1. Read about Common criteria and different EALs [1]. Understand the Protection Profiles and Security Targets. Discuss about the role CC plays to maintain and enhance the security of biometric systems and answer the question “What role does common criteria play in security evaluation of biometric systems and devices?”

2. FAR (False Acceptance Rate) is a measure for the security of a BB systems, whereas FRR (False Rejection Rate) is a measure for the usability of the system. Although both needs to be low, still they are contrary to each other. Do you agree? Explain using an example. Also how these measures help in making the system attack resistance?
