A systems administrator disabled TLS 1.0 and 1.1, as well as RC4, 3DES, and AES-128 ciphers for TLS 1.2, on a web server. A client now reports being unable to access the web server, but the administrator verifies that the server is online, the web service is running, and other users can reach the server as well. Which of the following should the administrator recommend the user to do FIRST?
The issue arises because the systems administrator disabled older TLS versions (1.0 and 1.1) and deprecated weaker ciphers (RC4, 3DES, AES-128) on the web server. This security enhancement is necessary to protect against vulnerabilities, but older web browsers may not support the newer TLS versions or stronger ciphers. Therefore, updating the web browser to the latest version would ensure compatibility with the more secure configurations on the server.
D is correct. The problem is that the browser doesn't support the latest standards.
D. Update the web browser to the latest version.
