LoRaWAN: An Introduction to Security Requirements
LoRaWAN is a Low-Power Wide Area Network (LPWAN) technology that enables secure and reliable communication between Internet of Things (IoT) devices. The technology provides long-range communication capabilities, making it ideal for IoT applications that require a low-power, low-cost, and secure network.
In this knowledge base (KB) article, we will provide an overview of the security requirements for a LoRaWAN network, and highlight the key aspects that organizations need to pay attention to when implementing a LoRaWAN network.
Security and Firewall Rules
To ensure that a LoRaWAN Gateway has access to the Internet and is properly segmented from
the rest of the customer network, the following actions should be taken:
- Limit incoming traffic to the Gateway from the customer network by creating rules that allow only certain traffic (e.g., specific IP addresses, ports, protocols).
- Enable logging for the firewall to track incoming and outgoing traffic and detect potential security threats.
- It is recommended to set up a network firewall to protect the network from external threats. This can be done by configuring the firewall on the network or by installing a separate firewall device.
- Allow outgoing traffic from the Gateway to the Internet through the firewall by creating a rule that allows traffic to be sent to any destination
| Protocol | Ports |

Authentication
Encryption
LoRaWAN uses Advanced Encryption Standard (AES) encryption to protect the confidentiality and integrity of data transmitted between the end devices and the network server. This ensures that sensitive data is protected from eavesdropping and tampering during transmission.
Network Server Authentication
The network server must authenticate end devices before allowing them to join the network. This is achieved through the use of unique device keys and a secure join procedure. The secure join procedure involves the exchange of cryptographic keys between the end device and the network server, ensuring that only authorized devices can join the network.
Message integrity
LoRaWAN uses a message integrity code (MIC) to verify the
integrity of each message transmitted between sensors and the central network server.
Conclusion
Overall, LoRaWAN provides a secure and reliable communication method for low-power,
low-cost devices in a wide area network. The use of a centralized gateway and various security
features helps to protect the communication between the sensors and the central network
server.
