In this way, the authentication request will be start with Azure Active directory, which simply means that most of Azure security features can be applied to this kind of access such as conditional access and MFA. MS Exchange published over Azure APP proxy:Īzure Application proxy is new way to publish your web-based application over internet securely. Application Proxy doesn’t require you to open inbound connections through your firewall which make it very secure to publish your on-premises applications in a very secure manner including Exchange OWA. Note: anything applied in OWA will be by default applied to EAC access, in below article we only focusing in OWA, this is also applied for EAC by default without mention it explicitly.
#Exchange on azure vs office 365 windows#
This article will focus in two main components, OWA Authentication access and Outlook for windows MAC and Outlook for mobile Access since there are the two major ways for end users to access their mailboxes. Multi -Factor Authentication can be used in multiple scenarios, each scenario needs specific implementation that can help to protect on-premises environment, typically in this article we will focus on Exchange on-premises where customers still not using Exchange online.Īzure offering a lot of ways to protect Exchange components, each scenario has pros and cons, in this article we will go through all options that we currently have. Something you have (a trusted device that is not easily duplicated, like a phone).Something you know (typically a password).
It works by requiring two or more of the following authentication methods: It is useless without having possession of the additional authentication method. Security is a big trend these days, Azure Multi-factor authentication (MFA) is one of the Microsoft security solutions which can be used as a second layer of authentication, the simple idea of MFA is to prevent an attacker from gaining access even if they manage to learn the user’s password. This raises a big concern regards the security, how we can prevent such unauthorized access to the data even if the credentials where stolen using any kind of attacks. In this article I will be discussing a very interesting topic where we see a lot of confusion when customers are looking to implement a solution to protect their exchange on-premises environment with Azure MFA.Ĭurrent traditional Exchange deployment allows the users to access their mailboxes using their traditional credentials (Username and password), in such deployment if any bad guys were able to know these credentials then it will be very easy for them to access the customer data. In this series, we will start discussing how customers can utilize Azure AD to protect their environment, Azure AD offering a lot of security features that can be utilized, hence with the time we will keep listing our customer challenges and how Azure AD can help to solve them.
