What must a legal notification inform users regarding information system usage?

A legal notification regarding information system usage must inform users that their activities may be monitored or recorded. This transparency is crucial for establishing user awareness about the extent of oversight present within the information system. By notifying users, organizations can ensure compliance with legal obligations and maintain a level of accountability among users regarding their actions while accessing system resources.

This notification serves multiple purposes: it enables informed consent from users, aligns with privacy regulations, and helps deter potential misuse of the system. When users are aware that their actions are subject to monitoring, they are more likely to adhere to acceptable use policies and understand the importance of security practices.

The other options do not accurately reflect best practices or legal requirements for user notification. Users should not be led to believe they can act without authorization, as this undermines security protocols. Additionally, while information systems may indeed be protected by various laws, simply stating that does not fulfill the requirement of notifying users about the monitoring of their activities. Lastly, conveying that user sessions cannot be audited contradicts the very purpose of monitoring and accountability in information system usage.
