etc_hosts_deny resource

Use the etc_hosts_deny Chef InSpec audit resource to test rules for rejecting daemon and client traffic defined in /etc/hosts.deny.

Availability

Installation

This resource is distributed with Chef InSpec and is automatically available for use.

Version

This resource first became available in v1.39.1 of InSpec.

Syntax

An etc_hosts_deny rule specifies one or more daemons mapped to one or more clients, with zero or more options for rejecting traffic when found.

Use the where clause to match a property to one or more rules in the hosts.deny file:

describe etc_hosts_deny.where { daemon == 'value' } do
  its ('client_list') { should include ['values'] }
  its ('options') { should include ['values'] }
end

Use the optional constructor parameter to give an alternative path to hosts.deny:

describe etc_hosts_deny(hosts_path).where { daemon == 'value' } do
  its ('client_list') { should include ['values'] }
  its ('options') { should include ['values'] }
end

where

daemon is a daemon that will be rejected to pass traffic in.
client_list is a list of clients that will be rejected to pass traffic in.
options is a list of tasks that are to be done with the rule when traffic is found.

Properties

daemon

The daemon property returns a string containing the daemon that is allowed in the rule.

describe etc_hosts_deny.where { client_list == ['127.0.1.154',  '[:fff:fAb0::]'] } do
  its('daemon') { should eq ['vsftpd', 'sshd'] }
end

client_list

The client_list property returns a 2d string array where each entry contains the clients specified for the rule.

describe etc_hosts_deny.where { daemon == 'sshd' } do
  its('client_list') { should include ['192.168.0.0/16', '[abcd::0000:1234]'] }
end

options

The options property returns a 2d string array where each entry contains any options specified for the rule.

describe etc_hosts_deny.where { daemon == 'sshd' } do
  its('options') { should include ['deny', 'echo "REJECTED"'] }
end
