Which measurement or biometric factor do security administrators look for most in their chosen access control methods?

Low Crossover Error Rate values

Explanation:

Security administrators look mostly for low Crossover Error Rate (CER) values because the lower the crossover error rate the higher the accuracy of the biometric system.

Crossover Error Rate is the rate where the FRR (False Rejection Rate) and the FAR (False Acceptance Rate) are equal when sensitivity of a biometric system is configured.

FAR (False Acceptance Rate) is the rate at which a biometric system will mistakenly accept an access attempt by a user that do not have official permission or approval.

FRR (False Rejection Rate) is the rate at which a biometric system will mistakenly reject an access attempt by a user that do have official permission or approval.
