How it was found

Summary

Websites using TLS 1.0 will be considered non-compliant by PCI after 30 June 2018.

Description

TLS 1.0 has several flaws. An attacker can cause connection failures and they can trigger the use of TLS 1.0 to exploit vulnerabilities like BEAST (Browser Exploit Against SSL/TLS).

Steps To Reproduce

-Nginx, locate any use of the directive ssl_protocols in the nginx.conf file and remove TLSv1.

ssl_protocols TLSv1.1 TLSv1.2;

-Configure your web server to disallow using weak ciphers. You need to restart the web server to enable changes.
