Report Part A (80%): Security in Mobile Systems, Virtualization and Clouds
Our organisation, after implementing mobile services has discovered that a lot of the expected benefits have
not been achieved. While the staff agree and can see how the new untethered access to business data and
services can help in their day to day activities the overhead of using the services due to authentication has
made the system poorly accepted.
The security mechanism was imposed to limit the likelihood of having long term connections from external
partners which may be abused by external entities. The organisation has a large number of external business
partners who regularly connect to the organisation resources as part of cooperative business processes.
After the appointment of an external consultant specialising in dealing with user productivity and business
network design a number of problems were highlighted.
Firstly, the system was designed so that the security management was pushed onto the mobile devices making
the use of the service disruptive to the users. The accessing of different services while using mobile devices
required a separate login in to each service. Not only that, but prolonged inactivity would shut down the
connection to the mobile device requiring a twostep process to re-establish a connection to the device then
reconnection to the service.
Secondly, to implement the new network design making the data more accessible from various parts of the
network resulted in explosion in the number of duplicated physical servers on the system. Most of the time the
servers are idle in anticipation of work being allocated to them from a user connection. The extra servers
resulted as an expense in purchasing setting up and maintaining the servers for day to day operations. The
number of IT staff has doubled since the introduction of the new design just to be able to maintain all the
services and keep the systems functioning.
The consultation report suggested that more cost effective alternatives may be to either virtualize the servers
or move the services to an appropriate cloud. Once the design has been decided we could solve the multiple
log on requirements with the adoption of a single sign on solution.
These approaches and technologies are new to the organisation. The IT department grew up on the need to
provide services as they are needed and not a long term strategic planning for future needs. As a result you
have been tasked with writing a report to explain and explore the following technology and services:
a) Investigate and report on types of virtualizations and benefits to their adoption in an organisation? How will
the technological adoption help resolve some of the issues with the current network solution?
b) The world is currently abuzz with cloud services. Investigate and report what cloud services are, what kind
of cloud services is there and what is the benefit of the different type of services?
c) The report lists the adoption of a single sign on process as a part of the solution. Investigate and report
what are single sign on solutions and how do single sign on services work?
d) One of the reasons for original security design was the external connections with our partners. It was
recommended that they should consider a VPN solution for external connections. Investigate and report the on
types of VPNs, working and functionality of VPN and how they would help with the security requirements for
external partner access.
e) Seeing that we have two options as a possible solution to our current design (virtualization and cloud
services) which solution would you recommend that they adopt? Justify your recommendations.
Please read the next section very carefully.
Format for Assignment 3
Your report MUST follow the structure for a report as specified in the Faculty of Business Communications skills
handbook, however, you will not be required to submit the following sections: Glossary, or Appendices. You
may want to consider the structure of the marking scheme when structuring the body of your report.
Your report must include references(Harvard style) where you have used other sources (both in the
body text and listed at the end of the report) as specified in the Communication skills handbook.
Your report must be printed with 1.5 line spacing; at least 12-point font size; and the body of the
report should be no more than 20 pages of single-sided A4 paper. Penalty will apply for exceeding
the page limit.
Assignments not following the report style will be heavily penalised.
WIKIPEDIA is not considered a suitable reference source and its use in referencing is strongly
discouraged. You should not have it as a reference in the assignment.
. Failing to correctly reference your sources will result in submitted work being penalized severely.
