It only takes one site that is not up to date to allow a hacker access to the server and all its bounty. Not neglecting to update a website when there is a security release is paramount to ensuring that the server and all the other sites on it are secure. Even in our due diligence we can have many sub domains where we may be testing or building the next big thing for our clients and it is these sites that are the most vulnerable because once we are done we move on to other things and will likely forget about them until it is too late!

The domain name system is not hard to understand but yet those who are not technically savvy tend to rely on an agency or a web firm to manage it for them. There are pros and cons to this but first we need to understand how all this works so you have a solid understanding and know the risks that you are taking by not managing your own domain name.
