The majority of organizations face a major difficulty in controlling access to sensitive information. It is often associated with customer trust, which makes it even more crucial to safeguard against misuse. Data that can be used to identify an individual must be protected by policies to avoid identity fraud, the compromise of accounts or systems, and other grave consequences. To minimize the risk and reduce the possibility of harm access to sensitive information should be restricted based on role-based authorization.
There are several models that can be used to grant access to sensitive data. The simplest, discretionary access control (DAC), allows the administrator or owner to decide who can see files they own and what actions authorized users can take on them. This is the default setting in Windows, macOS and UNIX filesystems.
Role-based access control is a more durable and secure method. This model aligns privileges according to the requirements of a specific job. It also implements essential security principles, including an orderly separation of privileges, and the principle of minimum privilege.
Fine-grained access control goes beyond RBAC by allowing administrators to assign permissions in accordance with an individual’s identity. It uses a combination of something you know, for example an account number or password; something you own like an access card, keys or devices that generate codes and something that you are or have, such as a fingerprint, iris scan, or voice print. This gives you more control the control of your information and eliminates many of the common issues in authorization, including uncontrolled access by former employees, as well as access to sensitive information via applications that are third-party.
