The rise of hacktivism in recent years has led to an onslaught of distributed denial-of-service (DDoS) attacks. In response, organizations and web hosts are putting solutions in place to combat these types of hacks. But how well are these solutions working, in terms of effectively stopping DDoS attacks?

A DDoS attack is an attempt to make a system or network resource unavailable to its employees or customers. The methods for carrying out a DDoS attack can vary, but they typically consist of efforts to temporarily or indefinitely interrupt services of a host system that’s connected to the Internet.

DDoS attacks are sent by two or more individuals or bots, whereas denial-of-service (DoS) attacks are instigated by one person or system. In many cases, DDoS attacks are launched against sites or services that are hosted on high-profile web servers. More recently, the attacks have also been used as a form of political resistance or social justice protest.
