Episode 76: Biometric Authentication Strengths and Weaknesses

Biometric authentication uses unique physical or behavioral traits—like fingerprints, facial features, or voice—to verify identity. In this episode, we explore how biometrics work, including the concepts of enrollment, matching algorithms, false acceptance rates (FAR), false rejection rates (FRR), and spoofing resistance. We also examine the strengths and weaknesses of different biometric systems, their privacy implications, and where they’re most effectively deployed. As biometric technologies continue to evolve and gain adoption, CISSPs must understand how to assess, implement, and monitor them securely and ethically.
