DNS is the most popular protocol used for computer communication today, however with that it attracts deviant criminals who produce malicious attacks for illegal gain. One of the hottest trends in DDoS is the multi-vector attack, combining flood, application and state exhaustion attacks against infrastructure devices all in a single, sustained attack.
These vulnerabilities have put tremendous pressure on security experts lately, in bringing out effective defense solutions. These attacks could be implemented diversely with a variety of tools and codes. Topping the list of known major DNS attack types are:
Since there is not a single solution for Denial of Service, this attack has managed to prevail on the internet for nearly a decade. As a matter of fact:
TCPWave DNS, DHCP and IP Address Management (DDI) software provides all the traditional processes expected of a top rated DDI solution. However, when it comes to cybersecurity, TCPWave provides unsurpassed Cloud Management, Automation and Security using RESTful API’s and a proprietary secure transport built using 1024-bit encryption.
DNS is imperative for network operation and essential business operation in today’s marketplace. Because of this, DNS services are a prime target for attack to render a company’s networked resources and their virtual presence unreachable to the rest of the world. Even worse, if hackers could change the DNS records, then they could instead redirect everyone to sites they control. Since DNS is built upon cooperation between millions of servers and clients over insecure and unreliable protocols, it is uniquely vulnerable to disruption, subversion, and hijacking. Threat actors are utilizing many new techniques to disrupt businesses, including Generic Routing Encapsulation (GRE) based flood attacks and Connectionless Lightweight Directory Access Protocol (CLDAP) reflection techniques.
And to make matters worse, when Internet of Things (IoT) connected devices are left unsecured in an enterprise, they can act as pathways to penetrate business network defenses as well as become slave nodes themselves which are included in the DDoS traffic stream. For example, the Mirai botnet works by exploiting the weak security on many IoT devices finding victims by constantly scanning the internet for IoT devices that have factory default or hard-coded usernames and passwords. Detecting infected IoT gadgets is more difficult because, unlike PCs, an infected webcam or DVR doesn't show its owner any symptoms and, while simply rebooting a device will usually get rid of the Mirai malware, without a firmware update, it's still vulnerable to being re-infected.
