What is a Denial of Service attack?
A Denial of Service is a cyber-attack in which the attacker with malicious aim makes the machine or network resource unavailable to its intended users by flooding the target network with heavy traffic.
The DoS attacks typically exploited the security vulnerabilities present in the network or system. The victims of DoS attacks are often high-profile organizations such as banking, commerce, government, and trade organizations.
How does a DoS attack work?
Denial of service is typically achieved by overwhelming or flooding the targeted network with a huge amount of requests with a malicious attempt to overload the system and prevent some legitimate requests from being fulfilled.
