What does ddos mean?

DDOS full name is DistributedDenialofservice (Distributed Denial of Service), commonly known as flood attack. A lot of DOS attack sources together to attack a server is composed of a DDOS attack, DDOS can be traced back to 1996 initially, in China in 2002 began to appear frequently, in 2003 has begun to take shape.

DDoS attacks are a class of attacks based on traditional DoS attacks. A single DoS attack is generally used in a one-to-one manner, when the target of the attack is low CPU speed, small memory or network bandwidth and other performance indicators are not high its effect is obvious.

With the development of computer and network technology, the computer's processing power grows rapidly, the memory is greatly increased, but also the emergence of gigabit-level network, which makes the degree of difficulty of the DoS attack increased - the target of the malicious packet of attacks on the "digestive capacity" to strengthen a lot.

For example, your attack software can send 3,000 packets per second, but my host and network bandwidth can handle 10,000 packets per second, which makes the attack ineffective.

This is where distributed denial-of-service (DDoS) attacks come into play. DoS attacks are simple if you understand them.

If the processing power of computers and networks has increased by a factor of 10, and an attack with one attacker no longer works, what about an attacker using 10 attackers at the same time? What about using 100?DDoS is all about using more puppet machines to launch an attack, attacking victims on a larger scale than ever before.
