Verify scanner health
Each month or quarter, do these actions to review IVA Scanner and Arctic Wolf® Agent scanning health:
Check IVA Scanner connectivity
Arctic Wolf alerts you if IVA Scanners go offline, but you should also verify that online IVA Scanners are working as expected and that assets are scanned on time.
For each scanner you want to verify, complete these steps:
Check the IVA Scanner rate
Make sure assets are scanned with an appropriate interval. In general, a scanner scans approximately 150–250 assets in an 8-hour period. This number changes based on the type of system and environment. For example, if several large subnets of assets are only given a weekly scan for an 8-hour scan window, it can take more than a month to complete a full cycle of scanning. If you have concerns about your environment not being scanned in a timely manner, contact your CST at security@arcticwolf.com to review your scan scheduling.
To optimize scanning without increasing the scan window time, you can deploy additional physical scanners. This would allow you to scan multiple subnets in parallel. Adding resources to virtual scanners would not result in any meaningful increase in scan throughput because they would consume additional resources.
See Managed Risk Scanner FAQ for more information.
Check Agent scanning health
Agent scans are set and managed by your CST, but you can view the results of Agent scans and identify assets that were scanned or missed.
