# login_defs
|
|
|
|
Use the `login_defs` InSpec audit resource to test configuration settings in the `/etc/login.defs` file. The `logins.defs` file defines site-specific configuration for the shadow password suite on Linux and Unix platforms, such as password expiration ranges, minimum/maximum values for automatic selection of user and group identifiers, or the method with which passwords are encrypted.

## Availability
|
|

### Installation
|
|
|
|
This resource is distributed along with InSpec itself. You can use it automatically.
|
|
|

### Version
|
|
|
|
This resource first became available in v1.0.0 of InSpec.
|
|
|
|
## Syntax
|
|
|
|
A `login_defs` resource block declares the `login.defs` configuration data to be tested:
|
|
|
|
describe login_defs do
|
|
its('name') { should include('foo') }
|
|
end
|
|
|
|
where
|
|
|
|
* `name` is a configuration setting in `login.defs`
|
|
* `{ should include('foo') }` tests the value of `name` as read from `login.defs` versus the value declared in the test
|
|

|
|
### Test password expiration settings

|
|
|
describe login_defs do
|
|
its('PASS_MAX_DAYS') { should eq '180' }
|
|
its('PASS_MIN_DAYS') { should eq '1' }
|
|
its('PASS_MIN_LEN') { should eq '15' }
|
|
its('PASS_WARN_AGE') { should eq '30' }
|
|
end
|
|
|
|
### Test the encryption method

|
its('ENCRYPT_METHOD') { should eq 'SHA512' }
|
|
end
|
|
|
|
### Test umask setting
|
|
|
