DDoS or the deaths on Defend' attack is a very common phenomenon in the world of Information Technology and Computer Security.
It is also a rather new attack and one that has not yet been fully exploited to its full capabilities, but as it does not have the same impact as more traditional attacks it is often under-utilized and therefore needs a more elaborate solution.
The former is initiated by a number of sources with the aim of saturating a single link or network with high bandwidth traffic in order to bring down a server or network of machines.
With this type of attack, the DDoS attacker can easily bring down a certain web server by saturating the targeted resource.
With the help of the right sniffer you can gain access to all the details pertaining to the originator of the attack and the destination of the attack - making sure that no further attacks will take place.
It has been observed that most IT departments don't actually have the kind of budget necessary for securing their servers against cyber attacks and when they do have the necessary budgets they often neglect their own safety.
