As a host-based intrusion detection procedure, This system focuses on the log data files on the computer exactly where you put in it. It monitors the checksum signatures of your log documents to detect achievable interference.
This technique performs entire log management in addition to presents SIEM. These are generally two capabilities that each one businesses have to have. Even so, the big processing capacity of the SolarWinds Device is greater than a little enterprise would wish.
