using your security analyst perspective to counteract the adversarial mindset, how would you address the risks to the CIA that I have identified?

The technology I choose is biometric devices. Relating to accessibility, If someone is missing a finger or has a damaged finger and needs fingerprints, what should you do?

Regarding confidentiality, attackers have been able to bypass this technology even by stealing prints altogether. How to address all of these risks?

Please provide sources if you can.
