, QUESTION 1
1.1 Briefly discuss Critical Infrastructure. Include in the following in your discussion: (6)
• A definition of the term “Critical Infrastructure”,
• Two examples of Critical Infrastructure, and
• An explanation of how each of your listed examples can be classified as Critical Infrastructure.
Answer:
Definition
Critical Infrastructure: (2 marks) – There are many ways of defining the term.
• A critical infrastructure is something that people depend on, either directly or indirectly, for their lives and wellbeing,
in any time frame.
• The term Critical Infrastructure (CI) is used to refer to infrastructure that is crucial to the effective and efficient
functioning of a country.
Two examples of Critical Infrastructure (2 marks), and two valid explanations of their criticality (2 marks)
1.2 Briefly discuss Critical Infrastructure Protection. (4)
Answer: (Any 4 facts, 4 marks each) – Question requires students to identify important facts to include in their
discussion on their own.
• Critical Infrastructure Protection
• The research field where all efforts exerted in the creation of security enhancing methods and policies for
critical infrastructure are studied and implemented.
• Security efforts in Critical Infrastructure require large investments from the responsible entity
• These investments are often geared towards:
• Upgrading structural facilities of the infrastructure;
• Hiring human resources to protect the infrastructure;
• Performing audits on the facilities;
• Developing software components to detect and prevent attacks against the infrastructure.
• Three types of effects that could indicate the vulnerability of a Critical Infrastructure system. These are:
• Direct infrastructure effects;
• Indirect infrastructure effects;
• Exploitation of infrastructure.
• Due to Critical Infrastructure interdependencies and the high chance of occurrence for cascading and escalating
failures; nations have begun to stipulate national strategies to mitigate against the risks of failures in the Critical
Infrastructure networks.
