Table 3: Common themes and patterns of the literature. encryption, and the provision of organizational, managerial, and technical controls. Theme 3 covers two aspects: maintaining user trust and addressing privacy concerns. Theme 4 also covers two aspects: the impact of human behavior on neural networks and the need for a system of cultural transmission and civic education. Theme 1: Security threats and vulnerabilities. One of the major challenges in addressing security threats and vulnerabilities in chatbots is the constantly evolving nature of cyber threats. New attack vectors and vulnerabilities are being discovered all the time, and developers need to stay up to date with the latest security measures to ensure ongoing protection of their chatbots. For example, the recent rise in phishing attacks using chatbots highlights the importance of implementing measures to prevent malicious input and contextual attacks. Another challenge is the need to balance security with usability. Chatbots need to provide a user-friendly experience while also ensuring the confidentiality, integrity, and availability of user data. Developers must carefully consider the trade-offs between security measures and user experience and find a balance that meets both requirements. For instance, chatbots in the healthcare industry must comply with strict regulations regarding data privacy and security while also providing timely and accurate medical advice. Theme 2: Solutions to mitigate security concerns  
The lack of standardized security measures for chatbots poses a significant challenge in addressing security concerns. Developers need to determine which security measures to implement, how to implement them, and how to ensure their effectiveness. For example, while end-to-end encryption is a promising solution to protect user data, its implementation may be difficult for small- or medium-sized chatbot providers due to cost constraints. Figure 4: Taxonomy of information security in chatbot. Another challenge is the need for effective organizational, managerial, and technical controls. Chatbots are often developed and deployed by teams with varying levels of expertise and experience in information security. Developers must ensure that all team members are properly trained in information security and follow best practices to prevent security breaches. Additionally, developers must ensure that their chatbots have appropriate technical controls, such as access control mechanisms and monitoring tools, to detect and respond to security threats in a timely manner. Theme 3: User trust and privacy concerns  
One of the challenges in addressing user trust and privacy concerns is the lack of transparency in chatbot operations. Users may be uncomfortable sharing sensitive information with chatbots if they do not know how their data are being used or who has access to it. Developers must ensure that their chatbots are transparent about how user data are collected, stored, and used. For example, chatbots that collect user data for personalized marketing must provide clear and concise information about how the data are used and allow users to opt out if they choose.
