ITL Bulletin: Securing External Computers and Other Devices Used by Teleworkers [December 2007] [open pdf - 143KB]
"Many workers highly value the arrangements that they have with their employers to work from home or from other locations away from their organizations' facilities. This popular practice of teleworking, or telecommuting, benefits both the organizations and their staff members, who are able to read and send email, access Web sites, review and edit documents, and perform many other tasks from remote sites. These teleworkers use devices such as desktop and laptop computers, personal digital assistants (PDAs), and cell phones to access their organization's nonpublic computing resources and to conduct business from them when they are at home or traveling. For many years, teleworkers were limited in their activities because their dial-up modems, which were the primary communications mechanism for remote access, operated at slow speeds. Today high-speed Internet connectivity and broadband communications provide fast data transfer rates, greatly expanding the productive use of remote access capabilities by teleworkers. But with increasing intruder attacks and other threats in today's computing environment, teleworkers and their organizations are challenged to plan carefully to protect the security of telework devices, networks, and information resources."
