Producing Artificial Safety Information 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 surroundings consisting of assorted related units equivalent to sensible residence home equipment, industrial sensors, and wearable units. The log entries ought to embrace various kinds of occasions, together with: 
1. System authentication and connection occasions (profitable and failed makes an attempt) 
2. System telemetry and sensor information transmissions 
3. Community 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/check/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 certain that the generated log entries are various, real looking, and consultant of assorted IoT safety situations, together with each benign and malicious actions. The artificial information also needs to keep the statistical properties and patterns present in real-world IoT safety logs.
