ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

The biometric system is granting access to an imposter, so it is incorrectly matching an unauthorized face to a valid user template. This is measured by the false acceptance rate (also called the false match rate). Lowering the FAR reduces the likelihood that a non-enrolled individual is accepted. The false rejection rate tracks how often genuine users are denied, which is not the primary problem here. Equal error rate is a composite point used to compare systems but does not directly target the observed failure. Enrollment time has no bearing on authentication accuracy.
