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 knowledge. 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 similar to good residence home equipment, industrial sensors, and wearable gadgets. 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 knowledge 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/check/gadget", "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, be sure that the generated log entries are numerous, practical, and consultant of varied IoT safety eventualities, together with each benign and malicious actions. The artificial knowledge also needs to preserve the statistical properties and patterns present in real-world IoT safety logs.

The outcomes could be captured by the Amazon Bedrock chat playground, or accessed programmatically by the AWS APIs, similar to these highlighted under:

import boto3
import json

bedrock = boto3.consumer(service_name="bedrock-runtime",region_name="us-west-2")

immediate=""''''

physique = json.dumps({
    "messages" : [
        { 
            "role" : "user",
            "content" : "prompt"
        }],
    "anthropic_version": "bedrock-2023-05-31",
    "max_tokens": 2000,
    "temperature": 0.75,
    "top_k" : 250
})

response = bedrock.invoke_model(
    modelId='anthropic.claude-3-sonnet-20240229-v1:0',
    contentType="software/json",
    settle for="software/json",
    physique=physique
)

response_body = json.masses(response['body'].learn())
print(response_body['content'][0]['text'])

Provided that generative AI fashions aren’t deterministic, your response could differ, however it would possible be just like the code proven under:

Here is a Python operate that generates artificial safety log entries for an AWS IoT surroundings primarily based in your necessities:

```python

    event_types = ["Connect", "Disconnect", "Publish-In", "Publish-Out", "Subscribe", "Unsubscribe"]
    protocols = ["MQTT", "HTTP", "WebSocket"]
    subjects = ["/iot/device/telemetry", "/iot/device/status", "/iot/device/command"]
    client_types = ["smartHome", "industrial", "wearable"]
    account_ids = ["123456789012", "234567890123", "345678901234"]
    status_options = ["Success", "Failure"]

    # Generate random values
    timestamp = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S.%f")[:-3]
    log_level = random.selection(log_levels)
    trace_id = str(uuid.uuid4())
    account_id = random.selection(account_ids)
    standing = random.selection(status_options)
    event_type = random.selection(event_types)
    protocol = random.selection(protocols)
    topic_name = random.selection(subjects)
    client_type = random.selection(client_types)
    client_id = f"{client_type}System{random.randint(1, 1000)}"
    principal_id = uuid.uuid4().hex
    source_ip = str(ipaddress.IPv4Address(random.randint(0, 2**32 - 1)))
    source_port = random.randint(1024, 65535)

    # Create the bottom log entry
    log_entry = {
        "timestamp": timestamp,
        "logLevel": log_level,
        "traceId": trace_id,
        "accountId": account_id,
        "standing": standing,
        "eventType": event_type,
        "protocol": protocol,
        "clientId": client_id,
        "principalId": principal_id,
        "sourceIp": source_ip,
        "sourcePort": source_port
    }

    # Add event-specific particulars
    if event_type in ["Publish-In", "Publish-Out", "Subscribe", "Unsubscribe"]:
        log_entry["topicName"] = topic_name

    if standing == "Failure":
        log_entry["reason"] = "AUTHORIZATION_FAILURE"
        log_entry["details"] = "Authorization Failure"

    # Add security-specific occasions
    if random.random() 

This python operate generates IoT safety logs which you can now ship to Amazon Easy Storage Service (Amazon S3) to question with Amazon Athena, use Amazon Quicksight to visualise the info, or combine quite a lot of AWS companies to work with the info as you see match. That is additionally simply an instance, and we encourage you to work with the immediate to suit your organizations wants, as there are a number of use circumstances. For instance, you may add the extra sentence to the top of the immediate: “Additionally, the python operate ought to write to an Amazon S3 bucket of the consumer’s selecting” to switch the python operate to jot down to Amazon S3.
