Tutorial / Cram Notes
Sign-in risk policies are a crucial component of securing access to applications and services in an organization, especially when dealing with Azure Active Directory (Azure AD). Implementing a sign-in risk policy involves identifying potential risks associated with a user sign-in action and responding to those risks with appropriate controls.
When a user attempts to sign in, Azure AD evaluates the sign-in attempt based upon various signals. These signals include the user’s credentials, the location from which the sign-in attempt is made, the device being used, and whether there is evidence of the sign-in attempt being part of a phishing attack or originating from a network identified as containing threats.
Using this information, Azure AD assigns a risk level—ranging from Low to High—to the sign-in attempt. The organization’s sign-in risk policy can then enforce certain actions based upon this risk level.
Sign-in Risk Policy Configuration
To implement a sign-in risk policy, you typically need to follow these steps:
- Access Azure portal: Navigate to the Azure portal and find the Azure AD identity protection section.
- Define user risk policy: Go to the ‘Sign-in risk policy’ under Azure AD Identity Protection.
- Set risk levels: Define which risk levels (Low, Medium, High) will trigger the policy.
- Choose controls: Decide on the controls to enforce for those risk levels, such as requiring MFA, blocking access, or allowing access without additional controls.
- Assign the policy: Determine the users or groups to which the policy will apply.
- Enable the policy: Save and enable the policy.
Example 1: Requiring MFA for Medium and High Sign-in Risks
- Description of Policy: Users will be required to perform multi-factor authentication (MFA) if their sign-in is deemed Medium or High risk.
- Risk Levels: Medium, High
- Controls: Require MFA
- Assigned to: All Users
Example 2: Blocking Sign-ins for High Risk
- Description of Policy: Prevent any sign-in attempts classified as High risk.
- Risk Levels: High
- Controls: Block access
- Assigned to: Selected user groups (e.g., sensitive or privileged accounts)
Managing Sign-in Risk Policy
Ongoing management of a sign-in risk policy is critical due to the evolving nature of threats. Here are some best practices for policy management:
- Review and Update Policies Regularly: As the security landscape changes, it’s important to routinely review the sign-in risk policies to ensure they reflect the current risk tolerance of the organization.
- Monitor and Investigate Alerts: Use the security reports in Azure AD to monitor sign-in attempts and investigate any alerts that are triggered by the risk policies.
- Educate Users: Inform users about the importance of sign-in risk policies and the potential actions they may experience, such as MFA prompts or blocked sign-ins.
- Simulate Risk Events: To ensure policies work as expected, perform controlled tests simulating different risk levels.
Reporting and Analytics
Keeping track of sign-in activities and understanding the impact of the sign-in risk policy, Azure AD provides detailed reporting and analytics. This includes information such as:
- Sign-In Logs: Detailed logs show the sign-in attempts and the risk level associated with each sign-in.
- Risk Detection Reports: These reports identify potentially risky sign-ins and can help in understanding the patterns that are leading to higher sign-in risks.
- Policy Impact Analysis: Before enforcing a new policy, Azure AD can simulate the impact on users to better understand the effects of the policy.
Comparative Table
| Risk Level | MFA Requirement | Access Block | Applies To |
|---|---|---|---|
| Low | Optional | No | All users |
| Medium | Required | No | All users |
| High | Required | Optional | Selected user groups |
Implementing and managing sign-in risk policy effectively enhances the security posture of an organization by ensuring that actions are taken based on the calculated risks associated with user sign-ins. With Azure AD’s robust set of tools and reports, administrators can tailor the user’s sign-in experience to maintain security without compromising usability.
Practice Test with Explanation
Sign-in risk policies in Azure AD can be enforced without having Azure AD Premium licenses.
- False
Sign-in risk policies are a feature of Azure Active Directory Identity Protection, which requires Azure AD Premium P2 licenses.
What do sign-in risk policies help with?
- A. Detecting sign-ins from infected devices
- B. Assigning group memberships automatically
- C. Detecting sign-ins from unfamiliar locations
- D. Detecting sign-ins from anonymous IP addresses
Answer: A, C, D
Sign-in risk policies help detect potentially malicious sign-ins based on sign-ins from infected devices, unfamiliar locations, and anonymous IP addresses.
Azure AD sign-in risk policies can block access entirely for risky sign-ins.
- True
Azure AD sign-in risk policies can be configured to block access entirely when a risky sign-in is detected or to enforce additional security measures like requiring MFA.
Azure AD Identity Protection only allows for static policies and does not support dynamic risk evaluations.
- False
Azure AD Identity Protection supports dynamic risk evaluation and adaptive policies that can adjust based on the context of the sign-in attempt.
What can be used to mitigate risks detected by sign-in risk policies?
- A. Multi-factor Authentication
- B. Password reset
- C. Assigning a new manager
- D. Reducing session timeout
Answer: A
When a sign-in risk policy identifies a risky sign-in attempt, one of the possible mitigations is to require Multi-factor Authentication from the user to prove their identity.
Conditional Access Policies and Sign-in Risk Policies are essentially the same in Azure AD.
- False
Conditional Access Policies and Sign-in Risk Policies are related but distinct features. Conditional Access Policies are broader and can use sign-in risk as one of their conditions, while Sign-in Risk Policies specifically focus on the risk associated with the sign-in event.
Sign-in risk policies only apply to user accounts and not to service principals or managed identities.
- True
Sign-in risk policies are designed to assess the risk level of sign-ins performed by user accounts and do not apply to service principals or managed identities.
When configuring sign-in risk policies, what levels of risk can you define to trigger specific actions?
- A. Low
- B. Moderate
- C. High
- D. No risk
Answer: A, B, C
Sign-in risk levels that can be configured in policies include Low, Moderate, and High. Actions can be defined to trigger at each of these levels.
The ability to simulate sign-in risk policies without enforcing them is possible with which feature?
- A. Azure AD Conditional Access
- B. Azure AD Identity Protection simulation mode
- C. Azure AD Security Defaults
- D. Azure AD Privileged Identity Management
Answer: B
Azure AD Identity Protection has a simulation mode (report-only mode) that allows administrators to understand the impact of sign-in risk policies without actually enforcing them.
Sign-in risk policies can be integrated with other Microsoft security products, such as Microsoft Defender for Identity.
- True
Azure AD sign-in risk policies can integrate with other Microsoft security products, enhancing security by sharing signals and automating responses across services.
