Overarching term for 'authentication' and 'authorization'?

According to CISSP study guide , access control include IAAA (Identification, Authentication, Authorization and Accountability).

So if you dont care about the rest then you can call Authentication and Authorization as Access control.

Where:

Identification : User_Name

Authentication : User_Name + Password ( in one factor auth , simple case)

Authorization : Access to resources once authenticated

Accounting : Tracking who did what

I would say the closest thing I can think of is Authentication, Authorization, and Accounting framework, often abbreviated to AAA.

Authentication, authorization, and accounting (AAA) is a term for a framework for intelligently controlling access to computer resources, enforcing policies, auditing usage, and providing the information necessary to bill for services. These combined processes are considered important for effective network management and security.

The only term that springs to mind as governing both is 'Access Management' With that I mean a system that implements Authentication, Authorization and Accounting. (often called an AAA framework)

These terms do not really share a commonality until you start implementing a system that requires them.
