What are the three strategies that can be used to authenticate a user to a computer system?
The list below reviews some common authentication methods used to secure modern systems.
- Password-based authentication. Passwords are the most common methods of authentication.
- Multi-factor authentication.
- Certificate-based authentication.
- Biometric authentication.
- Token-based authentication.
What is an authentication mechanism explain in detail?
Authentication mechanisms are modules that authenticate the user with a specific challenge or authentication technology, such as user name and password and one-time password. The order on which the authentication mechanisms are run is controlled by an authentication policy.
How do you understand authentication?
In authentication, the user or computer has to prove its identity to the server or client. Usually, authentication by a server entails the use of a user name and password. Other ways to authenticate can be through cards, retina scans, voice recognition, and fingerprints.
What happens when you do not specify an authentication mechanism?
Basic authentication is the default when you do not specify an authentication mechanism. When basic authentication is used, the following actions occur: A client requests access to a protected resource. The web server returns a dialog box that requests the user name and password.
How does a web server authenticate a client?
With client authentication, the web server authenticates the client by using the client’s public key certificate. Client authentication is a more secure method of authentication than either basic or form-based authentication. It uses HTTP over SSL (HTTPS), in which the server authenticates the client using the client’s public key certificate.
How does certificate based mutual authentication work in Java?
When using certificate-based mutual authentication, the following actions occur. A client requests access to a protected resource. The web server presents its certificate to the client. The client verifies the server’s certificate. If successful, the client sends its certificate to the server. The server verifies the client’s credentials.
How to specify an authentication mechanism in Java?
To specify an authentication mechanism, use the login-configelement. It can contain the following subelements. The auth-methodsubelement configures the authentication mechanism for the web application. The element content must be either NONE, BASIC, DIGEST, FORM, or CLIENT-CERT.
