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 employ 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 Internet Key Exchange (IKE) 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 Virtual Private Network (VPN). For IPsec transmissions, the following conditions are necessary: - A computer that can communicate using IPsec is connected to the network. - Your Brother machine is configured for IPsec communication. - The computer connected to your Brother machine is configured for IPsec connections. • IPsec settings The settings that are necessary for connections using IPsec. These settings can be configured using Web Based Management. To configure the IPsec settings, you must use the browser on a computer that is connected to the network.

: MFC-J995DW

IPsec (Internet Protocol Security) is a security protocol that uses an optional Internet Protocol function to prevent

data 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 employ 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 Internet Key Exchange (IKE) 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

Virtual Private Network (VPN).

For IPsec transmissions, the following conditions are necessary:

A computer that can communicate using IPsec is connected to the network.

Your Brother machine is configured for IPsec communication.

The computer connected to your Brother machine is configured for IPsec connections.

•

IPsec settings

The settings that are necessary for connections using IPsec. These settings can be configured using Web

Based Management.

To configure the IPsec settings, you must use the browser on a computer that is connected to the network.
