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. Report Part B (20%): Presentation of the Report Security in Mobile Systems, Virtualization and Clouds You are to prepare and present major findings in the report. You are to treat this as a management presentation of the report’s findings. The report presentation should not be longer than 12 minutes so you will need to really think hard about what to include in your talk. Again the presentation is preferred to be Power Point Slides with voice over or any other compellable technologies that will allow you to record the slide show and your voice.

Vitalizing is an application which separates the operating system from the application. The application then runs on the server or on another remote computer rather than on the computer where it is being used. One major benefit of application virtualization is that you can run incompatible applications at the same time. We can also run the application that is not designed for the operating system of the computer from which you are accessing it.

Virtualization

Virtualization is mainly about how effectively we plan to utilize the resources or components. Bigger components like server or any other component can be divided or split into smaller ones .It allows many number of different instances of technology can be made to run parallel without much interference.

Different types of virtualization are:-

  1. Storage virtualization
  2. data virtualization
  3. server virtualization
  4.  application virtualization
  5.  network virtualization
  6.  operating system virtualization
