2.4.2 Relation Model of Security Management
1 Basic Glossary
Role, role group, and user are the basic glossaries used in security management of U31
system.
Role
A Role means the management authority of a user, defining a group of user management
authorities by specifying the operation permissions and management resources.
Operation permissions define which functional modules of U31 can be used by the role.
For example: for the log management module, it can be defined if the role is allowed to
query or maintain the logs. Management resources specify the sub-nets or specific NEs
under the sub-nets the role is able to operate. Operation permissions and management
resources are two aspects of a role. They are defined independently, but when a role is
used, the privileges of the role are the intersection of two aspects.
Role group
A role group is an aggregate of roles. Therefore, authorities of a role group are the
aggregate of those assigned to the roles. Via role group, it becomes very convenient to
assign authorities to the system administrator or sub-net administrators. This is because,
generally, an administrator's authorities are the aggregation of those assigned to
common users. To assign authorities of many roles to an administrator, use the role
group directly. Therefore, role group facilitates greatly assignment and management of
user authorities.
User
Users refer to the persons who are able to login and operate the U31 system. While
creating a user, the system administrator defines the authorities given to the user by
specifying his roles and role group; besides, by setting the user's department, he
determines which executive group the user belongs to. Overall management of users is
finally implemented.
2 Relational Model
The following figure describes the relationships among user, role group, role, and
operation permissions and management resources which are defined in the role.
NetNumenTM U31 (GU) Product Description
12 © 2013ZTE CORPORATION. All rights reserved. ZTE Confidential Proprietary
Figure 2-1 Security Management Relational Model
From the above figure, we can clearly come to the conclusion that:
A user's administration authorities are decided by his roles and role group.
A role group is a collection of one or more roles, so the authorities of a role group
are the aggregate of those assigned to the roles.
A role's authorities are defined by both operation permissions and management
resources.
2.4.3 Security Management Features
1 Security Event
U31 records security event logs such as authentication failed, user blocked, and user
prohibited in terms of user settings to help administrator aware of accounts status and
manage users’ accounts.
2 Security Alarm
If account is blocked, U31 generates corresponding alarm to remind administrator.
3 Login Time
NetNumenTM U31 (GU) Product Description
ZTE Confidential Proprietary © 2013 ZTE CORPORATION. All rights reserved. 13
System is able to set login time period, only during that period when users are available
to login.
4 User Account Rules Management
User may check and customize password length, password strategy, account lock rules,
expiration date of account and password and so on by security management module.
Customization satisfies security requirements at different levels. For example: inputting
wrong password for three times continuously, the user would be blocked to avoid illegal
login.
5 Login User Management
Forceful disconnection of user access
Supreme administrator can disconnect user’s access compulsively, hindering illegal
operation to ensure system security.
Set IPs supreme administrator can login
Since supreme administrator is able to do any operation with no restriction, IPs available
for a supreme administrator to login can be set in order to regulate supreme administrator.
Within IPs range set already, supreme administrator can login; otherwise, it cannot even
if the user name and password are correct.
Modify All Users’ Passwords
Supreme administrator can change all users’ passwords except administrator, with no
restriction of cryptogram rules. It can change all users’ passwords into an identical one.
This enables administrator to initiate all users’ passwords at one time and avoid other
users, especially illegal ones logging in, better guaranteeing system security.
Check user’ block status, unblock user
Administrator knows about blocking status of user at anytime, and can unblock them.
System enables user to unblock automatically, which can be set with automatic unblock
time in account block rules.
Interface Locked
If certain UE interface not be operated during a period of time, it would be locked
automatically. User has to re-login to avoid illegal users attack. User also can lock the UE
manually.
System administrator or current user can unlock the UE after entering the password.

2.4.4 Log Management
Log management is an effective tool which used by system administrator to trace the
running status of system, failure position, and user’s status of network. Common users
also could use it to review the history of operation and get to know the running status of
system.
NetNumenTM
U31 log includes system, security and operation logs.
Operation Log
Operation log records the information about user operation, such as log ID, operation
level, user name, operation name, host computer address, command function, detailed
information, operation result, failure reason, access mode, operation object, operation
start time, operation finish time, and associated log information.
Security Log
Security log records the users logging in information, including log ID, user name, host
computer address, log name, operation time, access mode, and detailed information.
System Log
System log records the mission completed situation of server. That includes log ID, level,
origination, log name, detail information, host computer address, operation start time,
operation end time, associate log information.
Log management includes the following log operations:
Log inquiry
User can set conditions of inquiry filtration, inquiry log content, and the result can be
saved and printed out.
Log backup
System can backup log information as files. The log could backup automatically or
manually before it achieves the threshold of storage capacity or days. And the threshold
is set by user.
Log deletion
User can delete log information, which is useless or had already been backed up.
2.5 Topology Management
U31 topology management provides users with vivid display of the relationship between
NEs and operable network topology views. The topology interface adopts the popular

ZTE Confidential Proprietary © 2013 ZTE CORPORATION. All rights reserved. 15
style: NE topology tree is on the left of the view and panoramic display of NE device on
the right. Users can define the map background and the latitude/longitude. The topology
functions are closely combined to each management module. Alarm information and
configuration can be viewed through the topology. Modules concerned with the
configuration, alarm, performance and diagnosis of each NE can be invoked. Topology
management provides with functions such as logical views, packet nodes, virtual NEs,
virtual links and so on. Users can manage the device and set the virtual NEs in packets,
which makes it easier for network display and analysis. The panoramic view can be
partially enlarged, searched and hierarchically displayed. Personalized interface setting
is available. Users can define their own interfaces, such as modifying icon type, color of

Topology management has the following functions:
1 Navigation tree
There forms the navigation tree when NE device is displayed in the form of a tree on the
interface. The correlation between topology views and the navigation tree nodes is
one-to-one correspondence. The navigation tree and topology views synchronize each
other. The navigation tree provides topology views with navigation and topology views
display the nodes specified by the navigation tree. The navigation tree nodes provide
functions related with these nodes, such as view of attributes, modification of NE
information and statistics of sub-nodes.
2 Topology display
Topology view displays a panorama of the whole network device’s topological structure
so that the NE device can be located on the topology view promptly. Users can lock the
location of the NE device icon so that it cannot be moved to other location until it is
unlocked. The node icon in the topology view shows the statistics of the NE device, such
as the number of NEs, links and packets and alarm information under this node.
3 Topology display control
U31 supports the following operation on topology views: panoramic translation, cascade
zoom in, cascade zoom out, recovery, panoramic display and local zoom in; browsing
forward, backward and location to any layer of the topology that has been browsed are
supported; specified NE device can be searched on the topology view; background map
of the topology view can be replaced; map of the world/China can be configured to realize
large-scale NE device management; even local map or map of the equipment room can
be configured to make the display of topology more humanized.
U31 will refresh the client after data synchronization is finished so as to ensure the
consistence of the topology data and configuration data. The NE device location set in
the topology will not be affected. Topology management module can be set in the layout
of topology view NE and deploy the display of NE according to the set layout. Layout
includes hierarchical layout, tree layout, radical layout, explosive layout and equidistance
layout.

operations (such as add MO, delete MO, modify attribute, alarm view, and so on.) and NE
modules to set users’ authorities, which can be accurate to certain operation in certain NE.
Users’ authorities check mechanism is set in server, which checks all operations user
made. Those operations that do not pass the check won’t be executed. User locked
feature is also provided. Invalid user could be locked and not allowed to log on the
system. Customized setting on user logon, user password, user expiration data, IP
address check, and so on is allowed, for example, users who fail logging on over 3 times

Server, Server and NE, up-level NMS interface and NMS to check the
communication status of links periodically. No alarm message of link between NE
and Server will be occurred.
2 Version check mechanism is adopted between Client and Server, Server and NE to
check their versions’ consistency. Inconsistent software version fails to connect them
normally. Meanwhile, language check will be performed between Client and Server.
If languages they use are different, they cannot be connected normally.
3 System controls and sets IP address restriction of Client and superior NMS by
accessing IP (port) of security management module, certain IP address will not be
allowed to log on, improving system security.
4 When services and process of Server go wrong, system generates alarm messages.
Employ SSL, SFTP, and etc. software; install firewall to prevent system from external
illegal attacks; adopt anti-virus software to scan virus.
