Configure Cloud Storage Scanning for Box in Nebula

Cloud Storage Scanning supports scanning for malicious files in your enterprise level Box account. Configure a continuous or scheduled scan to check for any malicious files currently in your users' Box folders.

The following scan frequencies are available:

  • On-Demand: An on-demand scan of your cloud storage folders. Click Scan under the Actions column on the Cloud Storage Scans page to initiate the scan.
  • Daily: A scheduled scan that runs daily at the specified time. 
  • Weekly: A scheduled scan that runs on certain days of the week at the specified time.
  • Monthly: A scheduled scan that runs on a certain day of the month at the specified time.
  • Continuous: A continuous scan that checks for new and updated files. Check Include existing files to initiate a scan on all files before monitoring for changes to them. 

For more information, see Should I run a scheduled scan, continuous scan, or a combination of both.
