UTM/SIEM/NGFW tools

摘要

UTMs are defined clas-sically as combinations of anti-virus, firewall and IDS (or some similar combination, depending on which vendor you listen to). SIEMs classically emerged from a marriage of SIM (secu-rity information manager) and SEM (security event manager). So much for classical defini-tions. Today we see supersets of each and crossovers between the two, which is where we believe this genre is headed.
