What you should know about Network Injector Appliance

Introduction

Network Injector Appliance is a network server for installation in an intra-switch segment at an Internet service provider.

An RCS agent can be injected in visited web pages or downloaded files by monitoring target connections.

Network Injector Appliance uses Network Injector - Network Appliance as an operating system and Appliance Control Center for control software.

NOTE: Network Injector Appliance is supplied installed and ready for use, complete with all the foreseen applications.

Main functions

Network Injector Appliance analyzes the target's traffic and, in the event set rules match, injects agents.

Network Injector Appliance communicates with RCS every 30 seconds to receive identification and infection rules and send status and logs.

Its Appliance Control Center control software can be set for remote access.

Network connections

Network Injector Appliance requires two network connections: one to tap the target's traffic and the other to inject agents and communicate with the RCS server.

Tip: after setup, Network Injector Appliance is independent. It can be left to run without further communication with the RCS server.

Service call: given special Network Injector Appliance features, this manual only provides essential connection indications, letting support service provide all those strategic aspects that are defined in the start-up and delivery phase.
