aws_efs_file_systems resource

Use the aws_efs_file_systems InSpec audit resource to test the properties of some or all AWS EFS file systems. To audit a single EFS file system, use aws_efs_file_ststem (singular).

This resource is added to InSpec AWS resource pack in version 1.10.0 and it is available with InSpec 4.18.108 and later versions.

Syntax

An aws_efs_file_systems resource block collects a group of EFS file system descriptions and then tests that group.

describe aws_efs_file_systems
  it { should exist }
end   

Parameters

This resource does not require any parameters.

Properties

tags

The list of tags that the EFS file system has.

names

The value of the Name (case sensitive) tag if it is defined.

file_system_ids

The ID of the EFS file system.

creation_tokens

The creation token that the EFS file system is associated.

owner_ids

The owner id of the EFS file system.

entries

Provides access to the raw results of the query, which can be treated as an array of hashes.

creation_times

The creation time of the EFS file system.

performance_modes

The performance mode of the EFS file system, e.g. ‘maxIO’.

encryption_status

This indicates whether the EFS file system is encrypted or not.

throughput_modes

The throughput mode of the EFS file system.

kms_key_ids

The ID of an AWS Key Management Service (AWS KMS) customer master key (CMK) that was used to protect the encrypted EFS file system.

size_in_bytes

The latest known metered size (in bytes) of data stored in the file system, in its value field.

life_cycle_states

The life cycle phase of the EFS file system, e.g. ‘deleting’.

Examples

Ensure you have exactly 3 file systems:

describe aws_efs_file_systems do
  its("entries.count") { should cmp 3 }
end

Use this InSpec resource to request the IDs of all EFS file systems, then test in-depth using aws_efs_file_system:

aws_efs_file_systems.file_system_ids.each do |file_system_id|
  describe aws_efs_file_system(file_system_id) do
    its("tags") { should include("companyName" => "My Company Name") }
    it { should be_encrypted }
    its("throughput_mode") { should eq "bursting" }
    its("performance_mode") { should eq "generalPurpose" }
  end
end

Matchers

exist

The control will pass if the describe returns at least one result.

Use should_not to test the entity should not exist.

describe aws_efs_file_systems.where( <property>: <value>) do
  it { should exist }
end

describe aws_efs_file_systems.where( <property>: <value>) do
  it { should_not exist }
end

AWS Permissions

Your AWS principal will need the EFS:Client:DescribeFileSystemsResponse action with Effect set to Allow.
