1. AppArmor

   • Configure AppArmor profiles for enhanced application security.

2. SSH Hardening

   • Strengthen SSH configuration for improved access control.

3. Kernel Hardening

   • Implement kernel-level security measures.

4. Tor Blocking

   • Block TOR network to enhance network security.

5. Antivirus Installation

   • Install antivirus software for added protection.

6. Enable Auditing

   • Enable system auditing for monitoring and analysis.

7. Fail2Ban

   • Set up Fail2Ban to protect against brute-force attacks.

8. Grub Secure

   • Secure Grub bootloader configuration.

9. USB Blocking

   • Restrict USB access for increased security.

10. Firewall Setup

    • Configure a firewall to control incoming and outgoing traffic.

Settings can be configured according to the user's convenience and preferences(organizational needs). The hardening features are divided into a couple levels, as mentioned in CIS Benchmarks. Shieldbuntu leverages the lightweight Tauri framework, combining the flexibility of React for the GUI and the security of Rust for the backend.
