Abstract

Official abstract text for this publication.

According to one embodiment, a computing device is coupled to a set of web application layer attack detectors (AD), which are coupled between HTTP clients and web application servers. The computing device learns a new set of attribute values for a set of attribute identifiers for each of a sequence of rules through an iterative process having a plurality of iterations. The iterative process begins with an attack specific rule, and the sequence of rules includes an attacker specific rule and another attack specific rule. Each iteration includes receiving a current alert package from one of the ADs sent responsive to a set of packets carrying a web application layer request meeting a condition of a current rule used by the AD, automatically generating a new set of attribute values based upon the current alert package, and transmitting the new set of attribute values to the set of ADs.

First claim

Opening claim text (preview).

What is claimed is: 1. A method in a computing device communicatively coupled to a set of web application layer attack detectors (ADs), wherein the set of ADs are communicatively coupled between a set of one or more Hypertext Transfer Protocol (HTTP) clients and a set of one or more web application servers to protect the set of web application servers against web application layer attacks, and wherein each AD applies rules that each comprise a condition including a set of one or mo…
