How can you secure and control access to your OLAP cube?

Securing and controlling access to your OLAP cube is like giving the keys to a treasure chest only to those with a map – restrict access wisely, ensuring only authorized users can unlock valuable insight

As a data analyst securing an OLAP cube, the initial focus is on authentication and authorization. Authentication verifies user or application identity, while authorization determines access levels. Methods like Windows authentication, database roles, and cube roles are employed, with configurations tailored to the OLAP server and client software. This ensures a secure environment, allowing only authenticated and authorized entities to access and analyze the cube's data.

Securing your OLAP cube is super important! Make sure only the right people can access it. Use strong passwords and extra verification steps. Keep your data safe by encrypting it, like putting it in a secret code. Also, set up protective walls for your cube on the internet. Keep an eye on who's using your cube by making a list of actions. Hide sensitive info for some users (data masking) and only show them what they need (row-level security). Don't forget to update your cube regularly to fix any bugs and teach your team how to stay safe online. Follow the rules that apply to your industry and regularly check for problems. Always keep a copy of your data in case something goes wrong. Plan for disasters, like having a fire escape plan.

Securing OLAP cube to ensure only authorized people can see information based on their authorization. It can be created using Row level security and Column level security. And some cubes can also integrate with Active Directory or others. Row Level security will filter only relevant records / data in a cube based on users privilege, for example we setup row level security for [City] column where each user can only see their own data based on city level. Column level security will filter column based on each user security. For example BOD can see column sales, margin and cogs. But sales staff can only see sales without cogs field nor margin.
