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.

6: Remove Unnecessary Apps

If you are not using any application on your Raspberry Pi device anymore, it’s better to remove it from your system to free up your Raspberry Pi storage, as excess storage will increase your device’s power consumption and may result in lowering your device performance. You can remove the application from your Raspberry Pi terminal via the following command.

7: Use Reliable Power Supply

A good power supply option is compulsory for your Raspberry Pi device as this will significantly impact your device performance. A poor-quality power supply reduces your Raspberry Pi performance and may damage your device. Thus, have a suitable power supply with DC output voltage 5.1V with 3A current (15.3W) for your Raspberry Pi. Luckily, Raspberry Pi notifies you when the power supply is insufficient.

8: Avoid Overclocking

Overclocking highly impacts your device’s performance. Overclocking too much will damage your device, and it may cause it not to boot up properly. To ensure that your device is overclocked at a reasonable rate get help from our published article.

Conclusion

The Raspberry Pi device is a useful little tool helping people in various ways. However, the Raspberry Pi users must need precautionary measures to secure their Raspberry Pi device regarding security and privacy to ensure their data protection. The above-mentioned tips will help them secure their Raspberry Pi devices effectively.
