In the ever-evolving landscape of security technology, biometric access control has emerged as a cutting-edge solution that promises to revolutionize the way we protect our places of business. This technology, which utilizes unique physical or behavioral traits for authentication, has gained substantial attention across the access control industry. However, like any innovation, biometric access control comes with its own set of advantages and disadvantages.

Pros of Biometric Access Control

• Enhanced Security

One of the most significant advantages of biometric access control is its unparalleled security level. Unlike traditional methods such as passwords or keycards, biometric traits like fingerprints, iris patterns, or facial features are nearly impossible to replicate. This dramatically reduces the risk of unauthorized access and identity fraud.

• Convenience and Speed

Biometric authentication eliminates the need to remember complex passwords or carry physical tokens. Users can gain access simply by presenting their unique traits, making the process nearly effortless. With most biometric access control, all you need to bring is yourself.

• Non-Transferable

Unlike keycards or passwords that can be shared or stolen, biometric traits are inherently tied to the individual. This non-transferable nature ensures that only authorized personnel can access restricted areas.

• Accuracy and Reliability

Biometric systems offer a high level of accuracy and reliability. False positives and false negatives are minimized due to the uniqueness of the biometric traits being used. This accuracy contributes to a robust and dependable security infrastructure.

• Audit Trails

Biometric access control systems often come equipped with audit trail capabilities. This means that administrators can monitor and track who accessed a particular area and when, providing a valuable tool for security and accountability.

Cons of Biometric Access Control

• Initial Costs

Implementing biometric access control systems can come with a significant upfront cost. The technology itself, along with installation, training, and integration, can strain budgets, especially for small businesses or organizations.

• Privacy Concerns

Collecting and storing biometric data raises privacy concerns. Individuals may be hesitant to provide such sensitive information, fearing its misuse or potential data breaches.

• Technical Challenges

Biometric systems can face technical challenges. Factors like environmental conditions (lighting, cleanliness, etc.) can affect the accuracy of recognition. This may lead to instances of legitimate individuals being denied access or unauthorized access being granted.

• Scalability

With biometric systems, scalability can be a concern for larger organizations. Managing a database of biometric templates for a vast number of employees or users can become complex.

• False Rejections

Although biometric systems strive for accuracy, instances of false rejections can occur. Factors like changes in appearance (hairstyle, facial hair, etc.) can lead to the system failing to recognize authorized users.

• Lack of Universality

Not all biometric traits are universal. Some individuals might have physical conditions that prevent certain biometric methods from being effective, limiting the inclusivity of the system.

Biometric access control technology offers a compelling solution for enhancing security and convenience across various domains. Its robustness, accuracy, and non-transferable nature are appealing features, yet the associated costs, privacy concerns, and technical challenges cannot be overlooked. Businesses and organizations considering the adoption of biometric access control must carefully weigh these pros and cons to determine if the technology aligns with their security objectives and resources. As the technology continues to evolve, addressing these challenges could pave the way for an even more secure and efficient future.

Access control is necessary for protecting your business from unauthorized visitors. In addition to providing protection, access control systems bring a host of benefits to help you manage access to areas in your business. There are several main types of access control systems, and each works differently to authorize and control visitors’ and employees’ access to what they need.

Types of Access Control Systems for Your Needs

Access control systems must meet all security needs regarding allowing employees and visitors access to your commercial facility. Your ideal access control type is dependent on your property’s safety and security requirements, as well as the people you intend to involve in your business.

All access control systems create a record in the system’s database when someone uses an access card or other method to enter and exit the premises or access digital resources. The way the owner or system administrator assigns permissions and gives access to employees and other people differs depending on the system type.

Some access control systems are more restrictive while others are more lenient in granting permissions. Many systems are based on the principle of least privilege, which dictates that employees should have no more than the minimal permissions required to perform their job duties adequately.

These strict principles allow employees access to only the exact tools and resources they need for their position and nothing else. Consider the following options when installing an access control system for your business.

Discretionary access control

With a discretionary access control (DAC) system, the company owner determines who can access a particular location. This system also manages access to digital files and other resources. When an employee tries to enter through a particular access point, whether a digital or physical location, the DAC system checks against the list of people who have access and grants it by comparing it to the scanned fingerprint, card, or another form of identification.

DAC has its advantages of being flexible and easy to use, but it requires the owner to manage access actively. It also gives complete access to only one user over all other permissions, which owners can abuse when the permissions provide access to other programs.

Mandatory access control

Also called managed access control, mandatory access control (MAC) is a highly secure access control system standard in companies where confidentiality is necessary. Company owners do not control who has access to classified information or a restricted location, but they can access the MAC system. A system administrator sets all permissions for door entry, which prevents the wrong people from changing permissions and accessing information they don’t have the authority to see.

Mandatory access control is most popular with confidential military data due to its restrictive characteristics. The system sorts everyone who will use the program and either grants or denies access based on the criteria set by the system administrator. That said, the downside with this system is that the system administrator must permit the changes to the access control settings.

Role-based access control

A fast, new system for managing access control in a business is role-based access control (RBAC). Company owners create job titles within the system and assign specific permissions to each job, giving new access more quickly and easily, especially when employees change positions. Users must confirm their role in the system to gain access.

RBAC ensures that those who do not have the proper knowledge cannot perform tasks that require more experience than they have. When an employee gets a promotion, company owners can change their RBAC system role rather than wasting time assigning specific permissions to them. This is incredibly convenient due to the limited amount of time required to alter physical entry permissions or give access to programs for certain company positions.

Rule-based access control

Customization among access control systems is essential in providing the flexibility you need to protect your property, employees, and guests. Rule-based access control adds another layer of specificity to access control. System administrators set rules that determine when and how employees access locations and resources.

Combining rule-based and role-based access control is common to add further access restrictions that narrow permissions down to specific details. While role-based access control allows certain types of employees access on account of their job, rule-based access control can define other conditions such as hours of access.

Attribute-based access control

Another popular and easy-to-use system, attribute-based access control (ABAC) focuses on providing access based on user characteristics. Like rule-based access control, ABAC doesn’t involve employee roles and instead focuses on other factors, including location and group, to allow the system to grant access to employees.

Company owners can assign different types of attributes to employees, such as:

1. Resource attributes: File names, file owners, and other digital characteristics
2. Subject attributes: Department, group, security clearance level, and personal characteristics
3. Action attributes: Characteristics involving how someone wants to act in order to access a resource
4. Environmental attributes: External and contextual attributes such as visitor access time or company policies

Identity-based access control

Identity-based access control (IBAC) bases access control permission off of biometrics. Fingerprints and face structure are unique ways to give an individual access to areas within a business. Because face structure, fingerprints, and eye patterns are specific to each person, an IBAC system creates a simple way to control access without the chance of mistaken identity.

Smartphones, touchscreen systems, face scanners, touchpads, and more allow biometrics to form the basis for security at your business. Access control systems with video cameras and biometric detection give double assurance that customers will not have access to employee-only areas and that employees will have access solely to their assigned areas.

Access Control System Hardware

Here is a brief guide to various access control system parts.

Key cards and fobs

One of the things that buildings have to replace quite often is keys. However, when you have an access control system in place, key cards or access cards take the place of keys. Key cards will not only save you money on key replacement costs but are also easier to store.

Key cards allow you to access your building or certain rooms in a building by simply scanning or swiping them through a reader. Because each card is uniquely encoded, you can determine what door it can access. Essentially, this means that some areas of your building can remain inaccessible if need be.

Key cards are normally no larger than a normal bank card, which means they can easily fit inside a wallet. You can disable a key card at any time. In other words, if you lost your card or it got stolen, you won’t need to worry about any unwelcome visitors being able to access your facility.

You can also get fobs or key cards that grant access based on proximity. These work using radio-frequency identification (RFID), and you simply need to hold up the card or fob to the reader to gain entry.

Key card readers

One of the most important parts of a door access control system is the card reader. This electronic device scans the entry cards to grant your access to a building or room. While there are several types of card readers, they are all programmed to read the unique code of an entry card.

Decide which type of card reader will work best for your business before investing in an access control system. Card readers normally attach to the door itself or can be mounted to the wall next to the door they control.

The more restricted areas you have, the more card readers you will need. The great thing about them is that you don’t have to enter a password to enter. You can simply swipe, scan, or insert your key card to enter the room.

Keypads

If you prefer to not use entry cards to gain access to a building or restricted area, then keypads may be the perfect solution for you.

With a keypad, you don’t have to keep tabs on any access control parts. Instead of scanning an entry card, you can enter a passcode on a numeric keypad to enter a building or room.

However, it doesn’t have to be an either-or situation. You can use both card readers and keypads in your access control system.

Keypads act as an extra layer of security. You can use both a card reader and a keypad at the same door if need be.

Biometric readers

Keyless access systems

If you don’t want to carry around a key card or remember a pin code, then you could opt for a keyless system or smart lock. This can function using your smartphone. The reader uses Bluetooth to communicate with your phone and grant access via an app.

Keyless systems are convenient and secure as you need to have the right credentials on your phone in order to gain access.

Locking components

Every door needs a lock. With access control systems, this lock is electronic so that it functions alongside the card reader or keypad to lock or unlock the doors when access is granted to a building or a room.

There is more than one type of electronic hardware available, such as electromagnetic locks or electric strikes. The electric lock hardware you install will be dependent on the type of door.

Electric lock hardware allows you to freely exit the building whenever you need to. This means that in case of an emergency, you can unlock all doors instantaneously, ensuring that everyone will be able to get to safety and not be hindered by your access control system hardware.

Field control panels

Field control panels are the parts of door access control systems that help connect all elements together via a control panel. These panels are responsible for processing and relaying access control activity throughout the entire building to the access control software.

If you have a relatively large building with lots of access control activity, then you will need more panels. If you have a smaller location, then you may need to install only a couple of panels.

These panels are typically installed via electrical, communication, or telephone closets.

Alarms

To ensure the safety of staff or customers, access control systems often connect to fire or intrusion alarms. This helps your entire business security system to work in unison should an emergency occur.

If a fire breaks out or an unauthorized person attempts to access doors that are controlled by electric lock hardware, your access control system can sound an alarm.
