Producing Artificial Safety Knowledge for IoT

On this weblog submit, we’re going to make use of Amazon Bedrock with Anthropic Claude 3 Sonnet to generate artificial log information. Right here is an instance of a immediate to Amazon Bedrock:

Create a python operate that generates artificial safety log entries for an AWS IoT atmosphere consisting of assorted related units corresponding to sensible dwelling home equipment, industrial sensors, and wearable units. The log entries ought to embody several types of occasions, together with: 
1. Machine authentication and connection occasions (profitable and failed makes an attempt) 
2. Machine telemetry and sensor information transmissions 
3. Community site visitors patterns (regular and anomalous) 
4. Safety incidents and potential assaults (e.g., unauthorized entry makes an attempt, malware detection, distributed denial-of-service (DDoS) assaults) 
5. System and software log messages associated to safety occasions 

Every log entry ought to have the next format: 
{ "timestamp": "2024-07-23 16:51:17.384", "logLevel": "INFO", "traceId": "e2893ea0-8c00-b560-5e71-9fb35a9654c2", "accountId": "123456789012", "standing": "Success", "eventType": "Publish-Out", "protocol": "MQTT", "topicName": "/iot/take a look at/machine", "clientId": "virtualDevice1", "principalId": "ad4f9225b1753fc27feb79341bf13d17bedbd3f8d6514ba626bfb22d1851e472", "sourceIp": "1.2.3.4", "sourcePort": 36954 }

Right here is one other log instance:
{ "timestamp": "2024-07-23 16:38:46.504", "logLevel": "ERROR", "traceId": "c9c54f40-5d9a-6693-5ddf-d52fb16e514f", "accountId": "123456789012", "standing": "Failure", "eventType": "Join", "protocol": "MQTT", "clientId": "virtualDevice1", "principalId": "ad4f9225b1753fc27feb79341bf13d17bedbd3f8d6514ba626bfb22d1851e472", "sourceIp": "2.3.4.5", "sourcePort": 46028, "cause": "AUTHORIZATION_FAILURE", "particulars": "Authorization Failure" }

Moreover, be sure that the generated log entries are various, practical, and consultant of assorted IoT safety situations, together with each benign and malicious actions. The artificial information must also preserve the statistical properties and patterns present in real-world IoT safety logs.

The outcomes will be captured by way of the Amazon Bedrock chat playground, or accessed programmatically by way of the AWS APIs, corresponding to these highlighted beneath:
