Proposed Secure Activity Diagram for Software Development

Unified Modeling Language (UML) activity diagrams are derived from use case diagrams. It becomes essential to incorporate security features and maintain consistency in the during analysis phase of Software Development Life Cycle (SDLC). As part current software development practices, must be a constant effort. The used model business process. detailed diagram is done. challenge lies viewing main attacker's perspective providing defense mechanism mitigate attacks. This paper presents an extension named SecUML3Activity provide with Object Constraint (OCL) constraints using Five Primary Security Input Validation Attributes (FPSIVA) parameters for input validation. also proposed three color code notations stereotypes White represent normal state. Red dotted line attack components. Blue double defensive algorithm against SQL Injection (SQLI) attack, Cross Site Scripting (XSS) DoS/ DDoS access validation provided. mapping Secure 3-Use Case done through mathematical modeling.
