Teardrop Attack

What is a DDOS Attack?

Loss always walks alongside profit; likewise a coin has two sides. What am I trying to express? Well, the concept is, though there is improved technology and increased networking performance though distributed systems, there is a negative side of it. Hackers out there are not only aiming at stealing your money or changing some important details, they are also out there to disrupt the normal distributed services. They do this through the distributed denial of service attack.So, what is a ddos attack? Read no to discover.

This type of attack involves disrupting the normal functioning of a particular website. Distributed denial of service attack or DDOS attack in short is a well-planned and coordinated attack whose aim is to make a particular website absent for its regular visitors. In short it is unlike other forms of attack which is randomly sent to various personal computers to disrupt its normal operation. So, what is a ddos attack and how is DDOS executed?

The most common procedure of carrying out a DDOS attack is flooding requests to the particular website. The attacker creates a program that implements an instruction to apply for many requests from the particular website. Normal customer traffic is disrupted and thereby not getting any services. This will further reduce the income normally earned by the company website. To make it worse, it may cause the loss of customers indefinitely. The whole process will also reduce the performance of the website. The server will overwork when trying to process all the requests accorded to it.

DDOS attacks come in very many forms. This depends on the specific function they make as they reach a DNS server. The first type is the TCP connection attack, this attack uses the entire infrastructure used to connect to the server. These infrastructures include firewalls, load-balancers and such. Even powerful devices are taken down by this type of attack. The second type is volumetric attack which consumes the bandwidth of the targeted network. They simply cause a lot of jamming hence bringing down the performance.

The third attack is known as the fragmentation attack. This type of DDOS sends a huge traffic of UDP and TCP fragment to the directed network. The server cannot reassemble the fragment due to their large number hence failing to perform as required.
