# Contributor Guideline
|
||||
|
||||
This document provides an overview of how you can participate in improving this project or extending it. We are grateful for all your help: bug reports and fixes, code contributions, documentation or ideas. Feel free to join, we appreciate your support!!
|
||||
|
||||
## Communication
|
||||
|
||||
### GitHub repositories
|
||||
|
||||
Much of the issues, goals and ideas are tracked in the respective projects in GitHub. Please use this channel to report bugs and post ideas.
|
||||
|
||||
## git and GitHub
|
||||
|
||||
In order to contribute code please:
|
||||
|
||||
1. Fork the project on GitHub
|
||||
2. Clone the project
|
||||
3. Add changes (and tests)
|
||||
4. Commit and push
|
||||
5. Create a merge-request
|
||||
|
||||
To have your code merged, see the expectations listed below.
|
||||
|
||||
You can find a well-written guide [here](https://help.github.com/articles/fork-a-repo).
|
||||
|
||||
Please follow common commit best-practices. Be explicit, have a short summary, a well-written description and references. This is especially important for the merge-request.
|
||||
|
||||
Some great guidelines can be found [here](https://wiki.openstack.org/wiki/GitCommitMessages) and [here](http://robots.thoughtbot.com/5-useful-tips-for-a-better-commit-message).
|
||||
|
||||
|
||||
## Expectations
|
||||
|
||||
### Don't reinvent the wheel
|
||||
|
||||
This hardening project doesn't intend to reinvent the configuration stack for services. Aim to use official configuration projects first and provide hardening as a layer on top. The goal is remove the need for a user to configure all aspects of services and maintain security configuration. This way, the user can still configure a service using the interface provided by the official project.
|
||||
|
||||
* For Chef refer to the official [opscode community cookbooks](http://community.opscode.com/cookbooks).
|
||||
* For Puppet head to the [Puppet Forge](https://forge.puppetlabs.com/) and take a node of the Puppet supported modules.
|
||||
* For Ansible check the [Ansible Module Index](http://docs.ansible.com/list_of_all_modules.html)
|
||||
|
||||
These projects are generally hosted on GitHub as well.
|
||||
|
||||
In some cases, we in fact create the full rollout stack, but this is generally the exception ([os-hardening](https://github.com/TelekomLabs/chef-os-hardening), [nginx-hardening](https://github.com/TelekomLabs/chef-nginx-hardening)).
|
||||
|
||||
|
||||
### Be explicit
|
||||
|
||||
* Please avoid using nonsensical property and variable names.
|
||||
* Use self-describing attribute names for user configuration.
|
||||
* In case of failures, communicate what happened and why a failure occurs to the user. Make it easy to track the code or action that produced the error. Try to catch and handle errors if possible to provide improved failure messages.
|
||||
|
||||
|
||||
### Add tests
|
||||
|
||||
The security review of this project is done using integration tests.
|
||||
|
||||
Whenever you add a new security configuration, please start by writing a test that checks for this configuration. For example: If you want to set a new attribute in a configuration file, write a test that expects the value to be set first. Then implement your change.
|
||||
|
||||
You may add a new feature request by creating a test for whatever value you need.
|
||||
|
||||
All tests will be reviewed internally for their validity and overall project direction.
|
||||
|
||||
|
||||
### Document your code
|
||||
|
||||
As code is more often read than written, please provide documentation in all projects.
|
||||
|
||||
Adhere to the respective guidelines for documentation:
|
||||
|
||||
* Chef generally documents code based explicit readme files. For code documentation please use [yard-chef](https://github.com/rightscale/yard-chef)
|
||||
* [Puppet module documentation](http://docs.puppetlabs.com/puppet/latest/reference/modules_documentation.html)
|
||||
|
||||
|
||||
### Follow coding styles
|
||||
|
||||
We generally include test for coding guidelines:
|
||||
|
||||
* Chef follows [Foodcritic](http://acrmp.github.io/foodcritic/)
|
||||
* Puppet is checked with [puppet-lint](http://puppet-lint.com/checks/)
|
||||
* Ansible is checked by running the playbook with the syntax-check option, e.g. `ansible-playbook foo.yml --syntax-check`
|
||||
|
||||
Remember: Code is generally read much more often than written.
|
||||
|
||||
### Use Markdown
|
||||
|
||||
Wherever possible, please refrain from any other formats and stick to simple markdown.

# devsec.os_hardening
|
||||
|
||||
|
||||
|
||||
|
||||
## Looking for the old ansible-os-hardening role?
|
||||
|
||||
This role is now part of the hardening-collection. You can find the old role in the branch `legacy`.
|
||||
|
||||
## Description
|
||||
|
||||
This role provides numerous security-related configurations, providing all-round base protection. It is intended to be compliant with the [DevSec Linux Baseline](https://github.com/dev-sec/linux-baseline).
|
||||
|
||||
It configures:
|
||||
|
||||
* Remove unused yum repositories and enable GPG key-checking
|
||||
* Remove packages with known issues
|
||||
* Configures pam for strong password checks
|
||||
* Installs and configures auditd
|
||||
* Disable core dumps via soft limits
|
||||
* sets a restrictive umask
|
||||
* Configures execute permissions of files in system paths
|
||||
* Hardens access to shadow and passwd files
|
||||
* Disables unused filesystems
|
||||
* Disables rhosts
|
||||
* Configures secure ttys
|
||||
* Configures kernel parameters via sysctl
|
||||
* Enables selinux on EL-based systems
|
||||
* Remove SUIDs and GUIDs
|
||||
* Configures login and passwords of system accounts
|
||||
|
||||
It will not:
|
||||
|
||||
* Update system packages
|
||||
* Install security patches
|
||||
|
||||
## Requirements
|
||||
|
||||
* Ansible 2.9.0
|
||||
|
||||
## Known Limitations
|
||||
|
||||
### Docker support
|
||||
|
||||
If you're using Docker / Kubernetes+Docker you'll need to override the ipv4 ip forward sysctl setting.
|
||||
|
||||
```yaml
|
||||
- hosts: localhost
|
||||
collections:
|
||||
- devsec.hardening
|
||||
roles:
|
||||
- devsec.os_hardening
|
||||
vars:
|
||||
sysctl_overwrite:
|
||||
# Enable IPv4 traffic forwarding.
|
||||
net.ipv4.ip_forward: 1
|
||||
```
|
||||
|
||||
### sysctl - vm.mmap_rnd_bits
|
||||
|
||||
We are setting this sysctl to a default of `32`, some systems only support smaller values and this will generate an error. Unfortunately we cannot determine the correct applicable maximum. If you encounter this error you have to override this sysctl in your playbook.
|
||||
|
||||
```yaml
|
||||
- hosts: localhost
|
||||
collections:
|
||||
- devsec.hardening
|
||||
roles:
|
||||
- devsec.os_hardening
|
||||
vars:
|
||||
sysctl_overwrite:
|
||||
vm.mmap_rnd_bits: 16
|
||||
```
|
||||
|
||||
### Testing with inspec
|
||||
|
||||
If you're using inspec to test your machines after applying this role, please make sure to add the connecting user to the `os_ignore_users`-variable.
|
||||
Otherwise inspec will fail. For more information, see [issue #124](https://github.com/dev-sec/ansible-os-hardening/issues/124).
|
||||
|
||||
|
||||
We know that this is the case on Raspberry Pi.

## Packages
|
||||
|
||||
We remove the following packages:
|
||||
|
||||
* xinetd ([NSA](https://apps.nsa.gov/iaarchive/library/ia-guidance/security-configuration/operating-systems/guide-to-the-secure-configuration-of-red-hat-enterprise.cfm), Chapter 3.2.1)
|
||||
* inetd ([NSA](https://apps.nsa.gov/iaarchive/library/ia-guidance/security-configuration/operating-systems/guide-to-the-secure-configuration-of-red-hat-enterprise.cfm), Chapter 3.2.1)
|
||||
* tftp-server ([NSA](https://apps.nsa.gov/iaarchive/library/ia-guidance/security-configuration/operating-systems/guide-to-the-secure-configuration-of-red-hat-enterprise.cfm), Chapter 3.2.5)
|
||||
* ypserv ([NSA](https://apps.nsa.gov/iaarchive/library/ia-guidance/security-configuration/operating-systems/guide-to-the-secure-configuration-of-red-hat-enterprise.cfm), Chapter 3.2.4)
|
||||
* telnet-server ([NSA](https://apps.nsa.gov/iaarchive/library/ia-guidance/security-configuration/operating-systems/guide-to-the-secure-configuration-of-red-hat-enterprise.cfm), Chapter 3.2.2)
|
||||
* rsh-server ([NSA](https://apps.nsa.gov/iaarchive/library/ia-guidance/security-configuration/operating-systems/guide-to-the-secure-configuration-of-red-hat-enterprise.cfm), Chapter 3.2.3)
|
||||
* prelink ([open-scap](https://static.open-scap.org/ssg-guides/ssg-sl7-guide-ospp-rhel7-server.html#xccdf_org.ssgproject.content_rule_disable_prelink))
|
||||
|
||||
## Disabled filesystems
|
||||
|
||||
We disable the following filesystems, because they're most likely not used:
|
||||
|
||||
* "cramfs"
|
||||
* "freevxfs"
|
||||
* "jffs2"
|
||||
* "hfs"
|
||||
* "hfsplus"
|
||||
* "squashfs"
|
||||
* "udf"
|
||||
* "vfat" # only if uefi is not in use
|
||||
|
||||
To prevent some of the filesystems from being disabled, add them to the `os_filesystem_whitelist` variable.
|
||||
|
||||
## Example Playbook
|
||||
|
||||
```yaml
|
||||
- hosts: localhost
|
||||
collections:
|
||||
- devsec.hardening
|
||||
roles:
|
||||
- devsec.os_hardening
|
||||
```
|
||||
|
||||
## Changing sysctl variables
|
||||
|
||||
If you want to override sysctl-variables, you can use the `sysctl_overwrite` variable (in older versions you had to override the whole `sysctl_dict`).
|
||||
So for example if you want to change the IPv4 traffic forwarding variable to `1`, do it like this:
|
||||
|
||||
```yaml
|
||||
- hosts: localhost
|
||||
collections:
|
||||
- devsec.hardening
|
||||
roles:
|
||||
- devsec.os_hardening
|
||||
vars:
|
||||
sysctl_overwrite:
|
||||
# Enable IPv4 traffic forwarding.
|
||||
net.ipv4.ip_forward: 1
|
||||
```
|
||||
|
||||
Alternatively you can change Ansible's [hash-behaviour](https://docs.ansible.com/ansible/latest/reference_appendices/config.html#default-hash-behaviour) to `merge`, then you only have to overwrite the single hash you need to. But please be aware that changing the hash-behaviour changes it for all your playbooks and is not recommended by Ansible.
|
||||
|
||||
## Improving Kernel Audit logging
|
||||

By default, any process that starts before the `auditd` daemon will have an AUID of `4294967295`. To improve this and provide more accurate logging, it's recommended to add the kernel boot parameter `audit=1` to you configuration. Without doing this, you will find that your `auditd` logs fail to properly audit all processes.
|
||||
|
||||
For more information, please see this [upstream documentation](https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html) and your system's boot loader documentation for how to configure additional kernel parameters.
