Enable Agentless Tracking
To reduce / suppress the duplicated assets because of dhcp, one of effective methods is to enable agentless tracking.
2.1. VM > Scans > Setup > Agentless Tracking > Accept
2.2. VM > Scans > Authentication > Edit [Your Authentication Record] > Login Credentials > “Enable Agentless Tracking”
2.3. VM > Users > Setup > Cloud Agent Setup > “Show unified view of hosts”
Note: QID 45179 for successfully checked tracking
QID 45180 – for failed
Change IP Tracked Host Assets to DNS Tracking
Qualys provides multiple mechanisms for tracking assets in your environment; IP, DNS, NetBIOS, Agent, and EC2. In Qualys IP tracking is the default mechanism. DNS and NetBIOS tracking are most useful for DHCP networks.
Note:
- Qualys Article Number: 000002856
- Understanding IP, DNS, and NetBIOS Tracking and Scan by Hostname
- Change IP tracking method from IP to DNS, it will require to remove all hosts assets. Basically remove all assets then start it from beginning. It will also bring one small issue to those DNS hostname could not be resolved.
If you have some hosts which DNS hostname could not be resolved by your DNS servers, they will not be scanned. Here is a screenshot for those DNS hostname could not be resolved.
Solution:
You will need to manually change them from DNS tracking to IP tracking.
Purge Assets Older than 90 Days
4.1 Manual Purge
The idea is to find all assets not scanned in last 90 days then purge them all.
4.2 Automatically Purge
From your Scans -> Option Profiles, enable the option to Close Vulnerabilities on Dead Hosts.
Delete Older / Obsolete Assets
- Create an asset group called “ToBeDeleted”
- Add all available IP’s in your subscription to it and save the AG
- Now go to Asset search
- Run an Asset search on the AG “ToBeDeleted”. Just select the AG and hit search. This returns a list of All IP’s in your subscription that has been scanned at-least once. (If it has been scanned at-least once, it isn’t a dead host). You may modify this search to suit your meaning of “Dead host”
- On this asset search result, select all IP’s and select “Launch a scan” (Don’t run the scan, just hit launch) option from the action menu
- In the Launch Vulnerability scan window, copy the target IP range
- Now go back to the Asset group tab and select to edit the Asset group you created called the “ToBeDeleted”
- In the Edit AG window, go to the IP’s tab, click Manually.
- In the manual entry IP window, paste the range you have copied and click “Remove”
- Now save your asset group again
- Delete or do whatever you want to do to the list of IP’s now in “ToBeDeleted”
