How to Prevent Your Raspberry Pi from Getting Hacked


The Raspberry Pi has gained immense popularity over the past six years since its release. People have found uses of this credit-card sized computer in almost every field of life. Whether it’s a home security system or a bathroom-occupancy detector, the pi has it covered.

However, as with all other popular devices, it has also attracted hackers who have been quite successful in finding flaws in its framework.

For instance, last year, there was a serious vulnerability in the raspberry pi’s SSH key generation mechanism that led to the exploitation of numerous devices. 

Many users of the device, however, claim that they are not particularly concerned about the pi’s security. This is primarily because a large number of pi users are hobbyists and they have no intention of bringing the pi online or using it as a server. Security only comes into the picture when the pi is brought online. 

Any flaws or holes present in the system can have devastating consequences. These consequences may range from identity theft to utter unusability of the pi.

Here are some measures that can be taken to protect your raspberry pi from hackers.

Turn off SSH when not in use

Remote SSH allows you to remotely login to your raspberry pi from another device. This can have several benefits but at the same time it can also open up a gateway for intruders to break into your pi. If you want to play safe, turn SSH off on your pi when you’re not using it.

If you cannot afford to turn SSH off, you can try installing a program called Fail2Ban on your pi. What this does is that it looks through your pi’s log files and bans any malicious IPs that have tried to break into your pi by guessing your SSH credentials.

Update your pi on every boot

After every few days, the team of developers at Raspberry Pi comes up with bug fixes to prevent pis all over the world from getting hacked. Thus, it is almost critical to keep your raspberry pi up-to-date with all the latest patches.

The simplest way to do this is by opening up the terminal and typing in the following commands: 
sudo apt-get update

sudo apt-get dist-upgrade

The first command updates your system’s package list and the second command upgrades all your installed packages to their latest versions.


Set-up a VPN service

Connecting to the internet via a Virtual Private Network ensures that all your data is sent in an encrypted format. This prevents any lousy hackers from being able to read your personal information.  Be sure to configure your Raspberry Pi to auto connect to a VPN program such as OpenVPN before sending anything over the web.

The raspberry pi has a wide array of applications and one would not want to miss out on such a useful invention just because it has some security risks surrounding it. If you follow these tips, you’re ready to roll.
