Here are the two files that store everything about the KinetEco database that we've been working with. These are the data and the log files. Because I can access the actual files outside of SQL Server, these files are vulnerable to malicious attacks and alterations. And that's exactly what I've just done. I've gone in and changed some of the data outside of the authentication protections that SQL Server would normally enforce. Now, I'm not going to go into detail about exactly what I did or how I did it because, well, frankly, it's just not a very honest thing to know how to do, but it's exactly the kind of hack that could affect your own database if someone malicious were to gain access.
