What is DDOS / DNS attacks / cache poisoning?

A denial-of-service (DDoS) attack refers to attempts to overload a network or server with requests, rendering them unavailable to users. Many such denials of service are accidental, but malicious attacks occur as well. Cache poisoning refers to the corruption of a server’s domain name system (DNS) table, which redirects traffic to another (incorrect) address.
