WorkloadSecurity-AWS-SNS Integration

CloudFormation template for Trend Micro Cloud One Workload Security Events - Amazon SNS Integration

Setup Instructions

Step 1: Create a Cloud One Workload Security API Key. Refer to the Workload Security documentation for steps to create this API key - https://cloudone.trendmicro.com/docs/workload-security/api-send-request/#create-an-api-key

Step 2: Run the CloudFormation template workloadsecurity-events-aws-sns-cloudformation.json

How it works

The CloudFormation template creates the following resources -

• Amazon SNS Topic

  • Workload Security sends security events from various Workload Security modules, like System, Anti-Malware, Web Reputation, Application Control, Integrity Monitoring, Log Inspection, Firewall and Intrusion Prevention (IPS) events.
  • SNS Messages are encrypted with the Default AWS Managed key (AWS-CMK) for SNS (arn:aws:kms:<AWS::Region>:<AWS::AccountId>:alias/aws/sns).

• AWS Lambda Function (C1WSLambdaSnsS3Writer)

  • Compute to read Amazon SNS messages and write the security events to Amazon S3 bucket.
  • Can be used to action auto-remediation tasks within the environment. Some use-cases may be included in this code repository.

• Amazon S3 Bucket

  • Storage location for security events.
  • Can be queried with Amazon Athena.
  • Objects are encrypted by default with the Default SSE-S3 encryption.
  • Objects can only be accessed via HTTPS.

• IAM User

  • Creates an IAM User for Workload Security to post to SNS Topic.

• IAM User Access Key

  • Required. Access and secret keys for the IAM User to authenticate AWS API calls.
  • Access and secret keys are never shared in the CloudFormation Outputs section and sent directly to Workload Security using APIs.

• AWS IAM Policy for SNS

  • Permissions for the IAM User to publish to the SNS Topic.

• AWS Lambda Function (C1WSConfigureSIEMLambdaFunction)

  • Configuration logic to call Workload Security APIs and configure Workload Security for SNS Event Forwarding.
  • You can see the configuration on the Workload Security Console: Administration > System Settings > Event Forwarding

• Custom CloudFormation Resource (CloudOneWorkloadSecurityConfigResource)

  • Runs the configuration logic during Create and Update Stack to populate the following fields on the Workload Security console.
    • SNS Topic Arn
    • Access key and
    • Secret key

• AWS IAM Role for Lambda functions

  • Use the AWS Managed Policy "AWSLambdaBasicExecutionRole" for AWS Lambda.

• AWS IAM Policy for Lambda Service

  • Permissions for the Lambda functions to write to the created S3 bucket.
