DDoS- A Biggest Security Threat to Cyber World

Since the release of WikiLeaks cables on the internet, many websites are subject to DDoS attacks; these include attacks on the most popular websites such as Visa, MasterCard and PayPal which denied services to WikiLeaks website. Also recently Pakistan and India were engaged in a serious web battle where the Indian hackers have attacked Pakistan's Oil & Gas Ministry website and in retaliation Pakistan Cyber Vandals have targeted Indian websites including its prime CBI website which is hosted in one of India’s securest servers.

So we all want to know more about DDoS attacks that what exactly these attacks are and how it affects the security of websites worldwide. A distributed denial-of-service (DDoS) attack is an attack in which multitude of compromised systems attack a single target for example a website, and this flooding of traffic force the victim’s website to shut down thereby denying the services to legitimate users.

Many websites have faced the brunch of these attacks which have really shaken the security of World Wide Web. While these attacks have caused some material damage to their targets, these alone seem to be a poor indicator of "violence" causing congestion to the networking infrastructure and come under the acts of civil disobedience.

These attacks begin by exploiting the vulnerabilities of one computer system that intrudes, identifies and communicates with other computer systems that can be compromised and finally within matter of few minutes an intruder can call for a massive attack on one of its specified target forcing the victim’s system to shutdown. The worst part here is the usage of other compromised computer systems that doesn’t even get the idea that they have been used to shut down a specific target.

Anti-DDoS mitigation experts Blockdos protect websites and other online infrastructure from all type of DDoS attacks, their deep packet inspection engine and comprehensive application-layer intelligence efficiently deters all application traffic violations.
