What Is a DNS Attack?

First, what is a DNS? A DNS, or the domain name system, translates domain names that are readable by humans (i.e., www.espanol.optimum.com) to machine-readable IP addresses.

When a DNS attack occurs, the attacker corrupts a DNS server to redirect web traffic to a malicious website to collect personal information or initiate another attack. Attackers can do this by replacing a legitimate IP address in the server's cache with the IP of a rogue address.

Types of DNS Attacks

Cybercriminals use several DNS attacks to hack into your system. These are some of the most common types of DNS attacks.

• Domain hijacking changes your DNS servers and domain registrar, redirecting them from the original servers to new destinations.
• DNS flood attacks overload your server, preventing it from serving DNS requests.
• Distributed reflection denial of service (DRDoS) attacks overload your network with many bandwidth-consuming requests
• Cache poisoning involves injecting malicious data into your DNS resolvers’ cache to redirect Internet traffic. 
• DNS tunneling encodes the data of other programs or protocols in DNS queries and responses. 
• DNS hijack attack uses malware infections to hijack key system services. 

What Is a DDoS Attack?

DDoS attack means distributed denial-of-service attack. Here, cybercriminals attempt to jam up your website with a flood of Internet traffic, rendering it useless and disrupting regular traffic. Compromised computer systems are often the source of attack traffic.

Types of DDoS Attacks

Different types of DDoS attacks target different elements of your Internet network, and they are classified according to the network connection layers they target. Here are common DDoS attacks.

• Volume-based attacks, sometimes called volumetric attacks, aim to control all available bandwidth between their target and the Internet. 
• Protocol attacks aim to consume all available capacity of web servers or other resources, such as firewalls.
• Application-layer attacks occur when a server runs database queries to generate a web page, forcing the target’s server to handle more than it normally does.
