How does the module ensure confidentiality of client information?

The module ensures confidentiality of client information primarily through restricted access and encrypted data storage. Restricted access is vital as it means that only authorized individuals can view or manipulate sensitive client data, thereby reducing the risk of unauthorized access and potential breaches. Additionally, encrypted data storage plays a crucial role in protecting the information by transforming it into an unreadable format for anyone without the appropriate decryption key. This dual approach—limiting who can access the data and safeguarding the data itself—creates a robust framework for maintaining client confidentiality.

While limiting the number of users accessing data can contribute to confidentiality, it is not as comprehensive as employing encryption and implementing access restrictions. Physical locks on files might address the physical security of paper documents but are not applicable in the digital context of most modules. Lastly, requiring frequent password changes enhances security but does not directly address data confidentiality in the same way that access restrictions and encryption do. Therefore, the combination of these strategies in the correct choice effectively safeguards client information.
