Introduction

Data access control (DAC) is a mechanism for managing data access permissions. DAC sets permissions for specific users or groups to access data, ensuring data confidentiality and security. Access permissions are usually assigned by the data owner and are based on criteria that allow or restrict access to the data.

Applicable Scene

Used to manage internal company data, set different access rights for each employee, and prevent information leakage and unauthorized access. DAC is widely used in cloud-based systems that need to set appropriate permissions for data accessed by external users. Protect sensitive information and maintain data integrity by setting access rights for specific users in the database. When managing sensitive patient information in hospitals and medical institutions, protect privacy by setting different access rights for different medical staff.

Pros: Controlling access to data reduces the risk of unauthorized access and information leakage. Since you can set detailed permissions for each user and group, you can control access rights according to your business. Easily implement necessary access controls to comply with laws and regulations on personal information protection and data security. By limiting access to unnecessary data, you can prevent unnecessary consumption of system resources.

Cons: In large systems and environments with many users, permission settings and management can be complex. Effective permission management requires administrators to invest time and effort, and in some cases requires specialized tools and systems. Misconfigured permissions or incorrect operations can lead to unexpected access restrictions and security degradation. Excessive access controls can prevent some users from accessing the data they need, affecting business efficiency.
