MS SQL - Privacera Data Access - Evaluation Sequence

MS SQL - Privacera Data Access - Evaluation Sequence

This topic steps through a test sequence intended to help confirm Privacera Data Access and policy-based controls for an MS SQL Server.

Install MS SQL CLI

mssql-cli is a command line query tool for MS SQL Server.  It runs on Windows, macOS, and Linux.

For more general information and detailed installation instructions see Microsoft Docs / SQL / Tools / Command prompt utilities / mssql-cli.

For macOS and Windows platforms you can generally install using pip.

$ pip install mssql-cli

On AWS/CentOS /RHEL flavored systems use sudo to first install python-pip, then use pip.

sudo yum install -y python-pip
sudo pip install mssql-cli

For Ubuntu flavor Linux,  use apt-get:

# Import the public repository GPG keys
curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -

# Register the Microsoft Ubuntu repository
sudo apt-add-repository https://packages.microsoft.com/ubuntu/18.04/prod

# Update the list of products
sudo apt-get update

# Install mssql-cli
sudo apt-get install mssql-cli

# Install missing dependencies
sudo apt-get install -f

Create Test Database and Content

Login as Administrator or user with sufficient privileges to create and populate a database.
mssql-cli -S ${MSSQL_SERVER_NAME}.database.windows.net -d${DATABASE} -U${ADMIN_USER} 

mssql-cli

SELECT * FROM customer_schema.customer_data;

Create a client 'Users'

Log into Privacera Portal.

In Privacera Portal Access Management: Users/Groups/Roles:

  1. Create Role "Sales_Role".

  2. Create User "Emily" and make Emily part of the Sales_Role.

Test Use Cases

1. Confirm the ability to log on to the Customer database as user 'emily'. 

mssql-cli -S ${MSSQL_SERVER_NAME}.database.windows.net -d${DATABASE} -U${USER}
# For example : mssql-cli -S test.database.windows.net -d customer -U emily 

Evaluate Privacera Access Control

In Privacera Portal: Access Management: Resource Policies, open the privacera_mssql application (in the MSSQL System).

Confirm policy "all - database, schema, table, column" is in place and defined.

Return to your mssql client and confirm access by user emily.  While logged in as 'emily', select from customer database. 
select * from customer_schema.customer_data;

Return to Privacera Portal: Access Management: Resource Policies, privacera_mssql application, open the policy 'all - database, schema, table, column' for to edit.    Disable this policy.

Return to the mssql client and attempt the selection.  This selection should fail. 
select * from customer_schema.customer_data;
