Which of the following are common signs of a potential unauthorized disclosure?

Suspicious behavior and unauthorized sharing of data are clear indicators of potential unauthorized disclosure. Such behaviors could include individuals accessing information they typically do not use, sharing sensitive data with unauthorized personnel, or acting in ways that suggest they are intentionally circumventing security protocols. Recognizing these signs is crucial for maintaining security and confidentiality as they often serve as red flags for possible breaches, either intentional or accidental.

Other options such as increased social interactions among employees, positive feedback on security measures, and regular information updates do not inherently indicate unauthorized disclosures. While these behaviors may suggest a collaborative work environment or effective security training, they do not directly point to the risks associated with data misuse or leaks. Hence, focusing on suspicious behaviors and unauthorized sharing is essential for effective risk management and detection in data security.
