Conditional Access And Identity Security

Identity is the new security perimeter in a cloud-first environment. Traditional network boundaries have diminished due to remote work and mobile access, placing greater emphasis on securing access based on identity and context.

Conditional Access is a key feature that enables dynamic, risk-based access decisions. It allows administrators to define policies based on conditions such as user location, device state, application used, and risk level.

For example:

• Require multi-factor authentication for users accessing from untrusted locations

• Block legacy authentication protocols for users with privileged roles

• Allow access only from compliant or domain-joined devices

The MS-900 exam includes this feature to emphasize adaptive security, where trust is continuously evaluated rather than assumed.

Multi-Factor Authentication And Password Policies

Passwords alone are no longer considered sufficient protection against identity theft. Multi-factor authentication adds a critical layer by requiring users to verify their identity through a second method such as a code, biometric, or device prompt.

Microsoft 365 supports several forms of multi-factor authentication including:

• One-time passcodes sent via SMS or app

• Biometric authentication through Windows Hello

• App-based notifications using an authenticator application

Alongside these, password policies can be enforced to manage complexity, expiration intervals, and lockout settings. These measures help reduce the attack surface by making it harder for unauthorized users to gain access even if a password is compromised.

Information Protection And Data Classification

Data is the most valuable asset in any organization. Microsoft 365 includes extensive capabilities to protect sensitive information through classification, labeling, and encryption. These features allow data to carry its protection with it, regardless of where it is stored or shared.
