(b) Explain why the server should also have software security installed. [2]

(c) Identify two additional security measures that should be applied to PC 1 and PC 2. [2]

Answer

Answer Details

(a) The role of the hardware firewall in this network:

The hardware firewall filters all incoming and outgoing traffic between the internet and the internal network. [1]
It blocks unauthorised access attempts and potentially harmful data packets before they reach the server or PCs, acting as a barrier between the external internet and the internal network. [1]

(b) Why the server should also have software security installed:

The hardware firewall may not detect all threats, such as malware hidden in encrypted traffic or threats originating from within the internal network itself. [1]
Software security such as anti-virus software and a software firewall on the server provides a second layer of protection specifically for the stored data on that machine. [1]

(c) Two additional security measures for PC 1 and PC 2:

Install anti-virus software on each PC to detect and remove malware that may have bypassed the firewall. [1]
Require user authentication with strong passwords before allowing access to the network, ensuring only authorised users can log in. [1]
