DDoS attacks mainly affect information, government or commercial sites, as well as server owners. Understanding the problem brings you one step closer to its quickest solution. Let's consider what a DDoS attack is, why and how it is carried out, and what consequences it entails.
What is DDoS
Distributed Denial of Service (DDoS) is a set of actions aimed at disabling a web hosting or server. It is impossible to carry out such an attack alone. Often, hackers prepare for this process in advance, it is not difficult to do.
The preparatory process involves distributing a on page seo service Trojan that infects unprotected computers. Then a network of infected devices and a coordinating server is created. When an attack is needed, the attacker sends a request to the coordinating server, which sends a signal to the associated computers to start sending malicious requests to the target of the attack.
What is the purpose?
There are several reasons for carrying out a DDoS attack, from the most trivial to the more advanced:
Entertainment is a banal reason and the easiest way to implement. Even a schoolchild can handle it, and often they are the ones who organize them. The most imperfect and open method is used, which causes minor failures in operation or an increase in ping.
Personal hostility is an attack on a resource for personal reasons. For example, if the user does not agree with the content provided, etc. The process is not difficult, both in implementation and in elimination.
Political protests are a more complex scheme aimed at expressing disagreement with the political situation in the country. This is often done by advanced hackers.
Competition – often seen on commercial sites when an unscrupulous competitor goes to extreme measures.
Extortion is used by fraudsters to extract money from potential victims.
How attacks are carried out and their consequences
The principle remains the same for all cases, but there are many ways, from the simplest to the most sophisticated. Let's look at the most popular ones:
HTTP GET and POST flood. The attacker simultaneously sends a powerful stream of requests to the server in order to overflow its resources. This leads to the fact that it completely stops responding to requests from real users or even to the server stopping altogether.
SYN. This attack involves launching a large number of TCP connections by sending a SYN packet with a false return address. It causes the server to crash.
