Abstract
A method, non-transitory computer readable medium, security management apparatus, and network traffic management system that monitors received HTTP requests associated with a source IP address to obtain data for one or more signals. A value for one or more bins corresponding to one or more of the signals for individual behavioral histograms and a global behavioral histogram is updated based on the signal data. The individual behavioral histograms each correspond to one of the source IP addresses. A determination is made when a DDoS attack condition is detected. When the determining indicates that the DDoS attack condition is detected, an attack pattern is identified in the global behavioral histogram and a mitigation action is initiated for one of the source IP addresses based on a correlation of one of the individual behavioral histograms, which corresponds to the one of the source IP addresses, to the attack pattern.
