Fix protocols matcher text on ssl resource docs
The `protocols` matcher section on the `ssl` resource
doc page fell victim to some copy/paste. This change
updates the text to the correct description.

title: About the ssl Resource

# ssl
Use the `ssl` InSpec audit resource to test SSL settings for the named port.
## Syntax
An `ssl` resource block declares an SSL port, and then other properties of the test like cipher and/or protocol:
describe ssl(port: #) do
it { should be_enabled }
end
or:
describe ssl(port: #).filter('value') do
it { should be_enabled }
end
where
* `ssl(port: #)` is the port number, such as `ssl(port: 443)`
* `filter` may take any of the following arguments: `ciphers`, `protocols`, and `handshake`
## Matchers
This InSpec audit resource has the following matchers:
### be
<%= partial "/shared/matcher_be" %>
### be_enabled
The `be_enabled` matcher tests if SSL is enabled:
it { should be_enabled }
### ciphers
The `ciphers` matcher tests the named cipher:
its('ciphers') { should_not eq '/rc4/i' }
or:
describe ssl(port: 443).ciphers(/rc4/i) do
it { should_not be_enabled }
end
### cmp
<%= partial "/shared/matcher_cmp" %>
### eq
<%= partial "/shared/matcher_eq" %>
### include
<%= partial "/shared/matcher_include" %>
### match
<%= partial "/shared/matcher_match" %>
### protocols
The `protocols` matcher tests what protocol versions (SSLv3, TLSv1.1, etc) are enabled:
its('protocols') { should eq 'ssl2' }
or:
describe ssl(port: 443).protocols('ssl2') do
it { should_not be_enabled }
end
## Examples
The following examples show how to use this InSpec audit resource.
### Run the ssl-benchmark example profile
The following shows how to use the `ssl` InSpec audit resource to find all TCP ports on the system, including IPv4 and IPv6. (This is a partial example based on the `ssl_text.rb` file in the `ssl-benchmark` profile on GitHub.)
...
control 'tls1.2' do
title 'Run TLS 1.2 whenever SSL is active on a port'
impact 0.5
sslports.each do |socket|
proc_desc = "on node == #{command('hostname').stdout.strip} running #{socket.process.inspect} (#{socket.pid})"
describe ssl(port: socket.port).protocols('tls1.2') do
it(proc_desc) { should be_enabled }
it { should be_enabled }
end
end
end
...
control 'rc4' do
title 'Disable RC4 ciphers from all exposed SSL/TLS ports and versions.'
impact 0.5
sslports.each do |socket|
proc_desc = "on node == #{command('hostname').stdout.strip} running #{socket.process.inspect} (#{socket.pid})"
describe ssl(port: socket.port).ciphers(/rc4/i) do
it(proc_desc) { should_not be_enabled }
it { should_not be_enabled }
end
end
end
There are two ways to run the `ssl-benchmark` example profile to test SSL via the `ssl` resource.
Clone the profile:
$ git clone https://github.com/dev-sec/ssl-benchmark
and then run:
$ inspec exec ssl-benchmark
Or execute the profile directly via URL:
$ inspec exec https://github.com/dev-sec/ssl-benchmark
