  Knowledge leakage poses a critical risk to the competitive advantage of
knowledge-intensive organisations. Although knowledge leakage is a
human-centric security issue, little is known about leakage resulting from
individual behaviour and the protective strategies and controls that could be
effective in mitigating leakage risk. Therefore, this research explores the
perspectives of security practitioners on the key factors that influence
knowledge leakage risk in the context of knowledge-intensive organisations. We
conduct two focus groups to explore these perspectives. The research highlights
three types of behavioural controls that mitigate the risk of knowledge
leakage: human resource management practices, knowledge security training and
awareness practices, and compartmentalisation practices.
