Hardware security

Hardware security is all about keeping the physical things your computer uses - like the actual computer or phone, the electric cords and wires attached to it, the memory card, or even the USB drive - safe and secure. That means making sure that no one can access them or manipulate them in a way that could harm the computer or put your data and information at risk. To do this, it is important to never leave your computer or phone unattended and to keep your passwords and other security measures up-to-date. In addition, lock or password protect your devices and be cautious when allowing others to borrow or use your devices.
