Data access control, which limits the amount confidential information that is accessible by unauthorized parties, is a key element of a security strategy. It can help to prevent leaks of intellectual property, exposure of customers’ and employees’ personal information, and loss of corporate funds.
Controlled access involves implementing policies which dictate the types of sensitive data that specific employees and department must have access too. This ensures only the most relevant information is accessed, preventing wasted searches and ensuring productivity.
Protecting first-party data
Data integrity refers to the quality of information and its correctness. Data integrity is protected in different ways. For example, only authorized users are allowed to access the data. It can also be protected by encrypting information so that no one can read it or modify it without permission.
Role based access controls (RBACs): This model allows access to be granted based on a person’s role within an organization and their job functions. This method is most effective in organizations with different levels of clearance, such as the military or law enforcement agencies.
Discretionary (or discretionary) access control: In this model access to a resource is controlled by the user. They have the freedom to grant or revoke their own permissions. It’s hard to enforce, and can cause serious problems if permissions were granted in error.
