Introduction

Overview

IPsec (Internet Protocol Security) is a security protocol that uses an optional Internet Protocol function to
prevent manipulation and ensure the confidentiality of data transmitted as IP packets. IPsec encrypts data
carried over the network, such as print data sent from computers to a printer. Because the data is encrypted
at the network layer, applications that use a higher-level protocol use IPsec even if the user is not aware of
its use.
IPsec supports the following functions:
 IPsec transmissions
According to the IPsec setting conditions, the network-connected computer sends data to and receives
data from the specified device using IPsec. When the devices start communicating using IPsec, keys are
exchanged using IKE (Internet Key Exchange) first, and then the encrypted data is transmitted using the
keys.
In addition, IPsec has two operation modes: the Transport mode and Tunnel mode. The Transport mode
is used mainly for communication between devices and the Tunnel mode is used in environments such as
a VPN (Virtual Private Network).
Note
• For IPsec transmissions, the following conditions are necessary:
• A computer that can communicate using IPsec is connected to the network.
• The printer or MFC is configured for IPsec communication.
• The computer connected to the printer or MFC is configured for IPsec connections.
• IPsec does not support broadcast or multicast communication.
 IPsec settings
The settings that are necessary for connections using IPsec. These settings can be configured using Web
Based Management. (See Configuration using Web Based Management (web browser) uu page 2.)
Note
To configure the IPsec settings, a computer that can operate the browser must be connected to the
network.
