The DNS: what does it mean?
The technological revolution has made life easier in many areas of activity. It has come to bring about a real change in businesses. Indeed, the Domain Name System (DNS) is a technology that was created to facilitate fast communication with the Internet, in this case with e-mail addresses, IP addresses, smartphones, social networks, etc. However, it still presents significant threats of attacks on company data. Cybercriminals use it to attack company data. This is why it is often advisable to protect your DNS. But how can this be achieved?
What is the domain name system?
By definition, the DNS understood as the domain name system is an electronic mechanism that consists of searching a website on the internet. In other words, it is a system that is assigned a logical address, the domain name, to a physical address, the IP address. For example, with the DNS you can easily associate the name of a company with an IP address to find it easily on the internet.

It will be a matter of associating "www.friedtwothings.com" instead of "www. 152 .152.45" without having to enter a long IP address and access the appropriate website. Domain names and their IP addresses are unique and cannot be interleaved. Generally, authoritative servers and resolver or recursive servers are used.
What are the threats to DNS security?
There are several threats against the DNS server. These threats are even evolving over the years, as cybercriminals are always looking for ways to bypass the security features that are in place. There are DDoS attacks, so-called distributed denial of service attacks and DNS poisoning attacks. The purpose of the first attack is to overload the server in order to damage it and penetrate the holder's computer system. DNS poisoning attacks, as the name suggests, involve damaging the server and hacking into all the data.
