DNSSEC is the best way of protecting your Domain Name System. In this article, we will show up why, what the term means, and where you can take advantage of it. So, let’s start.

What is the meaning behind DNSSEC?

The DNSSEC acronym stands for Domain Name System Security Extensions. It’s a collection of diverse security techniques that give DNS data with cryptographic authentication. It shows that the DNS data hasn’t been tampered with, but it doesn’t encrypt the DNS records. Instead, it functions as a trust chain, allowing each step of a query to be verified.

Definition of DNS tunneling attack

DNS tunneling attack is a type of cybercrime. The goal is a domain name system attack, as maybe its name suggests. So, it operates in a straightforward manner. However, DNS requests and responses frequently contain malicious material that is encoded by other programs or protocols. This provides an unnoticed command and control channel for attackers as well as a means of data theft.

Stages of a DNS tunneling attack

The stages of a DNS tunneling attack are as follows:

1. A hacker registers a domain and directs it to a server that belongs to him. Then it has the malware for tunneling installed on it.

2. The hacker infects the device with malware, breaks through the victim’s firewall, and abducts the affected device or the entire network.

The DNS directory is distributed globally and operates on a daily basis, assisting in the search and reach of millions of existing domain names.

Anycast DNS is a fantastic service that might benefit your company. It allows you to surf the web considerably more quickly and efficiently. So, let’s dig a little deeper into that.

What does Anycast DNS mean?

Anycast DNS is a routing mechanism that employs a simple trick: all instances have the same IP address. Therefore, you’ll have a network of Anycast DNS servers with the same IP address if you use it. Yes, this is doable, and there is no difficulty with the network. The benefit is that anybody who searches your domain name will obtain the same IP address, regardless of where they are in the world. The request will then proceed to this IP address, and because it is the same IP address, it will receive a response from the nearest Anycast DNS server. This saves time and ensures redundancy since if one server goes down, the request will travel a little further and receive a response from the next Anycast DNS server on the network.
