If you are planning on implementing better DNS Protection then you should figure out exactly what it is you’d like the solution to do.
The abbreviation DNS means Domain Name System. It is a system that alters an easy to recognize domain name to a numeric IP address that is loaded so it can be found on the Internet – making DNS practically a contact list. When you enter a search for a title you are served up an identifying number.
After a URL is typed into a browser a DNS lookup is carried out to identify the unique IP address that allows the website to be shown. As your DNS server finds the correct IP address, it is loaded to your web browser and a link is created. This is a very simple process that happens in less than a single second.
Advantages of DNS Security
DNS security has advantages over other types of internet security such as:
- Filtering takes place before content is loaded. This means internet speed is not affected negatively and there is practically no latency..
- DNS filtering requires zero software installations or new hardware as filtering occurs in the cloud on the service vendor’s servers. All that is required to start filtering the internet is to change your DNS settings to direct to the service provider’s DNS servers
- A DNS filtering service will make your group safe from all recognized dangerous websites including those recognized as being used for phishing campaigns to steal personal details.
- DNS filtering allocates companies additional power to choose which types of content that can be accessed by employees.
DNS Protection Best Practices
So now that we’ve established that DNS is, more or less, a contact directory for the world wide web we can understand why cybercriminals focus on DNS to redirect users to their malicious web pages. This process is referred to as DNS hijacking.
DNS hacking attacks so as to target DNS response traffic in Denial of Service attacks. Thi snakes it very important for all businesses to use DNS protection. Security experts say that implementing three DNS protection best practices to stop these attacks:
- DNS security extensions
- DNS over TLS
- DNS over HTTPS
DNS security measures are in place during the DNS lookup phase of a web request, before any content is loaded by the web browser. The DNS does not distinguish the differences between real websites and those used for malicious purposes. Every webpage has an IP address, and the DNS will automatically deliver those addresses. DNS malware protection works by comparing the IP address with blacklists of known malicious or illegal web pages. If an IP address is on a blacklist it will not be loaded. With DNS malware protection created, the IP address will be spotted. However, if the website is known to be dangerous and appears on a blacklist, it will not be served.
