Microsoft Security, Compliance, and Identity Fundamentals SC-900 Practice Question
Your company decides to enforce multifactor authentication (MFA) for all employees to reduce the risk of account compromise. According to Microsoft's defense-in-depth model, which security layer is primarily strengthened by this action?
Multifactor authentication is a control that verifies user identities before granting access to resources. In Microsoft's defense-in-depth model, such controls belong to the Identity and access layer. Perimeter and Network layers protect traffic flow, while the Data layer safeguards the information itself; none of these layers are primarily focused on confirming who the user is.
