- PROTEC NET Overview
-
-
-
-
- PROTEC NET for Novell NetWare extends security
- from the file server down to the workstation. It
- is designed to protect workstations from
- unauthorized access and to limit or prohibit
- access to sensitive information located on the
- workstation. Specifically, security may be
- configured to prevent accidental or malicious
- deletion, software and information piracy and
- unauthorized manipulation of data in memory or on
- disk. At the same time, it tracks DOS and PROTEC
- NET events providing detailed audit reports of
- workstation activity.
-
- To provide security while minimizing
- administration overhead, PROTEC NET integrates
- closely with Novell NetWare and makes use of its
- groups, users and passwords. Further, PROTEC NET
- deploys all workstation security centrally from
- the workstation's Security Server. A Security
- Server is a name to identify a file server that
- contains all programs and data needed by PROTEC
- NET to configure and install workstation security.
-
- Supervisors set access rights for workstations
- within PROTEC NET using NetWare groups. Just like
- Novell NetWare, users may be assigned to multiple
- groups and any modifications to a group affect
- only its users, making modification and
- installation of security elementary.
-
- Once installed onto a workstation, a user can only
- access this PROTEC NET workstation and any
- available servers through PROTEC NET's Login
- screen. Users are required to sign onto a PROTEC
- NET workstation using their Novell NetWare user
- name and password. Once verified as an authorized
- NetWare user, PROTEC NET allows access to the
- workstation and its resources if granted to do
- so.Permissions.
-
- ============================================
- Users, Groups and Group Access Permissions
- ============================================
-
- There are two types of users, supervisors and
- users. A supervisor is the NetWare supervisor or
- a user with supervisor security "equivalence" as
- defined through Novell NetWare and is allowed
- access to any PROTEC NET workstation. Supervisors
- are responsible for configuring workstation
- security. Users, groups and passwords are not
- managed by PROTEC NET. Instead, supervisors must
- install users, groups and passwords through
- NetWare's Syscon utility.
-
- Any user who can access a PROTEC NET workstation
- must be installed as a NetWare user of a Security
- Server. The server containing user workstation
- privileges is designated as a user's Primary
- Server. PROTEC NET uses the Primary Server to
- retrieve a user's access rights during signon.
- Each user, excluding a supervisor, must be
- assigned a Primary Server to gain access to a
- PROTEC NET workstation. If a user is assigned a
- Primary Server but does not belong to a NetWare
- group on the server, he is allowed full access to
- the workstation. Refer to Maintaining a Secure
- System for information on protecting the Security
- Server.
-
- Once established as NetWare user, user security
- can be defined through the Security program,
- PSECURE.EXE. User security for workstations is
- organized through NetWare groups. Users must be
- assigned to a Novell NetWare group to limit access
- to a workstation. These access rights are called
- Group Access Permissions. If needed, multiple
- groups may be created within NetWare to define
- workstation security. For information on
- configuring Group Access Permissions, refer to
- User Security and How Permissions are Evaluated.
-
- When installed, PROTEC NET automatically installs
- the group PROTEC_GROUP and the user PROTEC_USER
- into the Security Server. All users must belong to
- the PROTEC_GROUP so that PROTEC NET may record
- user activity and update user and workstation
- security properly. The PROTEC_USER assists PROTEC
- NET with password synchronization between multiple
- servers. Both the PROTEC_USER and the
- PROTEC_GROUP should not be deleted. If either has
- been removed, refer to PRIMSRVR.EXE for
- instructions on reinstallation.
-
- =========================================
- Security Servers and Password Management
- =========================================
-
- A Security Server is a file server that contains
- all programs, data and login script modifications
- needed by PROTEC NET to configure and install
- workstation security. A Security Server should
- not infer that the server is designated for PROTEC
- NET use only. PROTEC NET must be installed on
- each server if its users are signing onto a PROTEC
- NET workstation.
-
- Each Security Server is responsible for recording
- every workstations' network address and provides
- programs to administer workstation security
- centrally. PROTEC NET uses NetWare's System Login
- Script to aid in this task. PROTEC NET inserts
- its administrative programs, the NET Script
- programs, into the System Login script. Each time
- a user logs onto the system, the NET Script
- programs ensure the workstation resources have
- been recorded, and install or update security as
- scheduled. As defined by NetWare, only
- supervisors may modify the System Login Script.
- For information on modifying the System Login
- Script modifications, refer to Server
- Installation.
-
-
- Further, PROTEC NET supplies its set of Login
- programs, LOGIN.EXE, LOGOUT.EXE and MAP.EXE.
- These programs are Novell NetWare compatible but
- have been created to be PROTEC NET "aware."
- Specifically, LOGIN.EXE interprets additional
- login script commands that minimize password
- management between file servers. Passwords may be
- synchronized from one file server to another and
- passed automatically between servers using its
- synchronization, single signon and attach
- commands. PROTEC NET's single signon command
- allows users to attach to other servers without
- having to specify a user's name and password
- within a user login script.
-
- Other PROTEC NET script commands are provided to
- assist in security setup. Refer to Login Commands
- for Novell NetWare for more information.
-
- ==================
- How Security Works
- ==================
-
- This section assumes that a Security Server has
- been established and the NetWare System Login
- Script has been modified properly to include
- PROTEC NET Script programs. When a user signs
- onto the Security Server for the first time,
- PROTEC NET records the workstation's network
- address and creates a directory tree of resources.
- Once the network address is recorded, the
- supervisor may schedule PROTEC NET to be installed
- onto the workstation using the Security program
- PSECURE.EXE.
-
- Once installed onto a workstation, a user must log
- onto PROTEC NET before gaining access to the
- workstation. This workstation may be referred to
- as a PROTEC NET workstation. He is required to
- specify his Primary Server and to enter his user
- name and password associated with it. If a user
- has not been assigned a Primary Server, he may not
- access any PROTEC NET workstation.
-
- A PROTEC NET workstation remains as an Open system
- until a supervisor restricts access. This design
- intends to make workstation installation
- transparent to the user while security is
- configured in the background by a supervisor.
- Since the system is Open, you may want to review
- information provided in Maintaining a Secure
- System.
-
- Once a user is verified as an authorized user,
- PROTEC NET configures permissions for a user and
- executes NetWare's System and user login scripts.
- This means that each NET Script program runs and
- performs the necessary security functions
- scheduled by a supervisor each time the user logs
- onto the workstation, thereby maintaining a secure
- workstation. If a user logs off the network using
- LOGOFF.EXE, workstation permissions remain in
- effect until a new user signs onto the PROTEC NET
- Login screen or reboots the system.
