Security of smart devices

How can you maintain the security of your smart devices?

  • Use the newest version of any software on your device. Make sure that automatic security updates are enabled.
  • Only download applications from the official store of the manufacturer of your device (Google Play Store, Apple’s App Store, or Windows Store). When downloading an application, also check the information on its developer and feedback from its users.
  • Check the privacy settings of applications (also after updates) and see what kind of data each app can access on your phone.
  • Install antivirus software also on your phone and make sure it is activated and in use.
  • Use a screen lock to protect your phone and privacy. You can also add a password or security code to applications to improve the protection of your personal information. Do not use common simple patterns or number combinations for your screen lock.
  • Do not open unknown e-mails, links, or attachments. If someone you know sends a link or attachment by e-mail, but writes differently from the usual, ask for clarification. As smart devices act as a replacement for personal computers for many people, malware has been created to target smart devices specifically.
  • If possible, use mobile data instead of WiFi in public places. Remove unnecessary WiFi networks from your device at least once every six months to prevent your phone from connecting to identically named WiFi networks set up for malicious purposes.
  • In order to prevent the loss of important contacts and files, make regular back-up copies of the files and information on your phone to the memory card of the phone or to an account linked with the phone.
  • To provide extra security, encrypt the contents of your phone under Settings, if possible, to make sure any information on the device does not end up in the wrong hands.
  • Turn on ‘Find my phone’ on your device so that you could locate it if it is lost.
