Distributed denial-of-service (DDoS) attacks are always in top headlines worldwide, as they are plaguing websites in banks, and virtually of almost every organization having a prominent online presence. The main cause behind the proliferation of DDoS attacks is that there is a very low-cost that the attacker has to incur to put such attack in motion. Fortunately, today various prevention methods have been developed to tackle such attacks. Before delving further into understanding about the ways to prevent DDoS attack, let’s first understand what exactly a DDoS attack is!

 A DDoS (distributed denial-of-service) attack is an attempt made by attackers to make computers’ resources inaccessible to its anticipated user. In order to carry out a DDOS attack the attackers never uses their own system; rather they create a network of zombie computers often called as a “Botnet” – that is a hive of computers, to incapacitate a website or a web server.
