Producing Artificial Safety Knowledge for IoT

On this weblog publish, 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 perform that generates artificial safety log entries for an AWS IoT setting consisting of varied related units resembling sensible dwelling home equipment, industrial sensors, and wearable units. The log entries ought to embody various kinds of occasions, together with: 
1. Gadget authentication and connection occasions (profitable and failed makes an attempt) 
2. Gadget 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 utility 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/system", "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, "motive": "AUTHORIZATION_FAILURE", "particulars": "Authorization Failure" }

Moreover, make sure that the generated log entries are various, life like, and consultant of varied IoT safety eventualities, 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, resembling these highlighted under:
