-====== Enhance Plesk Security by Enabling TLS 1.3 ======
+~~REDIRECT>https://docs.litespeedtech.com/lsws/cp/plesk/configuration/#enable-tls13~~
-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''.

-===== 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>
-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
-{{:litespeed_wiki:plesk:plesktls13-2.png|}}
-If you want to disable TLS1.1 as well, then change the line to:
-<code>SSLProtocol TLSv1.2 TLSv1.3</code>
-===== Disable Weak Cipher Suites (Optional) =====
-{{:litespeed_wiki:plesk:plesktls13-3.jpg|}}
-By default, Plesk also comes with some weak cipher suites. If you want to disable them, find the following line:
-<code>SSLCipherSuite HIGH:!aNULL:!MD5</code>
-And replace it with:
-<code>SSLCipherSuite TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256:TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384:TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256:TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA:TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384:TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA:TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA:TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA</code>
