Give your domain name extra security

Give your domain name extra security

Protect your reputation and your customers

As the escalation in numbers of hacks shows, the internet is vulnerable to hackers who take control of domain names (www), for example to gather visitors’ login credentials (phishing) or to trick visitors into shopping at a fake online store (redirects).

Every organisation – both small and large – should be concerned about phishing attacks and false redirects. If your domain name is not adequately secured, the consequences could be serious, both for visitors to your website and for your reputation on the internet.

Luckily, it’s easy to improve domain name security. The DNSSEC (Domain Name System Security Extensions) service gives your domain name extra security, without the need for extra knowhow. Simply ask your provider to activate DNSSEC for your domain name.

Why should you use DNSSEC

Retain control of your website

DNSSEC is a security service available in the DNS (Domain Name System). The service was developed to prevent hackers from modifying the name server process (DNS) and taking control of a domain name.

DNSSEC can also be explained as a number of digital signatures (a range of signed codes) at each stage of the DNS process (from the root server to the domain name’s IP address) which are attached to data to ensure their validity. The technology does not encrypt data but can tell you whether the address you’re visiting is valid.

By choosing to add DNSSEC to your domain name, you can be sure that the right page is shown when using links to your website and when the direct URL is used. This secures your company and protects visitors to your website.

Stop the hackers – don’t run any risks

DNSSEC makes it quick and easy to tighten security and subsequently completely prevent phishing and false redirects of domain names. Therefore, DK Hostmaster urges everyone with a domain name to set up the service.

Hackers are particularly interested in manipulating DNS addresses of domain names with cash flow. These could be banks, popular webshops or websites that collect sensitive personal details such as public services.

Blogs, websites with company presentations and similar sites with no user access or online shopping may also be affected but are less vulnerable. However, you avoid the risk altogether if you use DNSSEC.

It’s so easy to protect your domain name

Adding DNSSEC to your domain name is simple. Contact your name server manager/provider (typically, where you registered your domain name) and ask them to activate DNSSEC for your domain name. That’s all you need to do. But you should be aware that not all providers currently support DNSSEC for .dk domain names.

How to manage DNSSEC on our self-service portal

DK Hostmaster recommends that you ask your provider to handle DNSSEC so that you don’t need to do anything yourself. However, if you wish to, you can manage DNSSEC via DK Hostmaster’s self-service portal. You will need to ask your provider to activate DNSSEC for your domain name.

To find this service, click on ‘Show more details’ next to the domain name.

Then, select ‘Manage DNSSEC’ further down the page. This gives you a number of options, for example to retrieve DNSSEC keys, add DNSSEC keys or deactivate the service if you no longer want it.

False redirects

A customer clicks on a link to a webshop. The link has been hacked and the customer is redirected to a fake webshop, for example a seller of replicas of the product the customer expected to find.
