    Security and Ethical Policies in Information Technology: An Analytical Report 1. (TCO A) You are responsible for developing a security evaluation process that can be used to assess various operating systems both during and after development. List the five most desirable qualities your evaluation process should have and explain why they are important. (Be sure to address qualities of the evaluation process, not specific metrics for assessment of operating systems.) (Points : 40) The evaluation process can be approached and attempted with our own set of parameters. The desirable qualities that would be important for the evaluation process have been described below - Speed – This is to ensure that in the product is ready for the competitive market soonest possible, given that time is money and companies need to get their products out in the market as soon as possible Thoroughness – This is required to guarantee that all the various features and aspects of the product have been evaluated Portability – This quality ensures that the product is platform independent and that the evaluation is applicable without any platform related constraints or dependencies, thus allowing the evaluation process to be used for a range of systems and products Consistency – This criterion is to ensure that all similar products are judged and evaluated based on the same set of parameters, and that the same product when judged by different panels receive the same results Granularity – This is to ensure that the evaluation of the product is based on adequate level of detailing, which ensures that all parts of the system are evaluated effectively 2. (TCO B) The Open Systems Interconnection model is inherently inefficient. On the source host, each layer must take the work of higher layers, add some result, and pass the work to lower layers. On the destination host, each layer must process these results from lower layers and pass the appropriate information to upper layers. Surely this wrapping and unwrapping process is inefficient. Assess the security advantage of this layered approach. (Points : 40) As per the Open Systems Interconnection, or the OSI model, there are seven layers through which a message needs to pass from a source to a destination machine. Each of the layers perform different functionalities, and are together responsible for the complete and secure transmission of the message. Each layer performs some sort of function on the message before passing it to the next layer. This mechanism ensures high level of security. For example, at the source system, the seventh layer, or the
