Distributed Denial of Service is basically paralysing the website to process requests from user by bombarding the victim’s server with other requests. The DDoS attacker makes an effort to block the users from accessing any significant information from the website by pulling down the network connection and even prevent from accessing online accounts, emails and relevant important sites. The service gets badly affected and can even doom a business creating tarring its name in the market.

Most Common methods of DDoS attack

DDoS attacks can be done in a number of ways which basically blocks the service of a website or email service. The most common methods of DDoS attacks have been highlighted below:
1. Overloading Servers with requests :
The most common DDoS attack is to overwhelm the website with information such that the server gets overloaded with requests and fails to process it further resulting in “denial of service”. When you type the link to your chosen site, it basically sends a request to that server to process the information and display the page. However, DDoS attacker overloads this server with requests and fails the user’s attempt. This is the most common notion of DDoS attack.
2. DDoS attack using email account
A DDoS attack can be performed via spam emails too by launching a similar attack on the victim’s email account. Every email account irrespective of company or private, has restricted storage that restricts the data fed in the account. The DDoS attacker has to simply send large files to the account which consumes this data limit and blocks the account from receiving any further mails thereby collapsing its service.

How can we create a DDoS attack?

DDoS attacks are illegal and can even lead to heavy economical charges and imprisonment. However, knowledge on the know-how about creation of DDoS attack is pretty significant to combat with it.
IP/TCP stack implementation weakness :
The TCP/IP implementation weakness is also referred to as the Ping of Death in which the attacker creates an IP packet that goes beyond standard 65,536 byte size. The attacker sends this packet to the target system. The recipient system collapses as soon as this TCP/IP system is received. However, periodic and consistent updating of software can help to prevent Ping of death.
Teardrop :
Teardrop is a direct attack on the system in which IP packet g=fragments are reassembled. A Teardrop attack overloads the server with IP fragments that result in overlapping offset fields. If the server reassembles all the fragments without disregarding the ones having overlapping offset fields, it will crash the system.
IP/TCP weakness :
SYN attack works by initiating an application session that sends a TCP synchronisation packet to another program. An acknowledgment is sent by the first program which leads to a handshake between them. This results in backlog overfilling which at one point of time blocks the system from acknowledging any other incoming sync requests. As a result, the service succumbs and leads to denial of service.
