Data Privacy and Compliance in Physical Access Control Systems

Written by Jay Palter | Feb 13, 2025

It is becoming increasingly difficult to tell where physical business systems end and digital ones begin. This is nothing new. In fact, we’ve previously discussed the merging, or convergence, of physical and network security. What is new are the second—and third-wave challenges organizations face from convergence.

A case in point is the impact of new data privacy regulations on the use of Physical Access Control Systems (PACS).

Modern access control systems can collect, store, and analyze sensitive personal data, such as biometric data or access logs. While PACS enhance security and operational efficiency, their use also introduces new risks related to data privacy regulations. 

This article explores the critical relationship between physical access control and data protection. We’ll examine the complex challenge of regulatory compliance and best practices to ensure that your access control measures don’t compromise user privacy.

 

How Access Control Systems Collect and Store Sensitive Data 

The heart of the issue is that PACS no longer operate in isolation. They connect with broader security systems and frameworks, such as identity management platforms, visitor tracking requirements, and emergency response protocols. As access control technologies continue to evolve, organizations must consider not only security but also the privacy and ethical implications of collecting and storing such highly detailed personal data. 

Let’s break down the components of a PACS, which will make it clear just how many interactions you can have with these systems that generate user data. 

Key Components of a Physical Access Control System (PACS)  

Component  Description 
Access point  This is the physical barrier where people interact with PACS, such as turnstiles, security gates, and electronically controlled doors. 
Credential reader 

To authorize their access, individuals must present credentials, such as swipe cards, RFID fobs, PIN codes, or biometrics. 

 When using biometric data, such as fingerprints, facial recognition, or iris scans, the PACS will match the individual's scan against stored records. 

Control panel  The control panel processes credential data from the reader verifies it against the credential holder database, and determines access authorization. In many settings, a modern PACS allows you to interact in other ways. For example, you could log the reason for visiting a high-security access point. 
Access control server  A networked computer system stores credential data, access logs, and additional data collected at the access point. Server software also allows administrators to manage registrations, credential enrollment, validation, and system event logging, all of which generate their own data. Smart technologies, such as intelligent lockers and key management systems, complement broader cybersecurity measures by securing access to sensitive equipment and data-carrying devices.

 

How PACS Components Work Together to Secure Facilities

While specific PACS vary in design and capabilities, they generally manage five access control activities: 

 

Regulatory Compliance for Physical Access Control Systems 

That’s the data collected and processed by standard PACS. On the surface, it's clear that much of this data is sensitive and needs some level of protection. However, many jurisdictions have mandated data privacy in recent years and instituted strict controls and penalties for it.

 

Key Data Privacy Regulations Impacting Access Control 

General Data Protection Regulation (GDPR) - European Union

GDPR is the most comprehensive data privacy law and the one that had the furthest-reaching global impact upon its release. It applies to any company handling the personal data of EU residents, regardless of location or nationality. It mandates strict data collection, storage, and security standards and provides rights for individuals to access, change, and erase their personal data.   

Health Insurance Portability and Accountability Act (HIPAA) - United States

HIPAA governs the handling of medical and health-related data, ensuring patient information is securely stored, processed, and shared only with authorized parties.   

Personal Information Protection and Electronic Documents Act (PIPEDA) - Canada

Canada’s federal privacy law regulates the collection and use of personal data in commercial activities. It emphasizes data transparency and user consent.   

California Consumer Privacy Act (CCPA) - United States

The CCPA grants California residents control over their personal information, allowing them to access, delete, and limit business data sharing. It has set a precedent for similar state-level privacy laws across the U.S., many of which will be coming soon.

Personal Information Protection Law (PIPL) - China

PIPL imposes strict rules on data processing, requiring companies to obtain user consent, limit data collection, and meet stringent cross-border data transfer regulations.

Protection of Personal Information Act (POPI) - South Africa

POPI establishes data protection standards for organizations operating in South Africa.

Lei Geral de Proteção de Dados (LGPD) - Brazil

LGPD mirrors GDPR principles, requiring companies to safeguard personal data and adhere to similar accountability and transparency requirements.

 

Cybersecurity Standards for Secure Access Control Management  

Network and Information Systems Directive (NIS2) - European Union

NIS2 strengthens cybersecurity requirements for organizations providing essential network infrastructure services in the EU. It includes perimeter security, building access, visitor management, and incident response provisions.   

European Union Artificial Intelligence Act (EU AI Act)

This legislation sets guidelines for the ethical and transparent development and use of AI systems, classifying risks and enforcing compliance measures with significant penalties for violations. If an AI has access to personal access control data, even if it’s not actively using it, it would fall under the jurisdiction of the EU AI Act.

ISO 27001 - International

The other regulations listed here are all governmental. ISO is a private industry-based standard that outlines best practices for information security management. While certification is not mandatory, many companies adopt ISO 27001 to demonstrate their commitment to data protection and risk management, including handling personally identifiable data.

 

Integrating Physical Security and Data Privacy 

Physical security and data privacy are deeply interconnected. A breach in one domain can easily compromise the other. For example, unauthorized access to a restricted physical space, like an executive’s office, can lead to stolen sensitive data. On the flip side, a cyberattack might manipulate access control systems to allow intruders into secured locations. 

Access control systems are reliable safeguards against unauthorized access to both physical and digital assets. However, this is only possible if you implement strict access control policies for using your systems, especially within an integrated security environment. By doing so, organizations can enhance security, comply with data protection regulations, and reduce breach risks without sacrificing one for the sake of another.

 



Best Practices for Access Control Data Protection 

Consider adopting one or more of these practices to effectively manage access control and data privacy.

 

1Integrated Security for Physical and Digital Protection

A strong security framework combines physical and digital security measures into a unified system—in other words, security convergence. By integrating surveillance cameras, access control systems, and cybersecurity protocols, you will have a more complete view of organizational activity with fewer gaps left for threats to exploit. 

2Implementing Multi-Factor Authentication (MFA) in PACS  
 

Enhances security by requiring multiple forms of use authentication at access control points. You’ll not only secure physical entry points themselves, but also ensure that only authorized personnel can access sensitive data. 

3Role-Based Access Control (RBAC) for Enhanced Security  

Limits access based on job responsibilities, ensuring that individuals can only access data necessary for their roles—meaning their jobs and other individual responsibilities within your organization. 

4Least Privilege Principle for PACS Security

It grants users the minimum access necessary to perform their roles effectively. Just because an executive wants to be able to check on everything doesn't mean their credentials need access to everything. By restricting access to only what is essential, you‘ll reduce the number of potential vulnerabilities. 

5 Real-Time Monitoring and Incident Response for PACS 

Utilize advanced surveillance and monitoring tools to detect and respond to suspicious activities immediately. 

6 Data Encryption Strategies for Secure Access Logs 

Encrypts data at entry points, such as badge scans and biometric data, to ensure that data intercepted between the control panel and PACS server remains protected. 

7 Developing an Incident Response Plan for Access Control Breaches 

Develop and maintain a comprehensive plan for responding to security breaches. This plan should outline the steps to be taken in the event of a breach, including fully identifying it, containing the damage, eliminating the threat, and recovering affected systems. 

8 Regular Audits and Compliance Reviews for PACS Security 

Conduct regular audits of your systems and policies. This will help you identify and rectify new vulnerabilities within each that have emerged due to changes to your organization or the threat landscape. 

9 Employee Training and Awareness for Data Privacy 

Regular training sessions educate employees on the importance of data privacy and access control security. They also inform them about changes in process and pol and any new threats they’re likely to encounter. 

10Scalability and Adaptability in Access Control Systems 

Ensures security systems can grow with the organization's operations and adjust to evolving security demands. 

  

Choosing the Right Access Control Vendor to Support Regulatory Compliance 

Keeping up with evolving data protection and privacy standards requires the right technology and trusted vendor partnerships. A reliable vendor should demonstrate a strong commitment to compliance, providing the necessary resources, legal expertise, and certified solutions to help organizations navigate regulatory changes. Look for vendors with recognized certifications from governing bodies, ensuring their products and business operations align with industry standards.
