A number of features make it easy to customize permissions in Windows NT. Introduced briefly in this section, these features are described in detail in the documentation for Windows NT Workstation and Windows NT Server. Become familiar with theses features so that you can plan and implement the security configuration you desire.
Caution No operating system can provide physical security for your computers. External media drives (floppy disk, CD-ROM, and so on) provide the physical means for anyone to bypass Windows NT and gain access to your files. For information on physical security, see the "Physical Security Considerations" section in "High-Level Security" later in this chapter.
