Abstract
Small and Medium Sized Enterprises struggle to find strategies to achieve a high level of information security or are unaware of the risks posed by information technology. A lack of finance and IT departments that miss an information security officer increase the risk of exploited vulnerabilities. The alignment of Business Process Management and Security engineering manifested in the Security Requirements Elicitation using Business Processes approach provides a solution of this sector wide issue by introducing Security Risk-oriented Patterns applicable also for Business analysts. Patterns that are based on contextual areas illustrate business assets, vulnerabilities and risk treatment in form of security requirements. This is achieved by using the Business Process Model and Notation 2.0 modeling language and specifically engineered extensions which add the IT security domain. Outcome of this bridging is an applicable solution to elicit security requirements. Core of this thesis is the pattern application to measure their performance in a German SME. After business assets and security objectives were set, several pattern occurrences have been identified that resulted in a number of security requirements. Implementation abilities and usefulness with regards to the company underlined strong pattern performance. Moreover, a new pattern has been developed by using the Information System Security Risk Management Domain Model. Finally, the inclusion of prioritization and inspection techniques from the Security Quality Requirements Engineering methodology is suggested and extensions from the theorem of organizational configurations that enable further automation of SREBP. These modifications result in an approach that increases the security of Small and Medium Sized Enterprises.
