The Lake County Sheriff's Dept was hacked by people who downloaded about 40gb of files from the Sheriff's servers. That is not a good indicator of their knowledge about computer security. As a former corporate internal auditor and certified information systems auditor, my observation is most law enforcement departments (Police & Sheriff) are still stuck in focusing on physical crimes using kinesthetic staff, and not focusing on intellectual crimes requiring people with technical degrees. This is the result.
I would recommend the Sheriff create an anti-hacking & IT Controls committee of volunteers, much like the County Board and School Board have committees, and have them review both internal IT practices and ability to act when local IT crimes are reported.
I tried contacting the Sheriff's public information officer, but no one answered either phone.
However, the articles below give a good overview of the incident.
