QRadar receives an event. How does the asset profiler examine the event payload for identity information?
- A. If an asset update has an IP address that matches an existing asset, but the other identity information does not match, the system uses other information to rule out a false-positive match before a new asset is created.
- B. If the identity information includes a port number, a NetBIOS hostname, or a DNS hostname that is already associated with an asset in the asset database, that asset is merged with previous entry.
- C. If the only available identity information is an IP address, the system reconciles the update to the existing asset that has the same IP address. IBM QRadar uses identity information in an event payload to determine whether to create a new asset or update an existing asset. 1. QRadar receives the event. The asset profiler examines the event payload for identity information. 2. If the identity information includes a MAC address, a NetBIOS host name, or a DNS host name that are already associated with an asset in the asset database, then that asset is updated with any new information. 3. If the only available identity information is an IP address, the system reconciles the update to the existing asset that has the same IP address. 4. If an asset update has an IP address that matches an existing asset but the other identity information does not match, the system uses other information to rule out a false-positive match before the existing asset is updated. 5. If the identity information does not match an existing asset in the database, then a new asset is created based on the information in the event payload. (correct)
- D. If the identity information matches an existing asset in the database, then a new asset is created based on the information in the even
