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. Signed-off-by: Adam Leff <adam@leff.co>

# 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
|
