So, to disable this protocol follow the given steps. Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Server' -name 'Enabled' -value '0' –Type 'DWORD' The easiest way to disable TLS 1.0 is via Internet Properties.

Nmap -script ssl-enum-ciphers -p 443 | grep TLSv If not, consider creating your own config file with your SSLProtocol settingĪnd including it in this first virtual host config, and possibly all virtualĪs mentioned by others, the configuration you want is SSLProtocol TLSv1.2Īfter you make your change, you can quickly confirm it via: systemctl reload apache2 Otherwise, it's likely that setting it in your ssl.conf file would work.ĭ. If not, but you find it includes a config file that is setting SSLProtocol,Ĭ. If you find that config file explicitly sets SSLProtocol, make your change there.ī. Inspect the configuration for that virtual host carefully.Ī. Determine the first virtual host on the given port. For example, if you've used the Let's Encrypt installer, it often adds these: This can be important if your configuration has Include directives. In that time, TLS has protected billions and probably trillions of connections from eavesdropping and attack. TLS 1.0 will be 20 years old in January 2019. On the Internet, 20 years is an eternity. When you see this, you might find that it's sufficient to update the SSLProtocol config for just that "default server" virtual host.Īnother complication that you might run in to with earlier suggestions is that if you grep for occurrences of SSLProtocol in your /etc/apache2/ or /etc/httpd/ tree, you will not find configuration in other parts of your file system. In March of 2020, Firefox will disable support for TLS 1.0 and TLS 1.1. Surely, before disabling weak versions of SSL / TSL protocols, you will want to make sure that you can use the TLS 1.2 protocol on your system. Port 443 namevhost (/etc/apache2/sites-enabled/:2) Hi, in this post, I want to show you how to disable the weak versions of the Transport Layer Security (TLS) and Secure Socket Layer (SSL) protocols using Windows PowerShell. Port 443 namevhost (/etc/apache2/sites-enabled/:2) When you do this you should see a list of the virtual hosts and it might include a 443 section something like *:443 is a NameVirtualHostĭefault server (/etc/apache2/sites-enabled/:2) On CentOS, only one line will probably be needed: httpd -t -D DUMP_VHOSTS To determine the first virtual host: bash even if its configuration doesn't explicitly specify a SSLProtocol value. The following suggestions were tested on Ubuntu 16.04 Apache 2.Ī key observation is that the first virtual host on that port dictates the setting. There are a lot of fine answers here, but they did not work for me or were actually overkill. Once TLS 1.0/1.1 are disabled, New Relics ingest tier can no longer accept connection requests via the disabled protocol versions, and thus cannot generate. ![]()
