Securing Transmission and Storage of Sensitive Data
When developing a software that involves transmitting sensitive data, such as passwords, in a client/server configuration, it is crucial to prioritize security. In this article, we will explore the best practices for ensuring a fully secure transmission and storage of data.
Secure Connection
Without proper transport level security, it is not possible to secure an application against man-in-the-middle attackers. It is essential to establish a secure connection between the client and the server, using protocols like TLS (Transport Layer Security). This ensures both encryption and authentication, protecting the data from unauthorized access.
Transmission of Passwords
Once a secure connection is in place, there is no need to hash or encrypt the password before sending it. The secured connection provides the necessary protection for transmitting the password as is. It is important to note that using bcrypt or any other hashing algorithm for transmission does not enhance security in this scenario.
Secure Storage
To protect against database compromises, it is crucial to store passwords securely. Instead of storing plaintext passwords, it is recommended to store bcrypted passwords in the database. BCrypt is a strong hashing algorithm that adds an extra layer of security, making it extremely difficult for attackers to retrieve the original password even if the database is compromised.
By following these best practices, you can ensure a fully secure transmission and storage of sensitive data in your client/server configuration. Prioritizing security measures like secure connections and password storage can greatly enhance the overall security of your application.
