Distributed Denial of Service, or DDoS is a cyber attack that makes a network, server, or a website unavailable by flooding it with traffic from multiple sources at the same time. In a DDoS attack, a large number of compromised devices or bots are used to flood the target system with traffic, disrupting its ability to function properly. This attack can result in serious consequences such as lost revenue, damaged reputation, and compromised security.
In the second chapter of Knowledge Ketchup at Gurzu, Engineer Aadit Shrestha talked briefly about DDoS attack.
