What can I do myself to protect my edpnet telephony against hacking?


As your edpnet telephony account is configured on your modem, it is important that nobody can access the interface of your device without your consent. 

  • Change the default password of your modem

Every modem has a default password (e.g., 1234, admin, etc.) which can be easily found in any manual on the Internet. If you set up your own secure password, it will not be easy to log in to your device. 

  • Disable Remote Management / Remote Administration

Remote Management / Remote Administration is a certain configuration of your modem which allows you / edpnet helpdesk / your system administrator to take full control of your device remotely. In the meanwhile, experienced abusers can also access your modem this way unless this configuration is disabled. 

Find out how to set up Remote Management / Remote Administration on your modem in its manual or contact edpnet support in case you use edpnet hardware. 
  • Set up WPA/WPA2 for your wireless network

WPA/WPA2 are two security protocols and security certification programs developed to secure wireless computer networks. They provide data encryption and require user’s authentication which makes your Wi-Fi network secure. It is strongly recommended to protect your Wi-Fi access with one of these protocols.

Find out how to set up WPA/WPA2 for your wireless network in the manual of your router or contact edpnet support in case you use edpnet hardware. 
  • Ensure your modem firmware is up-to-date

Every newer version of firmware is always an improvement over the previous firmware package. Releasing new firmware updates manufacturers take care of fixing existing bugs, correcting device issues and adding new features which can also include extra security measures. It is easier for abusers to find out how to hack devices with older firmware versions, the features of which are already well-known. Moreover, regularly updating the firmware keeps your device performing optimally.
