Login and Password Security
Login and password security controls who can access the network. The network supervisor uses login and password security to
•Assign usernames to users of the network
•Require passwords
Additional password restrictions include a minimum password length, periodic password changes, unique passwords, and a number of grace logins after password expiration.
•Control the use of network resources by restricting where and when users can log in
•Detect intruders who attempt to access an account without the correct password
•Prevent unauthorized access to the server console
Server Security
Server security controls access to the server console. Access is controlled in three ways:
•Supervisor rights to the server are granted to give specific users rights to use a console.
•Directory rights are granted so that only specific users have access to the SYS:SYSTEM directory, where key server files are stored.
•Server utilities such as MONITOR and SECURE CONSOLE are used to prevent unauthorized access to the server console.
Additional Network Security in NetWare 4
NetWare 4 also provides NetWare Directory Services security to the network security it shares with NetWare 2 and 3.
NetWare Directory Services security controls what objects and properties the user is allowed to access.
