Which of the following practices helps secure access to sensitive data?

Shredding documents when they are no longer needed is a critical practice in securing access to sensitive data. This action ensures that sensitive information is permanently destroyed, making it inaccessible to unauthorized individuals. Retaining paper documents that contain confidential information poses a risk of data breaches or leaks if those documents are left unattended or discarded improperly. By shredding, organizations effectively minimize the chances of accidentally exposing sensitive information, thus enhancing their overall data security.

Other practices mentioned, such as leaving sensitive documents on desks or providing open access to data for all employees, increase the risk of unauthorized access. Similarly, posting password reminders on monitors can compromise account security, as it makes it easier for someone to retrieve sensitive information without permission. These contrasting approaches underscore the importance of adopting practices, like shredding, that directly contribute to the safeguarding of sensitive data.
