Navigate to "Interface Options" and then select "SSH" to enable it.

Step 3: Setting Up a Static IP Address (Recommended)

While not strictly necessary, setting up a static IP address for your Raspberry Pi is highly recommended. This ensures that your Raspberry Pis IP address remains constant, making it easier to connect to it remotely. You can configure a static IP address through your router's administration panel or directly on your Raspberry Pi. Consult your router's documentation for instructions on how to assign a static IP address.

Step 4: Configuring the Firewall (if applicable)

If you have a firewall enabled on your network, you may need to configure it to allow SSH traffic. SSH typically uses port 22. Ensure that your firewall allows incoming connections on port 22. If you are using a cloud service, ensure that the security settings allow traffic on port 22.

Step 5: Securing Your Raspberry Pi

Security is paramount. After enabling SSH, you must take steps to secure your Raspberry Pi. Change the default password immediately. Also, consider using SSH keys instead of passwords for authentication. This is a more secure method as it eliminates the risk of password brute-force attacks. You can generate SSH keys on your local computer and then copy the public key to your Raspberry Pi. Also, consider disabling password-based authentication entirely and only allowing key-based authentication.
