A healthcare company needs to ensure the privacy of its patients' health records. When deploying a new online patient portal, which measure is most effective for protecting the privacy of health records while they are being accessed and transmitted through the portal?
Applying data masking techniques to the records before storage
Encrypting data in transit
Requiring multi-factor authentication for user access to the portal
Implementing geographic restrictions on where the health records can be accessed
Encrypting data in transit is the most effective measure because it prevents unauthorized parties from intercepting and reading health information as it travels over the network. Data masking mainly protects data in storage or non-production environments, geographic restrictions primarily address legal or compliance boundaries, and multi-factor authentication verifies user identity but does not protect the content of data packets during transmission.
