Security Metric for Object Oriented Class Design- Result Analysis

It is difficult to detect vulnerabilities in the operational stage of software, because the security concern are not addressed or known sufficiently early during software development. Accessibility (data encapsulation) and interaction (cohesion) related software metrics can be measured during the earlier phases of software development. The most importance of software measurement has led to the development of new software measure. To satisfy security requirement, it is important to protect data from unauthorized disclosure of information and alteration of information. Taking security early phase of a system development should have an impact on reducing many software vulnerabilities. A new methodology has been proposed in this paper to check accessibility and interaction of class design. These metrics allow designer of system to discover and fix the security of various alternative of class designs. We also mention the analysis of these metrics. These observations show that security design metrics can be used as early indicators of vulnerability in software.
