Distributed Denial of Service attacks are a way of cyber attack in which hackers use brute force attack, overloading networks with traffic. The network crashes hackers damage server and steal data. When a DDoS attack becomes successful, hackers can move in to modify programs as they wish, steal sensitive data such as credit card numbers and personal correspondence which is worth money as they use it to extort or steal money from legal holdings. All this necessitates DDoS Protection to be in place to stop such malicious attempts at cyber attacks.
DDoS Protection is necessary nowadays and its implementation in networks is a must. DDoS assaults can be classified in 3 types:
1. Volume Based Assaults
These assaults largely rely on auto generated bogus traffic/Spoofed Packets which is sent to servers in massive quantities. Server crashes because it cannot process it all. It is measured in bits per second.
2. Protocol Assaults
These assaults are initiated after careful study of target because it targets the weaknesses in a network, tearing it apart. Since they are completely new in nature, there are no counter measures for this. Also termed Day Zero Attacks. It is measured in packets per second.
3. Application Layer Assaults
These attacks send way too much network requests to the server and it is not equipped with enough resources to compute it all. Measured in requests per second.
Despite all of these dangerous attack types, there are DDoS Protection methods which can be integrated on networks to add security and protect from threat of DDoS attacks. Some DDoS Protection techniques are as below:
1. Volume Based DDoS Protection
This type of DDoS Protection sends data coming in globally to data filtering centers which are equipped with hardware and software to clean out bogus traffic, auto generated requests and bad data packets. When data has been cleansed, it is transferred back to the original network for processing. This DDoS Protection methods gives the network filtered data which is less in quantity and absent of any attack signature.
2. Protocol DDoS Protection
There are some data packets which seem completely normal in nature but these requests in reality have malicious coding in them. When it reaches their destination on the machine, they execute and cause errors and unwanted functions. DDoS Protection protocol handles such problems by denying bad requests entry onto machine. It incorporates better software checking techniques which are able to determine normal from bad requests. This DDoS Protection can also stop human and computer attempts at a network and take action accordingly.
DDoS attacks are initiated from many different computers and internet connections, making them very powerful. These resources generate automatically produced traffic which is bogus and has no real purpose. This is directed towards targeted networks and when their capacity to process data packets is overloaded; the server fails to respond and crashes. This necessitates that strong DDoS Protection to be in place at all times.
