The type of solution that would suit the needs of a large corporation that wants to automate access based on where the request is coming from, who the user is, what device they are connecting with, and what time of day they are attempting this access is Network Access Control (NAC). NAC is a solution that enables the enforcement of security policies and rules on the network level, by controlling the access of devices and users to the network resources. NAC can automate access based on various factors, such as the location, identity, role, device type, device health, or time of the request. NAC can also perform functions such as authentication, authorization, auditing, remediation, or quarantine of the devices and users that attempt to access the network. Discretionary Access Control (DAC), Role Based Access Control (RBAC), and Mandatory Access Control (MAC) are not types of solutions, but types of access control models that define how the access rights or permissions are granted or denied to the subjects or objects. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 6: Communication and Network Security, page 737; Official (ISC)2 Guide to the CISSP CBK, Fifth Edition, Chapter 4: Communication and Network Security, page 517.
