Should User Information and Credentials Be Separated for Enhanced Security?

Secure Storage of User Information and Credentials

Regarding the optimal method for storing user information, it has been suggested to segregate personal data from login credentials into separate database tables. However, considering best practices for data security and redundancy, it may be prudent to reconsider this approach.

Avoid Storing Passwords

It is crucial to emphasize that storing passwords in plain text is a security risk. In the event of a data breach, passwords can be compromised, exposing users to unauthorized account access. Instead, it is recommended to store hashed password values using a robust hashing algorithm, such as bcrypt, which incorporates salting for added security.

Keep Sensitive Data Together

While it may seem logical to separate login information from personal data for security purposes, this approach does not offer significant additional protection. If one table is compromised, it is relatively straightforward to access other tables within the same database.

Consider External Data Storage

For enhanced security, it may be beneficial to store user credentials in a separate data store from the domain data. LDAP directory servers are commonly used for this purpose, providing centralized credential management and facilitating single-sign-on capabilities. This approach helps mitigate the risk of unauthorized access to both user information and login credentials in case of a data breach.
