Enhancing Cybersecurity with Microsoft's Entra ID Protected Actions

In the ever-evolving world of cybersecurity, Microsoft Entra ID has taken a major leap forward with the introduction of "protected actions." This innovative feature is designed to secure Entra ID by mitigating the risks associated with unauthorized hard deletions of user accounts—a critical concern for organizations aiming to safeguard their identity infrastructure.

What Are Protected Actions?​

Protected actions serve as a robust security mechanism that integrates directly with Conditional Access policies. Traditionally, when an account is deleted within an Entra ID environment, it enters a "soft-deleted" state, remaining recoverable for 30 days. However, if an account is "hard-deleted," it becomes permanently unrecoverable. In many cyberattacks, attackers leverage permissions like User.DeleteRestore.All to exploit this vulnerability, potentially wiping out user accounts irreversibly.
By linking these sensitive operations to advanced Conditional Access policies, organizations can now enforce stricter authentication requirements. This means that any high-impact action, such as the deletion of a user account, mandates that users not only have the necessary privileges but also authenticate using robust, phishing-resistant methods.

How Do They Work in Practice?​

Conditional Access Integration​

The key to protected actions lies in their integration with Conditional Access policies. Here's a closer look at how this mechanism operates:

• Enhanced Authentication Context: Administrators can create policies that require additional verification steps before a protected action is executed. These policies can trigger advanced authentication methods—think passwordless solutions like FIDO2 keys or passkeys, and even phishing-resistant Multi-Factor Authentication (MFA).
• Policy Enforcement at Multiple Access Points: Whether the action is attempted through the Entra admin center, Microsoft Graph APIs, or PowerShell commands (e.g., using Remove-MgDirectoryDeletedItem), the Conditional Access policies ensure consistency and security across all platforms. This consolidation ensures that any attempt to hard-delete user accounts is subject to stringent security checks.
• Criteria-Based Permissions: For instance, a Conditional Access policy might require the user to be operating on a compliant device or to have activated a strong MFA solution before the deletion command is processed. This layered security strategy significantly reduces the risk of unauthorized deletions.

Testing Protected Actions​

Effective implementation of these policies is essential. As highlighted in recent insights, testing is pivotal—accounts with administrative privileges but equipped with weaker forms of authentication (like SMS-based MFA) should fail to execute protected actions if they do not meet the policy requirements. This granular control ensures that every potential vulnerability is covered, making it considerably harder for attackers to bypass security measures.

Strengthening Tenant Security with a Layered Approach​

Protected actions are an indispensable part of a broader security framework that champions the principles of Zero Trust Architecture and Least Privilege Access. While this mechanism doesn't render a tenant invincible—attackers who gain full control still pose a risk—it does add a formidable barrier against unauthorized high-risk operations. Here are some best practices to further safeguard your Entra ID environment:

• Employ Privileged Access Workstations (PAWs): These workstations are dedicated to sensitive administrative tasks, isolating them from everyday operations and reducing the attack surface.
• Maintain Emergency Accounts: Creating backup admin accounts that are excluded from Conditional Access policies can be a lifesaver in scenarios where regular accounts become locked out.
• Regular Audits and Monitoring: Keep a close eye on account lifecycle activities. Routine audits of permissions and unusual account activities can help in early detection of potential security breaches.
• Phasing Out Weak MFA Methods: Transition away from older, less secure methods like SMS-based authentication in favor of stronger, more reliable alternatives.

The Broader Implications for Windows Users​

For Windows system administrators and security professionals, these developments in Entra ID are significant. With organizations increasingly relying on identity as the primary gateway to access systems and data, ensuring that high-impact actions are protected against unauthorized execution becomes paramount. Establishing protected actions offers several advantages:

• Minimized Attack Surface: By complicating unauthorized deletion attempts, organizations can better protect critical system components from targeted cyberattacks.
• Increased Operational Integrity: Even if some defenses are breached, the additional layer of security helps maintain operational continuity by safeguarding account data.
• Streamlined Compliance: These measures can assist in meeting various compliance requirements by enforcing tighter controls on administrative access and operations.

Final Thoughts​

In a digital landscape filled with evolving threats, Microsoft's introduction of protected actions for Entra ID marks a critical step forward in the proactive defense of identity systems. This feature not only protects against the irreversible loss of user accounts but also reinforces a broader strategy centered on Zero Trust and the Principle of Least Privilege.
As Windows administrators continue to defend their networks, integrating such robust security measures is essential. Protected actions, combined with advanced Conditional Access policies, provide a safety net that deters even the most persistent attackers from causing irreparable damage.
