"<p>In this video, we're going to show you how to configure a firewall on your system using UFW (Uncomplicated Firewall) and Ansible. We'll walk you through the process step-by-step and provide you with the code you need to customize the firewall rules to fit your needs.</p> <p>First up, we'll cover how to install UFW if you don't already have it on your system. Then we'll move on to configuring UFW policies, so you can define how incoming and outgoing traffic should be handled. Thanks to Ansible, you can easily choose to deny or allow traffic in each direction.</p> <p>Next, we'll show you how to limit SSH connections for added security. By setting a rule that restricts the number of SSH connections, you can help protect your system from brute-force attacks and unauthorized access.</p> <p>We'll also cover how to allow HTTP and HTTPS connections, so you can enable web traffic to your server. We'll walk you through defining the necessary rules to permit communication over the relevant ports.</p> <p>Finally, we'll guide you through activating UFW to ensure that your firewall rules take effect and your system is safeguarded.</p> <p>Whether you're a newbie or an experienced sysadmin, this video is designed to help you configure your firewall using UFW and Ansible with ease. So let's get started!</p> <pre> --- # tasks file for firewall - name: Installing UFW apt: name: ufw state: present - name: configure UFW policies ufw: direction: "{{ item.direction }}" policy: "{{ item.policy }}" with_items: - { direction: incoming , policy: deny} - { direction: outgoing , policy: allow} - name: limit ssh connections ufw: rule: limit port: ssh - name: allow http(s) connections ufw: rule: allow port: "{{ item }}" with_items: - http - https - name: activate UFW ufw: state: enabled</pre>"
