+====== Enhance Plesk Security by Enabling TLS 1.3 ======
+You can enhance Plesk's security features by enabling TLS 1.3 and disabling weak cipher suites.
+By default, Plesk configuration enables TLS1.0 , TLS1.1 and TLS1.2. This guide will show you how to enable TLS 1.3.

+This guide is made and tested on Plesk 17.8 and Centos 7.5. For Debian/Ubuntu Plesk ,configuration files should be located in ''/etc/apache2/mods-available/ssl.conf''.
