Which of the following attack involves overwhelming a server with traffic ?
Answer: C
The attack is a DDoS attack.
In a Distributed Denial of Service attack, many compromised machines, often a botnet, send a flood of requests or packets to a target at the same time. The server or its network link is overwhelmed and cannot serve genuine users. Because the traffic comes from thousands of sources, simply blocking one address does not stop it.
SQL injection inserts malicious SQL through input fields. A man-in-the-middle attack secretly intercepts or alters communication between two parties. A brute-force attack tries passwords or keys systematically. None of them works by flooding a server with traffic.
