Misconfigured Big Data apps are leaking data like sieves

Few of the MongoDBs I've come across have been secured properly

MongoDB is embedded in a number of applications. The users of these applications are incapable of reading manuals, so even when they are directed to instructions for securing the DB, they do nothing.

The people who write the software that controls the equipment that the users bought don't know anything about databases, they tend to be electrical and electronics engineers, who regard software as a necessary evil. They are also so insular, I'm not sure they really appreciate the need for security.

I regularly sort out MongoDB security (its not difficult), upgrade it from 32 to 64-bit (equipment engineers don't do this), and link it to Pentaho for reporting purposes. I must have explained how to do this upwards of 100 people, despite being "professionals", not one of them has been capable doing the same. From their point of view they just want kit that works. Sometimes I think that free Open Source software is the most expensive you can buy.
