Deception Rules

Overview​

Deception strategies will be implemented as a deception rule. This rule is capable of generating and injecting deception data automatically into HTTP traffic. The goal of deception is to deceive and manipulate attackers inducing them to take actions that result in blocking the requests coming from them. The attacker should believe that fake parameters are genuine and really belong to the real application and should try to modify them in a malicious way.

The rule will have to do the following : Intercept HTTP responses of the original application and inject fake parameters before delivering the response to the client. The possible fake parameter values will try to have attractive names and values.

  1. For GET requests, the parameters will be added to existing <a href> link values.
  2. For POST requests, the parameters will be added as hidden input type parameters of existing forms.
