Internet is built for providing huge resources to its users and positively sharing the available resources among its users. It is not built with security in mind in the beginning and hence opened doors for many kinds of abuse by malicious users. Any website with few or many web pages can be DDoSed to disable the web servers from serving legitimate users. Interestingly, some web servers are almost unaffected or affected but not manifested through these attacks, therefore these kinds of websites need not plan for and deploy DDoS protection mechanisms in reality. When the attackers’ attempts do not affect the good intended outcomes, the problem can be considered to be trivial. We devised a framework namely “DDoS Protection Necessity Index (DPNI)” for evaluating the need of DDoS defense for different categories of websites on the Internet. This framework is deemed to be reliable and effective.

Internet, DDoS Attacks, Flash Crowds (FCs), Load Testing, Hyper Text Transfer Protocol (HTTP), Attack Impact, DDoS Protection Vendors (DPVs).
