Anyone who owns an unprotected device that is always connected to the internet, like a home router, can make spying possible for foreign intelligence agencies, tells suojelupoliisi (Supo) in their new security report.

More and more devices have an internet connection that allows the device to be remotely controlled from the public internet.

It can provide a possibility for state intelligence agencies to use the device remotely without permission, which they do in attempt to penetrate into information systems of Finland and its allies.

  Router is an essential part in protecting a home
  
Router is a device that connects other devices to the internet. For example computers, mobile devices and many other smart devices like household appliances, entertainment systems and gaming consoles are usually connected to the internet either via the router directly or via a wifi network that is made possible by the router.

Because the router controls all network traffic, it is an important part of protecting the devices in the wireless network from external threats, like hackers and denial-of-service attacks.

According to supo, particularly unprotected and unupdated home routers form a significant risk to national security.

Hijacked home routers can be used, for example, as a part of a wide denial-of-service attack, in attempt to bring down company websites, governmental online services and home pages.


  Change the default password to something more complex

Change the router's default password to a strong password. The most important property of a strong password is its length. Special characters, like upper and lower case letters and adding numbers make the password even safer. [Translation note: The previous sentence has a similarly vague grammar also in its Finnish version.]

It's not recommended to use the same password in more than one accounts and devices. If one service leaks the password, then the other ones are also in danger.

  Check at least these six easy ways of protection
  
- Use firewall.

- Block remote access to the device from the internet so that the device cannot be reached [?] from the public network

- Run software- and device upgrades (firmware) and keep them up to date

- Create a separate network for IoT devices (Internet of Things). This way poorly protected IoT devices don't provide attack surface to hackers and endanger your computers and phones by doing so.

- Power down your router regularly.

- Disable features that you don't need.
