Habilite el registro CloudTrail de eventos de datos para los recursos de Amazon Bedrock AgentCore Gateway

Para habilitar CloudTrail los eventos de datos para los recursos de puerta de enlace mediante la AWS CLI, puede ejecutar el siguiente comando en una terminal:

aws cloudtrail put-event-selectors \
  --trail-name brac-gateway-canary-trail-prod-us-east-1 \
  --region us-east-1 \
  --advanced-event-selectors '[
    {
      "Name": "GatewayDataEvents",
      "FieldSelectors": [
        {
          "Field": "eventCategory",
          "Equals": ["Data"]
        },
        {
          "Field": "resources.type",
          "Equals": ["AWS::BedrockAgentCore::Gateway"]
        }
      ]
    }
  ]'

El siguiente ejemplo muestra cómo crear un CloudTrail registro con eventos de datos de AgentCore Gateway mediante el AWS CDK:

import { Construct } from 'constructs';
import { Trail, CfnTrail } from 'aws-cdk-lib/aws-cloudtrail';
import { Bucket } from 'aws-cdk-lib/aws-s3';
import { Effect, PolicyStatement, ServicePrincipal } from 'aws-cdk-lib/aws-iam';
import { RemovalPolicy } from 'aws-cdk-lib';

export interface DataEventTrailProps {
  /**
   * Whether to enable multi-region trail
   */
  isMultiRegionTrail?: boolean;

  /**
   * Whether to include global service events
   */
  includeGlobalServiceEvents?: boolean;

  /**
   * AWS region
   */
  region: string;

  /**
   * Environment account ID
   */
  account: string;
}

/**
 * Creates a CloudTrail trail configured to capture data events for Bedrock Agent Core Gateway
 */
export class BedrockAgentCoreDataEventTrail extends Construct {
  /**
   * The CloudTrail trail
   */
  public readonly trail: Trail;

  /**
   * The S3 bucket for CloudTrail logs
   */
  public readonly logsBucket: Bucket;

  constructor(scope: Construct, id: string, props: DataEventTrailProps) {
    super(scope, id);

    // Create S3 bucket for CloudTrail logs
    const bucketName = `brac-gateway-cloudtrail-logs-${props.account}-${props.region}`;
    this.logsBucket = new Bucket(this, 'CloudTrailLogsBucket', {
      bucketName,
      removalPolicy: RemovalPolicy.RETAIN,
    });

    // Create trail name (suffixing region since regional trail)
    const trailName = `brac-gateway-trail-${props.region}`;

    // Add CloudTrail bucket policy
    this.logsBucket.addToResourcePolicy(
      new PolicyStatement({
        sid: 'AWSCloudTrailAclCheck',
        effect: Effect.ALLOW,
        principals: [new ServicePrincipal('cloudtrail.amazonaws.com')],
        actions: ['s3:GetBucketAcl'],
        resources: [this.logsBucket.bucketArn],
        conditions: {
          StringEquals: {
            'aws:SourceArn': `arn:aws:cloudtrail:${props.region}:${props.account}:trail/${trailName}`,
          },
        },
      }),
    );

    this.logsBucket.addToResourcePolicy(
      new PolicyStatement({
        sid: 'AWSCloudTrailWrite',
        effect: Effect.ALLOW,
        principals: [new ServicePrincipal('cloudtrail.amazonaws.com')],
        actions: ['s3:PutObject'],
        resources: [this.logsBucket.arnForObjects(`AWSLogs/${props.account}/*`)],
        conditions: {
          StringEquals: {
            's3:x-amz-acl': 'bucket-owner-full-control',
            'aws:SourceArn': `arn:aws:cloudtrail:${props.region}:${props.account}:trail/${trailName}`,
          },
        },
      }),
    );

    // Create CloudTrail trail
    this.trail = new Trail(this, 'GatewayDataEventTrail', {
      trailName,
      bucket: this.logsBucket,
      isMultiRegionTrail: props.isMultiRegionTrail ?? false,
      includeGlobalServiceEvents: props.includeGlobalServiceEvents ?? true,
      enableFileValidation: true,
    });

    // Add advanced event selectors for Bedrock Agent Core Gateway data events
    const cfnTrail = this.trail.node.defaultChild as CfnTrail;

    // Define the advanced event selectors
    const advancedEventSelectors = [
      {
        // Log Bedrock Agent Core Gateway Data Events only
        fieldSelectors: [
          {
            field: 'eventCategory',
            equalTo: ['Data'],
          },
          {
            field: 'resources.type',
            equalTo: ['AWS::BedrockAgentCore::Gateway'],
          },
        ],
      },
    ];

    // Clear any existing event selectors and set advanced event selectors
    cfnTrail.eventSelectors = undefined;
    cfnTrail.advancedEventSelectors = advancedEventSelectors;
  }
}
