For the last decade, “Zero Trust” has been the dominant framework in cybersecurity. The concept, popularized by Forrester and adopted by NIST, is simple in theory but rigorous in practice: Never trust, always verify.
In the IT world, this means assuming the network is already compromised. Organizations no longer rely solely on perimeter firewalls; instead, they verify identity and strictly limit privileges for every user and device, everywhere.
At Systems Integrations, serving businesses across Southern New Jersey, Southeastern Pennsylvania, and Delaware, we are witnessing a fundamental paradigm shift: Physical security is now an IT asset. The days of “security through obscurity” or relying solely on locked doors are over. To protect modern facilities in Camden County, Gloucester County, and the greater Philadelphia region against sophisticated threats, businesses must apply Zero Trust Architecture (ZTA) principles to physical access control systems.
Here is how advanced IT security concepts translate to the physical realm—and why your South Jersey business needs this approach today.
Zero Trust Authentication: MFA for NJ Physical Security Systems
In traditional access control systems, possession of a credential (a proximity card) equaled trust. If you held the card, the system trusted you. This is the equivalent of a static password—and just as vulnerable.
In a Zero Trust Physical Security environment, possession is not enough. Businesses must move toward Multi-Factor Authentication (MFA) at the door.
The IT Concept: MFA (Password + Token)
The Physical Application: Card + PIN or Mobile Credential + Biometric (Face/Fingerprint)
The Critical Upgrade: Moving away from insecure 125kHz Proximity cards—which can be cloned in seconds—to encrypted credentials (DESFire EV3) or mobile credentials that utilize the phone’s inherent biometric security.
Why This Matters in South Jersey: Manufacturing facilities in Gloucester County’s Pureland Industrial Complex and wealth management firms in the Philadelphia suburbs handle sensitive assets and data. A cloned proximity card in the wrong hands can compromise your entire facility. Our SIA-certified cybersecurity engineers ensure your credentials meet modern security standards.
2. Micro-Segmentation: Zoning Your Facility Like a Network
IT networks use micro-segmentation to prevent lateral movement. If a hacker breaches the guest Wi-Fi, they should not be able to access the HR database.
Physical security often fails here. Once an employee badges into the “Employee Entrance,” they frequently have unrestricted access throughout the building.
The IT Concept: VLANs and subnet isolation
The Physical Application: Treating your building as distinct security zones. The lobby is the “DMZ.” The server room or R&D lab is the “Core.”
Implementation Strategy: Employees should not have “All Access” by default. A marketing employee’s credential should not trigger the reader in the server room—not even to log an “Access Denied” event. That door should be invisible to their credential.
Local Application: A Camden County CPA firm should not allow front-office staff credentials to access the secure document storage area. A Delaware manufacturing facility should segment production floor access from administrative areas. This is security architecture, not just access control.
3. Least Privilege Access: Dynamic Provisioning and Integration
The Principle of Least Privilege (PoLP) states that users should be given only those privileges needed to complete their tasks—nothing more.
The IT Concept: Just-In-Time (JIT) access management
The Physical Application: Why does a 9-to-5 contractor have 24/7 access privileges? Why does a terminated employee’s badge still work three days later?
The Critical Strategy: Integration with Active Directory (AD) or HR software is essential. When an employee is terminated in your HR system, their physical access should be revoked instantly—not when the facilities manager reads the email. Access schedules must be granular. If a shift ends at 5:00 PM, access should automatically expire at 5:30 PM.
Why This Protects South Jersey Businesses: Property management companies in Southern New Jersey managing multiple buildings need centralized, automated access control. When a tenant moves out or a maintenance contractor’s project ends, their access should terminate automatically. This prevents unauthorized after-hours access and reduces liability exposure.
4. Device Hardening and Encryption: OSDP vs. Wiegand
This is the most technical—and most critical—vulnerability in legacy systems. For decades, access control readers communicated with controllers using the Wiegand protocol, an unencrypted, plain-text communication standard.
If you are running Wiegand, you are vulnerable to “Man-in-the-Middle” attacks where a device placed behind a reader can capture card data in plain text and clone credentials.
The IT Concept: TLS/SSL Encryption for data in transit
The Physical Application: OSDP (Open Supervised Device Protocol) with Secure Channel
The Requirement: To achieve Zero Trust, communication from the reader to the controller, and the controller to the server, must be encrypted (AES-128 or higher). OSDP Secure Channel ensures that even if the wiring is physically tapped, the data remains unreadable.
Why Systems Integrations Emphasizes This: As the only SIA Cybersecurity-Certified security integrator in the region, we understand that your access control system is a network endpoint. Our installations in Pennsylvania, New Jersey, and Delaware use OSDP-compliant hardware and encrypted communication protocols to prevent credential theft and system compromise.
5. Continuous Monitoring and Anomaly Detection
Zero Trust requires assuming a breach is happening right now. You cannot rely on forensic review after a theft occurs.
The IT Concept: SIEM (Security Information and Event Management) and UEBA (User and Entity Behavior Analytics)
The Physical Application: Intelligent integration of access control and video surveillance systems
Implementation Examples:
- “Impossible Travel”: If Employee A badges in at the front door, and two minutes later badges in at a rear warehouse door that takes ten minutes to walk to, the system flags this as a cloned card or credential sharing.
- “Tailgating Detection”: Using AI-enabled cameras to count people entering versus the number of badge scans, identifying unauthorized entry.
- “After-Hours Anomalies”: Alerting when a credential that typically accesses the building Monday-Friday 8 AM-5 PM suddenly appears at 2 AM on a Saturday.
Regional Application: A South Jersey logistics center can detect when a driver credential is used to access restricted inventory areas. A Philadelphia-area medical office can identify when a credential accesses the medication storage room outside normal clinic hours. These real-time alerts prevent theft, diversion, and compliance violations.
The Bottom Line: Your Physical Security System is a Computer Network
Merging cybersecurity principles with physical security is not just about buying new cameras or card readers—it is about adopting a philosophy of verification over trust.
Your physical security system is a computer network. It has IP addresses, firmware, user databases, and network connectivity. If you are not securing it with the same rigor as your corporate data center, you are leaving the door wide open—literally.
Critical Questions for South Jersey Business Owners:
- Are your access control readers using encrypted communication protocols?
- Can a terminated employee still badge into your facility?
- Does your contractor have the same access privileges as your CEO?
- Can you detect when a credential is being shared or cloned?
- Is your access control system segmented from your business network?
If you answered “no” or “I don’t know” to any of these questions, your facility is operating on trust, not verification.
