Understanding the Basics: What Are the 3 Types of Access Control?

Access control systems are essential today, and when physical and cyber security matters, people should know about them differently. These systems are made to have power over who enters into some place or access certain information, thus ensuring that assets and data are kept secure. The two different ways used include deciding on one’s own called Discretionary Access Control (DAC), making it mandatory, known as Mandatory Access Control (MAC), and limiting entry according to what role someone holds, called Role-Based Access Control (RBAC). Each has unique qualities that suit its needs when dealing with security issues within an organization.

The Most Common Types of Access Control Systems

These systems help provide security-sensitive information by determining which persons can access a particular resource. The three common types of access control systems include Mandatory Access Control (MAC), Discretionary Access Control (DAC), and Role-Based Access Control (RBAC). Each has its unique features and benefits to meet varying safety requirements.

Mandatory Access Control (MAC)

Mandatory Access Control (MAC) offers the most substantial level of security, as only administrators have ownership to grant or deny access to resources within the system. No user can change permissions. Hence, the system is safeguarded from sensitive areas.

In MAC, resource owners cannot grant access to anything in the system. Each user is assigned unique variables that form a digital security profile, determining their level of access. Due to its concern for detail in securing data, MAC works well in environments that require utmost confidentiality, like government agencies.

Discretionary Access Control (DAC)

Discretionary Access Control (DAC) allows resource managers to permit whomever they wish. However, DAC’s existing limitation is that it requires consistent monitoring because controlling authorities may make errors in granting access rights. On the contrary, the Multilevel access control (MAC) system is rigid and does not require much effort.

Role-Based Access Control (RBAC)

Role-based access Control (RBAC) is an approach to restricting system access to authorized users. The system ensures employees can only view information within their job description and responsibility limits.

Organizing access rights in RBAC is based on organizational job descriptions, among other business factors. It allows users with similar privileges to be grouped, simplifying the permissions management process. Human resource staff can access marketing files or databases without access to marketing files or databases, and vice versa. RBAC offers a lightweight, scalable, and flexible approach, leading to increased transparency and control over data loss prevention practices and maintaining a fortified position against cyber-security breaches and threats.
