It has been more than ten years since the security industry combined SIM and SEM into the industry standard today known as SIEM, and a wide gap still looms between this pragmatic approach to IT security across distributed systems and those of its mainframe counterparts. This is due, in part, to Windows/UNIX and mainframes having matured side by side since the 1980s, but in essentially separate universes.
Each platform employs its own terminology, coding languages, user interfaces, human resources, and IT infrastructures. This siloed friction between the “two worlds of IT” has resulted in a lack of security cohesion across both platforms, and has weakened what must be a unified front against the growing threat of cybercrime.
