DoS attacks are those where the hackers flood a network or system with heavy traffic. The system or the network is crashed or shut down, and becomes inaccessible to the users. 

Mostly, the DoS attacks are carried out on the servers of companies in various industries, like banks, IT firms, eCommerce, government, media portals, etc. While DoS attacks don’t cause data loss or a financial breach, but it costs time and money to tackle such attacks. 

Types of DoS attack

DoS attacks are of two types: flooding and crashing.
