A Tagging Approach to Extract Security Requirements in Non-Traditional Software Development Processes

While software security has become an expectation, stakeholders often have difficulty expressing such expectations. Elaborate (and expensive) frameworks to identify, analyze, validate and incorporate security requirements for large software systems (and organizations) have been proposed, however, small organizations working within short development lifecycles and minimal resources cannot justify such frameworks and often need a light and practical approach to security requirements engineering that can be easily integrated into their existing development processes. This work presents an approach for eliciting, analyzing, prioritizing and developing security requirements which can be integrated into existing software development lifecycles for small organizations. The approach is based on identifying candidate security goals using part of speech (POS) tagging, categorizing security goals based on canonical security definitions, and understanding the stakeholder goals to develop preliminary security requirements and to prioritize them. It uses a case study to validate the feasibility and effectiveness of the proposed approach. A Tagging Approach to Extract Security Requirements in Non-Traditional Software Development Processes
