Reliable identity and access management (IAM) models enable the deployment and use of applications and information with significantly greater protection than what traditional perimeter security provides. IAM ensures that authorized users have the appropriate access to appropriate information assets. The security solution has been around for a long time, in some shape or form, to help organizations limit access to sensitive information and critical systems.
Simply put, IAM in enterprise IT entails defining and managing roles and access privileges of individual network entities, including users and devices, to the different cloud and on-premise IT assets. Users, in this case, include customers, employees, consultants, and partners, while devices include computers, laptops, smartphones, network equipment, servers, and IoT sensors.
