Smart device definition

A smart device is an electronic gadget that’s connected to the internet and can do more than its basic functions. It’s like a regular device — a thermostat, TV, or fridge — only with advanced functions like remote control, automation, and voice commands. Smart devices are designed to make everyday tasks easier and more convenient.

Smart devices and cybersecurity

  • Privacy concerns. Smart devices often collect and transmit data, including personal information. Users should be aware of what data their devices collect and how it is used by reviewing privacy settings, terms, and conditions.
  • Targets for cyberattacks. Hackers often target smart devices because once compromised, these devices can wreak havoc. Having multiple smart devices means more points of attack for cybercriminals to target.
  • Weak passwords. Weak or default passwords are a common security risk. Users should change default passwords and create unique passwords for each smart device.
