-
Role-Based Access Control (RBAC)
RBAC defines user roles and assigns permissions to those roles, effectively controlling what actions each role can perform within an application. For example, a banking application might grant read-only access to account statements for regular users, while bank employees are granted additional permissions to initiate transactions or manage accounts. The principle of least privilege dictates that users should only have access to the minimum necessary information and functionality to perform their tasks. This limits the potential damage from accidental or malicious actions.
-
Conditional Access Policies
Conditional access policies enforce access restrictions based on specific conditions, such as device compliance status, network location, or user risk level. For instance, access to sensitive corporate applications might be restricted to devices that are managed by the organization and meet certain security requirements, such as having the latest operating system updates and antivirus software installed. Access could also be blocked from untrusted networks or from users exhibiting suspicious behavior, such as multiple failed login attempts. This dynamic approach adapts to changing circumstances, enhancing security beyond static access controls.
-
Multi-Factor Authentication (MFA) Enforcement
MFA requires users to provide multiple verification factors to gain access to an application, such as a password and a one-time code sent to a mobile device. This significantly reduces the risk of unauthorized access, even if one factor is compromised. For example, a healthcare application might require both a password and a biometric scan to access patient records. The added complexity of MFA makes it substantially more difficult for attackers to gain access, providing a robust layer of security.
