Types of Access Control systems:

There are many different types of access control systems for commercial buildings and businesses, but not all systems will be the right fit, depending on the size of the deployment, the number of users and entries, and the level of security required. So, how do you know which access control system is best for your space? Find below some control systems depending on the use:

  • Discretionary access control (DAC): Discretionary access control is the least restrictive, and therefore the least recommended type of access control for commercial and business security. The DAC model gives business owners, rather than security experts, control over access rights and permissions for all users. Unless the business owner is well-versed in security policies and best practices, DAC is not the best type of access control model.
  • Mandatory access control (MAC): This type of access control is best-suited for organizations that require high security and confidentiality. Within a MAC paradigm, one person is given authority to establish access guidelines and assign permissions for the entire organization, such as a Chief Security Officer. Mandatory access control gives the administrator sole discretion over access permissions and security clearance.
  • Role based access control (RBAC): A role based access control paradigm defines permissions by roles assigned to users in the system. Within a business setting, access privileges are often based on employment status and job title, such as allowing management full building access, while contractors or employees from a specific department will only have access to the spaces they need to do their work. RBAC is a user-friendly model, and allows administrators to group users and adjust permissions from a central database. RBAC systems usually employ the principles of least privilege and separation of privilege, where users are compartmentalized and given the minimum level of access required to perform their job.
Types of Access Control Methods

One of the biggest differentiators between access control systems is how authorized users unlock the door. The type of credentials supported by an access control system also affects the capabilities and security of the system, as well as factors into the cost of the system. Not all access control systems can support every type of credential.

  • Biometrics credentials: are often used in access control systems in high-security spaces. Technology including fingerprint readers, facial recognition, and iris scanning are common examples of biometric access control. Biometrics can also be used as a form of two-factor authentication, requiring users to present a key card, fob, or mobile credential, as well as complete a biometric scan in order to unlock the door.
  • Physical Keys: are the most basic form of access control requires authorized individuals to carry a metal key for each door they need to unlock.Pin codes. With keypad reader access control systems, users have to enter a unique PIN code to unlock the door.
  • Key cards: are One of the most common types of commercial access control, key card door lock systems use signals or code embedded in a key card to authenticate users. Depending on the system, key cards can include a magnetic strip for swipe access control systems, or use an RFID activated chip for a proximity door lock system.
  • Mobile credentials: With this type of access control, a user’s smartphone is their key. Usually app-based, mobile credentials allow users to unlock the door by tapping a button inside an app, and often support additional access methods such as Apple Watch and tablet apps. Mobile access control systems that use Wi-Fi, Bluetooth and cellular data also have the ability to support touchless and proximity-based unlocking.
