Object Oriented Security - For the last 20 years, the number of vulnerabilities has increased near 20 times, according to NIST statistics. Vulnerabilities expose companies to risks that may seriously threaten their operations. Therefore, for a long time, it has been suggested to apply security engineering – the process of accumulating multiple techniques and practices to ensure a sufficient level of security and to prevent vulnerabilities in the early stages of software development, including establishing security requirements and proper security testing. The informal nature of security requirements makes it uneasy to maintain system security, eliminate redundancy and trace requirements down to verification artifacts such as test cases. To deal with this problem, Seamless Object-Oriented Requirements (SOORs) promote incorporating formal requirements representations and verification means together into requirements classes.
