Tutorial / Cram Notes
Principal Authentication Types:
- Password-based authentication: Traditional and most common form that requires a username and password.
- Multi-factor Authentication (MFA): Enhances security by requiring multiple forms of verification.
- Windows Hello for Business: Uses biometrics or a PIN as an alternative to passwords.
- Certificate-based authentication: Utilizes public key infrastructure (PKI) to verify users with certificates.
Other Authentication Techniques:
- OAuth and OpenID Connect (OIDC): Utilized for authentication and authorization in modern applications.
- FIDO2: An emerging standard that supports passwordless authentication.
Planning for Secure Authentication
Multi-factor Authentication (MFA)
MFA is a key authentication method that significantly reduces the risk of unauthorized access. Plan to implement MFA for all users, especially privileged accounts. Azure MFA can use something you know (password or PIN), something you have (a phone or hardware token), or something you are (biometrics).
MFA Methods:
- Microsoft Authenticator app (notification or code)
- SMS or voice call
- OATH hardware token
Passwordless Authentication
Passwordless methods include Windows Hello for Business, the Microsoft Authenticator app, or FIDO2 security keys. Planning for a passwordless strategy means evaluating the technical readiness of your organization’s devices and user habits.
Conditional Access Policies
Conditional Access policies are critical in defining how users are authenticated under specific conditions:
| Criteria | A Policy Might Include |
|---|---|
| User Role | Require MFA for administrators |
| Location | Block access from untrusted locations |
| Device | Grant access only from compliant devices |
| Risk | Require password change or MFA on risky sign-in |
Identity Protection and Risk Policies
Monitor sign-in risk events and automate responses to suspicious activities by defining risk policies. This may involve forcing password changes or requiring MFA when a user sign-in is deemed risky.
Hybrid Authentication
Many organizations have on-premises Active Directory (AD) and are moving to the cloud with Azure AD. You’ll need to plan for a hybrid identity environment using:
- Azure AD Connect: To synchronize on-premises AD accounts with Azure AD.
- Federation with AD FS: For organizations that require single sign-on (SSO) and have an existing on-premises federation infrastructure.
- Pass-through Authentication (PTA): Simple password validation for Azure AD services without storing passwords in the cloud.
Emergency Access
Plan for emergency access accounts that are not dependent on MFA in case the primary MFA service is unavailable. These accounts should have strong passwords and are only to be used during emergencies.
User Training and Adoption
Training is often the most overlooked aspect of an authentication plan. Users need to be educated on how to register for MFA, benefits of passwordless options, and recognizing phishing attempts that could compromise credentials.
Review and Monitoring
Set up ongoing review processes and monitoring through Azure AD Sign-Ins and Audit logs, and regularly review these records for any anomalies or necessary adjustments to your authentication strategies.
In conclusion, for the SC-300 exam, you need to be proficient in planning an authentication strategy that aligns with the principles of modern security practices, such as enforcing MFA and considering passwordless options. This should be backed by strong conditional access policies, risk assessments, and seamless integration with existing on-premises directories. Keeping these considerations in mind will not only help you with the exam but also in designing robust authentication systems for any organization.
