Many hosts participate in a coordinated attack. They send an overwhelming number of transactions to the target site, effectively blocking real traffic. In some cases, the huge volume will CRASH the site's servers.

The following signs may suggest a DoS or DDoS attack: Irregular network performance with reduced speed Inability to access any website Certain websites turn out to be unavailable Monitoring and analysing network traffic is the most prominent way to identify and evaluate a DoS attack.

What is the difference between DoS and DDoS attack?

DoS (Denial of Service) and DDoS (Distributed Denial of Service) attacks are very similar, but also different methods of attack. A DoS attack involves flooding a host with malformed or large TCP/IP packets in order to shut down the computer, website, or server. The large number of connection requests in a short amount of time renders the server basically useless as it tries to fulfill all of the requests, slowing it to a standstill. This standstill renders the server's resources unusable, hence the name Denial of Service, as computer users can no longer use the services provided. A DDoS attack is like a DoS attack but with one major difference: multiple computers launch a DoS attack against a target all at the same time. DDoS attacks are able to be done thanks to botnets, which is a network of computers that a hacker has compromised and connected them together in order to make a pool of available resources and vantage points. Once the hacker gives the signal, all of the computers in the botnet launch a DoS attack against a specified target.
