Questions derived from the CISSP – CISSP ISC2 Self-Test Software Practice Test. Objective: Physical (Environmental) SecuritySubObjective: Support the implementation and operation of operations/facility security Item Number: CISSP.8.4.18 Single Answer, Multiple Choice Which characteristic is NOT evaluated by the biometric system performing a hand geometry scan? Ridge endings Width of the hand Width of the fingers Length of the fingers Answer:A. Ridge endings Tutorial:A biometric system performing a hand geometry scan will not evaluate the ridge endings on fingers. Ridge endings and bifurcations on fingers are evaluated by a fingerprint scan biometric system and not by a hand geometry scan biometric system. A biometric system performing a hand geometry scan will identify characteristics, such as the shape of a person's hand and the length and width of the fingers and the hand, to authenticate a user. The system compares the attributes provided by a user to the reference records that were gathered during the enrollment phase. If the attributes match, the user is granted access. Hand geometry scan-based biometric systems can either use the mechanical or the image detection technique to authenticate user credentials. Both of the methods verify hand attributes of a user for authentication purposes. Reference:CISSP All-in-One Exam Guide, Chapter 4: Access Control, Hand Geometry, p. 134.
