A person shares banking details with several online services and uses multiple connected devices. Explain why these facts matter when considering that person's cyber threat surface.
Answer
Online services and connected devices create systems or information that may be exposed to attackers. More shared personal and financial information can increase the amount of information at risk if a service is breached. The person should consider which services and devices are exposed and reduce unnecessary exposure while applying suitable safeguards.
