@Remote uses the following methods
to ensure security in communications
| - |
Remote Communication Gate (RC Gate) obtains
ISO 15408 certification (Common Criteria) that is the international
standard to evaluate IT security of a product or system (RC Gate
for Japan is not applied). |
|
| - |
Communications with the Data Center pass
through the security network configured by the customer. |
|
| - |
Communications between RC Gate and Ricoh,
and between devices and RC Gate, use the SSL system (*).
* SSL (Secure Socket Layer), a
protocol with added data encryption, is widely used in applications
such as Internet shopping. |
|
| - |
The devices, RC Gate and Ricoh systems,
each have their own electronic certificates.
These certificates are exchanged before every communication transaction,
authenticating the counterpart for each party before using the public
key encryption for communications, which protects data from improper
acquisition through spoofing. The RC Gate and each device has its
own, specific certificate. |
|
| - |
The RC Gate regularly polls the Ricoh Group
side to report its operational status, and to verify the instruction
sent by the Data Center. When the devices are accessed from the Data
Center for purposes such as firmware updates, communication is only
enabled after mutual cross-checking when the RC Gate polls the Data
Center at regular intervals. Therefore, the Ricoh Group will never
initiate an RC Gate action from the Internet.
Also, the RC Gate makes automatic reports at the following times.
(These are not communications at polling times) |
|
| - |
Meter/counter reporting (automatic meter/counter
reading), automatic notification of a breakdown, alarm information,
manual calls and toner calls. |
 |
| - |
@Remote sends information on services provided, such as maintenance of managed devices, and RC Gate (the @Remote dedicated device) registration information, to the Data Center. The RC Gate never acquires any data that has been scanned or output by the devices. |
