Additional Resources. This means that it is impossible for traffic floods to overwhelm your server and the capacity of the StackPath system is such that it cant be forced out of action. The essential difference is that instead of being attacked from one location, the target is attacked from many locations at once. As the flood of bogus requests are processed, the server is overwhelmed, which causes it to slow and, at times, crashat which point, access by legitimate users is disrupted. What is a denial of service attack (DoS) ? The IoT-connected devices include any appliance with built-in computing and networking capacity, and all too often, these devices are not designed with security in mind. Crypto mining is a common use of these bots for nefarious purposes.
