The Server Discovery function in IBM QRadar SIEM V7.5 uses the Asset Profile Database to discover various types of servers on a network. This database stores detailed information about the assets, including server types, configurations, and roles within the network. Here's how it works:

Asset Profile Database: This is the central repository that contains all the discovered asset information.

Discovery Process: During the discovery process, QRadar scans the network to identify servers and other devices, collecting information such as IP addresses, open ports, services, and operating systems.

Classification: The collected data is then analyzed and classified, updating the Asset Profile Database with the types of servers discovered.

Reference IBM QRadar SIEM documentation specifies the use of the Asset Profile Database for server discovery functionalities and provides details on configuring and managing asset profiles.
