1. Anomaly Detection with AWS GuardDuty for AI Behavior Analysis

    Python

    AWS GuardDuty is a threat detection service that continuously monitors your AWS accounts and workloads for malicious activity. It uses machine learning, anomaly detection, and integrated threat intelligence to identify and prioritize potential threats. GuardDuty analyzes events across AWS data sources, such as AWS CloudTrail event logs, Amazon VPC flow logs, and DNS logs.

    To set up anomaly detection with AWS GuardDuty for AI behavior analysis, we'll need to follow these steps:

    1. Create a GuardDuty Detector: This is the primary resource for GuardDuty, which analyzes and processes the data it ingests.
    2. Configure a ThreatIntelSet: ThreatIntelSets are feeds of known bad IP addresses and domains. GuardDuty can compare traffic against these feeds to identify potential threats.
    3. Use Findings to analyze behavior: GuardDuty generates findings when it detects unexpected and potentially unauthorized or malicious activity within your AWS environment. These findings need to be processed by your AI behavior analysis model, which is outside the scope of Pulumi.

    Below you'll find a Pulumi program written in Python that sets up a GuardDuty detector and configures a ThreatIntelSet.

    import pulumi import pulumi_aws as aws # Initialize a GuardDuty detector detector = aws.guardduty.Detector("aiDetector", enable=True) # Assuming we have a ThreatIntelSet data source, e.g., an S3 bucket with threat intelligence indicators, # we will just mention a placeholder as LOCATION_OF_THREAT_INTELSET. threat_intel_set = aws.guardduty.ThreatIntelSet("aiThreatIntelSet", activate=True, detector_id=detector.id, format="TXT", # The format of the file that contains the ThreatIntelSet data location="LOCATION_OF_THREAT_INTELSET", # The URI of the file that contains the ThreatIntelSet data ) # Export the GuardDuty detector ID pulumi.export('detector_id', detector.id) # Depending on the findings, you might want to send them to a separate system # (like an S3 bucket, a Lambda function, or a log analysis service) where you can # run your AI behavior analysis. # For now, we're just setting up GuardDuty. The actual response based on findings # would need to be created separately and depends on your specific AI tools and requirements.

    In this program:

    • We create a GuardDuty Detector resource which will start analyzing the accounts specified for suspicious behavior.
    • We then configure a ThreatIntelSet, a resource representing a list of known malicious IP addresses and domains. It is activated by setting the activate argument to True, and we must provide the location (S3 URI) and the format of the threat intelligence set (for example, a text file with a list of indicators). Please replace "LOCATION_OF_THREAT_INTELSET" with the actual S3 URI of your threat intelligence feed.
    • We export the detector ID so that you can use it in other parts of your infrastructure, such as a SIEM system or a custom alerting mechanism.

    Please note that this is a basic setup, and AWS GuardDuty offers a lot more features and customization you can take advantage of. For the AI behavior analysis part, once GuardDuty detects an anomaly, you'll need to feed these detections into your AI system. This integration is not covered by Pulumi and would require a custom implementation.

    To use this Pulumi program:

    1. Ensure AWS CLI is configured with appropriate credentials and default region.
    2. Install Pulumi CLI and set up the Pulumi program in a directory.
    3. Replace "LOCATION_OF_THREAT_INTELSET" with your actual S3 URI.
    4. Run pulumi up to preview and deploy the resources.
    5. Implement your AI behavior analysis outside of Pulumi that can use these GuardDuty findings.
