In '96 or so, I went to my first Internet security conference. The attendees were a motley crew - junior programmers like myself, schoolteachers, old-school sysops, etc. Lots of us worked for companies that wanted unfettered access to this new Internet thing, but it had to be absolutely secure - and of course, it can't cost anything! There was hardly such thing as a network security professional then.
Things have changed a lot.
