DDoS protected DNS service: Who can benefit from it?

What does DDoS protected DNS service stand for?

DDoS protected DNS service is a robust network with servers strategically placed around the world. Servers are pretty adept at distributing the traffic loads. To be alert for any potential attacks. When there are noticeable traffic peaks, the load is divided across the servers in the network. More staff will remain employed by your company if an attacker successfully takes down a server instead of causing downtime.

DDoS attacks: what are they exactly?

A cyberattack known as a DDoS (Distributed Denial of Service) aims to bring down your website, network, or service. This is typically done by flooding your server with bandwidth until it crashes or using a DNS or protocol weakness, such as the UDP flaw, to triple the traffic to your website or service.

DDoS attacks can take many forms and frequently bring down significant firms like Amazon. As a result, you put yourself at serious risk if you don’t have enough protection. Any attack on one of your “neighbors” will also affect you if you use shared hosting.

DNS tunneling attack explained in detail

The purpose of DNS tunneling attack

DNS tunneling is a sort of Domain Name System attack, as the name implies. It employs a client-server mechanism to push malware across a tunnel. In addition, it is a black hat approach for establishing a covert conduit into a victim’s machine or network.

The channel constructed allows embedding a malicious payload within DNS queries, allowing attackers to take advantage of DNS traffic’s largely unconstrained flow—especially in settings where practically all other communication is controlled.

DNS load balancing benefits

DNS load balancing is a handy feature for load distribution. This method is used by an increasing number of businesses, both large and small. But how does it work, and what are the benefits? We’ll get to that later in the article.

DNS load balancing – what is the meaning?

To begin, we will define this method. As we already know, DNS is a system that connects a domain name to its IP address. A domain is stored on a single server by default. However, if your site receives a lot of traffic, this can cause it to crash. To prevent this, we use load balancing. To put it another way, this feature redirects DNS queries to multiple web services.

​Benefits from using a Secondary DNS service

​What is a Secondary DNS service?

A Secondary DNS service is an addition to your Primary DNS service that provides extra name servers that have a copy of the zone file. Those servers will store the DNS records for your domain and resolve the domain when someone queries them. That way, they provide redundancy, better performance, hand increase your domain availability.

Most popular DNS attack types.

All types of cyberattacks are threats to take seriously. But DNS attacks directed to hit your DNS (domain name system) are like lethal RIP bullets impacting your system. Your online business can be fully damaged!

​DNS cache poisoning.

DNS Cache Poisoning (DNS Spoofing) hits through the DNS resolver servers. They can temporarily save a copy of the DNS records related to domains in their cache memory. Those records get cached the time established in their time-to-live (TTL).

What does DNSSEC mean?

DNSSEC meaning

Domain Name Security Extensions (DNSSEC) is a great way to add an extra security layer to your domains. It is an advanced DNS feature, which attaches digital signature (DS) records to the DNS information. So, that way, it can establish the authenticity of the source domain name.

The purpose of which it is designed is to protect Internet users from falsified DNS data. An example of such a case can be a misleading or malicious address rather than the actual address you wanted to visit.

Once you enable DNSSEC, the DNS lookups will have to use a digital signature to prove that the origin of the site’s DNS is accurate. It is very helpful for preventing some types of attacks. In case the digital signature does not match, the browsers will not open the site.
