What does a session-based authentication method typically do?

• A. Stores static user data
• B. Enables encryption of HTTP requests
• C. Places data pieces in each HTTP request header
• D. Allows open access to all resources

Answer: (C)

A session-based authentication method primarily involves placing data pieces, such as session identifiers or tokens, within each HTTP request header. This mechanism allows the server to recognize the user's session and maintain a stateful connection throughout their interaction with the application. When a user successfully authenticates, the server creates a session and generates a unique session identifier. This identifier is often stored in a cookie on the client side and sent along with subsequent requests in the HTTP header. The server then uses this session ID to retrieve user-specific data and maintain the context of the user's interactions, ensuring that access to protected resources is granted appropriately. The other options do not align with the fundamental purpose of session-based authentication. While storing static user data might be part of a broader user management approach, it does not relate directly to how authentication is managed between sessions. Encryption of HTTP requests is generally associated with securing data in transit (such as HTTPS) rather than specific to session management itself. Lastly, open access to resources is contrary to the principle of session-based authentication, which is meant to restrict access based on user identity and permissions.
