Ensuring who is allowed to enter and view health information is the core idea. Strong authentication means requiring more than just a password—often a second factor like a token or a biometric check—so the person trying to access the system is truly who they claim to be. This layers security: even if a password is compromised, the attacker still needs the additional factor, making unauthorized access much harder. In health care, this supports accountability because each access can be tied to a verified user, and it aligns with safeguards intended to protect PHI. Storing data without encryption does not address who is accessing the data; it simply leaves data readable if access occurs. Frequent password sharing breaks identity verification and makes it impossible to know who accessed information. Ignoring access logs prevents detection of suspicious activity, letting breaches go unnoticed. Together, these options fail to reduce the risk of unauthorized entry the way strong authentication does, which fortifies the barrier to entry and strengthens traceability.
