Utilizing Microsoft Entra ID as a centralized identification administration system

Anybody who has struggled to handle a number of identification techniques understands that it’s an costly and inefficient strategy. Authorities clients who’ve adopted Microsoft Entra ID as their central company identification supplier (IdP) gained a holistic view of all customers and their entry permissions as required by the memo. Additionally they gained a centralized entry coverage engine that mixes indicators from a number of sources, together with identities and units, to detect anomalous person habits, assess threat, and make real-time entry selections that adhere to Zero Belief rules.

Furthermore, Microsoft Entra ID permits single sign-on (SSO) to sources and apps, together with apps from Microsoft and hundreds of different distributors, whether or not they’re on-premises or in Microsoft business or authorities clouds. When deployed because the central company IdP, Microsoft Entra ID additionally secures entry to sources in clouds from Amazon, Google, and Oracle.

Many authorities clients are facilitating safe collaboration amongst completely different organizations through the use of Microsoft Entra Exterior ID for business-to-business (B2B) collaboration to allow cross-cloud entry eventualities. They don’t have to offer collaboration companions separate credentials for accessing functions and paperwork of their surroundings, which reduces their cyberattack floor and spares their accomplice customers from sustaining a number of units of credentials for a number of identification techniques.

Utilizing Microsoft Entra ID to facilitate cross-organizational collaboration

Considered one of our authorities clients, together with their accomplice company, configured cross-tenant entry settings to belief multifactor authentication claims from every person’s residence tenant. Their accomplice company can now belief and implement robust phishing-resistant authentication for the client’s customers with out forcing them to sign up a number of instances to collaborate. The accomplice company additionally explicitly enforces, by means of a Conditional Entry authentication energy coverage, that the client’s customers should sign up utilizing a private identification verification (PIV) card or a typical entry card (CAC) earlier than gaining entry.

One other authorities buyer wanted to offer staff from completely different organizations throughout the identical company entry to shared companies functions akin to human sources techniques. They used Microsoft Entra Exterior ID for B2B collaboration together with cross-cloud settings to allow seamless and safe collaboration and useful resource sharing for all company staff, different authorities businesses (OGAs), and exterior companions. They used Microsoft Entra Conditional Entry coverage and cross-tenant entry settings to require that staff sign up utilizing phishing-resistant authentication earlier than accessing shared sources. Belief relationships make sure that this strategy works whether or not the house tenant of an worker is in an Azure business or authorities cloud. Additionally they enabled collaboration with businesses that use an IdP apart from Microsoft Entra ID by organising federation by means of the SAML 2.0 and WS-Fed protocols.
