What is HTTP basic authentication header?
HTTP basic authentication is a simple challenge and response mechanism with which a server can request authentication information (a user ID and password) from a client. The client passes the authentication information to the server in an Authorization header. The authentication information is in base-64 encoding.
Is basic authentication over HTTP Secure?
Note: The HTTP basic authentication scheme can be considered secure only when the connection between the web client and the server is secure. If the connection is insecure, the scheme does not provide sufficient security to prevent unauthorized users from discovering the authentication information for a server.
Does HTTP headers support authentication?
HTTP supports the use of several authentication mechanisms to control access to pages and other resources. These mechanisms are all based around the use of the 401 status code and the WWW-Authenticate response header. However, the authentication is per connection and will only work with HTTP/1.1 persistent connections.
Can a CSRF attack be prevented by SSL?
Moreover, using SSL does not prevent a CSRF attack, because the malicious site can send an “https://” request. Typically, CSRF attacks are possible against web sites that use cookies for authentication, because browsers send all relevant cookies to the destination web site. However, CSRF attacks are not limited to exploiting cookies.
Do you need CSRF protection for bearer scheme authentication?
Yes, you don’t need CSRF protection when using a bearer scheme authentication as the browser does not automatically add the Authorization header to the request. You do need CSRF protection for cookies, basic, Windows, digest and client certificates authentication schemes as these are automatically added by the browser.
Which is an example of a CSRF attack?
Cross-Site Request Forgery (CSRF) is an attack where a malicious site sends a request to a vulnerable site where the user is currently logged in. Here is an example of a CSRF attack: A user logs into www.example.com using forms authentication. The server authenticates the user. The response from the server includes an authentication cookie.
How is CSRF vulnerability relies on authenticated session management?
In fact, the CSRF vulnerability relies on the authenticated session management. Typically, session management in a web application is based on cookies. With each request to the server, the browser sends the related cookie that identifies the current user’s session.
