The most appropriate solution to prevent privacy violations due to information exposure through error messages is to create default error pages or messages that do not include variable data. This practice ensures that sensitive information is not inadvertently displayed to users in the event of an error. Displaying detailed error messages can expose system information or user data, potentially leading to security and privacy risks.
According to IAPP guidelines, handling errors in a way that minimizes the exposure of sensitive data is critical for maintaining privacy and security. By using generic error messages, the risk of information leakage is significantly reduced.
