Task 1
Task 1.1
For this assignment, the selected Australian organization is Commonwealth Bank of
Australia or CBA. It is one of the listed organizations in the ASX or Australian Stock
Exchange that is eventually operating in the banking sector (Commbank.com.au.
2018). It is one of the most popular and significant multinational banks that has its
businesses in Asia, New Zealand, Australia, United Kingdom and United States. This
popular banking sector is responsible for providing various financial services. These
services mainly include business banking, retail service banking, superannuation,
investments, funds management, broking services and many more. Commonwealth
Bank of Australia is registered as one of the “Big Four” banks in Australia and New
Zealand. This bank started its journey in the year of 2011 by the Government of
Australia and became completely privatised in the year of 1996. The headquarters of
this organization is in Darling Harbour, Sydney, Australia. There are more than 1100
branches in the entire world and the net revenue in a year is about 26.005 billion
Australian dollars. The net income of this organization is approximately 9.881 billion
Australian dollars (Commbank.com.au. 2018). The total number of employees in the
Commonwealth bank of Australia is 52000. The role of this bank in the central
banking exponentially expanded after 1920. The most valuable factor that is being
offered by this particular organization is the easiest loan providing services. Due to
the excellent organizational strategies, The Commonwealth Bank has become
extremely important as well as significant for the citizens of Australia and New
Zealand. The major objective of this bank is to provide excellent services for their
customers and retain the customer relationship management successfully
(Commbank.com.au. 2018). The main reason for selecting this organization of CBA
is that they are properly engaged with the information services by means of making
subsequent utilization of various online platforms as well as various technological
aspects.

Task 1.2
This particular section of the report focuses on the significant analysis of
Commonwealth Bank of Australia in respect to the security and privacy policy

statements, which are available on their website (Tricker and Tricker 2015). The
privacy governance and the data security of this organization are properly addressed
with the nine core principles of Data Governance Australia Code of Practice. It is the
principles based self regulatory regime, which sets the standards or benchmarks of
any leading industry that are responsible for making the organization absolutely
ethical and legal (Datagovernanceaus.com.au. 2018). The core nine principles for
the data privacy and security of Commonwealth Bank of Australia are as follows:
i) No harm Rule: According this principle, the reporting organization is needed
to utilize the best endeavours to ensure the fact that collection, disclosure or use of
any personal information of the person does not intend in causing harm or threat to
the particular individual (Capaldi, Zu and Gupta 2013). Moreover, that organization
working with integrity like data usage is not at all regarded as unethical. Any
personal information must not be disclosed to the third party any type of data
collection must not be exploited. For the organization of Commonwealth Bank of
Australia, several important and significant steps are being undertaken to ensure that
they are following the obligations of privacy or confidentiality. Hence, their
organizational confidential information is secured and protected. Furthermore,
various security measures are being adopted by them and access is controlled for
maintaining the authenticity of the information (Kraakman and Hansmann 2017).
This is securing their information and thus their data is secured.
ii) Honesty and Transparency: The second principle is honesty and
transparency. As per this principle, the organization is required to work with honesty
and transparency when the data is being used, collected and disclosed (Davies
2016). The specific fact should be ensured by this organization is that any type of
data collected by them is done according to this rule and is transparent enough to be
overviewed by organizational employees and clients. The proper collection of
information by the Commonwealth Bank of Australia is eventually done as per the
updated practices. They are strictly adhered to the principle of honest and
transparency and thus is termed as the most important and rules abiding
organization (Cheffins 2013). The information related to their clients could be easily
accessed for periodical unanticipated utilization and which is not disclosed in any
privacy notice. Several security features are available for both the employees and
customers that help in securing their data or information properly. The significant

feature amongst these is providing a unique username and password for each of the
customers. Moreover, if any of the organizational body or customer loses their
username and password, there is an option to retrieve or recover that easily and
promptly. This feature even help to mitigate the issues related to security of
passwords (ArAs 2016). As per the Privacy Act 1988, Commonwealth Bank of
Australia is bound to provide the best customer experience and make them satisfied.
iii) Fairness: The third principle of DGA codes of practice is fairness. The
fairness to use collected as well as disclosed personal information is done by taking
into consideration of various factors like proper community expectations about
utilization of personal information and the chances of harm to the specific
organization (Obradovich and Gill 2013). This even determines the perfect time for
retrieving the personal data or information. This personal information is to be
collected by the particular organization for any specific business purpose. This type
of information cannot be retrieved if there is not proper purpose of business. The
significant right to access this personal information by the organization of
Commonwealth Bank of Australia is somewhat different from the privacy of law. This
organization is often being unfair to their customers and they are utilizing the
personal information of customers in other unfair means (Todorovic 2013). Hence, it
is needed for Commonwealth Bank of Australia to be completely fair to their
customers in maintaining the information.
iv) Choice: The next principle of DGA codes of practice is choice. As per this
rule, there should be a proper choice to use and collect any personal information.
For the organization of Commonwealth Bank of Australia, the specific principle for
personal information is not being properly followed by them and hence they should
eventually re identify their choice of external information (Bottomley 2016). This
would help in preserving the data properly and the individual’s consent would be
required.
v) Accuracy and Access: As per this principle, the accuracy of the data or
information should be maintained properly and it should be ensured that the data
that is being shared is not inaccurate. Perfect access to the confidential information
is next important requirement in this principle (Beekes, Brown and Zhang 2015). The
wrong access to the information should be checked and stopped and for this

purpose, the specific reporting entity must take up few steps. When the organization
of Commonwealth Bank of Australia is considered in this case, it is reported that they
provide proper, accurate and genuine data to their customers. For their data
accuracy, the organization is well accepted by every user worldwide. Furthermore,
they have been useful in restricting their personal data perfectly and hence there is
extremely less chance of data loss or data theft (Datagovernanceaus.com.au. 2018).
They have maintained their choice to use and collect personal information, which are
easily understood by everyone.
vi) Safety, Security and De Identification: According to this principle, the
organization of CBA must subsequently organize or design their security as per the
standards of a recognized industry. This would stop them in data security breaching
and all types of harms could be restricted. They should recruit a person, who would
be responsible for checking all types of data security and this would then stop the
chances of data breaching to a greater extent (Young and Thyil 2014). Moreover, the
data set could be collected and stored properly. Apart from this, they must ensure
that the procedure of de identification is remained robust with the help of regular
testing and up gradation of tools and techniques.
vii) Accountability: One of the most significant principles of DGA codes of
practice is accountability. This helps to maintain as well as create various personal
information categories and why this information should not be disclosed to any third
party. The proper method of collection, utilization and disclosure of personal
information is checked here (Commbank.com.au. 2018). The transactions that are
done within the reporting entity should be accurate and genuine. As the organization
of Commonwealth Bank of Australia is a banking sector, this particular principle is
the most important of all. The transactions of the organization should be proper and
there should no chance of fraud cases. The customer information should be
maintained with laws and a code of compliance must be ensured in the process.
viii) Stewardship: When the data privacy and security policy is being reviewed
for Commonwealth Bank of Australia, it could be inferred that nothing is mentioned
regarding stewardship principle. Hence, it is extremely important for them to
incorporate this particular principle within their business
(Datagovernanceaus.com.au. 2018). This would then require a specific officer, who

would be responsible for creating rules and compliance with the code. Moreover,
proper training is also required for the employees of Commonwealth Bank of
Australia to handle the data practices perfectly and without any such complexities.
ix) Enforcement: The final principle of DGA codes of practice is enforcement.
It is completely related to the compliance and the specific code is enforced by the
company periodically (ArAs 2016). In Commonwealth Bank of Australia, the codes
should be properly enforced for making it a member of data governance.

Task 2
Task 2.1
The conduction of EDA or exploratory data analysis for diabetes data, with the help
of rapid miner initially needs the proper understanding of data fitting procedure within
the software and also the procedure of building the process. EDA started with data
import within rapid miner and finally saving it in the local storage. As soon as the
data is being stored, the data set is then dragged within the section of process layout
and thus connecting it to output port. When the run button is being pressed, rapid
miner would return the basic statistics and data set in a summarized form as
provided below:
Figure 1: Summary Statistics Table
The analysis is eventually performed as the process of cleaning of provided set of
raw data. In this particular case, the data set is of diabetes. IT comprises of one
dependent variable and eight independent variables. Every variable is not vital for
the prediction of dependent variables (Lin et al. 2014). As per this analysis, the set of
5 to 6 variable are enough for predicting the one dependent variable.
Three step analysis is being performed by the analyst for identification of the top 5
variables, which are enough for predicting diabetes of any person. After several
research works, it is reported that blood pressure, BMI, age, amount of insulin in
