How to block legacy authentication protocols using Azure AD Conditional Access policy

While i was working with a customer and this was one of their needs, i decided to blog on how i deployed.

At first, what’s legacy authentication and why i need to block these protocols?

Legacy authentication is a term that refers to an authentication request made by:

Older Office clients that do not use modern authentication (for example, Office 2010 client)

Azure AD Domain Services

I hear over and over discussions about Windows Active Directory, Azure AD and Azure ADDS ( Active Directory Domain Services).

Is it the replacement of a traditional Windows Active Directory?

What is Azure Active Directory Domain Services?

Azure Active Directory Domain Services (Azure AD DS) provides managed domain services such as domain join, group policy, lightweight directory access protocol (LDAP), and Kerberos/NTLM authentication. You use these domain services without the need to deploy, manage, and patch domain controllers (DCs) in the cloud.

Integrate on-premises apps with Azure Active Directory Application proxy

What is Application Proxy?

Azure AD Application Proxy is a great tool for publishing internal applications without exposing your servers to the Internet. If your applications require authentication for users to access them, you can get Azure AD to handle all this for you.

Application Proxy includes both the Application Proxy service that runs in the cloud, and the Application Proxy connector that runs on an on-premises server. Azure AD, the Application Proxy service, and the Application Proxy connector work together to securely pass the user sign-in token from Azure AD to the web application. The proxy does not require you to open any inbound ports through your firewall, the proxy connector simply connects outbound to Azure and all traffic is routed through that connection.

MCT Virtual Event

On Sunday 5/4/2020 I had the pleasure to participate for the first time in a Virtual Event. In my Azure Active Directory presentation I talked about the basic concepts of Azure AD and the differences with the traditional On premise Active Directory.
