Security Factors in Effort Estimation of Software Projects

This contribution deals with problems related to an effort estimation of the software projects which are connected to the development of secured products. The aim of this contribution is to present an option of an effective consideration of the effort which is connected with the software products development. The FPA and COCOMO II methods for cost estimation are extended by the security factors, which are considered depending on requested security level of the resulting software product. The FPA method extended by security factors is called FPA&SF (Function Analysis & Security Factors) and the extended COCOMO II method is named as COCOMO II&SF (COCOMO II & Security Factors). An example of determination of the effort estimation by new methods FPA&SF and COCOMO II&SF is part of this contribution. These methods are used on an actual project and the acquired results are compared with values which were evaluated after a successful completion of the relevant project.
