Network Security Issues

This section describes a strategy to ensure the security of an intranet that is connected to DEFINITY ECS R7 or later systems.

Overview

The TCP/IP connectivity available with Release 7 and later of DEFINITY ECS makes it possible to connect one or more DEFINITY ECS systems in a network that includes connections to a company’s existing data network (LAN or intranet). This integration of networks introduces the possibility of unauthorized access — to the DEFINITY network through the LAN/intranet and to the LAN/intranet through the DEFINITY network.

Security concerns

Security can mean many different things. The strategy described here focuses on three key concerns from a customer perspective:

1How can a customer network be protected from unauthorized outside access through a DEFINITY ECS? That is, how can a hacker be prevented from dialing into a DEFINITY ECS and getting on the customer LAN?

2How can a customer network be protected from unauthorized access by Lucent services personnel?

3How can a DEFINITY ECS be protected from unauthorized access through the customer LAN?

Security solutions

The first and most important line of defense in any security strategy is access control. Damage to the network or theft of proprietary information by hackers can be prevented by completely denying access to unauthorized users.

Access control can be provided by three means:

•network topology

•network administration

•authentication
