Access control is a vital part of information security and is defined as the process by which you grant or deny access to your data, property, and other objects. Three elements make up access control: identification, authentication, and authorization.

What Are The Three Elements of Access Control?

The world of information security is vast. There are many different kinds of attacks and various defenses against them. One type of defense is an access control system with policies that define who has the right to do what within a given system or environment. Access control systems typically consist of identifiers (such as usernames), authentication methods (such as passwords), and authorization processes to determine whether an authenticated user should be allowed or denied access to something based on their identity and the result from the authentication process. All access control systems aim to prevent unauthorized users from accessing confidential data stored in protected computers, networks, databases, or other digital media.

Identification

Identification is the process of determining who someone is and verifying their identity. It's not always easy, especially when dealing with large groups of people in a short span of time.

Authentication

Access control limits access to information and data, depending on the person's role, identity, or authorization level. Authentication is one part of this process; it makes sure the user is who they say they are. Authentication schemes are the backbone of access control. They are responsible for verifying who you are and what you're allowed to do once authenticated.

Authorization

Authorization is the means of regulating who can access what. The two types of authorization are discretionary and mandatory. Discretionary authorizations are granted by an entity, such as an owner or administrator, to individuals based on their need to protect the resource from unauthorized access. Mandatory authorizations are granted to people with common needs while being protected from unauthorized access. The next time you consider upgrading your access control system, consider the elements we've outlined here. Some of them may be difficult to implement for your organization, and others not so much. By understanding these different features, you can decide on the best solution for your needs. Contact us at BCS Consultants to find the best option for your business.
