In a networked global economy, cyber security threats have accelerated at an enormous rate. The security infrastructure at organisational and national levels are often ineffective against these threats. As a result, academics have focused their research on information security risks and technical perspectives to enhance human-related security measures. To further extend this trend of research, this study examines the effects of three knowledge sharing methods on user security practices:

... training, social media communication, and local security experts (non-IT staff). The study adopts a phenomenological method employing in-depth focus group interviews with 30 participants from eight organisations located in Ho Chi Minh city, Vietnam. The study expands on understanding factors contributing to self-efficacy and security practice through various knowledge sharing channels. Current methods of periodical training and broadcast emails were found to be less effective in encouraging participants to develop security self-efficacy and were often ignored. Security knowledge sharing through social media and local experts were identified as supplementary methods in maintaining employees' security awareness. In particular, social media is suggested as a preferred channel for disseminating urgent security alerts and seeking peer advice. Local security experts are praised for providing timely and contextualised security advice where member trust is needed. This study suggests that provisions of contemporary channels for security information and knowledge sharing between organisations and employees can gain regular attention from employees, hence leading to more effective security practices.
