The most important concern to address when formulating a social media policy to address information leakage is sharing company information on social media. Information leakage is the unauthorized or unintentional disclosure of confidential or sensitive information to unauthorized parties. Social media is a platform that enables the users to create and share content, such as text, images, videos, or links, with other users or the public. Sharing company information on social media is the most important concern, as it could expose the company’s trade secrets, intellectual property, customer data, financial data, or strategic plans to competitors, hackers, or regulators. Sharing company information on social media could also damage the company’s reputation, trust, or credibility, and result in legal or regulatory penalties, fines, or lawsuits. Therefore, a social media policy should clearly define what constitutes company information, and what are the rules and guidelines for sharing or not sharing company information on social media. A social media policy should also specify the roles and responsibilities of the employees, managers, and the social media team, and the consequences and sanctions for violating the policy. Sharing personal information on social media, using social media to maintain contact with business associates, and using social media for personal purposes during working hours are not as important as sharing company information on social media, as they do not directly involve the leakage of company information, and they may not have significant impact or risk on the company.
