 ## 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 Puppet head to the [Puppet Forge](https://forge.puppetlabs.com/) and take a node of the Puppet supported modules.

 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.

 ## 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).
+This collection provides battle tested hardening for:
 
-It configures:
+- Linux operating systems:
+  - CentOS 7/8
+  - Debian 9/10
+  - Ubuntu 16.04/18.04/20.04
+  - Amazon Linux (some roles supported)
+  - Arch Linux (some roles supported)
+  - Fedora (some roles supported)
+  - Suse Tumbleweed (some roles supported)
+- MySQL
+  - MariaDB >= 5.5.65, >= 10.1.45, >= 10.3.17
+  - MySQL >= 5.7.31, >= 8.0.3
+- Nginx 1.0.16 or later
+- OpenSSH 5.3 and later
 
- * Configures package management e.g. allows only signed packages
- * Remove packages with known issues
- * Configures `pam` and `pam_limits` module
- * Shadow password suite configuration
- * Configures system path permissions
- * Disable core dumps via soft limits
- * Restrict root Logins to System Console
- * Set SUIDs
- * Configures kernel parameters via sysctl
- * Install and configure auditd
+The hardening is intended to be compliant with the Inspec DevSec Baselines:
 
-It will not:
+- https://github.com/dev-sec/linux-baseline
+- https://github.com/dev-sec/mysql-baseline
+- https://github.com/dev-sec/nginx-baseline
+- https://github.com/dev-sec/ssh-baseline
 
- * Update system packages
- * Install security patches
+## Looking for the old ansible-os-hardening role?
 
-## Requirements
+This role is now part of the hardening-collection. You can find the old role in the branch `legacy`.
 
-* Ansible 2.5.0
+## Minimum required Ansible-version
 
-## Warning
+- Ansible >= 2.9.10
 
-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).
+## Included content
 
-If you're using Docker / Kubernetes+Docker you'll need to override the ipv4 ip forward sysctl setting.

-## Variables
-
-| Name           | Default Value | Description                        |
-| -------------- | ------------- | -----------------------------------|
-| `os_desktop_enable`| false |  true if this is a desktop system, ie Xorg, KDE/GNOME/Unity/etc|
-| `os_env_extra_user_paths`| [] | add additional paths to the user's `PATH` variable (default is empty).|
-| `os_env_umask`| 027| set default permissions for new files to `750` |
-| `os_auth_pw_max_age`| 60 | maximum password age (set to `99999` to effectively disable it) |
-| `os_auth_pw_min_age`| 7 | minimum password age (before allowing any other password change)|
-| `os_auth_retries`| 5 | the maximum number of authentication attempts, before the account is locked for some time|
-| `os_auth_lockout_time`| 600 | time in seconds that needs to pass, if the account was locked due to too many failed authentication attempts|
-| `os_auth_timeout`| 60 | authentication timeout in seconds, so login will exit if this time passes|
-| `os_auth_allow_homeless`| false | true if to allow users without home to login|
-| `os_auth_pam_passwdqc_enable`| true | true if you want to use strong password checking in PAM using passwdqc|
-| `os_auth_pam_passwdqc_options`| "min=disabled,disabled,16,12,8" | set to any option line (as a string) that you want to pass to passwdqc|
-| `os_security_users_allow`| [] | list of things, that a user is allowed to do. May contain `change_user`.
-| `os_security_kernel_enable_module_loading`| true | true if you want to allowed to change kernel modules once the system is running (eg `modprobe`, `rmmod`)|
-| `os_security_kernel_enable_core_dump`| false | kernel is crashing or otherwise misbehaving and a kernel core dump is created |
-| `os_security_suid_sgid_enforce`| true | true if you want to reduce SUID/SGID bits. There is already a list of items which are searched for configured, but you can also add your own|
-| `os_security_suid_sgid_blacklist`| [] | a list of paths which should have their SUID/SGID bits removed|
-| `os_security_suid_sgid_whitelist`| [] | a list of paths which should not have their SUID/SGID bits altered|
-| `os_security_suid_sgid_remove_from_unknown`| false | true if you want to remove SUID/SGID bits from any file, that is not explicitly configured in a `blacklist`. This will make every Ansible-run search through the mounted filesystems looking for SUID/SGID bits that are not configured in the default and user blacklist. If it finds an SUID/SGID bit, it will be removed, unless this file is in your `whitelist`.|
-| `os_security_packages_clean`| true | removes packages with known issues. See section packages.|
-| `os_selinux_state` | enforcing | Set the SELinux state, can be either disabled, permissive, or enforcing. |
-| `os_selinux_policy` | targeted | Set the SELinux polixy. |
-| `ufw_manage_defaults` | true | true means apply all settings with `ufw_` prefix|
-| `ufw_ipt_sysctl` | '' | by default it disables IPT_SYSCTL in /etc/default/ufw. If you want to overwrite /etc/sysctl.conf values using ufw - set it to your sysctl dictionary, for example `/etc/ufw/sysctl.conf`
-| `ufw_default_input_policy` | DROP | set default input policy of ufw to `DROP` |
-| `ufw_default_output_policy` | ACCEPT | set default output policy of ufw to `ACCEPT` |
-| `ufw_default_forward_policy` | DROP | set default forward policy of ufw to `DROP` |
-| `os_auditd_enabled` | true | Set to false to disable installing and configuring auditd. |
-| `os_auditd_max_log_file_action` | `keep_logs` | Defines the behaviour of auditd when its log file is filled up. Possible other values are described in the auditd.conf man page. The most common alternative to the default may be `rotate`. |
-| `hidepid_option` | `2` | `0`: This is the default setting and gives you the default behaviour. `1`: With this option an normal user would not see other processes but their own about ps, top etc, but he is still able to see process IDs in /proc. `2`: Users are only able too see their own processes (like with hidepid=1), but also the other process IDs are hidden for them in /proc. |
-| `proc_mnt_options` | `rw,nosuid,nodev,noexec,relatime,hidepid={{ hidepid_option }}` | Mount proc with hardenized options, including `hidepid` with variable value. |

-## 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.

 ## Installation
 
-Install the role with ansible-galaxy:
+Install the collection via ansible-galaxy:
 
-```
-ansible-galaxy install dev-sec.os-hardening
-```
+`ansible-galaxy collection install devsec.hardening`
 
-## Example Playbook
+## Using this collection
 
-```yaml
-- hosts: localhost
-  roles:
-    - dev-sec.os-hardening
-```
+Please refer to the examples in the readmes of the role.
 
-## Changing sysctl variables
+See [Ansible Using collections](https://docs.ansible.com/ansible/latest/user_guide/collections_using.html) for more details.
 
-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:
+## Contributing to this collection
 
-```yaml
-- hosts: localhost
-  roles:
-    - dev-sec.os-hardening
-  vars:
-    sysctl_overwrite:
-      # Enable IPv4 traffic forwarding.
-      net.ipv4.ip_forward: 1
-```
+See the [contributor guideline](CONTRIBUTING.md).
 
-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.
+## Release notes
 
-## Improving Kernel Audit logging
+See the [changelog](https://github.com/dev-sec/ansible-os-hardening/tree/master/CHANGELOG.md).
 
-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. 
+## Roadmap
 
-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. 
+Todos:
 
-## Local Testing
+- Work on [apache_hardening](roles/apache_hardening/) and [windows_hardening](roles/windows_hardening/).
+- Add support for more operating systems,
 
-The preferred way of locally testing the role is to use Docker. You will have to install Docker on your system. See [Get started](https://docs.docker.com/) for a Docker package suitable to for your system.
+## More information
 
-You can also use vagrant and Virtualbox or VMWare to run tests locally. You will have to install Virtualbox and Vagrant on your system. See [Vagrant Downloads](http://downloads.vagrantup.com/) for a vagrant package suitable for your system. For all our tests we use `test-kitchen`. If you are not familiar with `test-kitchen` please have a look at [their guide](http://kitchen.ci/docs/getting-started).

+![devsec.nginx_hardening](https://github.com/dev-sec/ansible-os-hardening/workflows/devsec.nginx_hardening/badge.svg)
+
+## Description
+
+This role provides secure nginx configuration. It is intended to be compliant with the [DevSec Nginx Baseline](https://github.com/dev-sec/nginx-baseline).
+
+It works with the following nginx-roles, including, but not limited to:
+
+- [geerlingguy.nginx](https://galaxy.ansible.com/geerlingguy/nginx/)
+- [nginxinc.nginx](https://galaxy.ansible.com/nginxinc/nginx)
+- [jdauphant.nginx](https://galaxy.ansible.com/jdauphant/nginx/)
+- [franklinkim.nginx](https://galaxy.ansible.com/franklinkim/nginx/)
+
+**NOTE: This role does not work with nginx 1.0.15 or older! Please use the latest version from the official nginx repositories!**
+
+## Requirements
+
+- Ansible >= 2.9
+
+## Role Variables
+
+- [nginx_client_body_buffer_size][]
+  - Default: `1k`
+  - Description: Sets buffer size for reading client request body. In case the request body is larger than the buffer, the whole body or only its part is written to a temporary file.
+- nginx_remove_default_site
+  - Default: `true`
+  - Description: Disables the default site. Set to false to enable the default site in nginx.
+- [nginx_client_max_body_size][]
+  - Default: `1k`
+  - Description: Sets the maximum allowed size of the client request body, specified in the “Content-Length” request header field. If the size in a request exceeds the configured value, the 41
+    3 (Request Entity Too Large) error is returned to the client.
+- [nginx_keepalive_timeout][]
+  - Default: `5 5`
+  - Description: The first parameter sets a timeout during which a keep-alive client connection will stay open on the server side. The zero value disables keep-alive client connections. The op
+    tional second parameter sets a value in the “Keep-Alive: timeout=time” response header field.
+- [nginx_server_tokens][]
+  - Default: `off`
+  - Description: Disables emitting nginx version in error messages and in the "Server" response header field. Set to on to enable the nginx version in error messages and "Server" response head
+    er.
+- [nginx_client_header_buffer_size][]
+  - Default: `1k`
+  - Description: Sets buffer size for reading client request header. For most requests, a buffer of 1K bytes is enough.
+- [nginx_large_client_header_buffers][]
+  - Default: `2 1k`
+  - Description: Sets the maximum number and size of buffers used for reading large client request header.
+- [nginx_client_body_timeout][]
+  - Default: `10`
+  - Description: Defines a timeout for reading client request body.
+- [nginx_client_header_timeout][]
+  - Default: `10`
+  - Description: Defines a timeout for reading client request header.
+- [nginx_send_timeout][]
+  - Default: `10`
+  - Description: Sets a timeout for transmitting a response to the client.
+- [nginx_limit_conn_zone][]
+  - Default: `$binary_remote_addr zone=default:10m`
+  - Description: Sets parameters for a shared memory zone that will keep states for various keys.
+- [nginx_limit_conn][]
+  - Default: `default 5`
+  - Description: Sets the shared memory zone and the maximum allowed number of connections for a given key value.
+- [nginx_add_header][]
+  - Default: `[ "X-Frame-Options SAMEORIGIN", "X-Content-Type-Options nosniff", "X-XSS-Protection \"1; mode=block\"" ]`
+  - Description:Adds the specified field to a response header provided that the response code equals 200, 201, 204, 206, 301, 302, 303, 304, or 307.
+- [nginx_ssl_protocols][]
+  - Default: `TLSv1.2`
+  - Description: Specifies the SSL protocol which should be used.
+- [nginx_ssl_ciphers][]
+  - Default: _see defaults.yml_
+  - Description: Specifies the TLS ciphers which should be used.
+- [nginx_ssl_prefer_server_ciphers][]
+  - Default: `on`
+  - Description: Specifies that server ciphers should be preferred over client ciphers when using the TLS protocols. Set to false to disable it.
+- [nginx_dh_size][]
+  - Default: `2048`
+  - Description: Specifies the length of DH parameters for EDH ciphers.

+
+## 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:
+
+- Removes unused yum repositories and enables GPG key-checking
+- Removes packages with known issues
+- Configures pam for strong password checks
+- Installs and configures auditd
+- Disables 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
+- Removes 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.hardening.os_hardening
+  vars:
+    sysctl_overwrite:
+      # Enable IPv4 traffic forwarding.
+      net.ipv4.ip_forward: 1
+```
+
+### hidepid on RHEL/CentOS 7
+
+When having `polkit-0.112-18.el7` (and later) installed and `/proc` mounted with `hidepid=2`, everytime someone uses `systemctl` the following error is displayed, but systemctl runs successfully.
+
+```
+Error registering authentication agent: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Cannot determine user of subject (polkit-error-quark, 0)
+```
+
+We decided to set `hidepid=0` to remove the error message, if you want to use the other proposed workaround, you have to setup the user yourself and set our option to `hidepid_option: 2` via Ansible vars.
+
+For further details see [RedHat: "GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Cannot determine user of subject" seen when executing systemctl command](https://access.redhat.com/solutions/5005111) or [#364: hidepid=2 gives error when running systemctl on EL7](https://github.com/dev-sec/ansible-collection-hardening/issues/364)
+
+### 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.hardening.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.

+  - Description: `0`: This is the default setting and gives you the default behaviour. `1`: With this option an normal user would not see other processes but their own about ps, top etc, but he is still able to see process IDs in /proc. `2`: Users are only able too see their own processes (like with hidepid=1), but also the other process IDs are hidden for them in /proc.
+- `proc_mnt_options`
+  - Default: `rw,nosuid,nodev,noexec,relatime,hidepid={{ hidepid_option }}`
+  - Description: Mount proc with hardenized options, including `hidepid` with variable value.
+- `os_ignore_home_folder_users`

+## Packages
+
+We remove the following packages:

+
+## 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:
+    - 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:
+    - 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.
+
+## More information
+
+We use specific PAM configuration for every linux distribution. This is a very diverse area, since every vendor seems to push their own system for managing PAM. We used following guides and sources for our configuration.
+
+- on Debian/Ubuntu we use [pam-config-framework](https://wiki.ubuntu.com/PAMConfigFrameworkSpec)
+- RHEL8 and compatible use information from [authselect](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_authentication_and_authorization_in_rhel/configuring-user-authentication-using-authselect_configuring-authentication-and-authorization-in-rhel), but our setup disables the configuration from authselect
+- RHEL 6/7 and compatible use [authconfig](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/system-level_authentication_guide/authconfig-install), but our setup disables the configuration from authconfig
+- for RHEL 6/7 we also use information from [Desktop Security](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/security_guide/chap-hardening_your_system_with_tools_and_services#sec-Desktop_Security)
+
+This role is mostly based on guides by:
+
+- [Arch Linux wiki, Sysctl hardening](https://wiki.archlinux.org/index.php/Sysctl)
+- [NSA: Guide to the Secure Configuration of Red Hat Enterprise Linux 5](http://www.nsa.gov/ia/_files/os/redhat/rhel5-guide-i731.pdf)
+- [Ubuntu Security/Features](https://wiki.ubuntu.com/Security/Features)
