What are DDoS Attacks?

Posted by freemexy on December 12th, 2019

DDoS attacks are Internet attacks that make it impossible to access targeted websites and services. Distributed denial-of-service (DDoS) attacks achieve this by overloading websites and online services with junk traffic. unblock websites

There are many types of DDoS attacks. Although DDoS attacks have definitive symptoms, they are still very difficult for us to identify because they are similar to that of a virus. For example, you get slow access to files, either locally or remotely, excessive amounts of spam emails or a long-term inability to access a particular website.
Different DDoS attack vectors target different components of a network connection. While almost all DDoS attacks overload a target device or network with traffic, attacks can be divided into three categories. An attacker may use one or more different attack vectors or go through attack vectors that may be based on countermeasures of the target. Below are details about the three common types of DDoS attacks:

Volumetric Attacks:

Volumetric Attacks attempt to create congestion by overloading all available bandwidth between the target and the larger Internet. They send massive amounts of data to the target. May it be an amplification or another means of creating massive traffic, such as requests from a botnet.

Protocol Attacks:

They primarily concentrate on exploiting a vulnerability in Layer 3 or Layer 4 of the OSI layer. TCP Syn Flood is the most common example of a protocol-based DDoS attack. A series of TCP SYN requests sent to a target can overwhelm the target and make it unresponsive.

Application Attacks:

These attacks address the level at which a server generates web pages and responds to HTTP requests. In addition, application-level attacks are often combined with other types of DDoS attacks that target not only applications but also the network and bandwidth.
