What does a DDoS attack mean?
Distributed Denial of Service, which is for short, called DDoS, is a cyber-attack. It’s performed to disrupt essential targets like a network, system, or server. That is achieved by overwhelming them with lots of traffic, which is coming from many devices. The word “distributed” refers to the many various sources that are used to achieve the attack. When the target is down, the DDoS attack is complete. The outcome is simply not allowing any user to access it.
The DDoS attack can be of several kinds. Techniques can modify, or they could be mixed and accomplish a stronger hit to the target. Overall, any DDoS attack operates by infecting devices. If there are more connected to the Internet, more of them are going to attack the victim. This happens even globally and from any kinds of compromised sources like computers, servers, IoT devices, wearables. The target is not able to handle the traffic. It becomes sluggish and eventually becomes completely drowned.
