Securing Wireless CCTV Networks: A Deep Dive into WPA3-Enterprise and VLAN Segmentation

As a UK-certified installer with years of hands-on experience in network infrastructure and security, I’ve witnessed the rapid evolution of surveillance technology. Wireless CCTV systems, once a niche, are now ubiquitous, offering unparalleled flexibility in deployment. However, this convenience often comes at a significant security cost if not properly addressed. A poorly secured wireless CCTV network isn’t just a potential privacy breach; it’s a gaping vulnerability in an organisation’s broader network perimeter.

This article delves into two fundamental, yet often underutilised, pillars of robust wireless network security: WPA3-Enterprise and VLAN Segmentation. Together, these technologies offer a formidable defence, transforming an inherently exposed wireless vector into a resilient and isolated security asset. My aim here is to provide an engineering-grade overview, complete with practical considerations, for IT professionals and security integrators looking to elevate their wireless CCTV deployments beyond rudimentary, insecure setups.

The Imperative for Advanced CCTV Security

Traditional CCTV deployments relied heavily on wired infrastructure, benefiting from the inherent physical security and isolation. The advent of wireless technology, while offering immense practical advantages, introduces a new attack surface. Unsecured or weakly secured wireless links are susceptible to:

• Eavesdropping: Unauthorised access to video feeds and camera management interfaces.
• Tampering: Alteration of footage or camera settings, potentially disabling surveillance.
• Denial-of-Service (DoS): Disrupting camera communication, rendering the system inoperable.
• Network Penetration: Using a compromised camera as a pivot point to access other critical network resources.

The widespread adoption of WPA2-Personal (PSK) with a shared passphrase, or even worse, open Wi-Fi, for wireless CCTV is a critical misstep. A single compromised passphrase or brute-force attack can expose the entire surveillance network. This is where the advanced capabilities of WPA3-Enterprise, coupled with intelligent network segmentation via VLANs, become indispensable.

The Evolution of Wireless Security: From WPA2 to WPA3-Enterprise

Before we dive into WPA3-Enterprise, it’s beneficial to briefly recap its predecessor and understand why the evolution was necessary.

WPA2-Enterprise: Strengths and Limitations

WPA2-Enterprise, based on the IEEE 802.1X standard, offered a significant leap over WPA2-Personal by introducing centralised authentication. Instead of a shared passphrase, each client authenticates individually using credentials (username/password or certificates) against a Remote Authentication Dial-In User Service (RADIUS) server.

Key Strengths:

• Individual Authentication: Each device has unique credentials, enhancing accountability and revocation.
• Centralised Management: RADIUS servers simplify user/device management across large networks.
• Robust Encryption: Utilises AES-CCMP for data encryption.

Limitations:

• KRACK Vulnerability: The Key Reinstallation Attack (KRACK) demonstrated a flaw in the 4-way handshake, allowing an attacker to replay, decrypt, and forge packets. While patches were issued, it highlighted a fundamental design weakness.
• No Management Frame Protection: Control and management frames (e.g., deauthentication, disassociation) could be spoofed, leading to DoS attacks.
• Limited Forward Secrecy: An attacker who compromises the long-term key might be able to decrypt past traffic.

WPA3-Enterprise: A Paradigm Shift in Wireless Security

WPA3, ratified by the Wi-Fi Alliance, addresses the shortcomings of WPA2 and introduces several critical enhancements, making it the de facto standard for secure wireless communication, especially for sensitive applications like CCTV.

Core Enhancements of WPA3-Enterprise:

1. Simultaneous Authentication of Equals (SAE): This is the game-changer for WPA3-Personal, replacing the WPA2-Personal 4-way handshake. While WPA3-Enterprise primarily relies on 802.1X/EAP, SAE provides enhanced resistance to offline dictionary attacks even in a Personal context, offering better protection where pre-shared keys are still used for less critical applications. The core benefit relevant to Enterprise is the enhanced key exchange mechanisms for forward secrecy.
2. Robust Management Frame Protection (MFP): Also known as 802.11w, MFP is a mandatory feature in WPA3. It encrypts and verifies management frames, preventing attackers from spoofing deauthentication or disassociation requests, thereby mitigating common DoS attacks that can disable cameras or disrupt network connectivity.
3. 192-bit Cryptographic Suite (CNSA-Compliant Mode): For high-security environments, WPA3-Enterprise offers an optional “Suite B” mode that enforces a 192-bit cryptographic strength, aligning with the Commercial National Security Algorithm (CNSA) Suite. This includes:
   • AES-256 in GCMP mode for data protection.
   • SHA-384 for hash functions.
   • Elliptic Curve Cryptography (ECC) with 384-bit curves. This level of encryption is significantly more resilient to future computational advances.
4. Enhanced Forward Secrecy: WPA3’s improved key exchange protocols ensure that even if a session key is compromised, previous session traffic cannot be decrypted. This is crucial for protecting historical CCTV footage metadata or configuration changes.

Why WPA3-Enterprise for CCTV?

• Eliminates Shared Secrets: Each camera authenticates individually, meaning no single compromised passphrase exposes the entire fleet.
• Mitigates Offline Dictionary Attacks: Stronger key derivation reduces the risk of credential compromise.
• Resilience Against DoS: MFP prevents malicious actors from easily knocking cameras offline.
• Enhanced Data Confidentiality: The 192-bit suite offers government-grade protection where required.
• Simplified Credential Management: Integration with existing RADIUS servers (e.g., Microsoft NPS, FreeRADIUS) allows for centralised management of camera identities and access policies.

Technical Comparison: WPA2-Enterprise vs. WPA3-Enterprise

Feature	WPA2-Enterprise (802.1X/EAP)	WPA3-Enterprise (802.1X/EAP)	Significance for CCTV
Authentication	802.1X/EAP with RADIUS	802.1X/EAP with RADIUS	Centralised, individual device authentication.
Key Exchange	4-way handshake (susceptible to KRACK)	Enhanced 4-way handshake, SAE principles	Stronger key derivation, better forward secrecy.
Crypto Suite	AES-CCMP (128-bit)	AES-CCMP (128-bit) or AES-GCMP (192-bit)	Optional higher encryption for sensitive deployments.
MFP (802.11w)	Optional, often disabled	Mandatory	Prevents deauthentication/disassociation attacks, improved reliability.
Forward Secrecy	Limited	Improved (PFS - Perfect Forward Secrecy)	Past traffic remains confidential even if future keys are compromised.
Dictionary Attacks	Vulnerable to offline dictionary attacks (PSK)	More resilient to offline dictionary attacks (PSK)	Less relevant for Enterprise, but underlying principles enhance general key robustness.
Complexity	Moderate	Moderate to High (due to certificate management)	Requires careful planning and implementation expertise.

Implementing WPA3-Enterprise necessitates a functioning Public Key Infrastructure (PKI) for certificate-based authentication (EAP-TLS is recommended over username/password EAP methods like PEAP/TTLS for devices) and a robust RADIUS server. This investment in infrastructure pays dividends in long-term security and manageability.

VLAN Segmentation: The Cornerstone of Network Isolation

While WPA3-Enterprise secures the wireless link itself, VLAN segmentation secures the network context within which the CCTV operates. It’s a critical second layer of defence, ensuring that even if a device is compromised, the blast radius is confined.

What is a VLAN?

A Virtual Local Area Network (VLAN) is a logical grouping of network devices that behave as if they are on the same physical wire, regardless of their actual physical location on the network. This is achieved by tagging Ethernet frames with a VLAN ID (as per IEEE 802.1Q).

Why VLANs for CCTV Networks?

VLANs are not merely an organisational tool; they are a fundamental security control, particularly for wireless CCTV.

1. Enhanced Security through Isolation:
   • Containment: The primary benefit. If a wireless camera or NVR (Network Video Recorder) is compromised, the attacker gains access only to the devices within that specific VLAN, preventing lateral movement to critical corporate or operational technology (OT) networks.
   • Reduced Attack Surface: By isolating CCTV devices, you limit what they can see and communicate with on the network, reducing potential avenues for exploitation.
2. Improved Performance and Efficiency:
   • Smaller Broadcast Domains: Each VLAN forms its own broadcast domain. This reduces unnecessary broadcast traffic across the entire network, improving overall performance, especially in large environments.
   • Dedicated Bandwidth (Indirectly): While not direct bandwidth allocation, segmenting traffic types helps prevent one type of traffic (e.g., CCTV streams) from overwhelming another (e.g., VoIP or data transfer) within their respective segments.
3. Simplified Management and Troubleshooting:
   • Logical Grouping: Organise devices with similar security requirements or functions.
   • Easier Policy Enforcement: Apply specific Quality of Service (QoS) rules or Access Control Lists (ACLs) to an entire VLAN, streamlining network policy management.
4. Compliance: Many regulatory standards (e.g., GDPR for privacy, industry-specific compliance) require strict separation of systems handling sensitive data or critical operations. VLANs are instrumental in achieving this.

How VLANs Work: A Technical Primer

• 802.1Q Tagging: Ethernet frames are encapsulated with a 4-byte VLAN tag. This tag includes a 12-bit VLAN ID (allowing for 4094 unique VLANs) and other priority fields.
• Access Ports: A switch port configured as an “access port” belongs to a single VLAN. Traffic entering or leaving this port is untagged (or tagged internally by the switch before forwarding, and untagged on egress to the device). Devices connected to an access port are unaware of VLANs.
• Trunk Ports: A switch port configured as a “trunk port” carries traffic for multiple VLANs. Frames traversing a trunk port are tagged with their respective VLAN IDs. Trunk ports connect switches to other switches, or switches to Access Points (APs) that support multiple SSIDs mapped to different VLANs.
• VLAN Interfaces (SVIs) / Router-on-a-Stick: For communication between VLANs (inter-VLAN routing), a Layer 3 device (like a router or a Layer 3 switch) is required. On a Layer 3 switch, this is typically done via Switched Virtual Interfaces (SVIs), which are logical interfaces configured with an IP address for each VLAN. A traditional router uses sub-interfaces on a physical port to achieve “router-on-a-stick” functionality.
• Access Control Lists (ACLs): Once inter-VLAN routing is enabled, ACLs are crucial. They define granular rules for which VLANs can communicate, what protocols they can use, and to which specific IP addresses. For CCTV, an ACL might permit cameras in the CCTV VLAN to send video streams to the NVR in the management VLAN, but block all other traffic.

Designing a Robust CCTV VLAN Architecture

A typical secure wireless CCTV deployment might involve several VLANs:

1. CCTV Devices VLAN (e.g., VLAN ID 100):
   • Purpose: Dedicated to wireless IP cameras.
   • Characteristics: Devices here should have no direct internet access unless explicitly required for cloud services (and even then, strictly controlled). Limited egress rules to the NVR and potentially a time server. No ingress rules other than from the NVR or management station.
   • IP Addressing: A dedicated IP subnet (e.g., 192.168.100.0/24).
2. Management VLAN (e.g., VLAN ID 99):
   • Purpose: For NVRs, network switches, wireless access points, and potentially a dedicated management workstation.
   • Characteristics: Highly restricted access. Devices here manage the network and CCTV system. Access should be limited to specific management protocols (SSH, HTTPS, SNMP).
   • IP Addressing: A separate IP subnet (e.g., 192.168.99.0/24).
3. Corporate/User VLAN (e.g., VLAN ID 10):
   • Purpose: Standard user workstations, servers, etc.
   • Characteristics: Should have no direct access to the CCTV VLAN. Access to NVR might be allowed via specific firewall rules, perhaps through a proxy or a dedicated viewing station in the management VLAN.
4. Guest VLAN (e.g., VLAN ID 20):
   • Purpose: For guest Wi-Fi access.
   • Characteristics: Completely isolated from all other internal VLANs, with internet-only access.

Step-by-Step Guide: Implementing VLANs for Wireless CCTV

This is a high-level guide; specific commands will vary based on hardware vendors (Cisco, Ubiquiti, HP, etc.).

1. Network Design and Planning:

• IP Addressing: Define subnets for each VLAN (e.g., VLAN 100: 192.168.100.0/24; VLAN 99: 192.168.99.0/24).
• VLAN IDs: Assign unique IDs (e.g., 100 for CCTV, 99 for Management).
• AP Placement: Conduct a thorough wireless site survey to ensure adequate coverage and minimise interference.
• Device Inventory: List all wireless CCTV cameras, NVRs, APs, and their MAC addresses.

2. Configure Your Network Switches (Layer 2 & Layer 3):

• Create VLANs:

  (config)# vlan 100
  (config-vlan)# name CCTV-Cameras
  (config-vlan)# exit
  (config)# vlan 99
  (config-vlan)# name Network-Management
  (config-vlan)# exit
  

• Configure Access Ports (for NVRs, wired management devices):

  (config)# interface GigabitEthernet0/1
  (config-if)# switchport mode access
  (config-if)# switchport access vlan 99  # For NVR
  (config-if)# exit
  

• Configure Trunk Ports (for APs, inter-switch links):

  (config)# interface GigabitEthernet0/2
  (config-if)# switchport mode trunk
  (config-if)# switchport trunk encapsulation dot1q  # If needed
  (config-if)# switchport trunk allowed vlan 99,100 # Allow relevant VLANs
  (config-if)# exit
  

• Configure Layer 3 Switch SVIs (for Inter-VLAN Routing):

  (config)# interface vlan 100
  (config-if)# ip address 192.168.100.1 255.255.255.0
  (config-if)# no shutdown
  (config-if)# exit
  (config)# interface vlan 99
  (config-if)# ip address 192.168.99.1 255.255.255.0
  (config-if)# no shutdown
  (config-if)# exit
  

  (Ensure IP routing is enabled on the Layer 3 switch: ip routing)

3. Configure Wireless Access Points (APs):

• Create SSIDs:
  • One SSID for CCTV (e.g., CCTV-Secure).
  • One SSID for Management (if AP management needs to be on a separate wireless network).
• Map SSIDs to VLANs:
  • Map CCTV-Secure SSID to VLAN 100.
  • Map Management SSID to VLAN 99.
• Configure WPA3-Enterprise: Set authentication mode to WPA3-Enterprise, specify RADIUS server IP address and shared secret.

4. Configure Firewall/Router:

• Default Gateway: Ensure your Layer 3 switch/router is the default gateway for your VLAN subnets.
• ACLs: Implement strict ACLs on the Layer 3 device to control inter-VLAN traffic.
  • Example ACL for CCTV-Cameras (VLAN 100):
    • Permit 192.168.100.0/24 to 192.168.99.X (NVR IP) on port NVR_PORT (e.g., 554 RTSP, 80/443 HTTP).
    • Permit 192.168.100.0/24 to NTP server IP on UDP port 123.
    • Deny 192.168.100.0/24 to any other internal subnet.
    • Deny any ingress traffic to 192.168.100.0/24 except from 192.168.99.X (NVR/management).
  • Example ACL for Management (VLAN 99):
    • Permit specific management workstation IPs to NVR and APs on management ports (SSH, HTTPS).
    • Deny all other internal traffic.
  • Apply these ACLs to the SVI interfaces (inbound and outbound).

5. Configure NVR/VMS:

• Assign the NVR a static IP address within the Management VLAN (e.g., 192.168.99.10).
• Ensure the NVR’s gateway points to the SVI for VLAN 99 (e.g., 192.168.99.1).
• Configure the NVR to accept streams from the CCTV VLAN subnet.

Integrating WPA3-Enterprise with VLANs for Unparalleled Security

The true power emerges when WPA3-Enterprise and VLANs are combined. The RADIUS server, central to WPA3-Enterprise authentication, can also dynamically assign VLANs to authenticated devices. This means a camera presenting valid credentials is not only authenticated but is also placed into its correct, pre-defined CCTV VLAN automatically.

The Role of the RADIUS Server (NPS/FreeRADIUS)

A RADIUS server (e.g., Microsoft Network Policy Server (NPS) on Windows Server, or FreeRADIUS on Linux) performs the heavy lifting for WPA3-Enterprise:

1. Authentication: It verifies the credentials (username/password or certificate) presented by the wireless camera.
2. Authorisation: Based on policy, it determines what network access the authenticated device should have.
3. Accounting: It logs session details for auditing.

For dynamic VLAN assignment, the RADIUS server sends specific attributes back to the Access Point upon successful authentication:

• Tunnel-Type = VLAN
• Tunnel-Medium-Type = IEEE-802
• Tunnel-Private-Group-ID = [VLAN ID] (e.g., 100 for CCTV cameras)

This ensures that even if an attacker manages to get the WPA3-Enterprise credentials for a camera, they will only be placed into the highly restricted CCTV VLAN, further containing any potential breach.

Deployment Checklist for Secure Wireless CCTV

A systematic approach is crucial for a successful and secure deployment.

I. Planning Phase:

• Site Survey: Professional RF survey to determine optimal AP placement, minimise interference, and ensure adequate signal strength for all cameras. Document dead zones.
• Network Design: Comprehensive IP addressing scheme, VLAN ID assignments, subnet masks, and default gateways for each segment.
• RADIUS Server: Identify hardware/VM requirements. Select RADIUS solution (NPS, FreeRADIUS). Plan for Certificate Authority (CA) if using EAP-TLS.
• AP Selection: Ensure APs support WPA3-Enterprise, 802.1Q VLAN tagging, and 802.11w (MFP). Modern hardware is recommended for performance and security.
• CCTV Camera Compatibility: Verify all wireless cameras support WPA3-Enterprise (EAP-TLS recommended), 802.11w, and any specific Wi-Fi standards.
• NVR/VMS Compatibility: Confirm NVR/Video Management Software can integrate with separate VLANs and handle potentially segmented camera discovery.

II. Implementation Phase:

• Build RADIUS Server: Install OS, configure network settings.
• Install Certificate Authority (if EAP-TLS): Set up an internal CA, issue certificates for the RADIUS server and deploy client certificates to cameras (or generate for each camera if using a username/password type EAP method).
• Configure RADIUS Policies: Define connection request policies and network policies.
  • Connection Request Policy: Define criteria for requests (e.g., AP IP address range).
  • Network Policy: Define authentication method (EAP-TLS, PEAP-MSCHAPv2), user/computer groups, and RADIUS attributes for dynamic VLAN assignment (Tunnel-Type, Tunnel-Medium-Type, Tunnel-Private-Group-ID).
• Deploy and Configure APs:
  • Mount APs per site survey.
  • Configure management interface on the Management VLAN.
  • Create CCTV-Secure SSID, enable WPA3-Enterprise, point to RADIUS server (primary and secondary), configure shared secret for RADIUS communication.
  • Map CCTV-Secure SSID to VLAN 100.
  • Enable 802.11w (MFP).
• Configure Network Switches:
  • Create all defined VLANs (100, 99, etc.).
  • Configure switch ports connected to APs as 802.1Q trunk ports, allowing necessary VLANs.
  • Configure ports for NVRs/management workstations as access ports in VLAN 99.
  • Configure Layer 3 switch SVIs for inter-VLAN routing (VLAN 100, 99). Enable ip routing.
• Configure Firewall/Router:
  • Define default gateways for each VLAN.
  • Implement strict stateless and stateful Access Control Lists (ACLs) to control traffic flow between VLANs. Example: Only allow CCTV VLAN to stream to NVR in Management VLAN; block all other inter-VLAN traffic by default.
  • Ensure firewall rules align with least privilege principles.
• Configure CCTV Cameras:
  • Manually configure each camera for the CCTV-Secure SSID.
  • Input WPA3-Enterprise credentials (client certificate or username/password).
  • Set static IP addresses or ensure DHCP is providing addresses from the CCTV VLAN 100 subnet.
  • Configure NTP for accurate time synchronisation.
• Test Connectivity and Security Policies:
  • Verify cameras connect to the correct SSID and receive IP addresses from VLAN 100.
  • Confirm video streams reach the NVR.
  • Attempt to access cameras from non-authorised VLANs/devices to verify ACLs.
  • Test failover of RADIUS servers if applicable.

III. Post-Deployment and Maintenance:

• Firmware Updates: Establish a schedule for regular firmware updates for APs, cameras, NVRs, and network switches.
• Audit Logs: Regularly review RADIUS server logs, firewall logs, and NVR logs for suspicious activity.
• Backup Configurations: Maintain backups of all network device and server configurations.
• Security Audits/Penetration Testing: Consider periodic external security audits or penetration tests.
• ACL Review: Periodically review and update ACLs as network requirements change.
• Certificate Expiry Management: For EAP-TLS, implement a robust certificate lifecycle management process to prevent service disruptions due to expired certificates.

Considerations and Challenges

• Legacy Device Compatibility: Not all existing wireless CCTV cameras support WPA3-Enterprise. For mixed environments, consider a separate WPA2-Enterprise SSID on its own VLAN, or upgrade older cameras. A “mixed mode” (WPA2/WPA3 transition) on an SSID can introduce some WPA2 vulnerabilities.
• Complexity: WPA3-Enterprise and VLANs introduce a higher level of initial configuration complexity compared to simple PSK networks. This necessitates skilled network engineers or certified installers.
• Certificate Management: For EAP-TLS, managing certificates (issuance, revocation, renewal) for dozens or hundreds of cameras requires a well-planned PKI.
• Performance Overhead: WPA3’s advanced encryption can introduce a slight computational overhead on APs and cameras. However, for modern hardware, this impact is generally negligible and far outweighed by the security benefits.

Conclusion

The security of wireless CCTV networks can no longer be an afterthought. With the ever-increasing sophistication of cyber threats, relying on outdated or insufficient security protocols is a gamble no organisation can afford. Implementing WPA3-Enterprise, coupled with intelligent VLAN segmentation, represents a best-practice, engineering-grade approach to securing these vital surveillance assets.

By moving beyond shared passphrases and isolating CCTV traffic, we can significantly reduce the attack surface, prevent lateral movement in the event of a compromise, and ensure the integrity and confidentiality of surveillance data. While the initial setup may demand a higher level of expertise and planning, the long-term benefits in terms of security, reliability, and peace of mind are immeasurable.

As a UK-certified installer, I advocate for these robust solutions not just as an option, but as a mandatory standard for any serious wireless CCTV deployment.

Frequently Asked Questions (FAQ)

Q1: Can I use WPA3-Enterprise with existing WPA2-only cameras?

A1: WPA3-Enterprise is not directly backward compatible with WPA2-only clients on the same SSID in a “pure” WPA3 mode. Some Access Points offer a “WPA3 Transition Mode” which allows both WPA2 and WPA3 clients to connect to the same SSID. However, this transition mode means that the network is only as strong as its weakest link (WPA2 in this case), as an attacker could force WPA2 connections. For optimal security, it’s best to have a dedicated WPA3-Enterprise SSID for WPA3-capable cameras and, if absolutely necessary, a separate WPA2-Enterprise SSID on a different VLAN for legacy WPA2 devices. Ideally, legacy devices should be phased out or replaced.

Q2: What’s the minimum hardware requirement for implementing WPA3-Enterprise and VLANs?

A2: For WPA3-Enterprise, you’ll need:

1. Wireless Access Points: Modern APs supporting WPA3-Enterprise, 802.11w (MFP), and 802.1Q VLAN tagging.
2. CCTV Cameras: Wireless IP cameras that explicitly support WPA3-Enterprise (EAP-TLS is preferred).
3. RADIUS Server: A dedicated server (physical or virtual) running an operating system capable of hosting RADIUS software (e.g., Windows Server with NPS, or Linux with FreeRADIUS).
4. Network Switches: Managed Layer 2 switches (for VLAN tagging and trunking) and a Layer 3 switch or router (for inter-VLAN routing and ACLs).

For VLANs, any managed switch supporting 802.1Q is sufficient. The complexity increases with the need for inter-VLAN routing, requiring a Layer 3 device.

Q3: Is dynamic VLAN assignment necessary, or can I just use static VLANs?

A3: Dynamic VLAN assignment via RADIUS offers significant advantages, especially in larger deployments or those requiring granular control. It centralises VLAN policy management at the RADIUS server, automatically placing authenticated devices into their correct VLAN based on their credentials or certificate, reducing manual configuration on APs. It also provides greater flexibility and security by making it harder for an attacker to spoof a device’s identity and join the wrong VLAN. However, for smaller, static wireless CCTV networks, you could theoretically use static SSID-to-VLAN mappings on the APs, where each SSID corresponds to a specific VLAN. This approach does not offer the same level of granular device-specific control or security benefits of dynamic VLAN assignment with RADIUS. Dynamic VLAN assignment is strongly recommended for enterprise-grade security.

Q4: How does WPA3-Enterprise help against a camera being stolen or factory reset?

A4: WPA3-Enterprise provides significant protection even if a camera is stolen or factory reset:

1. No Shared Key Exposure: Unlike WPA2-Personal, there’s no shared passphrase that an attacker could extract to compromise other devices. Each camera has unique credentials (often a client certificate or a unique username/password).
2. No Connection After Reset: If a camera is factory reset, it loses its WPA3-Enterprise configuration (credentials/certificate). It cannot automatically rejoin the secure network without being reconfigured and re-authenticated with valid credentials from the RADIUS server. This prevents an attacker from simply resetting a stolen camera and connecting it to the network to gain access.
3. Credential Revocation: If a camera is stolen, its specific credentials or certificate can be immediately revoked on the RADIUS server, ensuring it can never reconnect to the network, even if an attacker manages to reconfigure it. This provides a much higher level of control and security compared to simply changing a PSK.
