There was a time when computer programmers on IBM’s midrange platform joked about “security through obscurity.” The data and programs were safe mainly because so few people knew how to get into them. Even if a hacker found a way to connect, the platform architecture was unique and the boxes were priced out of reach for the hacker demographic, preventing experimentation.
The low-hanging fruit for the hackers was on a different platform, machines running Microsoft’s Windows. They knew those machines well enough.
And so programmers didn’t worry as much about security on the IBM midrange machines as the programmers on other, better-known machines did. The lack of public knowledge served for purposes of security and virus prevention.
There was a downside to obscurity though. The midrange programmers watched as sales of their machine stagnated and companies switched to the more popular Windows based systems in spite of security concerns. The job market for midrange programmers shrank and wages fell.
Obscurity turned out to be just another word for unpopular.
