Consider an area of information technology (IT) security, such as, network security, e-mail security, database security and so on. Identify and research three different commercial IT security solutions/products for the chosen security area. The three products must target the same security issues. [Note: Instead of IT security-specific products such as antivirus software etc. you may also choose to research the security features of products such as database management systems, operating systems and so on.] Prepare a report providing categorical feature comparison for the three products in the chosen category and make recommendations about the products to assist purchasing decision. Your report may include the following sections: Executive overview. Introduction. Product description. Detailed feature comparison. Conclusions and recommendations. Reference list Appendices (if any) Length of the report:1500~2000 words, excluding references and appendices. Rationale This assessment item is aligned with the following learning outcome of the subject: be able to justify security goals and the importance of maintaining the secure computing environment against digital threats; Depending on the IT security area chosen, the assessment item also relates to one or more of the following learning outcomes of the subject: be able to explain the fundamental concepts of cryptographic algorithms; be able to examine malicious activities that may affect the security of a computer program and justify the choice of various controls to mitigate threats; be able to compare and contrast the security mechanisms of a trusted operating system with those used in a general-purpose operating system; be able to investigate and justify the use of the access control mechanisms and user authentication processes; be able to compare and contrast foundational security policies and models that deal with integrity and confidentiality.
