Automatic updates
If you observe that your AWS Lambda functions have been updated by File Storage Security, this is expected behavior.
The Trend Micro backend service regularly pushes updates to File Storage Security stacks on AWS.
| Automatic update | Stack | AWS component | When |
|---|---|---|---|
| Licence | Scanner | Lambda layer | Weekly |
| Lambda (feature) | Scanner; storage (two Lambdas)* | Lambda code | Whenever the code is patched (see What's New) |
| Security update: malware patterns | Scanner | Lambda layer | Daily |
* ScannerLambda in scanner stacks; BucketListenerLambda and PostScanActionTagLambda in storage stacks
To manually update stacks, see Update stacks.
