Move infected (quarantine)

An Add-On implements the quarantine action. By default, the Add-On does not quarantine unscannable files. You can change this via the QuarantineUnscannableFiles configuration parameter.

Setup (#)

The DeleteInfectedFiles configuration parameter of the bucketAV stack must be set to false.

Install Add-On (requires a running bucketAV installation)

  1. Set the Stack name to bucketav-quarantine.
  2. Set the BucketAVStackName parameter to the stack name of bucketAV (if you followed the docs, the name is bucketav).
  3. Set the QuarantineBucketName parameter to an existing S3 bucket where quarantined files are stored.
  4. Select I acknowledge that AWS CloudFormation might create IAM resources.
  5. Click on the Create stack button to save.

Architecture (#)

The following AWS services are used:

  • SNS Subscription to connect to the Findings Topic.
  • Lambda Function to move the infected files into the quarantine 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.
