Can anyone can shed some light to understand Asset tags and Asset groups along with its individual usage?
I am confused in using it.Wanna know the differences if they have.
They have very similar uses. When you create an Asset Group it will also create a TAG. Qualys is moving to do everything with TAGs but on occasion I use groups. Right now I have MAP scans that are not recommended for normal use as an example and you use groups for that; map scans don't use TAGS.
My recommendation would be to to read up on cpepper article on Tag all the things or something like that to give you an idea of the power of TAGS. They also work across modules and are used extensively for the dashboards in Qualys.
Unless you really need to control scanners used as part of a scan I would recommend to try and use TAGs first. If you have more questions on how I would post the use case here and you should get more specific recommendations. Also you might want to consult the documentation on Groups .vs. Tags which seems to be what you are after.
In addition to what has been suggested, this folder has a bunch of videos on asset groups and tags - how and when to use them - Video Library: AssetView and Threat Protection | Qualys, Inc.
