Securing a system goes beyond initial installation; post-installation maintenance is crucial to maintaining long-term security. After setting up your Ubuntu-based distro, follow these steps to further enhance system security:

• Configure UFW for Default Deny: After enabling UFW, it’s essential to configure it to block all incoming traffic by default, allowing only necessary connections. Use the following command:

sudo ufw default deny incoming

This sets the firewall to deny all incoming connections unless explicitly allowed, reducing the risk of unauthorized access.

• Backup and Recovery: Regular backups are a vital part of maintaining a secure system. You should set up automated backup solutions to ensure your data is regularly backed up and can be quickly restored in case of an attack. Tools like rsync or dedicated backup software can be configured for this purpose.
• System Monitoring and Logging: Implementing system monitoring tools like fail2ban and reviewing logs regularly can help identify potential security threats before they escalate. fail2ban blocks IP addresses after repeated failed login attempts, adding an additional layer of defense against brute-force attacks.

By following these post-installation maintenance practices, you can ensure that your Ubuntu-based distro remains secure and resilient to ongoing threats.
