What is prohibited in terms of information system use according to legal notifications?

The prohibition of unauthorized use of information systems is crucial for maintaining the security and integrity of organizational data. Unauthorized use refers to any access or use of information systems by individuals who do not have explicit permission or authority to do so. This can lead to various risks, including data breaches, theft of sensitive information, and potential legal liabilities for the organization.

Legal notifications often outline the responsibilities and restrictions imposed on users to protect the organization's information assets. These notifications are designed to ensure that all users are aware of their rights and duties regarding system access. In this context, emphasizing the need to avoid unauthorized use reinforces the idea that only those with appropriate clearance or authorization should interact with the systems.

The other options provided generally refer to activities that are acceptable or expected within the guidelines of authorized access and collaboration. Authorized use and collaboration among users are typically permitted as long as they comply with established security protocols. Accessing systems through temporary accounts may be regulated, but it is not inherently prohibited. Thus, the main focus here is on the clear and necessary prohibition of unauthorized access to safeguard information systems.
