What is Data Security?

We take security seriously at JTA. A lot of data science studies use large data sets for patterns without any consideration for security. We manage large sets of data with security in mind. Especially in the experimental phases of analysing the data. Often we follow the experimental phase by building a product that will allow a business to leverage the insight. Security is important in these products. JTA can build dashboards that adapt their content depending on who is viewing it. This helps our clients comply with corporate accountability legislation.

Data visualization platforms all come with built-in security features. Because these platforms are unaware of the format of the data that they will show, the security features are often rudimentary and cannot decide access permissions based on the detail in the data.

When a business requires a highly customisable, data-driven, approach to security we can embed the access control into the data analysis layer and switch off the mechanisms in the visualization platform. The data analysis layer will treat access as a calculated metric just like any other metric but the result is one of two values: Show or Hide.

This means that we can allow for sophisticated rules such as geo-filtering whereby users can only see data for their location or department.

The Secret Recipe For Success

  • Consider where the data storage and how security definitions. Allow layered security where we can control access by the report, report item, row, column and cell.
  • Try to use pre-existing tables of security definitions maintained in a legacy system. Adding new users and revoking permissions as employees leave or change roles is a very time-consuming process. We always recommend synchronising access tables from legacy systems before inventing new definitions.
  • Where possible, determine a user’s access permissions by calculation. For example, combining an employee’s location, department, seniority and title from human resources data using well-defined rules can control security. This negates the need to implement a new business process to set security levels and respond to access requests.
