Tips to secure your Raspberry Pi

Several threats in your Raspberry Pi device might lead to critical data loss. You have to take precautionary measures to secure your Raspberry Pi device. Here, you will find the key security tips that will help you secure your Raspberry Pi.

1: Set a Unique Password

Setting a unique password is one of the important tips that will secure your device being accessed from an unknown person. The Raspberry Pi device comes up with the default username and password, which is easily accessible to everyone; thus, it’s necessary to set a unique and strong password for your Raspberry Pi device.

2: Install Antivirus Software

Linux based operating systems hardly get attacked by viruses because of their robust security. Still, they are not completely out of danger. An antivirus is a pretty useful software that will increase the security of your Raspberry Pi device. Having antivirus software will reduce the chances of your Raspberry Pi being hacked easily, thus allowing users to use the device freely.

Some anti-virus software also keeps your device in check, monitoring different applications that cause your Raspberry Pi to become slow; hence is very useful in increasing your system speed. You can install ClamAV on your Raspberry Pi device, which is lightweight antivirus software that runs in the background and secures your system from viruses.

3: Properly Shutdown your Raspberry Pi

Shutting down your Raspberry Pi device in an improper way may damage your Raspberry Pi device, which may lead to crucial data loss. Whenever you want to shut down your Raspberry Pi device, don’t unplug it; instead, use the “shutdown” command in the terminal to properly shut down your device.

4: Keep your System Updated

Keeping your Raspberry Pi updated will ensure the successful installation of the latest security updates for your device that will surely enhance its protection. Whenever you try to install a software or package, make it your habit first to run the update and upgrade command to ensure that your system and packages are up to date. The following two commands are used for this case.

$ sudo apt update

$ sudo apt upgrade
