2 I. PURPOSE The Data Handling and Storage Standard documents the handling, storage and disposal of sensitive data within the VCU School of Medicine. II. III. POLICY Organizational sensitive data consists of data that are vital to the organization. These data are owned by the VCU and / or VCUHS, and it is up to the individuals who are authorized to access the data to ensure the confidentiality, integrity and security of these organizational data. This document denotes the standards in the handling and storage of such data. DEFINITIONS Authorized User An individual who has been granted access to specific data in order to perform his / her assigned duties in the VCU School of Medicine. Users include, but are not limited to faculty and staff members, trainees, students, vendors, volunteers, contractors, or other affiliates of VCU or VCUHS. Confidential and Protected Data Confidential and Protected data are considered the most sensitive, and must be protected with the highest security standards. These data are protected specifically by federal or state law and regulations (e.g. HIPAA, FERPA.) Loss of confidential and protected data can result in long term loss of funding, ranking and reputation for the school, as well as possible legal actions against the University, School, or the data owner. Confidential and protected data are a subset of sensitive data; therefore, all confidential and protected data are also classified as sensitive. Examples include student or employee SSN, date of birth, Electronic Protected Health Information (EPHI), and student grades. Refer to the "School of Medicine Data Classification Guidelines" for authoritative definitions. Data Owner The Data Owner is the VCU or VCUHS employee responsible for the policy and practice decisions regarding data, and is responsible for evaluating and classifying sensitivity of the data; defining protection requirements for the data based on the sensitivity of the data, any legal or regulatory requirements, and business needs; communicating data protection requirements to the System Owner; defining requirements for access to the data. External Account or other user accounts that do not belong to VCU or VCUHS. These accounts are either managed individually or collectively by organizations that are not a part of, but may be associated or affiliated with VCU or VCUHS. IT System - An IT System is a combination of people, hardware (computer workstation, mobile device, removable storage media, server), software, Data Handling and Storage Page 2

3 communication devices, network and data resources that processes (can be storing, retrieving, transforming information) data and information for a specific purpose. Local Storage Device An electronic storage device that is native or can be directly connected to an individual s laptop, desktop, or other computing device. A local storage device can include, but are not limited to hard disks, USB Flash drives, CD / DVDs, audio players, and portable hard drives. Network Storage Device An electronic storage device that is not native or directly connected to an individual s desktop, laptop or other computing device. Rather, the network storage device is a storage device hosted and managed in a data center which has appropriate physical access protection, monitoring, and access management controls to ensure that only authorized users can access data. Non-sensitive Business Data - Non-sensitive business data are non-personal data that are not necessarily proprietary to an institution. The protection of these data are neither regulated nor controlled by law or contractual obligations, as the protection of the data is at the discretion of the data owner. If lost or illegitimately modified, these data will generate no negative impacts to individual business units or the institution as a whole. Refer to the "School of Medicine Data Classification Guidelines" for authoritative definitions. Offsite Storage - The process of storing copies of vital records in a facility that is physically remote from the primary site. To qualify as an offsite, the facility should be geographically separated and distinct from the primary site and offer physical access protection, monitoring, and access management controls to ensure that only authorized users can access data. Principle of Least Privilege This principle requires that each user in a system be granted the most restrictive set of privileges (or lowest clearance) needed for the performance of authorized tasks. Sensitive Data Data that are proprietary to an institution, where if lost or illegitimately modified, can cause negative impact to the individual units or the institution as a whole. Examples include employee performance evaluations, faculty salary or contract information, and proprietary research data. System Owner A VCU or VCUHS employee who is responsible to authorize or deny access to IT system to system users. The system owners are directly responsible for the physical and logical security of the computer workstations that are under their control. IV. RESPONSIBILITIES Data Handling and Storage Page 3

4 A. Data owners must determine the classification of their data and communicate data protection requirements to the System Owner to ensure that their data is protected in a manner appropriate to its classification. B. Data Owners are responsible for the integrity of the data and therefore have responsibility to review lists of users with access to their data and to approve any major changes or modifications. C. The authorized users of sensitive data are responsible for assuring that their use of data is in compliance with this standard. D.
