CHAPTER 5 SYSTEM SECURITY
This chapter discusses security features of your Efficient Networks router. A variety of
standard features as well as key enabled features provide the following categories of
security:
• Local Security
• Network Security
• Data Security
Local security entails limiting and controlling access to the router through any of the
user interfaces (serial, WAN and LAN). This is accomplished through User
Authentication.
Network security involves protection of the LAN from unauthorized access from
outside sources. The router can provide this protection through the use of
authentication protocols and filters. Filters are rules that selectively allow or deny
information to and from the local network. Filters can be classified as an input filter
that screens data coming into the local network, and an output filter that screens data
transferred from the LAN.
Network security also includes protection of the router and LAN-side clients as
intrusion methods can cause atrophy or outage of router and network services.
Data security is the protection of the actual data traffic itself through a variety of
encryption methods.
The sections that follow provide the procedures to employ these security features.
NOTE:
In the following procedures, it is assumed you are properly connected to the router
and the communication via the Command Line Interface or Web Management
Interface (WMI) has been established. If not, see “Installation and Setup” on page 3-1.
