Frequently Asked Questions

Is Trellix a secure platform?
Yes. The Trellix platform uses a multi-tiered approach to addressing industry best practices for security risk management and utilizes guidelines derived from IEEE, IEC, NEMA, DoD, and UL2900 to achieve a secure and adaptable IoT platform. The Trellix IoT platform leverages the WaveLinx system which was also the first connected lighting system to carry the UL2900-1 cybersecurity listing for network controllable devices. 

What are the tiers for security?
Trellix uses a seven-layer multi-tiered security approach that includes industry best practices, Trellix ingenuity and the customer as a partner.

  • Physical security
  • Customer security
  • Device communication security
  • Network communication security
  • Network segmentation security
  • OTA update security
  • COE assurance

Review the Trellix statement of security document for more information on each of these seven layers.

Why is physical security so important?
Physical security is a partnership between Trellix and the customer. The Trellix platform includes multiple security measures in the devices. Physical access at the customer location is the first step, and we provide guidance to the customer on how to secure this. Physical access to a device may provide the ability for a potential attack

Does Trellix provide a path to my building intranet (LAN)?
The WaveLinx Wireless Area Controller (WAC) and the Trellix Core are the only devices that connect physically to the building intranet. In addition to other security measures the WAC and the Trellix Core isolate the wired Ethernet network from the wireless network which limits the possibility of someone using the Trellix system to gain confidential business information.

Why AES 128-bit encryption, why not AES 256-bit?
Wavelinx devices use AES 128-bit encryption for device-to-device communications as recommended by the National Institute of Standard and Technology (NIST). 

AES encryption comes in three standard key sizes (128, 192 and 256bits). Many people think because there are three sizes AES 256-bit must be better. In fact, there were three keys sizes because it was developed for US Military/Government communications which requires three security levels. 

AES 128-bit encryption uses a 128-bit key to encrypt the data. That is 3.4 x 1038 possible combinations if someone wanted to brute force guess your encryption key. Assuming you were able to guess the correct key 50% of the way through the combinations it would still take over 1 billion years.

Can someone send a command or take over one of the WaveLinx devices?
No. All WaveLinx devices use AES 128-bit encryption and require that the commands be sent only to and from the WaveLinx Wireless Area Controller (WAC).

If someone were to hack into my Wireless Area Controller, can they see the rest of my system or my building intranet (LAN)?
No, each Wireless Area Controller employs its own unique key, which limits potential breaches to only a small area. Also, the WAC provides segmentation between the lighting Operational Technology (OT) network and the enterprise Information Technology (IT) network. Even if an attack within the lighting (OT) network and its devices is successful, the WAC isolates the enterprise IT network from potential attack.

Are firmware updates secure?
Yes, Trellix firmware updates are securely transmitted which means that only our over the air (OTA) firmware updates will be accepted by each device.

If there is a security issue in the future how will we know?
The Cooper Lighting Solutions Cybersecurity (CLSC) maintains a publicly available website for information and feedback concerning cybersecurity threats and responses. The CLSC also independently evaluates Cooper Lighting IoT products for vulnerabilities as new cybersecurity threats are exposed.

Is Trellix Locate secure and is the data transmitted by the Tags secure?
Trellix Locate consists of two components: Software and infrastructure. The software component manages the system (engine, database, software). The Trellix Locate software, which can be an on-premise installation, is similar to any other system inside the hospital. Trellix Locate software is updated to keep current with the latest OS and all security patches and enhancements. 

The infrastructure component is a more unique aspect of RTLS. The infrastructure consists of RTLS tags that communicate wirelessly to sensors, so the security of that communication and of the devices is essential. We keep our hardware as simple as possible. The majority of our tags use uni-directional beaconing, which does not require them to authenticate with the network; in other words, they do not have direct network access. The data sent by the tags is limited to its location, product health (battery level) and its identification number. Our tags to not communicate personnel information or client information.

What are the Trellix Locate design best practices?

NOTE: Sensors include WTA (Wireless Tile Mount Kit) , WTH (Wireless Tile mount Sensor), WAA (Integrated Fixture sensor).

Can WaveLinx communicate through interior walls?
Yes, WaveLinx will communicate through two to three interior walls of standard sheetrock construction with wood or aluminum framing.

Can sensors be disabled?
Yes, Integrated or external sensors can be disabled or have the sensitivity adjusted.

Does the Wireless Area Controller (WAC) need to be installed in the space or can it be installed in the Plenum?
The WAC can be installed in the plenum above the drop ceiling and will communicate to the devices in the space. It should not be installed on or next to a metal or concrete wall.

Should I install the WAC next to a concrete or metal wall?
No. Concrete or metal walls severely impact the strength of the wireless signal and will reduce the overall coverage and performance of the WaveLinx system. The WAC should be installed in the center of the overall space that it will be controlling.

Should I install the WAC in an Electrical Closet or IT room?
No, these types of rooms are typically surrounded by concrete walls. Concrete walls severely impact the strength of the wireless signal and will reduce the overall coverage and performance of the WaveLinx system. The WAC should be installed in the center of the overall space that it will be controlling.

How does WaveLinx communicate through or around concrete spaces, like stairwells and electrical closets?
The Wireless Area Controller emits a wireless signal using the 802.15.4 wireless protocol on the 2.4Ghz frequency range. This signal pulses out from the WAC in a wireless bubble. Concrete or metal structures will break this bubble. Ensure that the WAC is placed at least 15 feet away from these structures to allow the wireless signal to have the best angle around these structures. In addition, most WaveLinx devices act as a signal repeater which will allow the wireless signal to communicate around difficult spaces.

What is the maximum distance the WaveLinx system can communicate?
The Wireless Area Controller can control a maximum 60 WaveLinx devices within 150 feet line of sight (LOS). If you have not reached the 60-device limit within 150ft, wireless hopping will allow you to reach additional devices up to the 60-device maximum. Each line voltage powered wireless device can act as a signal repeater or (hopper) and provide an additional 75 feet of wireless coverage if the device is within 75ft of a device or within 150ft range of the WAC. Trellix Locate supports a maximum of 3 hops each adding 75ft of coverage beyond the WAC 150ft range.

Can WaveLinx be installed in the same area as the building Wi-Fi?
Yes, although 802.15.4 communications using a similar frequency as standard Wi-Fi it uses different channels, modulation and communications structure. This reduces the risk of conflicts of wireless systems

Can multiple 802.15.4 wireless networks exist in the same area of a building?
Yes, 802.15.4 is self-healing, auto channel selecting mesh network. This means that these networks can coexist if set up correctly. In addition, WaveLinx devices will only communicate with the assigned Wireless Area Controller. Other 802.15.4 wireless networks may not include all the security and performance qualities of WaveLinx and may not perform as well.

Is the connection to Trellix Core wireless?
No. the Wireless Area Controller are Power over Ethernet (PoE) and share information over a wired Ethernet connection to the Trellix Core.

What kind of sensor distribution is required to achieve room level accuracy?
To achieve room level accuracy, we recommend at least 4 sensors be placed integrated into lighting fixtures and/or tile mount sensor in the room. In open areas, sensors shall be installed 8 feet or less apart in X and Y direction to get good location accuracy. 

For Room level accuracy it is also recommended that the sensors be installed within 1m (3 ft) of each corner of a room. In a room with all fixture mount(integrated) sensors, place one additional tile mount sensor in the middle of the room to improve room-level accuracy
