Question requires you to develop firewall rules based on a fictitious organisation.
Scenario:
You work for a security-conscious company, xC-Cure, who develop encryption technologies for large corporate and defence customers world-wide. Your role is a junior security specialist and you have recently been asked to plan for the deployment of a new firewall.
