The networked world of PCs and microcomputers ran into some predictable problems as these system lacked effective configuration control, compatibility, distributed management, security and information management. Firewalls needed to be built to separate networks and control access to sensitive data. Configuration control became a nightmare, and nobody was able to identify where critical information was being created, transmitted, used and stored.
In order to deal with these problems, many of the old solutions are once again the new ones — of course, with better marketing. Now we have data in the cloud, SaaS, big data and virtual machines. Of course, new problems are arising from these advances. Search “cloud security” and just see how many hits you get. Are these all really new problems, or simply the old problems returning with the evolution of technology?
