Amazon Connect attachment scanning

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.

Setup

Requires bucketAV powered by ClamAV® version >= 2.9.0 or bucketAV powered by Sophos® version >= 2.0.0. To update to the latest version, follow the Update Guide.

The ReportCleanFiles configuration parameter must be set to true.

Install Add-On (requires a running bucketAV installation)

1. Set the Stack name to bucketav-connect.
2. Set the BucketAVStackName parameter to the stack name of bucketAV (if you followed the docs, the name is bucketav).
3. Select I acknowledge that AWS CloudFormation might create IAM resources.
4. Click on the Create stack button to save.
5. Wait for the stack to reach status CREATE_COMPLETE.
6. Click on the Outputs tab to get the ScannerLambdaFunctionName.
7. Follow the Amazon Connect documentation to add an attachment scanner to your Amazon Connect instance and select the Lambda function returned in the previous step.

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.
