What Is DDOS Attack And How To Protect Your Network From It

If you're a network admin, the DDOS attack is one of the worst things you ever wanna face in your personal network.DDOS means Distributed Denial Of Service and it is used to temporarily crash or shut down an online website or organization network. 

This method is famous among hackers as it makes a website unavailable to the intended users. This attack is also called as the Ping of Death as the main attack strategy is by pinging requests.

A DDOS attack is accomplished when a hacker tries to flood tremendous amount of requests to a particular website which is beyond the amount of traffic the site can handle, thereby overloading and finally crashing the server down.An attacker often uses more than 100 types of IP address to initiate a DDOS attack.A DDOS attack is different from a DOS attack where the attacks take place from one destination or source whereas in the case of DDOS the attack originates from multiple sources, i.e. different locations. 

This makes it especially difficult to stop the attack by blocking a single IP address as the flooding takes place from different destinations.

The scale of DDOS attacks has increased and as of 2016, it can send one terabyte per seconds worth requests.Usually, full-fledged DDOS attacks will crash a server within 20-30 min if the attacker has advanced equipment and a fast internet and it will take a minimum of 1-2 hrs to bring the server back online once shut down.
