- UFW (Uncomplicated Firewall): A simple-to-use firewall tool that helps manage incoming and outgoing connections.
- Snap Packages: Securely delivers and updates applications, providing an additional layer of protection.
Additional Security Measures:
- Livepatching: Allows for kernel updates without rebooting, reducing downtime and enhancing security.
- Secure Boot: Ensures that only trusted software runs on the system, preventing bootkits and rootkits.
Ease of Use: Simplifying Server Management
Ubuntu Server 20.04 LTS is designed to be user-friendly, even for those new to Linux. Its intuitive interfaces and comprehensive documentation make it easier to set up and maintain a server.
