Access control systems: A complete business guide

A visitor management systems (VMS)plays a crucial role in ensuring the safety and security of any organization by streamlining the check-in and monitoring process for visitors. By digitally registering visitors, companies can enhance security, track arrivals, and ensure compliance with internal policies. On the other hand, Access Control Systems provide an added layer of security by managing who can enter specific areas within a facility. When integrated with a visitor management system, access control solutions help ensure that only authorized visitors are granted entry, further strengthening an organization's security framework. Together, these systems offer a comprehensive approach to building a safe and efficient environment.

What is an access control system?

Access control system refers to the practice of restricting and managing entry to certain areas, information, or resources. It involves systems and protocols that verify an individual’s identity before granting or denying access. These  solutions are crucial for safeguarding physical and digital assets, ensuring a secure and efficient environment.

Types of access control systems

There are several types of access control systems, each catering to specific needs. Let’s explore the primary categories:

1. Discretionary access control (DAC)

Discretionary access control (DAC) allows the resource owner to determine who is granted access.  This type offers flexibility but requires careful management to prevent unauthorized entry.

2. Role-based access control (RBAC)

Role-based access control (RBAC) assigns access permissions according to predefined roles within an organization. For instance, employees in the IT department may have access to server rooms, while marketing teams do not.

3. Mandatory access control (MAC)

MAC is a highly secure method where access is determined by strict policies set by administrators. This is commonly used in government and military facilities.

4. Biometric access control (BAC)

This type leverages unique biological traits such as fingerprints, facial recognition, or iris scans to verify identity. This method enhances protection and substantially lowers the chances of unauthorized entry.

Importance of access control systems

Access control systems  are more than just security tools; they are integral to efficient operations and risk management. Here are key reasons why they matter:

• Enhanced Security: Restrict entry to critical areas to safeguard assets and minimize risks like theft or data compromise.  
• Operational Efficiency: Streamline employee movement, ensuring smooth access without manual checks.
• Compliance: Meet industry regulations by maintaining logs of who accessed restricted areas and when.
• Scalability: Adapt to the changing needs of a growing business, accommodating new users and areas easily.

What is an access control policy?

An access control policy is a set of guidelines that dictate how access is granted within an organization. It establishes uniformity and responsibility by outlining clearly:

• Who: Specifies which individuals or roles are allowed entry.
• What: Details the resources and areas covered by the policy.
• When: Sets access schedules, restricting entry outside permitted hours.
• How: Outlines the authentication methods used, such as passwords, cards, or biometrics.

Developing a robust access control policy minimizes risks and aligns security practices with organizational goals.

Key components of access control systems

An  access control system  is made up of essential elements that collaborate to maintain security and operational efficiency:

How access control systems works

Access control systems operate through a defined sequence of steps to maintain both security and smooth functionality: 

1. Authentication: When an individual attempts to access a restricted area, the system verifies their credentials using devices like keycards, PINs, or biometrics.
2. Authorization: The access control panel checks the credentials against its database to determine if access should be granted or denied.
3. Access Logging: The system records every access attempt, including time, location, and user identity, for future reference or compliance needs.
4. Action: Based on the decision, the system either unlocks the entry point or denies access, often triggering alerts for unauthorized attempts.

These systems integrate seamlessly with other workplace technologies, creating a robust and dynamic security environment.
