How should you store large amounts of sensitive data in OutSystems?

Storing large amounts of sensitive data securely is critical, especially in mobile applications where data can be vulnerable to unauthorized access. Encrypting all local storage is the most appropriate approach for managing sensitive data in OutSystems.

When data is encrypted, it transforms into a secure format that is unreadable without the appropriate decryption key. This means that even if an unauthorized individual gains access to the device’s storage, they would not be able to interpret the data without the key, thereby significantly mitigating the risk of data breaches.

The option of storing data in plain text or without encryption would leave the data exposed and easily accessible to anyone who gains access to the device or the storage medium, posing a significant security risk. Similarly, relying solely on device-specific storage without encryption also presents vulnerabilities, as data can still be extracted if the device is compromised.

While storing sensitive information only on remote servers might seem secure, it depends heavily on the security protocols of the server. In many scenarios, applications require offline access to data, thus making local encrypted storage a necessity. Therefore, encrypting all local storage provides a balanced solution for keeping data secure while allowing for necessary access when on the go.
