Digital Security and Privacy are the precautions taken to make sure the user and the device is safe. Just like an illness, viruses and other malicious attacks can spread from one machine to another. Understanding how to deal with attacks like these is an important skill to have.
Examples:
Digital Viruses can feed on information and can target others who have used a machine or are associated with it.
Phishing links are a common attack and users can be very easily fooled by them. They are often disguised as companies or people the user is familiar with and can ask for sensitive information.
