In evaluating the importance of the stage to an attacker you should consider what gains they may achieve and to what extent failure represents an obstacle to further progress at that stage. In evaluating the importance of the stage to the system owner you should consider how serious vulnerabilities at this point might be and what further risks they could open up. The evaluation of each stage is worth 5 marks
