Exam CAS-005 topic 1 question 89 discussion

Context-based authentication takes into account additional factors beyond just the password, such as the location, device, and user behavior, to determine whether access should be granted. In this case, it would be used alongside the hardware security key to enhance security by verifying the user's identity based on contextual factors, thereby preventing unauthorized access even if a password is stolen. The other models are less suitable for this specific issue: A. Rule-based focuses on predefined rules for access control but doesn't address the dynamic context of authentication. B. Time-based typically uses factors like time of day or session duration, but it's not directly linked to preventing unauthorized access due to stolen credentials. C. Role-based is concerned with access control based on the user's role within the organization, but it doesn't specifically address the risk of stolen passwords.
