Discretionary Access Control (DAC)

An access control model where data owners define permissions for resources.

Understanding DAC

DAC operates using Access Control Lists (ACLs) or user/group permissions. The resource owner can modify access rights based on their needs, providing flexibility but also increasing the risk of privilege abuse.

Key Features of DAC

Owner-Controlled Permissions – Users determine who can access their resources.
User-Centric Security – Access rights are granted on an individual or group basis.
Flexible but Risky – Misconfigured permissions may expose sensitive data.

Best Practices for Implementing DAC

Enforce Least Privilege – Users should have only the minimum permissions necessary.
Regular Access Reviews – Continuously audit and remove unnecessary permissions.
Use Multi-Factor Authentication (MFA) – Enhances security against unauthorized access.
