Use the `aws_iam_access_keys` InSpec audit resource to test properties of some or all IAM Access Keys.
To test properties of a single Access Key, use the `aws_iam_access_key` resource instead.
To test properties of an individual user's access keys, use the `aws_iam_user` resource.
Access Keys are closely related to AWS User resources. Use this resource to perform audits of all keys or of keys specified by criteria unrelated to any particular user.

## Syntax
An `aws_iam_access_keys` resource block uses an optional filter to select a group of access keys and then tests that group.
# Do not allow any access keys
describe aws_iam_access_keys do
it { should_not exist }
end
# Don't let fred have access keys, using filter argument syntax
describe aws_iam_access_keys.where(username: 'fred') do
it { should_not exist }
end
# Don't let fred have access keys, using filter block syntax (most flexible)
describe aws_iam_access_keys.where { username == 'fred' } do
it { should_not exist }
end
<br>
## Examples
The following examples show how to use this InSpec audit resource.
### Disallow access keys created more than 90 days ago
describe aws_iam_access_keys.where { created_age > 90 } do
it { should_not exist }
end
<br>
## Matchers
### exists
The control will pass if the filter returns at least one result. Use should_not if you expect zero matches.
# Sally should have at least one access key
describe aws_iam_access_keys.where(username: 'sally') do
it { should exist }
end
# Don't let fred have access keys
describe aws_iam_access_keys.where(username: 'fred') do
it { should_not exist }
end
## Filter Criteria
### active
A true / false value indicating if an Access Key is currently "Active" (the normal state) in the AWS console. See also: `inactive`.
# Check whether a particular key is enabled
describe aws_iam_access_keys.where { active } do
its('access_key_ids') { should include('AKIA1234567890ABCDEF')}
A true / false value indicating if the Access Key was likely created at the same time as the user, by checking if the difference between created_date and user_created_date is less than 1 hour.
# Do not automatically create keys for users
describe aws_iam_access_keys.where { created_with_user } do
A true / false value indicating if the Access Key has ever been used, based on the last_used_date. See also: `never_used`.
# Check to see if a particular key has ever been used
describe aws_iam_access_keys.where { ever_used } do
its('access_key_ids') { should include('AKIA1234567890ABCDEF')}
end
### inactive
A true / false value indicating if the Access Key has been marked Inactive in the AWS console. See also: `active`.
# Don't leave inactive keys laying around
describe aws_iam_access_keys.where { inactive } do
it { should_not exist }
end
### last_used_date
A DateTime identifying when the Access Key was last used. Returns nil if the key has never been used. See also: `ever_used`, `last_used_days_ago`, `last_used_hours_ago`, and `never_used`.
# No one should do anything on Mondays
describe aws_iam_access_keys.where { ever_used and last_used_date.monday? } do
it { should_not exist }
end
### last_used_days_ago, last_used_hours_ago
An integer representing when the key was last used. See also: `ever_used`, `last_used_date`, and `never_used`.
# Don't allow keys that sit unused for more than 90 days
describe aws_iam_access_keys.where { last_used_days_ago > 90 } do
it { should_not exist }
end
### never_used
A true / false value indicating if the Access Key has never been used, based on the last_used_date. See also: `ever_used`.
# Don't allow unused keys to lay around
describe aws_iam_access_keys.where { never_used } do
it { should_not exist }
end
### username
Searches for access keys owned by the named user. Each user may have zero, one, or two access keys.
