A
Correct answer
Explanation
Firewalls are network security devices that monitor and control incoming and outgoing network traffic based on predetermined security rules. They primarily protect against unauthorized access attempts and attacks from external networks.
-
Constant authentication of device and user
-
Compulsory pairing and bonding between two devices
-
Device authentication
-
All of the above
C
Correct answer
Explanation
Bluetooth security includes device authentication, which verifies the identity of connecting devices. While pairing and bonding are also part of Bluetooth security, device authentication is a core security provision that ensures only authorized devices can connect. The question correctly identifies this as a distinct security feature.

Collaborative computing
A
Correct answer
Explanation
This security mechanism is used to protect against known or unknown vulnerabilities in the OS and software.
-
Encryption
-
Static Keys
-
Network Interface Card (NIC)
-
None of these
B
Correct answer
Explanation
Email uses encryption for security, dynamic (not static) keys for authentication, and requires Network Interface Cards for connectivity. Static keys are not a standard characteristic of email systems, as encryption typically uses dynamic or session-based keys.
-
access control for on line data
-
authorisation and authentication of users
-
reporting of before and after images
-
none of these
C
Correct answer
Explanation
Processing control procedures maintain data integrity by recording before and after images of transactions. This creates an audit trail that allows recovery in case of system failure or error detection. Access control and user authorization are security measures, not processing controls.
