Move unscannable

An Add-On implements the move action.

Setup

Install Add-On (requires a running bucketAV installation)

  1. Set the Stack name to bucketav-move-no.
  2. Set the BucketAVStackName parameter to the stack name of bucketAV (if you followed the docs, the name is bucketav).
  3. Set the TargetBucketName parameter to an existing S3 bucket where unscannable files are stored.
  4. Select I acknowledge that AWS CloudFormation might create IAM resources.
  5. Click on the Create stack button to save.

Multi-account setup

This plugin supports a multi-account setup.

IAM role-based access requires version >= 2.4.0 of this Add-On.

In case you are using the recommended IAM role-based access, the add-on works out of the box across AWS accounts. Only when the source bucket does not belong to the same AWS account than the target/quarantine bucket, you need to configure a bucket policy. See IAM role-based access for add-ons.

In case you are using S3 bucket-policy-based access, the add-on requires a bucket policy on the target/quarantine bucket. See S3 bucket-policy-based access for add-ons.

Not available. Please contact us if you have a use case for it!

Architecture

The following AWS services are used:

  • SNS Subscription to connect to the Findings Topic.
  • Lambda Function to move the unscannable files into the target bucket.
  • CloudWatch Alarms to monitor the used AWS services.
  • CloudWatch Logs to store logs.

Limitations

  • S3 object ACLs are not preserved. Instead, we set the ACL bucket-owner-full-control.

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://s3.REGION.amazonaws.com
https://states.REGION.amazonaws.com
https://dynamodb.REGION.amazonaws.com (only if AWS account connections are used)
https://ssmmessages.REGION.amazonaws.com (only if AWS account connections are used)
https://secretsmanager.REGION.amazonaws.com (only when scanning Cloudflare R2 buckets)

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