BASIC AUTHENTICATION Meaning and
Definition
-
Basic authentication is a method of validating the identity of a user or a client requesting access to a system or resource. It is a simple and widely used form of authentication in computer networks and web applications.
In basic authentication, the user's credentials, usually a username and password, are sent as plain text over the network. When the user makes a request to access a secure resource, such as a protected webpage or an API endpoint, the client software or web browser prompts the user to enter their credentials. The entered credentials are then simply encoded in Base64 and included in the HTTP headers of the request.
Upon receiving the request, the server extracts the credentials from the request headers and verifies their validity by comparing them against a pre-determined user database. If the provided credentials match an existing user's credentials, the server grants access to the requested resource.
While basic authentication is widely supported and easy to implement, it has several limitations. The main drawback is that the credentials are transmitted in plain text, which makes them vulnerable to interception and unauthorized access. Additionally, basic authentication does not provide any protection against replay attacks or session hijacking.
Overall, basic authentication offers a basic level of security for simple applications but is not recommended for sensitive or high-security systems. It is commonly used in scenarios where the risk of interception is low or when used in conjunction with other security measures such as HTTPS.
