Introduction to home Router security

Last updated on by srs_wubwub

The majority of home broadband users will use a single Router which is connected to a DSL cable to provide access to the internet for the home network. This single piece of equipment is a combination of what would previously have been individual devices:

  • DSL Modem

  • Switch

  • Router

  • Wireless Access Point

Your router holds information which is essential to the operation of your internet connection and so should be protected.

Whilst using your internet browser you will likely want to navigate to websites, for example. Your router handles this request by understanding that is not stored within your home network and must be outside on another network. It will use the configured DNS settings to find out where is, this will be relayed back to it as an IP Address ( Using this address the relevant website will be loaded.

Access to your router allows the configuration of DNS server settings which could be changed in such a manner that instead of being directed to the real ( you could be directed to a specially crafted phishing website which looks and acts in the exact same way as the real site. The difference is that when you log in with your user credentials you will not enter your account and the malicious individual now has your login information. Many people use the same username and password combination for multiple websites so you have given the details for all of these accounts to a malicious user in one instance. 

This is one reason why you should move away from using the common administrative username and password combinations which can be found online. I will be producing a number of guides for specific routers for how to change the login information but for the mean time you may be able to complete this change for yourself.

First find your router IP Address, this can be found on the documentation provided with your router and the most common addresses are listed at the bottom of this article with some specific guides found on the Freeola Help & Support Centre. Once logged into your device you will need to find a section which is marked 'System Settings' or 'Security', within this section you will look for 'Administrator Password'. Follow the on-screen prompts to change your password.

This is an extremely easy step towards securing your network users whilst using the internet.
