Abstract

A system and methods for mitigation slow HTTP, SSL/HTTPS, SMTP, and/or SIP attacks. A protection system monitors each TCP connection between a client and a server. The protection system monitors the header request time and minimum transfer rate for each client and TCP connection. If the client has not completed the data transfer in the minimum time or the data are not transferred at the minimum transfer rate, the protection system determines the connections are potentially a slow attack and resets the connections for the protected devices.
