At their core, access control systems are security solutions designed to restrict or grant access to physical or digital environments based on predefined rules. These systems determine who can access a certain location, when they can access it, and under what conditions.

While traditionally associated with physical spaces like offices and server rooms, today’s systems extend their functionality to include data centers, multi-tenant properties, co-working hubs, and even cloud applications.

Legacy access control systems were often tied to on-premise servers and required significant hardware investment. Today’s smarter alternatives like MR.TECH’s cloud-based access control systems are revolutionizing the landscape.

These systems eliminate the need for local servers, reduce IT costs, and provide seamless updates. They are also mobile-first, allowing users to unlock doors using their smartphones, a feature highly appreciated in co-working spaces, modern offices, and apartment complexes.

Different environments require different access models. Common types include:

1. Discretionary Access Control (DAC)

The owner decides who has access to what. It’s flexible but can lead to inconsistent policies.

2. Mandatory Access Control (MAC)

Permissions are strictly enforced by a central authority. Common in government and military applications.

3. Role-Based Access Control (RBAC)

Access is granted based on roles within the organization — ideal for businesses of all sizes.

4. Attribute-Based Access Control (ABAC)

Grants access based on user attributes (e.g., department, time of day, location).

5. Break-glass access control

Break-glass access control involves the creation of an emergency account that bypasses regular permissions. In the event of a critical emergency, the user is given immediate access to a system or account they would not usually be authorized to use.

6. Rule-based access control

A rule-based approach sees a system admin define rules that govern access to corporate resources. These rules are typically built around conditions, such as the location or time of day that users access resources.

Imagine managing access for a commercial building housing multiple businesses, each with different schedules, employee roles, and visitor policies. Traditional systems would require individual control panels and physical oversight.

A cloud-based, mobile-enabled system, however, allows centralized management with customizable policies per tenant. Real-time monitoring ensures visibility across all entrances, while the system integrates smoothly with elevators, parking garages, and emergency exits.

Providers like Spintly specialize in solving such multi-layered access scenarios, delivering both flexibility and control.

Access control is used to verify the identity of users attempting to log in to digital resources. But it is also used to grant access to physical buildings and physical devices.

Access control is a data security process that enables organizations to manage who is authorized to access corporate data and resources.

The different types of access control include:

• Attribute-based Access Control (ABAC)
• Discretionary Access Control (DAC)
• Mandatory Access Control (MAC)
• Role-Based Access Control (RBAC)
• Break-glass Access Control
• Rule-based Access Control

• User presents credential (mobile app, card, or biometric)
• Reader scans the credentials and sends data to the controller
• Controller verifies access rights
• Access is granted or denied based on the policy
• System logs the attempt for auditing purposes
• This entire process takes less than a second and can be configured to notify security teams, track anomalies, or even trigger other systems like CCTV or alarms.
