What are some best practices for SSH security?

To enhance SSH security, consider using key-based authentication instead of passwords, disabling root login, and changing the default port.

Why is key-based authentication better than passwords?

Key-based authentication is more secure because it uses cryptographic keys, making it harder for attackers to gain access compared to guessing passwords.

Should I disable password authentication altogether?

Yes, if you are using key-based authentication, it's advisable to disable password authentication to prevent brute-force attacks.

What about using a firewall with SSH?

Using a firewall is a great idea! It can restrict access to your SSH port, allowing only trusted IP addresses to connect.

Are there any tools to help monitor SSH access?

Yes, tools like Fail2Ban can help monitor and block suspicious SSH access attempts, enhancing your server's security.
