These days the most talked about term in every enterprise is cloud-computing and living on the clouds. However we need to ensure a few things in this cloud-era:
Do we have these three musketeers always with us when we dial-in to the Internet and go online? How many times we have installed a new Windows computer, been online for a few hours and then found with an installed version of Antivirus/Antispyware tool which complains that there have been a few privacy infringing third-party tracker cookies on the light end or an extreme case of financial information/identify theft to a rogue website.
Though we can have the right antivirus software loaded we also need to ensure its patterns are updated. One more level of good security is to have DNS level protection. There are a few services like OpenDNS, Norton DNS, ScrubIt which provides the following advantages:
- Rogue sites are automatically blocked for you. Since your name server is the only which guides you a route to a website and if that blocks a harmful website without letting the address you are not in any way left the way to fall in burning fire of hell.
- Unlike a few ISPs they have old DNS software that they do not update frequently and/or also have only a few DNS servers which are often overloaded at peak times, these expert specialised DNS services have name servers scattered across data centers throughout the globe. If one name server fails in a data center the next one some where in other part of the world automatically assumes its roles and starts to protect you.
How to configure and use it?
Just set the DNS of your computer to the name servers given by that service and the next launch of the web browser would escort your journey in the internet superhighway with the security expertise of the experts.
