Defend against volumetric attacks, exploits, DNS hijacking and DNS-based data exfiltration with unique behavioural analytics.
The DNS protocol can be exploited easily. It is easy to craft DNS queries that can cause the DNS server to crash or respond with a much amplified response that can congest the bandwidth. The queries can be spoofed which means attackers can direct huge amounts of traffic to its victim with the help of unsuspecting accomplices.(open resolvers on the internet).
Traditional protection like firewalls leave port 53 open and don’t do much in terms of preventing DNS attacks. All these reasons make the DNS an ideal attack target.
