Microsoft Entra Conditional Access, or Conditional Access Policy, provides powerful capabilities to manage and restrict access, especially to external users. In this blog, we look at how to use a BLOCK Conditional Access Policy to prevent external users from accessing resources they should not see.
We cover:
1️⃣ What external users can do in your environment by default. 2️⃣ Why a BLOCK policy is essential to your security.
🔎 What can external users do by default?
When you invite or allow external users to collaborate through Azure AD, they often get more access than you might want, depending on the configuration. This means that, for example:
- Azure Portal: Be able to access certain resources as an administrator or via shared links.
- PowerShell: be able to access APIs via scripts or command-line tools.
While collaboration is essential, you want to limit unwanted access to protect your data and resources. 💡
🚧 Why a BLOCK Conditional Access Policy?
Remote users play an important role in collaboration, but they also pose risks when they gain access to critical systems. A properly set BLOCK Conditional Access Policy ensures that:
- External users cannot access management tools, such as the Azure Management Portal and PowerShell APIs.
- You can meet security guidelines by limiting access to what is strictly necessary.
- Management becomes easier because you can segment external access without impacting internal users.
✨ What are the benefits of this approach?
- Enhanced security: You minimize risk by blocking access to the Azure Management API.
- Control: You can control exactly who gets access and to which parts.
- Flexibility: External access is restricted without interfering with internal workflows.
🌟 Closure
By understanding the default behavior of remote users in Azure and deploying Conditional Access effectively, you will better protect your environment from unwanted access. A BLOCK Conditional Access Policy is a powerful and simple way to strengthen your security. 🔐 Do you also want an environment that is optimally secured with the right measures?
