DDoS Attack: What is it and how to stay protected against it?

DDoS attack aims at bringing services down by bombarding them with so much traffic that their services and infrastructure are unable to handle it. In a Distributed Denial of Service (DDoS) attack, multiple compromised systems are used to target a server with a huge volume of traffic. Typically, a botnet formed of compromised computers sends huge traffic to a targeted server which causes unstable connections and service outages as the service could not handle all the requests. Volume-based attacks - Volume-based attacks include UDP floods, ICMP floods, and other spoofed-packet floods. This type of attack is measured in bits per second (Bps).
