Conditional access works robustly with any application configured for access with Azure Active Directory.įigure 2. These considerations are used to decide whether to (1) allow access, (2) deny access, or (3) control access with additional authentication challenges (e.g., multi-factor authentication), Terms of Use, or access restrictions. Considerations for access include user role, group membership, device health and compliance, mobile applications, location, and sign-in risk.

They combine (1) attested runtime signals about the security state of a Windows device and (2) the trustworthiness of the user session and identity to arrive at the strongest possible security posture.Ĭonditional access provides a set of policies that can be configured to control the circumstances in which users can access corporate resources. Conditional access and Azure Active Directory Identity Protection make dynamic access control decisions based on user, device, location, and session risk for every resource request. Azure Active Directory conditional access is the foundational building block of how customers can implement a Zero Trust network approach. Microsoft has a story and strategy around Zero Trust networking. To master the balance between security and productivity, security admins also need to factor in how a resource is being accessed. Access control policies that focus only on who can access a resource is not sufficient. Today, employees access their organization’s resources from anywhere using a variety of devices and apps. Zero Trust networking based on Azure AD conditional access Zero Trust networks protect corporate data and resources while ensuring that organizations can build a modern workplace using technologies that empower employees to be productive anytime, anywhere, any which way. The state of cyberattacks drives organizations to take the “assume breach” mindset, but this approach should not be limiting. Zero Trust is the next evolution in network security. A solution based on Zero Trust network, configured with the right policies around user and device trust, can help prevent stolen network credentials from being used to gain access to a network. In targeted and data breach attacks, attackers can compromise a single device within an organization, and then use the “hopping” method to move laterally across the network using stolen credentials. Gating access to resources using dynamic trust decisions allows an enterprise to enable access to certain assets from any device while restricting access to high-value assets on enterprise-managed and compliant devices. Basic components of a general Zero Trust network model Access proxy that utilizes the above signals to grant or deny access to an organizational resourceįigure 1.Policy evaluation service to determine if a user or device conforms to the policy set forth by security admins.Device directory to maintain a list of devices that have access to corporate resources, along with their corresponding device information (e.g., type of device, integrity etc.).Identity provider to keep track of users and user-related information.A general Zero Trust network model (Figure 1) typically comprises the following: Instead, Zero Trust architectures leverage device and user trust claims to gate access to organizational data and resources. Zero Trust networks eliminate the concept of trust based on network location within a perimeter. Networks that fail to evolve from traditional defenses are vulnerable to breaches: an attacker can compromise a single endpoint within the trusted boundary and then quickly expand foothold across the entire network. However, today’s increasingly mobile workforce, the migration towards public cloud services, and the adoption of Bring Your Own Device (BYOD) model make perimeter security controls irrelevant. Perimeter-based networks operate on the assumption that all systems within a network can be trusted. The traditional perimeter-based network defense is obsolete.
