There are numerous methods through which you can use Raspberry Pi. It can be deployed for IOT and controlling several smart devices. One of the best things that it can be used for is remote access using ssh. However, it can involve a number of problematic and serious threats. So, in this article, we will try to look at some of the steps that we can take to avoid some issues.

What is ssh

It is a network protocol that can be used for connecting to a computer securely over a network. It enables an encrypted connection to allow people to transfer files from one computer to another. Through this network, you can control your Raspberry Pi from any corner of the world. This kind of setup is especially for Raspberry Pi having no displays.

Enabling SSH on Raspberry Pi

It can be enabled on Raspberry Pi in a few different ways. First of all, we can use a keyboard and mouse, along with the monitor, to do so. On the other hand, we can use a pen drive, which has a specific file created for a particular purpose. This special method allows us to remotely access Raspberry Pi from the first boot.

Changing the default credentials

First of all, the biggest issue with Raspberry Pi is that every single device has its own predefined username and password. However, in order to make it more secure we need to create a new password. This will ensure that the device is safe from any external attacks from hackers.

Using SSH key authentication

Another important way to log in is through key authentication. It involves two cryptography keys, which are public and private keys. The public key is stored on the Raspberry, and the other one is stored on your computer. Only users with matching keys can access the Raspberry. So, you will not have to enter the password every time you log in. Thus, it removes the hustle of authentication each and every time.

Changing the default SSH port

Another essential way is to change the default ssh port. It will allow you to keep your system secure by avoiding any kind of hackers. So, such implementation will also add an extra level of security. Additionally, you will also have to update your connection settings to reflect the changes in port.

Using fail2ban for extra protection

Another important point that you need to remember is fail2ban. It will help you in making your system secure by blocking unauthorized access. This involves a user, who has attempted to log in with a wrong password. So, for a certain duration, that user will be blocked. Such protection is useful to avoid brute-force attacks.

So, these are some of the points that will help us in establishing Raspberry Pi remote access. Such kind of implementations of Remote SSH into Raspberry Pi are highly advantageous for IoT device management. This kind of implementation helps people to remotely control their IoT devices. So, Remote SSH Access can be highly beneficial for people, who want to experiment with remote IoT device management.
