Collaborative security risk estimation in agile software development
PurposeToday, agile software development teams in general do not adopt security risk-assessment practices in an ongoing manner to prioritize security work. Protection Poker is a collaborative and lightweight software security risk-estimation technique that is particularly suited for agile teams. Motivated by a desire to understand why security risk assessments have not yet gained widespread adoption in agile development, this study aims to assess to what extent the Protection Poker game would be accepted by agile teams and how it can be successfully integrated into the agile practices.Design/methodology/approachProtection Poker was studied in capstone projects, in teams doing a graduate software security course and in sessions with industry representatives. Data were collected via questionnaires, observations and group interviews.FindingsResults show that Protection Poker has the potential to be adopted by agile teams. Key benefits include good discussions on security and the development project, along with increased knowledge and awareness. Challenges include ensuring efficient use of time and gaining impact on the end product.Research limitations/implicationsUsing students allowed easy access to subjects and an ability to collect rich data over time, but at the cost of generalizability to professional settings. Results from interactions with professionals supplement the data from students, showing similarities and differences in their opinions on Protection Poker.Originality/valueThe paper proposes ways to tackle the main obstacles to the adoption of the Protection Poker technique, as identified in this study.
