Access control systems are complex and can be challenging to manage in dynamic IT environments that involve on-premises systems and cloud services. One solution to this problem is strict monitoring and reporting on who has access to protected resources so, when a change occurs, it can be immediately identified and access control lists and permissions can be updated to reflect the change. Only those that have had their identity verified can access company data through an access control gateway. The reality of data spread across cloud service providers and SaaS applications and connected to the traditional network perimeter dictate the need to orchestrate a secure solution, he notes. In DAC models, every object in a protected system has an owner, and owners grant access to users at their discretion. If a reporting or monitoring application is difficult to use, the reporting may be compromised due to an employee mistake, which would result in a security gap because an important permissions change or security vulnerability went unreported. Some examples of At a high level, access control policies are enforced through a mechanism that translates a users access request, often in terms of a structure that a system provides.
