# postgres_session
|
|
|
|
Use the `postgres_session` InSpec audit resource to test SQL commands run against a PostgreSQL database.
|
|
|
|
<br>
|
|
|
|
## 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 `postgres_session` resource block declares the username and password to use for the session, and then the command to be run:
|
|
|
|
# Create a PostgreSQL session:
|
|
sql = postgres_session('username', 'password', 'host')
|
|
|
|
# default values:
|
|
# username: 'postgres'
|
|
# host: 'localhost'
|
|
|
|
# Run an SQL query with an optional database to execute
|
|
sql.query('sql_query', ['database_name'])`
|
|
|
|
A full example is:
|
|
|
|
sql = postgres_session('username', 'password', 'host')
|
|
describe sql.query('SELECT * FROM pg_shadow WHERE passwd IS NULL;') do
|
|
its('output') { should eq '' }
|
|
end
|
|
|
|
where `its('output') { should eq '' }` compares the results of the query against the expected result in the test
|
|
|
|
<br>
|
|
|
|
## Examples
|
|
|
|
The following examples show how to use this InSpec audit resource.
|
|
|
|
### Test the PostgreSQL shadow password
|
|
|
|
sql = postgres_session('my_user', 'password', '192.168.1.2')
|
|
|
|
describe sql.query('SELECT * FROM pg_shadow WHERE passwd IS NULL;', ['testdb']) do
|
|
its('output') { should eq('') }
|
|
end
|
|
|
|
### Test for risky database entries
|
|
|
|
describe postgres_session('my_user', 'password').query('SELECT count (*)
|
|
FROM pg_language
|
|
WHERE lanpltrusted = \'f\'
|
|
AND lanname!=\'internal\'
|
|
AND lanname!=\'c\';', ['postgres']) do
|
|
its('output') { should eq '0' }
|
|
end
|
|
|
|
