Connect your devices to AWS IoT using LoRaWAN

For many IoT use-cases, sensors only ever need to transmit infrequent and low bit-rate data. These sensors may communicate over large distances and have battery lives spanning in years, which means they are replaced infrequently. A couple of common use-cases would be in Smart Cities (eg. Parking or Waste sensors) and Agriculture (eg. Soil Monitoring […]

Configuring Cognito User Pools to Communicate with AWS IoT Core

AWS IoT Core supports certificate-based mutual authentication, custom authorizers, and Amazon Cognito Identity as way to authenticate requests to the AWS IoT device gateway. Amazon Cognito User Pools was made generally available last year. It allows customers to easily add user sign up and sign in to mobile and web apps. You can use Cognito […]

Detect anomalies on connected devices using AWS IoT Device Defender

We often see security breaches depicted in media and popular culture. In the HBO series Silicon Valley, a compromised refrigerator is used by hacker Gilfoyle to run a malicious piece of software. The reality of connected devices isn’t very different from this fictitious scenario. The compromised refrigerator can send consumer data to unauthorized endpoints. Connected […]

Perform Protocol Conversion at the Edge with AWS Lambda and AWS Greengrass

In industrial automation, you will find dozens of protocols used by devices and PLC vendors: OPC-UA, Modbus TCP, serial, and more. In fact, often in just one facility, it is common to find two similar processes performing the same function with different equipment. AWS Greengrass reduces the operational overhead for businesses to change protocols as […]

Ensure Secure Communication with AWS IoT Core Using the Certificate Vending Machine Reference Application

X.509 certificates are used to ensure secure communication between IoT devices and AWS IoT Core. Devices use these certificates to connect to AWS IoT Core using TLS mutual authentication. AWS IoT Core uses TLS mutual authentication to encrypt data as it moves between AWS IoT Core and other devices or other AWS services. A X.509 certificate […]

How to Implement MQTT with TLS Client Authentication on Port 443 from Client Devices (Python)

Application Layer Protocol Negotiation (ALPN) is an extension to TLS that enables clients connecting to a TLS server to pass an extra parameter, known as a ProtocolNameList. The ProtocolNameList is a preference-ordered list of the application protocols that the client would like to use to communicate. AWS IoT Core now allows you to connect devices […]
