Plan, Develop and Manage a Security Policy

TASK

Assignment Two is comprised of two parts and your report should be no more than 5 pages excluding the cover page, table of contents and references.

Part One 

Plan, Develop and Manage a Security Policy (10 marks)

Background: 

Consider that the Commonwealth Government of Australia is planning to launch ‘My Health Record’ a secure online summary of an individual’s health information. The system is available to all Australians, My Health Record is an electronic summary of an individual’s key health information, drawn from their existing records and is designed to be integrated into existing local clinical systems. 

The ‘My Health Record’ is driven by the need for the Health Industry to continue a process of reform to drive efficiencies into the health care system, improve the quality of patient care, whilst reducing several issues that were apparent from the lack of important information that is shared about patients e.g. reducing the rate of hospital admissions due to issues with prescribed medications. This reform is critical to address the escalating costs of healthcare that become unsustainable in the medium to long term. 

Individuals will control what goes into their My Health Record, and who is allowed to access it. An individual’s My Health Record allows them and their doctors, hospitals and other healthcare providers to view and share the individual’s health information to provide the best possible care. 

The 'My Health Record' is used by various staff such as System Administrator, Doctor, Nurse, Pathologist and Patient. In order to convey and demonstrate the rules and regulations to the users of this system, Commonwealth Government of Australia needs a security policy.

You are employed as the Security Advisor for the organization. The task that is handed to you by the Chief Information Officer now is to create, develop and manage "System Access Security Policy” for atleast any 3 users of the system. 

Complete the following in your security policy:

·         Plan System Access Security Policy

·         Develop System Access Security Policy  

·         Manage System Access Security Policy  

 

 

Part Two 

Conducting a Risk Assessment (10 marks)

You will be given a list of organisation in week 3 by your lecturer and you can select any one organisation from them. The organisation uses various IT systems for its daily operations. Assume that you are appointed as an IT Systems Auditor for the chosen organisation and you are asked to provide a risk register must come up for the IT systems in the organisation. 

·         A brief introduction of the organisation and the IT systems

·         Identify and explain any major risk in the IT systems components 

·         Discuss the consequences of the risk 

·         Inherent risk assessment, that is the assessed, raw/ untreated risk inherent in a process or activity without doing anything to reduce the likelihood or consequence

·         Mitigate the risk 

·         Residual risk assessment, that is the assessed, risk in a process or activity in terms of likelihood and consequence after controls are applied to mitigate the risk.

·         Create a Risk Register based on the risks identified in the IT systems and prioritise of the risk using a standardised framework such as the ANSI B11.0.TR3 Risk Assessment Matrix

Given the fact there is no clear prioritisation framework NOR risk appetite framework, the risk register is your professional assessment of the likelihood and consequence of the risks you identify. When preparing your risk register you should think carefully about the assets the chosen organisation may have and how these may be compromised from the perspective of Information Security.

Rationale

This assessment task will assess the following learning outcome/s:

  • be able to justify the goals and various key terms used in risk management and assess IT risk in business terms.
  • be able to apply both quantitative and qualitative risk management approaches and to compare and contrast the advantages of each approach.
  • be able to critically analyse the various approaches for mitigating security risk, including when to use insurance to transfer IT risk.
  • be able to critically evaluate IT security risks in terms of vulnerabilities targeted by hackers and the benefits of using intrusion detection systems, firewalls and vulnerability scanners to reduce risk.

 

Answer Preview

Before developing the security policy, it is crucial to have a strategic plan which will help in setting the security goals of the system based on its objectives. The strategic planning for the security policy includes elements such as:

1.      The authority controls of the system.

2.      Monitoring, measurement, and reporting of activities relating to how the policy is used.

3.      The awareness and education program used to the people affected by the policy.

4.      Access controls used for the system.

5.      Privacy program in the system.
