Delays have Dangerous Ends: Slow HTTP/2 DoS attacks into the Wild and their Real-Time Detection using Event Sequence Analysis. (arXiv:2203.16796v1 [cs.CR])

The robustness principle, written by Jon Postel in an early version of TCP
implementation, states that the communicating entities should be liberal while
accepting the data. Several entities on the Internet do follow this principle.
For instance, in this work, we show that many popular web servers on the
