3 I. PURPOSE This standard defines the encryption requirements for data generated, processed, stored, transmitted, or used by the Virginia Commonwealth University. This document is intended to be used by VCU Data Stewards and Data Custodians to determine the need and applicability of encryption for the data managed by these individuals II. DEFINITIONS Category I Data - All data that require breach notifications in the event of improper release as governed by Federal, State, industry regulations, and / or other civil statutes. (Please refer to the Data Classification Standards for additional information) Centrally Managed Network Storage Devices Redundant electronic storage devices that are not native or directly connected to an individual s desktop, laptop, or other computing device. The network storage device is physically hosted and managed in data center(s) which has appropriate physical access protection, monitoring, and access management controls. Locally hosted servers and storage devices, regardless of its networking capability or redundancy, will not be considered as a centrally managed network storage device. Encryption - The process or the means of converting original data to an unintelligible form so it cannot be read by unauthorized users. Fixed Storage Device Internal storage media used by a computer to store files. In a computer system, fixed storage devices are usually the computer s internal hard drive(s). Data Custodian - An individual or organization in physical or logical possession of data for data stewards. Data custodians are responsible for protecting the data in their possession from unauthorized access, alteration, destruction, or usage and for providing and administering general controls, such as back-up and recovery systems. The data custodians are directly responsible for the physical and logical security of the systems that are under their control. Data Steward The data steward is a University director or equivalent position who oversees the capture, maintenance and dissemination of data for a particular operation. The data steward is responsible to ensure data quality, develop consistent data definitions, sensitivity classifications, determine data aliases, develop standard calculations and derivations, define security requirements, document all appropriate business rules and monitor data quality within the source system and/or data warehouse. The data steward is also responsible for communicating data protection requirements to the data custodian; defining requirements for access to the data. Laptop Computer A laptop computer is a battery or AC powered portable computing device that operates on traditional desktop operating systems such as Microsoft Windows and Mac OSX. University Owned Equipment Unless specified otherwise by the sponsoring funding source, any equipment purchased with funding allocated to the Virginia Commonwealth Page 3 of 7

Data custodians are responsible to adhere to the storage and transmission requirements delineated in this standard, and implement the encryption solution on IT systems used to store and transmit any applicable data. IV. STORAGE REQUIREMENTS The following section delineates the encryption requirements for the storage of electronic data generated, processed, stored, transmitted, or used by the Virginia Commonwealth University. A. Unless stored on University centrally managed or comparable network storage devices, all Category I data must be encrypted when stored in electronic format. B. All fixed storage devices on University owned laptop computers must be encrypted with the VCU enterprise encryption solution. V.
