How do DDoS attacks work?

In a DDoS attack, cybercriminals take advantage of normal behavior that occurs between network devices and servers, often targeting the networking devices that establish a connection to the internet. Therefore, attackers focus on the edge network devices (e.g., routers, switches), rather than individual servers.
