Questions and Answers

Q1. Is data that is

sent out over the

Internet secure?

A. Yes – because it is transmitted in SSL protocol, after both ends verify

each other’s identity, and only to the address specified at setup. Also, for

further security, the data itself is encrypted (AES (Advanced

Encryption Standard)256bits).

Communication between Remote Communication Gate and the

Communication Server uses the form initiated by the Remote

Communication Gate.

* Communication is never initiated from the Communication Server.

Q2.

What kind of

data is received from

the Communication

Server?

A. When the Communication Server requires device information it sends a

request (status sense) for it.

Also, if a device encounters problems, the Communication Gate sends

the latest firmware to help it recover.

Q3. How is the

firewall passed from

the Communication

Server?

A. Initiation is from the Remote Communication Gate:

To go through the firewall, the Communication Server must send

necessary information in reply to the signals sent regularly from the

Remote Communication Gate (frequency specified at setup).

* Communication does not come from the Communication Server.

Q4. Can viruses enter

the user network

when communicating

over the Internet?

A. No - because communication occurs only within the limits of Remote

Communication Gate and the Communication Server.

Also, the data (virus checks are carried out before sending) is sent in

SSL protocol after mutual authentication.

Q5. What about

traffic on the user

network and its

communication

timing?

A. Traffic size and its communication timing will differ depending on the

communication data type.

Please refer to Appendix 5 for the detailed traffic size and its

communication timing.
