Part One – Plan, Develop and Manage a Security Policy
Introduction
This report is designing to explain “My Health Record” system’s planning information.
Australian’s Commonwealth Government is planning for launching a health record system for all
Australians. This system will keep information about the doctor, pathologist, nurse,
administrator, and patient’s health. Part one will describe the information about planning of
security policy, development of security policy, and management of security policy.
Plan Security Policy
Role of Security Policy’s planning: Security policy plan works as formal security plan that is
utilized to define an action plan for protecting and controlling information system or computer
system such as “My Health Record” system. Typically security policy’s plan includes:
 List of authorized users / persons that can be accessed the system.
 Access control method (how persons will use the system)
 Weakness and strengths of the system & how weaknesses will handle
 Also, include system restoration / backup procedures (Techopedia, 2019).
Best Strategic planning for security policy: The strategic planning for security policy is a very
important document for organization to maintain the security of information of users. The best
strategic planning of security policy is detailed process that contains initialization, planning,
implementation, monitoring and controlling of the user’s information. The best strategic
planning prioritizes and defines security initiatives and information assurance that organization
should enhance the information’s protection & related technology (Bada et al., 2019).
The requirement of Resources planning for security policy: Proper resource planning is also
playing important role to make security policy for IT system (health record system) because,
with the help of proper resource planning, organization can make best use of each employee’s
skills. It will also help to manage the entire user’s information at one place in the IT system. It
will also helpful to predict the different risk that can be affected the security policy of IT system
in the future. The proper resource planning also keeps all the information about security policy in
visual format. Hence, it is essential for security policy’s planning in IT system.
On the basis of learned information, the two-way authentication process can be implemented in
the security policy of IT system that will be helpful for Australian’s Commonwealth Government
to save the information of users and they can enhance the security level of health record system.

Develop a Security Policy
Intent & Rationale of Security Policy: The main purpose of security policy is to ensure or
confirm the security’s integrity of the IT system so that maintain the security level of the IT
system. The second purpose of security policy is to plan proper guidelines for the users so that
the health information of the users can be saved or secured from the unauthorized users. The
security policy also intends to identify IT security risks in a prior manner so that they can be
eliminated at right time and secure the health information of all users in the health record system.
Definition: The security policy will work as a written document for Australian’s Commonwealth
Government to protect and handle the health information of users from security threats and
authenticated users. It also provides proper guidelines to handle the security threats if these types
of threats will occur in the health record system of Australian’s Commonwealth Government.
Responsibilities of Individuals: In this health record system, the main three members will be
responsible to develop the security policy for this IT system such as:
 The first member will be responsible to implement and set the user access control & access
management system in IT health record system.
 The second member will be responsible to monitor application and network security
performance by identifying irregular activities.
 The third member will be responsible to control and update the security policy of a new
health record system from time to time according to the situation (Varadharajan et al., 2018).
Scope of Policy: The scope of security policy is concerned with the security and management of
the IT system’s information assets. The information assets can be health information of users,
information processing system, and information storage system in health record system. Main
scope of security policy is to maintain security in the health record system (Cho & Ip, 2018).
On the basis of learned information, it can be said that Australian’s Commonwealth Government
can use endpoint prevention and detection tools to maintain the malicious hacks in the IT system.
Manage Security Policy
Monitoring of Security Policy: Australian’s Commonwealth Government will utilize the
intrusion detection and prevention technology to monitor the security policy of the health record
system, the. The organization is also using network layer anti-malware and advanced threat
protection technique to protect health data from any security issue. They are also using data loss
prevention technique to monitor the unauthorized access of health data of user
4

Controlling of Security Policy: By blocking the unauthorized users, the organization control
security policy of the IT system. For that purpose, they utilize the two-way authentication login
to limit these types of users. They also utilize firewalls, logical access control and antivirus
software to control the malware and unwanted material to the maintain security of IT system.
Outcome of Security Policy: The security policy has offered the physical and technical control
for protecting integrity, availability, and confidentiality of health information of users in the
health record system. These policies have also reduced the occurrence of malware and security
threats by identifying different types of security risks in the IT system (Ketel, 2018).
Update Security Policy in Regular Intervals: Organization conducts a top to bottom security
policy audits to keep track of policies and identify security issue. After that, organization
implements new security policy by implementing new antivirus and malware prevention method.
The organization also implements new rules and regulations of data security to enhance security
policy on the regular intervals in the IT health record system (Infosec Resources, 2018).
Conclusion
From part one, it has concluded that Australian’s Commonwealth Government has planned and
developed the security policy to manage the security of health data of users in the health record
system. They have also utilized different techniques to monitor and control the security policies
so that they can enhance the security policy at regular intervals.
Part Two - Conducting a Risk Assessment
Introduction
Commonwealth Bank of Australia is one of the Australian multinational banks which are
working in the US, UK, Asia, and New Zealand. It delivers the different types of financial
serveries such as fund management, broking & investment services, superannuation insurance,
etc. The Commonwealth Bank utilizes IT system to provide banking services facilities at the
instant time. For providing online banking services, Commonwealth Bank utilizes NetBank IT
system that allows bank’s customers for transferring funds, managing account information, etc.
Risk Assessment
The bank utilizes risk assessment for identifying those situations, things, processes, etc. that can
be harmed bank and user’s information. After identification of risks, bank eliminates those risks
by using proper mitigation techniques in the IT system (Modarres, 2018).

Justification to Conduct Risk Assessment
Conducting the risk assessment has allowed the bank for minimizing the risks in the IT system and comply the safety regulation &
help in the IT system. Hence, risk assessment is managing the proper maintenance and security at the server so that it will not affect
the information of bank and users in the future. Conducting the risk assessment has also provided the proper awareness to the bank
about the technical hazards and failures that must be resolved on the time so that the IT system can work properly (Kroner, 2019).
Conclusion
From the second part, it can be concluded that the Commonwealth Bank of Australia has utilized the net banking IT system for
transferring funds, managing account information, etc. facilities to the customers. Bank has identified the different technical risks by
using risk assessment and bank has also implemented the different mitigation technique to eliminate these risks.
