What are the benefits of limiting access to information?
What will be an ideal response?
Limiting access to information reduces the threat against it. Only those who must use data should have access to it. In addition, the amount of access granted to someone should be limited to what that person needs to know. For example, access to the management features of access points should be limited to approved technicians and security personnel. An office worker may be using the wireless LAN provided by the access point, but he should not be able to view or configure the AP settings because he has no job-related need to do so.
