Decision Support System for Selection and Ranking Security Alternatives

Nowadays, there is wide range of alternatives for hardware and software available in the market, this would create a complex problem for agencies decision makers to select the best tools, software and hardware. When it comes to the information security, alternatives selection is become one of the most important issues. During the network security design, a number of hardware, software, need to be selected in order to make the required design. This design would increase the security and the acceptance of the decision makers. Selection of software and hardware are classified as a daily multi-attribute problem with conflicting criteria. Performance, reliability, usability and other features would play important roles in the selection process. In this paper, we proposed a framework for security tools selection using hybrid of TOPSIS and AHP, AHP is used to calculate the criteria weight while TOPSIS is used with the calculated weight to rank the available security hardware and/or software alternatives. According to the ranking result, the decision maker can select the best alternative with respect to his/her preference.
