1. Enable a Firewall:
The first and most important step in securing your Ubuntu 20.04 desktop is to enable the built-in firewall. By default, the UFW (Uncomplicated Firewall) is disabled so you need to enable it to protect your system.
2. Install Security Updates:
It is important to keep your system up to date with the latest security patches and updates. To ensure that your system is always up to date, you can enable automatic updates in the Software & Updates settings.
3. Use Strong Passwords:
Using strong passwords is one of the most important steps in securing your Ubuntu 20.04 desktop. It is important to use long passwords that include a combination of upper and lowercase letters, numbers, and symbols.
4. Install Antivirus Software:
It is also important to install antivirus software on your Ubuntu 20.04 desktop. This will help protect your system from malicious software and viruses that can compromise your system’s security.
5. Enable Encryption:
It is also important to enable encryption on your Ubuntu 20.04 desktop. This will help protect your data from being accessed by unauthorized users. The easiest way to enable encryption is to use the built-in encryption tool in Ubuntu.
6. Disable Unnecessary Services:
Finally, it is important to disable any unnecessary services on your Ubuntu 20.04 desktop. This will help reduce the attack surface and make it more difficult for malicious actors to gain access to your system.
1. Make sure to always keep your system up–to–date: You should update your Ubuntu 20.04 regularly to ensure you are receiving the latest security patches and bug fixes. To do this, open your Ubuntu Software Center and go to the Updates tab. From here, you can choose which updates to install.
2. Install a firewall: A firewall is essential for keeping malicious traffic away from your system. To install a firewall on Ubuntu 20.04, open your terminal and run the command “sudo apt install ufw”. Once the installation is complete, you can configure the firewall using the ufw command.
3. Enable automatic security updates: Ubuntu 20.04 comes with an option to automatically install security updates as they become available. To enable this feature, open your terminal and type “sudo dpkg–reconfigure –plow unattended–upgrades”. Select yes when it prompts you to enable security updates.
4. Enable login alerts: Login alerts will alert you whenever someone attempts to access your system. To enable this feature, open System Settings and go to Security & Privacy. On the “Privacy” tab, select the “Alerts” option, and then enable the “Login Notifications” option.
5. Encrypt your home folder: Encrypting your home folder will protect your data from unauthorized access. To enable encryption, open your terminal and type “ecryptfs–setup–private”. When prompted, enter your password and select the “Encrypt Home Folder” option.
6. Use secure passwords: Using strong, unique passwords is one of the best ways to secure your system. Avoid using dictionary words, personal details, or passwords that are easy to guess. You should also use a password manager to store your passwords securely.
