A DDoS Attack or a Distributed Denial of Service is a huge attack targeting a specific server or a network of machines. This type of attack originated in the early 90s, when the severity was low.
In the late 90’s or 2000’s the first real distributed DDoS attack happened. During those days, Trinoo was the popular tool to execute such an attack. In the initial days of DDoS attacks, a series of computers were infected. These infected computers received commands from a central location which was also known as botnet C&C (Command and Control). But this system was easily traceable and the attacks could be prevented on time. So, the attackers devised a new way. Instead of attacking from a single host they used IRC (Internet Relay Chat). In this new variety, all the infected machines were connected via a port and host name using a botnet code. The attackers needed a single chat entry and their attack was seen by thousands of infected computers.
Widespread Fear of DDoS
DDoS attacks caused the first real stir when the search giants Yahoo were taken down. This attack
happened in early 2000’s when the bandwidth required for such an attack would have been immense. But the fear of DDoS spread among Internet users when Spamhaus was taken down. CloudFlare (a leading content delivery network) analyzed and publicized the attacks vastly. CloudFlare informed the business owners how devastating a network attack such as DDoS could be. When people knew about the severity and vast reach of the attacks they were bound to be afraid.
How these Attacks Happen‘?
DDoS causes Denial of Service for the users or end users of what is being attacked. There are some ways in which DDoS attacks can be brought about. Three most common processes are mentioned below:
- In this process the connections for the targetted user is saturated. It prevents all other users from connecting to the network. Such an attack can be brought about with the use of UDP Flood and UDP Reflection Flood.
- The second process sends more packets per second than the router or host machine can handle. When the host machine becomes incapable of processing the requests the users‘ requests cannot be met. Such an attack is generally brought about by Synflood.
- Overloading the application with excessive requests is the third process of DDoS attacks. The attackers create a situation where there are thousands of users sending requests at the same time. When there are so many requests to handle the application is bound to crash. This attack is very potent nowadays, as most websites run on their databases. The attack overloads the databases and web servers.
How to Protect Yourself‘?
There are many services available in the market which helps businesses in ddos protection . These DdoS protection services can be installed with any hosting provider. They are easy to install and maintain.
DdoS mitigation services look to pacify the common causes of DDoS attacks such as TCP SYN Flood, UDP Flood, ICMP Flood, etc. These are reliable ways to protect your business from a loss of millions. Anti DDoS server installations can keep your information protected and provide reat uptime to a website. If you own a website, then these DDoS protection are perfect solutions for you.
