As modern organizations rely more on their information systems, mitigating information security risks becomes essential. Weaknesses in the information security management chain have continued to be challenged by employees. Therefore, enhancing employee security awareness becomes critical. Considering the effectiveness of informal methods, this research examines security advice sharing as one of the operative ways. Accordingly, in this paper, by adapting the theory of planned behavior as our theoretical lens, we propose a conceptual model of factors that are anticipated to impact the willingness of employees to share security advice. Finally, conclusion and avenues for future research are discussed.
