Unknown Attack (4203020)

Jump to solution

Hi.

After new signature set version 9.8.33.6deployment, I can see several attack name "Unknown".Such attack log has no description, no matching criteria:

2018-10-31 16_22_07-McAfee Network Security Manager - ipsmgmt.ug.cz.png2018-10-31 16_23_46-McAfee Network Security Manager - ipsmgmt.ug.cz.png

Seems some signature issue. Can anyone confirm ?

Yes. cache flushed. No change. No Attack Name, only some internal ID 4203020

Update: After delete of policy cache, the old events are still marked as Unknown but all new events are identified OK.

Ok so you are now seeing the appropriate name for new alerts coming in?

Old attacks won't change to the correct name, just the new ones.
