In an era where security is paramount, access control systems have emerged as a fundamental tool for safeguarding various spaces.

From homes to businesses, access control systems provide a sense of security and control over who can enter a premise and when.

Here’s everything you need to know about access control systems for securing your property.

Understanding Access Control Systems

They employ electronic means to grant or deny access, enhancing security and enabling efficient monitoring. These systems ensure that only authorized personnel can enter specific spaces, bolstering overall safety.

Types of Access Control Systems

Discretionary Access Control (DAC)

Mandatory Access Control (MAC)

MAC uses security labels and levels to control access. Access decisions are based on clearances and authorizations, often used in government and military settings.

Role-Based Access Control (RBAC)

Access permissions are linked to roles and not individuals. This model is prevalent in organizations and simplifies administration.

Rule-Based Access Control (RBAC)

RBAC uses rules to determine access, combining attributes to make decisions. It is flexible and efficient for dynamic organizations.
