9.8.2 Procedure for Securing and Accessing Each Data/System Classification

I.  Purpose

This document establishes the minimum controls to protect against theft, compromise, and inappropriate use based upon data classification. Procedures for classifying data and the data categories are provided in the 9.8.1 Data Classification Procedure.

II.  Coverage/Applicability

Data resources are the discrete assets that store, process, transmit, or receive data. The data resources covered by this procedure include:

Data Resource Type Description
Non-Electronic Media Printed, hard-copy versions of information.
Electronic Media  
  University owned, maintained, or contracted servers Systems that the University has purchased, maintains, or has entered into a contract that provides services such as but not limited to: file sharing, web services, database services, print services.
  University owned, maintained, or   contracted workstations Systems that the University has purchased, maintains, or has entered into a contract that do not act as servers and are not considered mobile. Examples include but are not limited to: Dell Optiplex, Apple Mac Pro, HP Compaq
  Personally owned workstations Systems that the University has not purchased, does not maintain, or has not entered into a contract that do not act as servers and are not mobile. Example include but are not limited to: Dell Optiplex, Apple Mac Pro, HP Compaq
  University owned or maintained   laptop computers

Systems that the University has purchased, maintains, or has entered into a contract that do not act as servers and are laptops.   Examples include but are not limited to: Dell Inspiron, Apple MacBook, Lenovo ThinkPad.

  Personally owned laptop computers Systems that the University has not purchased, does not maintain, or has not entered into a contract that do not act as servers and are laptops. Examples include but are not limited to: Dell Inspiron, Apple MacBook, Lenovo ThinkPad.
  University owned or maintained mobile devices

Systems that the University has purchased, maintains, or has entered into a contract that do not act as servers, are not laptops, and are mobile. Examples include: Apple iPads, Samsung Galaxy, Blackberry PlayBook, Apple iPhones, Motorola Droid, BlackBerry smartphone.

  Personally owned mobile devices Systems that the University has not purchased, does not maintain, or has not entered into a contract that do not act as servers, are not laptops, and are mobile. Examples include but are not limited to: Apple iPad, Samsung Galaxy, Apple iPhone, Motorola Droid, BlackBerry smartphone.

  University owned, maintained, or contracted printers, scanners/faxes, multi-function devices, and electronic surveillance devices

 

 Systems that the University has purchased, maintains, or has entered into a contract that performs printing,scanning, faxing, or electronic surveillance.

 

   Personally owned, maintained, or contracted printers, scanners/faxes, and multi-function devices, and electronic surveillance devices

 

Systems that the University has purchased, maintains, or has entered into a contract that performs printing, scanning, faxing, or electronic surveillance.

 

III.  Responsibility

Procedures addressing the minimum or baseline controls for securing data that is stored, processed, transmitted, or received by each data resource type are described below. The highest level of data classification being stored, processed, transmitted, or received by the resource determines the minimum level of controls required for the resource. For example, if a server or workstation is storing, processing, transmitting, or receiving data that is classified as Highly Restricted and it is also storing, processing, transmitting, or receiving data that classified as Restricted, the controls for Highly Restricted are required.

Individuals (as defined in Procedures 9.8.3 and 9.8.7) have varying responsibilities under this procedure. Data Stewards in conjunction with Unit Security Liaisons, Data Custodians, Functional Owners, Security Administrators, and System Administrators are responsible for implementing and administering these minimum controls. Data Stewards in conjunction with Unit Security Liaisons, Data Custodians, Functional Owners, Security Administrators, and System Administrators may develop requirements in addition to these minimum controls dependent upon regulatory, legal, or contractual requirements. Data users are also responsible for adhering to the established minimum controls. If you do not meet the minimum controls for the type of data you are using you are prohibited from using the data in that media format. For assistance, contact your Unit Security Liaison.

Security Review for Purchases or Development of Systems Handling Highly Restricted Data

Departments evaluating the purchase or development of a data resource that would be storing, processing, transmitting, or receiving Highly Restricted data, must contact the Data Stewardship Committee prior to development or undertaking the purchasing process.

IV.  Non-Compliance and Exceptions

Non-compliance with these standards will result in revocation of system or network access.

If any of the controls contained within this document cannot be met on data resources storing, processing, transmitting, or receiving Highly Restricted, Restricted, or Unrestricted data, an Exception Request must be initiated that includes reporting the non-compliance to the Data Stewardship Council via the Information Security Officer.
