Securing your Ubuntu 22.04 server and services like nginx and mysql can greatly enhance the overall defense of your system against potential threats. Here are some best practices and guidance materials you can follow:
Update Regularly: Make sure to keep your Ubuntu server, nginx, and mysql services up to date with the latest security patches by running regular system updates.
Configure Firewall: Use the built-in firewall tool, ufw (Uncomplicated Firewall), to control incoming and outgoing traffic to your server. Only allow necessary ports and services.
Secure SSH: Secure your SSH service by disabling root login, using key-based authentication, and changing the default SSH port to a custom one.
HTTPS Encryption: Configure SSL/TLS certificates to encrypt data transmitted over the web using nginx. Utilize Let’s Encrypt for free SSL certificates.
Limit User Access: Create separate user accounts with appropriate permissions and avoid using the root account for regular tasks.
Disable Unused Services: Disable any unnecessary services running on your server to reduce the attack surface.
Intrusion Detection System (IDS): Implement an IDS like Fail2Ban to monitor and prevent brute-force attacks on your server.
For more detailed guidance, you can refer to the official Ubuntu documentation, nginx documentation, and MySQL documentation. Additionally, security-focused websites like OWASP (Open Web Application Security Project) and blogs from cybersecurity experts can provide valuable insights on securing your server and services effectively.
