There are a few absolutes when it comes to school. First, lunches will always be terrible. Second, your locker will be too small to fit your oversized textbooks. Finally, there's a high likelihood that some of your student data will be stored in the cloud. This student data includes demographic information, test results, transcripts, email exchanges, grades, attendance history, contact information and more. It's a sensitive mix of detail that, if exposed, could prove damaging to the affected students and the educational institution. According to privacyrights.org, more than 1.8 ... (more)
