Disable the Trend Cloud One File Security Storage EventBridge rule
Disable a rule with a prefix matching “<C1FSS-StackName>-OnS3ObjectCreatedRule”. The <C1FSS-StackName> default value is “Account-Scanner-TM-FileStorageSecurity”.
If you have customized the stack name, find the stack name that you entered in your
Trend Cloud One File Storage Security deployment.
Enable the EventBridge
When you add a region to File Security Storage, the scanner is automatically deployed
in that region. However, you need to turn on EventBridge in each bucket to allow the
scanner access to the files being uploaded to that bucket. When EventBridge is turned
on, File Security can scan that bucket. File Security cannot scan a bucket when the
Status is EventBridge off or Scanner is not deployed.
Procedure
- In Trend Vision One, go to , and select the account.
- Select the region.
- Select the buckets in which you want to enable EventBridge.
- From the Change Status list, select Turn on EventBridge.
- Verify the selected buckets.
- Select Turn On EventBridge.The Status changes to EventBridge on and the indicator circle turns green.
Test upload sample files into protected S3 buckets
You should run the test by uploading 1 eicar file and 1 clean file.
Procedure
- Verify if the scan result is tagged correctly on the S3 files: clean file:
{ "fss-scan-detail-code": 0, "fss-scan-date": "YYYY/MM/DD hh:mm:ss", "fss-scan-result": "no issues found", "fss-scan-detail-message": "-", "fss-scanned": true }
malicious file (eicar){ "fss-scan-detail-code": 0, "fss-scan-date": "YYYY/MM/DD hh:mm:ss", "fss-scan-result": "malicious", "fss-scan-detail-message": "-", "fss-scanned": true }
- Verify if the scan results are successfully sent to Trend Vision One File Security.
- The AWS accounts and S3 buckets are displayed on the Inventory tab.
- The scan statistics and detection are displayed on the Scan Activity tab.
If Trend Vision One File Security Storage works, remove the Cloud One File Storage Security Stack.
