Role of DNS, Email Server And Web Server in Website’s Security

Now day’s internet security is very important for any website. If any business has a website then security should be its first concern. There are multiple things recommend to clients and to prospective clients to enhance their firm’s online security.

First of all, for redundancy, scalability and capacity, one should separate website, email, and DNS services immediately. Many business run DNS, email, and website on a single dedicated-virtual server. This type of setup is not secure and has zero fault.

Most of the hosting companies use a storage method known as “RAID 5.” Which implies that the entire data for your company email, DNS, and website are potentially kept on hard drives that have a 1-drive fault tolerance. If at all two of these storage driver broke your services will go down immediately and it would time to recover everything.

Below, I’ve outlined a few simple steps that will dramatically enhance the security of your website, email, and DNS by decoupling them.

Below are some tips and trick which will enhance the security of your email, website and DNS

How to Manage Your DNS

First is to manage your (DNS) domain name system through a service like CloudFlare. Their preliminary package is free and work very well, and theand they have other technologies that speed up your site around the world.

How to Manage Your Email

Second is to get a business-grade email service, such as Microsoft Exchange. Through Office 365, you can get Microsoft Exchange for only $5/month/user.

How to Host Your Website

If you have WordPress blog or website then it has to be hosted on the business hosting such as managed WordPress hosting as it is specially designed for WordPress however the other hosting plans may offer you more space and bandwidth but it can’t suffice your requirements.

Why You Want Redundancy

The decoupling of the service offer an incredible amount of redundancy. If suppose your website goes down it doesn’t affect your email and DNS as CloudFlare has so much redundancy and email exchange renowned in the market for its redundancy.

The Risk Is Real

If we give a though on the natural disaster at data center one could lose all of the data if the website, email and DNS is hosted on the same virtual dedicated server. If your server crashed you may lose entire data.

It Will Cost You…But It’s Worth It

The downside of this is cost. As of the time of publication, a typical bill for hosting all three services on a virtual server is about $500/year. The services I have outlined above would look like this:

Hosting: $5/month * 12 = $60

Exchange: $4/month * 50 users * 12 = $2,400

CloudFlare: Free tier

Total: $2,460/year

This price is significantly higher than the $500 but provides a lot of performance and risk mitigation. For example, if our website went down, as a digital marketing agency, it would be detrimental to our business. Email is a close second. Think of how many customers we would lose if our website was down for a few hours or even a full day! Who wants to work with a firm who doesn’t have a website that works?

Everyone Else Is Doing It

It is extremely rare, today, to find all of these services tied together on the same server. More and more, firms that are serious about protecting their online services, privacy, and intellectual property are decoupling these services and investing in a separate website, email, and DNS hosting services.
