Network Security
Security is vital in maintaining a productive network environment. NetWare
provides an extensive security system to protect the data on the network.
Network Security Levels
NetWare 2, 3, and 4 have three levels of security that can be used separately
or in various combinations.
File System Security
File system security consists of rights security and attributes security.
Rights security controls what the user is allowed to access in and do to
network directories and files. Rights can be granted at either the directory or
file level.
Rights security is administered by granting trustee assignments to objects
and by acquiring effective rights through inheritance and security
equivalence.
Attribute security assigns various characteristics to individual directories
and files. Directory and file attributes have priority over rights security and
can prevent tasks that effective rights would allow. Attributes can be used to
prevent users from
• Deleting a file or directory
• Copying a file
• Viewing a file or directory
• Modifying a file
• Creating a new file
Attributes can also be used to
• Mark a file for single-user or multiple-user access
• Mark a file as modified so that a backup program can select it and leave
unmodified files alone
• Protect a file from corruption by ensuring that either all changes are made or no
