+====== 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.
-This guide will show you how to enable TLS 1.3.

+===== Enabling TLS1.3 =====
+Edit the file ''/etc/httpd/conf.d/ssl.conf''.
+Find the following line and comment out (you can use # ):
+<code><IfModule mod_ssl.c>
+SSLProtocol +TLSv1 +TLSv1.1 +TLSv1.2
+SSLCipherSuite HIGH:!aNULL:!MD5
+</IfModule></code>
-. Edit file ''/etc/httpd/conf.d/ssl.conf''.
+Replace it with:
+<code><IfModule LiteSpeed>
+SSLProtocol TLSv1.1 TLSv1.2 TLSv1.3
+SSLCipherSuite HIGH:!aNULL:!MD5
+</IfModule></code>
+This enables TLS1.1 , TLS1.2 and TLS1.3

-Find following lines:
+If you want to disable TLS1.1 as well, then change the line to:
-<code>SSLProtocol +TLSv1 +TLSv1.1 +TLSv1.2</code>
-Replace first line to the following:
-<code>SSLProtocol TLSv1.1 TLSv1.2 TLSv1.3</code>
-This is enables TLS1.1 , TLS1.2 and TLS1.3
-so in case if you want to disable TLS1.1 as well, then make it:
 <code>SSLProtocol TLSv1.2 TLSv1.3</code>
+===== Disable Weak Cipher Suites (Optional) =====
