The Domain Name System (DNS) serves as a protocol for your domain to be translated into machine-friendly IP addresses - allowing your website to be properly routed to visitors' browsers.
Created in the 1980s, the DNS system was not made with security in mind and as a result is a prime target for a cocktail of attacks, including:
DNS Flood Attacks - When clusters of illegitimate traffic overwhelm your website's DNS server, your website is left compromised
DNS Spoofing - Through malicious altering of DNS records, hackers are able to redirect your website visitors to spoofed, look-a-like versions of your site - allowing for easy phishing of your customers' data
DNS Tunneling - By intercepting communications between your website visitors' browsers and your DNS Server, malware can easily be “tunneled” into customers' computers
DNS Hijacking - Through the hijacking of DNS queries to your site, legitimate web traffic can be rerouted to fraudulent DNS servers and look-a-like versions of your site
