Safety in using internet-connected devices

In addition to your computer, you should also ensure an adequate level of information security for other internet-connected devices. When you start using a new device, the most important thing to do is to check its settings.

Many devices, such as new television sets or digital set-top-boxes, can be connected to the internet. With the network connection, you can use entertainment services provided online or update the device's firmware and software.

In an unsecured network, it is easy for other users to see and listen to unencrypted communications. Others can also use an unsecured network unauthorised. Check all the devices that are used for connecting to the internet or that are directly connected to the internet. Such devices include the following:

  • ADSL modem
  • WLAN base station
  • separate firewall devices.

Block access from the internet to the devices' control panels and change the default passwords of the devices. The most important aspect in creating a strong password is the length of the password. The recommended minimum length of a password is 12 characters. Even a long password may not be safe if it is easy to guess (e.g. mypassword1) or too simple (e.g. 112233445566). A strong password is long and complex.

Check also the security settings of your wireless network.
