Abstract
Attacks from automated scripts or processes, such as Web bots, can be dynamically blocked by monitoring dimensions of requests or submissions received by a system. Each host receiving requests can log information about the requests over a specified period of time. For each period of time, specified dimensions of the requests for that host can be analyzed to determine whether the number of requests having a common value for any of those dimensions meets or exceeds a specified threshold. If so, any requests having those specified dimension values can be automatically blocked for the next specified period of time. The requests can be automatically unblocked after that period of time if the requests do not again meet or exceed the threshold, but can be dynamically blocked for subsequent periods of time if the threshold is again met or exceeded.
