Understand Policy-Based Access Control (PBAC) for Businesses

In policy-based access control (PBAC), the system does more than attempt to match IDs to authorization lists. PBAC systems evaluate specific policies or conditions to produce more dynamic and context-aware access decisions.

Abdalslam notes that 75% of businesses rank physical security among their primary concerns. This statistic emphasizes the significance of protecting tangible assets and areas, further accentuating the importance of PBAC.

Let's dive deep into understanding PBAC and why it's becoming a game-changer for organizations.

Policy-Based Access Control (PBAC)

PBAC stands for Policy-Based Access Control. It’s the most efficient and effective method for managing site authorizations.

Unlike other access control decision-making protocols, which often focus on a credential holder’s ID as a basis for access decisions, PBAC makes access decisions based on policies or conditions that must be met.

It's like setting up a rulebook for your security system.

Access is granted if the conditions (including ID) are right; if not, it's denied.

Key Components of PBAC

The primary factors considered by PBAC systems are access authorization policies, attributes related to users, attributes related to resources, and preprogrammed rules applied when making access decisions.

Access Authorization Policies

Authorization policies form the core of any PBAC system. These policies define specific conditions or rules that must be satisfied for access to be granted.

For example, an access rule might state that only employees of a particular department can access certain files or that access to a specific server is restricted after business hours.

By clearly specifying these rules, organizations can ensure a high level of security, making sure resources are accessed only under predefined conditions.

User Attributes

User attributes refer to specific characteristics or properties associated with individual users. User attributes may include the role in the organization (e.g., manager, technician, intern), their location, and the credential types they use.

PBAC systems assess these attributes to evaluate whether a user meets the criteria set out in the access authorization rules.

For example, if a rule allows only managers to access financial data, the system will check the user's role before granting access.

Resource Attributes

Resource attributes pertain to the properties of the resources being accessed. Resource attributes can range from specific doors in a building to databases, files, or even network segments.

Attributes may include the sensitivity level of a file, the location of a physical resource, or the type and value of assets in a storage area.

By evaluating attributes, the PBAC system can determine if the user's request to access a particular resource aligns with established access authorization rules.

Preprogrammed Rules

Preprogrammed rules are built into the PBAC system to handle particular scenarios and to make access decisions based on real-time data.

For example, a preprogrammed rule might automatically deny all external access attempts during non-business hours or immediately lock down certain areas if a security breach is detected.

These rules allow the system to act swiftly and autonomously, ensuring security even in dynamic and potentially volatile situations.

Benefits of PBAC

• Dynamic and Flexible: PBAC systems adapt to changing conditions. For instance, if a policy restricts access during weekends, an employee trying to enter on a Saturday would be denied access to the same spaces they can access during weekdays.
• Context Sensitive: PBAC enables real-time authorization decisions based on contextual information. By considering factors such as user attributes, resource characteristics, and environmental variables, PBAC makes access decisions in a highly granular and context-aware manner.
• Shared Reasoning: PBAC systems explain the reasoning behind access decisions. Organizations use this information to understand why particular access requests are approved or denied. This feature aids in auditing, compliance, and governance efforts.
• Scalability: As your organization grows, so do your security needs. PBAC systems can easily accommodate new policies without requiring a major overhaul.
• Enhanced Security: By creating stringent policies, you can ensure that only the right individuals have access under the right conditions.

PBAC vs. RBAC

Role-Based Access Control (RBAC) has long been a staple in the domain of advanced entry management. In RBAC systems, access permissions are based on the roles of individual users within an organization.

These roles determine what data or system areas a user can access and what operations they can perform. For example, an HR manager might have different access permissions than a sales executive.

While RBAC provides a straightforward and organized way to manage access, it lacks the flexibility required in many of today's most dynamic and complex environments.

Enter Policy-Based Access Control (PBAC). Unlike RBAC, PBAC empowers organizations with granular and context-aware access control that seamlessly adapts to evolving needs and dynamic security protocols.

Implementing PBAC With Top Brands

Several leading brands offer advanced PBAC solutions:

• Avigilon: Avigilon, known for state-of-the-art camera systems and advanced artificial intelligence (AI), offers robust access control policy solutions, including policy-based access control.
• ICT: ICT access control systems are designed for scalability, making them perfect for PBAC integration.

Best Practices for PBAC Implementation

• Clear Policy Definition: Plan and configure your access control system for PBAC. Make sure your policies are clearly defined, and test the system under varying conditions to make sure it functions optimally.
• Regular Audits: Periodically review and update your policies to address any changes or potential vulnerabilities.
• Integration with Other Systems: For enhanced security and situational awareness, integrate PBAC systems with other security systems, such as systems for video surveillance, intrusion detection, and fire safety.
• Training: Ensure that your staff understands the PBAC system, its benefits, and its operation. The rules your PBAC system applies should be defined and understood by administrators, end-users, and other stakeholders.
