Matchers
This InSpec audit resource has the following special matchers. For a full list of available matchers, please visit our Universal Matchers page.
The controls will pass if the describe method returns at least one result.
exist
Use should to test that the entity exists.
describe aws_ec2_network_interface(network_interface_id: 'NETWORK_INTERFACE_ID') do
it { should exist }
end
Use should_not to test the entity does not exist.
describe aws_ec2_network_interface(network_interface_id: 'NETWORK_INTERFACE_ID') do
it { should_not exist }
end
be_available
Use should to check if the entity is available.
describe aws_ec2_network_interface(network_interface_id: 'NETWORK_INTERFACE_ID') do
it { should be_available }
end
AWS Permissions
Your Principal will need the EC2:Client:DescribeNetworkInterfacesResult action with Effect set to Allow.
