Ensuring integrity in information security is fundamentally about maintaining the accuracy and consistency of data over its entire lifecycle. This means that data should only be modified by individuals who have been granted the necessary permissions and authorization. Authorized users are typically trained and have the necessary expertise to make changes or updates to data without compromising its integrity.

If unauthorized individuals were able to alter data, it could lead to inaccuracies and potentially harmful consequences, such as errors in decision-making or loss of trust in the data. Therefore, option B correctly reflects the principle of integrity in information security, which safeguards data against unauthorized modifications, thereby preserving its original and accurate state.

In contrast, the other options suggest different practices that do not align with the concept of integrity. Allowing unrestricted access to data can lead to inappropriate modifications, while storing data offline does not inherently address integrity or security. Free sharing of data across departments, without regard for authorizations, similarly undermines the protection of data integrity.
