Introduction and Context
With the progressing cyber threats, ensuring the safety of user identities is always at the core of any robust security strategy. Azure AD B2C Identity Protection is enhancing security concerns by proactively detecting and investigating identity-related risks that could impact access to an organization. Through leading machine-learning technology and also Microsoft's worldwide threat intelligence, it equips organizations to tackle user identity challenges against malicious attacks and unsecured access.
The focus of this blog is going to be on the security provisions of Azure AD B2C Identity Protection from its licensing, features, pros and cons, and a critical role in risk management.
What Is Azure AD B2C Identity Protection?
Azure AD B2C Identity Protection is one of the security-focused determinants having the capability of real-time checks and evaluations of identity-based risks by detecting and also remediating those risks like attacks caused by malicious sign-ins, password spray attacks, and compromised accounts. Key features include:
Capabilities: What Identity Protection Offers for Security
-
Real-Time Risk Detection
Protects against brute force, password spray, and phishing attacks. Identifies atypical travel, anonymous IP usage, and malicious IP sign-ins.
-
Seamless Conditional Access Integration
Enforces security actions based on risk levels, such as MFA requirements or access denial.
-
Automated Risk Mitigation
Automatically resets passwords or disables compromised accounts. Reduces reliance on manual intervention for threat remediation.
-
Actionable Insights with Reporting
Risky Users Report: A dashboard of flagged users, aiding in investigating compromised accounts. Risk Detections Report: Detailed records of threat events to analyze the root cause of risks.
Licensing Requirements for Identity Protection
Azure AD B2C Identity Protection requires Azure AD Premium licenses, which are categorized into two tiers:
Premium P1
- Basic risk detection capabilities (limited insights but no detailed reporting).
- Conditional Access policies based on risk levels (e.g., enforcing MFA for risky sign-ins).
- Does NOT include Risky Users Report or Risk Detections Report.
Premium P2
- Full Identity Protection suite with automated risk-based remediation.
- Access to Risky Users Report (flagging compromised users).
- Access to Risk Detections Report (detailed threat analysis on sign-ins).
- User risk and sign-in risk scoring with automated mitigation (e.g., force password reset).
- Higher visibility into suspicious activity, including sign-ins from malware-infected devices.
Pricing Considerations
Azure AD B2C Identity Protection is included in Azure AD B2C Premium P1 and P2 tiers, but it is billed based on MAUs.
First 50,000 MAUs per month are free for Identity Protection in both P1 and P2 tiers.
After the free tier, pricing follows an incremental cost per MAU (Monthly Active User):
- P1 Features: ~$0.0028 per additional MAU beyond 50,000
- P2 Features: ~$0.0164 per additional MAU beyond 50,000
MFA via SMS/Voice incurs additional costs ($0.03 per attempt).
Why Use Identity Protection in Azure AD B2C?
Advantages
Disadvantages
Key Considerations for Implementation
-
Risk Evaluation and Mitigation
Use Risky Users Report to identify and address high-risk users proactively. Leverage Risk Detections Report (P2) to analyze specific threat patterns.
-
Conditional Access Policies
Design policies to enforce MFA or block access based on risk assessments. Tailor these policies to the sensitivity of your application data.
-
Integration with Security Tools
Export Identity Protection data into Microsoft Sentinel or Power BI for advanced analytics. Use Log Analytics to centralize risk data across applications.
-
Scalability
Plan for licensing costs as your user base grows. Assess the need for Premium P2 for high-risk industries like finance, healthcare, or e-commerce.
Gotchas and Potential Challenges
Regional Data Residency: Ensure Identity Protection insights comply with global data protection laws and data sovereignty requirements. Conditional Access Tuning: Fine-tune risk policies to avoid excessive security prompts or unnecessary user disruptions.
Why Identity Protection Is Critical for Security
During Migration
- Pre-Migration Mitigation: Identifies and addresses vulnerabilities in legacy user accounts before migration to Azure AD B2C.
- Baseline Security Establishment: Ensures a secure environment by proactively addressing compromised accounts.
Post-Migration
- Continuous Monitoring: Maintains a secure user experience post-migration by flagging risky accounts in real time.
- Data-Driven Decisions: Enables security teams to analyze risk patterns and adjust policies accordingly.
Conclusion
Identity Protection in Azure AD B2C is a cornerstone of modern identity security strategies. By detecting risks in real time, enabling automated remediation, and integrating seamlessly with Conditional Access, it offers robust protection for customer identities. While the licensing costs may pose challenges for smaller organizations, the benefits of improved security posture and user trust make it a worthwhile investment.
Whether you're planning a user migration or safeguarding your existing Azure AD B2C tenant, Identity Protection ensures that security remains at the forefront of your digital strategy. For organizations aiming to lead in customer trust and data security, it's an essential tool to deploy.
