Get familiar with DNSSEC

The creation of the Domain Name System (DNS) was key to the Internet’s evolution and growth. It was created in 1983 and by 1986 it became an Internet standard. It came to life for making easier the use of the Internet. Thanks to DNS, users could use easy and memorable names to request their favorite domains, instead of typing hard strings of numbers (IP addresses) for the same purpose.

Currently, knowing the security threats that Internet can mean, it can be hard to believe that security for the DNS to operate was not a primary priority when it was designed. But almost four decades ago, the network of networks was quite smaller. Developers of course forecasted its growth, but it happened very fast. And with its success, the need of making it secure arose.

What is DNSSEC?

Domain name system security extensions or DNSSEC is a set of protocols used to protect the security of the DNS and offer a cryptographic solution for authenticating domains. Together, these protocols build a security layer to make lookups and communication (exchange) processes safe for Internet users.

DNSSEC verifies data and the authoritative server through a system that includes public and keys.

3 Common DNS attack types and How to Fight Them

Do you want to learn more about DNS attack types? If the answer is yes, you are in the right place. In this article today, we will explore the 3 common ones and how to fight them. But first, let’s explain what a DNS attack actually is.

What does a DNS attack mean?

DNS was designed to reply to queries correctly and efficiently, not questioning their intent. As a result, DNS has significant flaws and the potential to be used as a conduit for cyber-attacks. So, we can say that a DNS attack occurs when hackers take advantage of weaknesses in the Domain Name System (DNS).

How does DNS work?

What is DNS?

The DNS (Domain Name System) is a decentralized system with a strict hierarchical structure for naming devices and services on the Internet and private networks. It is an essential part of how today’s global connected network, the Internet, works. 

It is responsible for directing queries for a particular domain name, like, through all the nameservers of different levels that know where the imputed domain name is located. It helps us by answering our domain name queries with the IP address of the host (IPv4 or IPv6 or both).  

It also finds services, verifies them in different ways, links different domain names, points to servers, redirects, and, in general, makes our lives a lot easier when using the Internet.
