Description
Many organizations restrict the use of wireless technology in their network environment. However, most Mac computers have wireless capability built-in and simply turning it off may not meet the organization’s wireless technology restrictions. Components may need to be removed from Mac OS X to disable them from being turned on in System Preferences. Although wireless technology gives a network more flexibility with its users, it can also cause security vulnerabilities most may be unaware of. It is recommended wherever possible, wireless access is disabled for security reasons. IMPORTANT: Repeat these instructions every time a system update is installed.
