Ansible CIS Ubuntu 20.04 LTS Hardening V1.1.0 Latest

CIS hardened Ubuntu: cyber attack and malware prevention for mission-critical systems CIS benchmarks lock down your systems by removing:

non-secure programs.
disabling unused filesystems.
disabling unnecessary ports or services.
auditing privileged operations.
restricting administrative privileges.

CIS benchmark recommendations are adopted in virtual machines in public and private clouds. They are also used to secure on-premises deployments. For some industries, hardening a system against a publicly known standard is a criteria auditors look for. CIS benchmarks are often a system hardening choice recommended by auditors for industries requiring PCI-DSS and HIPPA compliance, such as banking, telecommunications and healthcare. If you are attempting to obtain compliance against an industry-accepted security standard, like PCI DSS, APRA or ISO 27001, then you need to demonstrate that you have applied documented hardening standards against all systems within the scope of assessment.

The Ubuntu CIS benchmarks are organised into different profiles, namely ‘Level 1’ and ‘Level 2’ intended for server and workstation environments.

A Level 1 profile is intended to be a practical and prudent way to secure a system without too much performance impact.

Disabling unneeded filesystems,
Restricting user permissions to files and directories,
Disabling unneeded services.
Configuring network firewalls.

A Level 2 profile is used where security is considered very important and it may have a negative impact on the performance of the system.

Creating separate partitions,
Auditing privileged operations

The Ubuntu CIS hardening tool allows you to select the desired level of hardening against a profile (Level1 or Level 2) and the work environment (server or workstation) for a system. Exmaple:

ansible-playbook -i inventory cis-ubuntu-20.yaml --tags="level_1_server"

You can list all tags by running the below command:

ansible-playbook -i host run.yaml --list-tags

I wrote all roles based on

CIS Ubuntu Linux 20.04 LTS Benchmark

Requirements

You should carefully read through the tasks to make sure these changes will not break your systems before running this playbook.

You can download Free CIS Benchmark book from this URL Free Benchmark

To start working in this Role you just need to install Ansible. Installing Ansible

Role Variables

You have to review all default configuration before running this playbook, There are many role variables defined in defaults/main.yml.

If you are considering applying this role to any servers, you should have a basic familiarity with the CIS Benchmark and an appreciation for the impact that it may have on a system.
Read and change configurable default values.

Examples of config that should be immediately considered for exclusion:

5.1.8 Ensure cron is restricted to authorized users and 5.2.17 Ensure SSH access is limited, which by default effectively limit access to the host (including via ssh).

For example:

CIS-Ubuntu-20.04-Ansible/defaults/main.yml

#Section 5
#5.1.8 Ensure cron is restricted to authorized users
allowed_hosts: "ALL: 0.0.0.0/0.0.0.0, 192.168.2.0/255.255.255.0"
# 5.2.17 Ensure SSH access is limited
allowed_users: ali saleh baker root #Put None or list of users space between each user

If you need you to change file templates, you can find it under files/templates/*

Dependencies

Ansible version > 2.9

Example Playbook

Below an example of a playbook

---
- hosts: host1
  become: yes
  remote_user: root
  gather_facts: no
  roles:
    - { role: "CIS-Ubuntu-20.04-Ansible",}

Run all

If you want to run all tags use the below command:

ansible-playbook -i [inventoryfile] [playbook].yaml

Run specfic section

ansible-playbook -i host run.yaml -t section2

Run multi sections

ansible-playbook -i host run.yaml -t section2 -t 6.1.1

Note: When run an individual task be sure from the dependencies between tasks, for example, if you run tag 4.1.1.2 Ensure auditd service is enabled before running 4.1.1.1 Ensure auditd is installed you will get an error at the run time.
Points with ~~Tilde~~ not implemented yet, currently I'm working on it.
make sure to select one time service, for me I use ntp, but you can use other service such as [systemd-timesyncd,ntp,chrony] under the settings defaults/main.yaml

Testing 11/1/2020 Tested on AWS EC2 ubuntu 20.04 LTS [Pass] 11/1/2020 Tested on local Ubuntu 20.04 LTS server [Pass]

Before run make sure to update user list under defaults/main.yaml on list_of_os_users + allowed_users
Make sure to set the right subnet under defaults/main.yaml on allowd_hosts

Troubleshooting

If you want to run the playbook in the same machine, make sure to add this to run task:

- hosts: 127.0.0.1
  connection: local

if you faced issue with execut, try to run the playbook in another path, like /srv/.
For error like this stderr: chage: user 'ubuntu' does not exist in /etc/passwd, make sure to update config under CIS-Ubuntu-20.04-Ansible/defaults/main.yml
