Producing Artificial Safety Knowledge for IoT

On this weblog put up, 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 surroundings consisting of varied linked gadgets akin to sensible dwelling home equipment, industrial sensors, and wearable gadgets. The log entries ought to embrace 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 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, "cause": "AUTHORIZATION_FAILURE", "particulars": "Authorization Failure" }

Moreover, be sure that the generated log entries are numerous, reasonable, 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 means of the Amazon Bedrock chat playground, or accessed programmatically by means of the AWS APIs, akin to these highlighted under:
