What Kinds of Access Control Systems Are There?

Jan 19

One of the three access control models that govern access to an organization's information is known as access control systems.

There are many types of access control systems designed for commercial and industrial buildings. However, based on the size and requirements of the deployment as well as the number of entry points, as well as the degree of security needed and the level of security required, not all systems are appropriate for the job. One office within an office building is an example. It requires different security procedures as compared to a hospital or large warehouse. What are the best ways to decide the access control system that is the best one for your needs?

  • Access control using discretion (DAC)

Discretionary access control is the most flexible type of access control and is therefore the least suggested for business and commercial security. Security professionals are not allowed to be granted access rights or access privileges for all users under the DAC model. Business owners are able to control their access rights and privileges. DAC isn't the most effective method of access control unless the owner of the business is knowledgeable about security rules and best practises.

  • Controlled Access is Required (MAC)

This type of access control is great for companies that require the highest levels of security and privacy. A MAC model gives a single individual (e.g., the Chief Security Officer) the responsibility of setting the criteria for access and then granting access rights to the entire enterprise. Administrators have complete control over access rights and security clearance with mandatory access control.

  • Access control basing on roles (RBAC)

This kind of access control is best suitable for businesses that need an extremely high degree of privacy and security. In a MAC model, a single person like a Chief Security Officer, is entrusted with the responsibility of defining access rules and delegate rights to the entire company. Administrators are completely in control of access rights, security clearances and mandatory access control.

  • Access control is based upon the roles (RBAC)

Permissions are determined by roles allocated to users using a role-based access-control system. In the business environment access rights are usually based on job title and employment status. For instance, managers could have full access to buildings while employees or contractors from one department only have access to the areas they require. RBAC is a straightforward architecture that lets administrators categorize users and modify rights via an online database. RBAC Systems are created to provide users with the least amount of access to allow them to accomplish their task. They follow the principles of least privilege and separation of privilege.

Access Control Software scw security cameras system

A lock and metal key are more sophisticated than security systems that are more modern. Software is needed to control access rights, verify identities and track the access privileges of users. These are the most popular access control software types:

  • Access control for the server

These systems are commonly employed in large companies and commercial structures. They rely on local servers to host software. Access control that is based on servers typically requires the purchase and renewal of software licenses, and also the upkeep of servers by an dedicated IT department. If a company requires access control at numerous locations, servers must be established at each location.

  • Access control via the internet

Access control software, sometimes referred to as embedded access control, operates through a web browser application and is connected to the LAN so that it can be accessed by any device connected to the network.

  • Cloud access control

Cloud-based access control software is distinct from the other options. It's stored on a central server, that is usually operated by a third-party and is synchronized with local ACUs on a regular basis. Because the system syncs on the cloud, cloud-based access control requires internet connectivity. When the system comes up again after an outage, the ACU will sync.

Access Control Door Readers PTZ cameras

Another aspect of access control systems is reader technology. Door readers should be installed by companies to ensure security and provide controls that permit authentication of credentials. The following are the most frequent ways to control access:

  • Readers using a keypad

To open the door, a user is required to input an PIN or passcode with keypad readers. Because there is no physical proof of identity that can be lost or stolen Keypad readers offer good security. However, users may still disclose their PIN with others and compromise the security of the building.

  • Readers to swipe cards

This door card reader can be used with badges or magnetic stripe keys cards that contain authentication data. To open the door, users swipe their cards through the reader. This type of access control system is more durable than the cards and hardware they are used for everyday use.

  • RFID readers are used to open doors

RFID technology can be used for numerous applications, including access control. RFID access control systems have data tags on their credentials that transmit signals to nearby readers. Most RFID access control systems utilize passive RFID which is also known as proxy card or proximity technology. Key cards or key fobs are typically employed in proximity-based access control systems.

  • Door readers that use biometrics

Biometric readers, which are often the most expensive type of door security reader utilize scanners to recognize people by a specific physical characteristic like a fingerprint or iris recognition. Biometrics incorporated into smartphones are an alternative to two-factor authentication within mobile access control systems using smartphones as credentials.

Types of Access Control Methods of Security Cameras system

The method used by authorized users to access the door is one of the most significant distinctions among access control systems.

Types of credentials

  • Keys in the Physical World

Every door that an authorized individual has to unlock is equipped with a key made of metal.

  • Pin codes are utilized to determine a particular kind of code

To unlock the door using keypad readers to access control devices, users need to enter a unique pin.

  • Key cards that can be used as keys

Key card lock systems for doors, one of the most used types of access control for commercial use and authentication systems, authenticate users with signals or codes that are contained on a key card. Depending on the technology, key cards may be fitted with a magnetic strip to permit swipe access control or an RFID-enabled chip that can be utilized in proximity locking systems.

  • Keychains

Due to their small size and easy to use, key fobs enable easier access to RFID systems and proximity devices. The price of key fob access control varies substantially depending on the security level and function of the credential.
