Computer Security and Protecting Systems Assignment

Assignment Task

Scenario

You have been hired as an apprentice IT Operations Technician at a small engineering firm specialising in computer aided manufacturing.  The Managing Director of the company has tasked you with researching and upgrading the security of the computer system used for the storage of designs and specifications to bring it in line with the security used in their customer management web portal.

Task

Prepare a plan for the improvement of security to protect the engineering computer system from threats.   

Carry out the following analysis procedures on the current computer system:

• Use tools and methods to assess the vulnerabilities, including port scanners,  eq NMAP
• Web vulnerability scanners
• General vulnerability detection software
•  Audit of systems and network designs
• Penetration testing for common threats in OWASP top 10

Perform risk assessments on the system for each possible threat, including giving a measure of its severity using an appropriate method of calculation.  Justify how you reached your measure of severity for each risk, and suggest how they can be reduced.  Identify the most severe risks and highlight them as a focus for your implementations.

Updated security policies should form part of your plan, including analysis on methods of breaching the system and appropriate responses.

Develop a test plan that can be used to check that your implementations were a success.

Implement the security measures laid out in your plan.  You should ensure all implementations are fully documented providing evidence of the before and after effects of the measure.  Complete your test plan with results from performing the procedures carried out during the planning stage to ensure the improved security measures are a benefit to the system, suggesting further improvements to the system where appropriate.  Evaluate how the improvements to the system are beneficial and have no major impact on the user.
