Can Load balancing help against DDoS attacks?

Posted on      by      Leave a Comment on Can Load balancing help against DDoS attacks?

The Load balancing is a critical component for preventing DDoS attacks. Why? We will take a detailed look at that a bit later in this article. Let’s start.

What does Load balancing mean?

Load balancing in DNS is a way of dispersing client requests among server machines using domain configuration. The domain can be linked to a website, email system, or any other Internet-based service.

If you operate a large and popular website, you may expect a lot of requests for it. It must also be speedy, give up-to-date information, and accurately and rapidly handle the requests it receives. This is where the concept of traffic balancing comes into play.

Zone transfer – What is it, and why should you restrict it?

Posted on      by      Leave a Comment on Zone transfer – What is it, and why should you restrict it?

Zone transfer explained

Zone transfer is a fundamental process that serves for making a copy of the DNS data (DNS records) for a domain name from its Primary DNS zone to the Secondary DNS zones. The main advantage of such action is to make several copies of the collection of DNS records in more than one name server. Thanks to this approach, your domain name is going to have better availability.

Benefits of deploying DNSSEC.

Posted on      by      Leave a Comment on Benefits of deploying DNSSEC.

The existence of DNSSEC itself is already a big benefit. Without it, the Domain Name System (DNS) infrastructure would be absolutely vulnerable. Yes! No matter it’s the keystone for the whole Internet to work as you know it, security was not considered in its original design.

The explanation for this lack is easy. The DNS was created in the 1980s, and at that time, the Internet was considerably smaller. Then the “network of networks” grew exponentially, and the lack of authentication was clearly a problem. The Internet Engineering Task Force (IETF) experts in charge of the protocol standards knew it and worked on a solution (the 1990s). That’s how DNSSEC Security Extensions got born.

Here you will see working solutions against DNS poisoning attacks. Apply these steps and protect your business from the harmful effects they could have on it. 

​What is DNS poisoning?

DNS poisoning or DNS spoofing is a type of attack in which the bad actors manipulate the DNS traffic, usually by infecting the DNS cache and directing this traffic towards a fake website they control. The idea is that the visitors won’t know they are redirected to a site that bad actors manage because it will look just like the real site. There they can leave their private data that the criminals can use in the future.

What is Backup (Slave) DNS?

Posted on      by      Leave a Comment on What is Backup (Slave) DNS?

Backup DNS explained.

Backup DNS is also frequently called Slave DNS, and it holds a copy of all the information for a domain, including DNS records. That copy is received right away from the Master or Primary DNS. You are not able to perform any modification, and it acts only for storing the data. In case you desire to make some additional changes to the data, you should make them in the Primary DNS. Then they are going to propagate to the Slave DNS as well.
