Data access control is a core element of a company’s security strategy, limiting the amount of confidential information that can be accessed by unauthorized parties. It can prevent the loss of corporate funds, the leakage or intellectual property, and the exposure of customer and employee personal information.

To control access to confidential data, policies must be implemented that specify the types of sensitive information to which specific employees or departments should have access. This ensures that the most relevant data will be accessed. It also prevents wasteful searching, and increases productivity.

Protecting your first-party data

Data integrity refers both to the accuracy and quality of the information. Various levels of data integrity can be protected through a combination of ensuring that only authorized users can access information, encrypting it so that it cannot be read or modified without permission and monitoring who is accessing data, when they are doing so, and how often.

Role-based access controls (RBAC): In this model, access is granted based on the individual’s role in the organization and their job function within it. This method is most effective in organizations with different levels of clearance, such as the military or law enforcement agencies.

Discretionary control of access (DAC) – In this model, the end user controls access to the resources. He or she can choose to grant their own permissions or revoke the permissions of others. However, it’s difficult to enforce and can lead to serious problems if permissions are mistakenly granted.
