Determining access controls
“Authorization functions” is a process by which access to a
particular IT asset can be granted or denied, while access control is
used to enforce the rules for authorization. There are several access
control models, including “role-based” AC, “discretionary” AC,
“mandatory” AC, and “attribute-based” AC. Imagine that, as the security
administrator for a medium-sized retail-based organization with around
2000 users, you are tasked with determining the appropriate level of
access for a new user in the Human Resources department. What approach
would you take to determine access for this person? What methods would
you use to verify that the choice of access controls is appropriate for
this user?
