Assignment 2: Defensive Audit (1500 words)

Assignment 2: Defensive Audit (1500 words 30%)
Despite the strictest security protocols and measures, every organisation has certain vulnerabilities that can be exploited by hacking attacks. Once these vulnerabilities are identified, cyber security professionals need to be well-equipped to securing them. Occasionally, however, these may not be secured in time. A security consultant also needs to be able to counter the attack with the resources available.
This Assignment 2 requires you think about the multiple ways in which a business or an organisation’s security vulnerabilities can be exploited and you will be required to defend against such attempts so as to disrupt a hacking attack and securing the organisation’s vulnerabilities. 2nd Assignment: Defensive Auditing (1500 words 30 percent )
Although every organization has specific vulnerabilities that can be exploited by hackers, even those with the tightest security policies and precautions are susceptible to assault. As soon as these vulnerabilities are found, cyber security experts must be well-prepared to take steps to mitigate their impact. On rare occasions, however, these may not be secured in time for the event. In addition, a security consultant must be able to counter an assault with the resources at his or her disposal.
You will be required to consider the various ways in which a business or organization’s security vulnerabilities can be exploited, and you will be expected to defend against such attempts in order to disrupt a hacking attack while also securing the organization’s vulnerabilities in this Assignment 2.
Instructions
In this assignment, you will be provided with three context briefs from which you will be required to select any one business or organisation for your analysis and complete the tasks below (A & B). As much as possible, focus on the details provided in the brief. Where information is not provided but integral to your analysis, make reasonable assumptions (which should be clearly stated and explained).
1. Vulnerability Analysis (25%)
2. Security Plan (75%)
1. Vulnerability Analysis
You will be required to assess organisational vulnerabilities for your chosen context, and develop a defence plan to disrupt the hacker’s activities.
Select three organisation vulnerabilities and compare them in terms of:
1. Level of potential exposure
2. Likelihood of this vulnerability being exploited
3. Magnitude of potential impacts
Please note that your three selected vulnerabilities should vary in all the above mentioned characteristics.
2. Security Plan
Based on your chosen vulnerabilities, propose a security plan that can be implemented by your organisation to reduce exposure. Your security plan should include:
1. Focus on the social and organisation elements of ensuring good security, and the trade-offs between security and freedom.
2. Suggest 3 approaches this organisation could take to enhance their cybersecurity, and for each approach discuss
o The resources required to implement this framework
o Assessment of the effectiveness vs. costs of your proposed security plan
o Ability of the proposed framework to cover multiple vulnerabilities
o Implications on the organisation and their core business
o Trade-offs between security, privacy and freedom
3. How does the global environment around hacking improve or complicate your defense plan? Discuss the role of the local and global hacking community. Provide an example of one global organisation that could help you.
