A system and method for protection of Web based applications are described. The techniques described provide an enterprise wide approach to preventing attacks of Web based applications. Individual computer networks within the enterprise monitor network traffic to identify anomalous traffic. The anomalous traffic can be identified by comparing the traffic to a profile of acceptable user traffic when interacting with the application. The anomalous traffic, or security events, identified at the individual computer networks are communicated to a central security manager. The central security manager correlates the security events at the individual computer networks to determine if there is an enterprise wide security threat. The central security manager can then communicate instructions to the individual computer networks so as to provide an enterprise wide solution to the threat.
