State the main use of each of the access technologies below. In your answer, give
one example to explain how each access technology can be used to secure a
student record system in a tertiary college.
Access technologies:
B. Network Access Control (NAC).
The main use of Network Access Control (NAC) is to enforce security policies and control access to networks. It verifies the compliance of devices and users before granting them access to network resources.
Example: In a student record system in a tertiary college, NAC can be used to secure the network by ensuring that only authorized devices and users can connect to the system. For example, NAC can check if a device has the necessary antivirus software and latest patches installed before allowing it to access the student record system. This helps in preventing malware or unauthorized devices from compromising the system and ensures that only trusted devices can access sensitive student data.
