DoS Attack

DoS stand for denial-of-service attack, a type of attack on a network that is designed to bring the network to its knees by flooding it with useless traffic.

DDoS Attack

DDoS stands for Distributed Denial of Service. It is an attack where multiple compromised systems which are usually infected with a Trojan are used to target a single system causing a Denial of Service (DoS) attack.

Dos Attacks Are Characterized As:

  • Attempts to flood a network
  • Attempts to disrupt connections between two computers
  • Attempts to prevent an individual from accessing a service or attempts to disrupt service to a specific system or person.

Hackers use DoS attacks to prevent legitimate uses of computer network resources. Those on the receiving end of a DoS attack may lose valuable resources, such as their e-mail services, Internet access or their Web server. Some DoS attacks may eat up all your bandwidth or even use up all of a system resource, such as server memory, for example.

Denial Of ServiceA DoS attack may very well appear to be legitimate traffic on the system or network, but differs in that the volume and frequency of the traffic will increase to unmanageable levels. An attack on a Web server, for example, would not be normal spurts of visitors, but rather a large barrage of hits in close proximity so the server cannot keep up with the sheer volume of page requests. On a mail server, hundreds of thousands of messages can be sent to the server in a short period of time where the server would normally only handle under a thousand messages in that same time period. The targeted server would most likely be brought to a halt from a DoS attack because it runs out of swap space, process space or network connections.

While DoS attacks do not usually result in information theft or any security loss for a company, they can cost an organization both time and money while their network services are down.

I once spoke an elite computer security person and asked how did it feel to finally be a guru?
He was a bit perplexed and said, it's hard to come to an understanding that I'm a computer security guru, only because there's so much I still don't know.
