knowledge, is covered under an appropriate open source License
|
||||
and I have the right under that license to submit that work with
|
||||
modifications, whether created in whole or in part by me, under
|
||||
the same open source license (unless I am permitted to submit
|
||||
under a different license), as indicated in the file; or
|
||||
|
||||
(c) The contribution was provided directly to me by some other person
|
||||
who certified (a), (b) or (c) and I have not modified it.
|
||||
|
||||
(d) The contribution is made free of any other party's intellectual
|
||||
property claims or rights.
|
||||
|
||||
(e) I understand and agree that this project and the contribution are
|
||||
public and that a record of the contribution (including all
|
||||
personal information I submit with it, including my sign-off) is
|
||||
maintained indefinitely and may be redistributed consistent with
|
||||
this project or the open source license(s) involved.
|
||||
|
||||
|
||||
then you just add a line saying
|
||||
|
||||
Signed-off-by: Random J Developer <random@example.org>
|
||||
|
||||
using your real name (sorry, no pseudonyms or anonymous contributions.)

# The Bastion design choices
|
||||
|
||||
This document aims to summarize a few design choices that have been made
|
||||
on this project, that dictate how features are implemented.
|
||||
|
||||
## Use the well trusted and existing UNIX building blocks, don't recode them
|
||||
|
||||
The Bastion heavily relies on well known and trusted system blocks to work.
|
||||
All the SSH part is completely handled by OpenSSH server and client programs.
|
||||
The MFA mechanism also heavily relies on PAM.
|
||||
|
||||
## The OS as a safety net for buggy or exploitable code
|
||||
|
||||
A bastion functional user is always mapped to an actual operating system user.
|
||||
Same goes for bastion groups: they're mapped to actual OS groups.
|
||||
This is also true for group roles: gatekeeper, owner and aclkeeper roles are
|
||||
mapped to system groups.
|
||||
|
||||
Private keys of an account are only readable by the corresponding operating
|
||||
system user, and same goes for the group private keys. This way, even if the
|
||||
code is tricked to allow access when it shouldn't have (flawed logic or bug),
|
||||
then the OS will still deny reading the key file.
|
||||
|
||||
This concept has been explained in the ([https://www.ovh.com/blog/the-bastion-part-3-security-at-the-core/](Blog Post #3 - Security at the Core))
|
||||
|
||||
## Zero trust between portions of code running at different permission levels
|
||||
|
||||
Most of The Bastion code is running under the unprivileged system user
|
||||
corresponding to the actual user of the bastion. When some code needs to
|
||||
run with privileges, for example to be able to create an account, a first
|
||||
portion of the code checks for the validity of the request first, under the
|
||||
same privileges than the user, this is called `a plugin`.
|
||||
To actually create the system user, `sudo` is used to run just a specific
|
||||
portion of the code. Such portions of code are named `helpers`, and always
|
||||
run under perl tainted mode.
|
||||
|
||||
Helpers communicate back their result using JSON, which is then read from
|
||||
the plugin (the unprivileged portion of code), and parsed.
|
||||
|
||||
This concept has been explained in the ([https://www.ovh.com/blog/the-bastion-part-3-security-at-the-core/](Blog Post #3 - Security at the Core))

|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.

||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity

2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
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
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
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
|
||||
of your accepting any such warranty or additional liability.

Bastions are a cluster of machines used as the unique entry point by operational teams (such as sysadmins, developers, database admins, ...) to securely connect to devices (servers, virtual machines, cloud instances, network equipment, ...), usually using `ssh`.
|
||||
|
||||
Bastions provides mechanisms for authentication, authorization, traceability and auditability for the whole infrastructure.
|
||||

## Installing, upgrading, using The Bastion
|
||||
|
||||
Please see the online documentation ([https://ovh.github.io/the-bastion](https://ovh.github.io/the-bastion)), or the corresponding text-based documentation which can be found in the `doc/` folder.
|
||||
|
||||
## TL;DR
|
||||
|
||||
### Testing it with Docker
|
||||
|
||||
Let's build the docker image and run it
|
||||
|
||||
docker build -f docker/Dockerfile.debian10 -t bastion:debian10 .
|
||||
docker run -d -p 22 --name bastiontest bastion:debian10
|
||||
|
||||
Configure the first administrator account (get your public SSH key ready)
|
||||
|
||||
docker exec -it bastiontest /opt/bastion/bin/admin/setup-first-admin-account.sh poweruser auto
|
||||
|
||||
We're now up and running with the default configuration! Let's setup a handy bastion alias, and test the `info` command:
|
||||
|
||||
PORT=$(docker port bastiontest | cut -d: -f2)
|
||||
alias bastion="ssh poweruser@127.0.0.1 -tp $PORT -- "
|
||||
bastion --osh info
|
||||
|
||||
It should greet you as being a bastion admin, which means you have access to all commands. Let's enter interactive mode:
|
||||
|
||||
bastion -i
|
||||
|
||||
This is useful to call several `--osh` plugins in a row. Now we can ask for help to see all plugins:
|
||||
|
||||
$> help
|
||||
|
||||
If you have a remote machine you want to try to connect to through the bastion, fetch your egress key:
|
||||
|
||||
$> selfListEgressKeys
|
||||
|
||||
Copy this public key to the remote machine's `authorized_keys` under the `.ssh/` folder of the account you want to connect to, then:
|
||||
|
||||
$> selfAddPersonalAccess --host <remote_host> --user <remote_account_name> --port-any
|
||||
$> ssh <remote_account_name>@<remote_host>
|
||||
|
||||
Note that you can connect directly without using interactive mode, with:
|
||||
|
||||
bastion <remote_account_name>@<remote_machine_host_or_ip>
|
||||
|
||||
That's it! Additional documentation is available under the `doc/` folder and online ([https://ovh.github.io/the-bastion](https://ovh.github.io/the-bastion)).
|
||||
Be sure to check the help of the bastion (`bastion --help`) and the help of each osh plugin (`bastion --osh command --help`)
|
||||
Also don't forget to customize your `bastion.conf` file, which can be found in `/etc/bastion/bastion.conf` (for Linux)
|
||||
|
||||
## Compatibility
|
||||
|
||||
Linux distros below are tested with each release, but as this is a security product, you are *warmly* advised to run it on the latest up-to-date stable version of your favorite OS:
|
||||
|
||||
- Debian 10 (Buster), 9 (Stretch), 8 (Jessie)
|
||||
- RHEL/CentOS 8, 7
|
||||
- Ubuntu LTS 20.04, 18.04, 16.04, 14.04*
|
||||
- OpenSUSE Leap 15.1*, 15*
|
||||
|
||||
*: Note that these versions have no MFA support.
|
||||
Any other so-called "modern" Linux version are not tested with each release, but should work with no or minor adjustments.
|
||||
|
||||
The code is also known to work correctly under:
|
||||
|
||||
- FreeBSD 10+ / HardenedBSD [no MFA support]
|
||||
|
||||
Other BSD variants partially work but are unsupported and discouraged as they have a severe limitation over the maximum number of supplementary groups (causing problems for group membership and restricted commands checks), no filesystem-level ACL support and missing MFA:
|
||||
|
||||
- OpenBSD 5.4+
|
||||
- NetBSD 7+
|
||||
|
||||
## Reliability
|
||||
|
||||
When hell is breaking loose on all your infrastructures and/or your network, bastions still need to be the last component standing because you need them to access the rest of your infrastructure... to be able to actually fix the problem. Hence reliability is key.
|
||||
|
||||
* The KISS principle is used where possible for design and code: less complicated code means more auditability and less bugs
|
||||
* Only a few well-known libraries are used, less third party code means a tinier attack surface
|
||||
* The bastion is engineered to be self-sufficient: less dependencies such as databases, other daemons, or other machines, statistically means less downtime
|
||||
* High availability can be setup so that multiple bastion instances form a cluster of several instances, with any instance usable at all times (active/active scheme)
|
||||
|
||||
# Code quality
|
||||
|
||||
* The code is ran under `perltidy`
|
||||
* The code is also ran under `perlcritic`
|
||||
* Functional tests are used before every release
|
||||
|
||||
## Security at the core
|
||||
|
||||
Even with the most conservative, precautionous and paranoid coding process, code has bugs, so it shouldn't be trusted blindly. Hence the bastion doesn't trust its own code. It leverages the operating system security primitives to get additional security, as seen below.
|
||||
|
||||
- Uses the well-known and trusted UNIX Discretionary Access Control:
|
||||
- Bastion users are mapped to actual system users
|
||||
- Bastion groups are mapped to actual system groups
|
||||
- All the code is constantly checking rights before allowing any action
|
||||
- UNIX DAC is used as a safety belt to prevent an action from succeeding even if the code is tricked into allowing it
|
||||
|
||||
- The bastion main script is declared as the bastion user's system shell:
|
||||
- No user has real (`bash`-like) shell access on the system
|
||||
- All code is ran under the unprivileged user's system account rights
|
||||
- Even if a user could escape to a real shell, he wouldn't be able to connect to machines he doesn't have access to, because he doesn't have filesystem-level read access to the SSH keys
|
||||
|
||||
- The code is modular
|
||||
- The main code mainly checks rights, logs actions, and enable `ssh` access to other machines
|
||||
- All side commands, called *plugins*, are in modules separated from the main code
|
||||
- The modules can either be *open* or *restricted*
|
||||
- Only accounts that have been specifically granted on a need-to-use basis can run a specific restricted plugin
|
||||
- This is checked by the code, and also enforced by UNIX DAC (the plugin is only readable and executable by the system group specific to the plugin)
|
||||
|
||||
- All the code needing extended system privileges is separated from the main code, in modules called *helpers*
|
||||
- Helpers are run exclusively under `sudo`
|
||||
- The `sudoers` configuration is attached to a system group specific to the command, which is granted to accounts on a need-to-use basis
|
||||
- The helpers are only readable and executable by the system group specific to the command
|
||||
- The helpers path and some of their immutable parameters are hardcoded in the `sudoers` configuration
|
||||
- Perl tainted mode (`-T`) is used for all code running under `sudo`, preventing any user-input to interfere with the logic, by halting execution immediately
|
||||
- Code running under `sudo` doesn't trust its caller and re-checks every input
|
||||
- Communication between unprivileged and privileged-code are done using JSON
|
||||
|
||||
## Auditability
|
||||
|
||||
- Bastion administrators must use the bastion's logic to connect to itself to administer it (or better, use another bastion to do so), this ensures auditability in all cases
|
||||
* Every access and action (wether allowed or denied) is logged with:
|
||||
* `syslog`, which should also be sent to a remote syslog server to ensure even bastion administrators can't tamper their tracks, and/or
|
||||
* local `sqlite3` databases for easy searching
|
||||
* This code is used in production in several PCI-DSS, ISO 27001, SOC1 and SOC2 certified environments

Add an IP or IP block to a group's servers list
|
||||
|
||||
Usage: --osh SCRIPT_NAME --group GROUP [OPTIONS]
|
||||
|
||||
--group GROUP Specify which group this machine should be added to (it should have the public group key of course)
|
||||
--host HOST|IP|NET/CIDR Host(s) to add access to, either a HOST which will be resolved to an IP immediately, or an IP,
|
||||
or a whole network using the NET/CIDR notation
|
||||
--user USER Specify which remote user should be allowed (root, run, etc...)
|
||||
--user-any Allow any remote user (the remote user should still have the public group key in all cases)
|
||||
--port PORT Only allow access to this port (e.g. 22)
|
||||
--port-any Allow access to any port
|
||||
--scpup Allow SCP upload, you--bastion-->server (omit --user in this case)
|
||||
--scpdown Allow SCP download, you<--bastion--server (omit --user in this case)
|
||||
--force Don't try the ssh connection, just add the host to the group blindly
|
||||
--force-key FINGERPRINT Only use the key with the specified fingerprint to connect to the server (cf groupInfo)
|
||||
--ttl SECONDS|DURATION Specify a number of seconds (or a duration string, such as "1d7h8m") after which the access will automatically expire
|
||||
--comment '"ANY TEXT'" Add a comment alongside this server
|
||||
|
||||
Examples::
|
||||
|
||||
--osh SCRIPT_NAME --group grp1 --host 203.0.113.0/24 --user-any --port-any --force --comment '"a whole network"'
|
