Amazon Connect attachment scanning

This feature is only available for bucketAV for Amazon S3!

You can configure Amazon Connect to scan attachments that are sent during a chat or uploaded to a case. You can scan attachments for malware before they are approved to be shared between participants of a chat with bucketAV.

The following figure shows an interaction between a user and an agent. The user (on the left) uploads a clean file first, followed by a virus. The agent (on the right) only receives the clean file.

Architecture

The following AWS services are used:

  • DynamoDB Table to store scan results temporarily.
  • SNS Subscription to connect to the Findings Topic.
  • Lambda Function to store the scan results in DynampDB and to implement the Amazon Connect attachment scanner.
  • CloudWatch Alarms to monitor the used AWS services.
  • CloudWatch Logs to store logs.

Run Lambda in a VPC

By default, the add-on deploys Lambda functions with access to the Internet. In case you want to deploy the Lambda functions into a VPC, configure the LambdaVpc and LambdaSubnets parameters.

The add-on requires access to the following endpoints (replace REGION with the AWS region like eu-west-1):

https://dynamodb.REGION.amazonaws.com

Ensure that the subnets configured in the LambdaSubnets parameter have access to these endpoints via a NAT Gateway or VPC Endpoints.
