Sensitive Data Storage Best Practices
As an employee of CSU East Bay, you are responsible for all university data that is sent, stored, or shared on all personal or university-owned devices that you use. Part of this responsibility includes choosing appropriate technology to manage and store the data, some of which may be confidential or restricted. We have multiple options for data storage — from University servers to cloud-based services — but not all options are appropriate for all types of data. To help you choose the proper solutions for your university data, we've developed a matrix that outlines what can be stored where.
Sensitive Data Storage Classification
Information in the matrix below applies only to CSU East Bay enterprise versions of the services. CSUEB Data must never be stored in a consumer personal Gmail account e.g., mymail@gmail.com.
