From: Get Cyber Safe
Billions of devices are connected to the internet, with more coming online every day. Mobile phones, laptops, smart watches, automobiles and even buildings are connected to the web. But this growing interconnectedness comes with some risks. When a device connects to the internet, it exchanges information with devices and networks across the globe. During these exchanges your personal data can be exposed and your devices can be accessed by unauthorized users. Firewalls help ensure that you control who can access your device – keeping you safe, and your data secure.
