Security Best Practices: Using Time-Based Restrictions and Approvals for Activation of High Privilege Accounts

When engaging with our clients, security and the following best practices are always a top priority. A typical engagement always means that we use a dedicated client and project site in our Microsoft 365 (M365) tenant to collaborate with our clients and to share information in an efficient and streamlined fashion. We provide our clients with guest access using our Extranet User Manager product, to ensure that all project related information is readily available 24/7.

More often than not, our clients also provide us with access credentials into their Production M365 tenants with admin privileges, which begs the question: how do we use these elevated admin privileges only when absolutely necessary? Not only is this very important for us as an organization from a liability and compliance point of view, but this also helps to promote security best practices and minimize the risk for our clients.

Azure AD (AAD) Privileged Identity Management to the Rescue

Effective identity management of all users accessing resources on an organization's M365 platform is of paramount importance. System administrators must utilize all tools at their disposal to ensure that users have access to only the resources they need, when they need it. This is where AAD privileged identity management comes into the picture. Among its most important features is the ability to assign Azure AD roles to a particular account and to control the activation of these roles through an approval process that ensures admin are aware at all times of who has access to what and with what level of privileges.

The following is a Privileged Identity Management workflow example that illustrates the high-level workflow involved in requesting access for assigned account roles.
