What is a DDoS Attack 2016?
A Distributed Denial of Service (DDoS) attack is an attempt to make an online service unavailable by overwhelming it with traffic from multiple sources. They target a wide variety of important resources, from banks to news websites, and present a major challenge to making sure people can publish and access important information.
Distributed denial-of-service attacks can paralyze even the most well-structured network for days, costing millions of dollars in lost sales, freezing online services and crippling a company's reputation.
Attackers build networks of infected computers, known as 'botnets', by spreading malicious software through emails, websites and social media. Once infected, these machines can be controlled remotely, without their owners' knowledge, and used like an army to launch an attack against any target. Some botnets are millions of machines strong.
DDoS attacks are destructive stealth weapons that can shutter a business. Our reliance on the Internet continues to grow, and the threat of DDoS attacks continues to expand. Organizations need to ensure operational continuity and resource availability with a vigilant DDoS mitigation approach if they want to conduct "business as usual."
DoS attacks are launched by individuals, businesses and even nation-states, each with their own particular motivation:
Hacktivism – Hacktivists use DoS attacks as a means to express their criticism of everything from governments and politicians, including “big business” and current events. If they disagree with you, your site is going to go down (a.k.a., “tango down”).
Less technically-savvy than other types of attackers, hactivists tend to use premade tools to wage assaults against their targets. Anonymous is perhaps one of the best known hacktivist groups. They’re responsible for the cyberattack in February 2015 against ISIS, following the latter’s terrorist attack against the Paris offices of Charlie Hebdo, as well as the attack against the Brazilian government and World Cup sponsors in June 2014.
