Description

[0001] The present invention relates to a POS terminal,
The present invention relates to a force terminal approval system, and more particularly, to an approval system of a force terminal based on a network separation.
As shown in FIG. 1, a large-sized store and a special organization store (such as NACF Hanaro Mart) have an internal network in which an integrated approval server 200 and a force terminal 400 are connected in a VPN-based internal closed network.
However, due to the nature of distribution stores, there is a communication route from the distribution store directly to the outside van to maintain the approval speed and the 24 hour / 365 day disarmament system.
In the credit card approval process, the card approval from the POS terminal 400 is a first method in which the card approval is based on the integrated approval server 200, which is an integrated van of the main system of the main store, There is a second method in which the POS terminal 400 in the distribution store directly accepts approval for each van through the external network when the approval fails. The priorities of the first scheme and the second scheme may be different depending on the store situation.
On the other hand, the separation of networks according to the amendment of information and communication network law will be mandatory. As a personal information handler who has a high access right to a personal information processing system is hacked and a large amount of personal information leakage accidents occurs, it has become necessary as an enhanced personal information protection measure to prevent an outflow accident. In the 「Information Communication Network Promotion and Information Protection Act」, the requirement to separate networks was newly established. It is intended to isolate the intrusion path from the outside by separating the Internet and the business network of the personal information handler having high access authority.
Therefore, according to the principle of separation of internal and external networks, the direct approval connection through the internet network to the external van (VAN) at the distribution store will be blocked and the approval method will be changed to the approval method through the head office integrated van.
However, in such a case, there is a problem that when a failure occurs on the approval route through the integration approval server 200 of the main store of the retail store, the card can not be directly approved at the retail store in the field.

As the reliance on the Internet increases, cyber attacks are becoming more and more common in various forms such as hacking, malicious code, and spreading malicious programs, and are damaging to society and the nation from information leakage, system downturn, site and network paralysis to terrorism.
 However, in the case of business sites (retail establishments) that are subject to network separation, most of them are violating the principle of network separation because they communicate directly with VAN through the Internet for the purpose of improving credit card approval rate and reducing communication cost. Furthermore, the connection between the PC and the POS terminal 400 in the internal network and the external Internet is exposed on the same Ethernet network and is exposed to hacking attempts from the outside. When a problem occurs in a wired network in connection of a VAN company through an external Internet network, an unacceptable situation may occur.
Therefore, the network separation technology has been inevitably required as a means to protect important information of the country and industry by blocking the cyber attack which is continuously increasing. The government has started to separate the network of national institutions since 2008, Starting with the separation of networks of specified national infrastructures and public institutions, it promotes the network separation policy of the national infrastructure and public institutions designated by the Information-based Infrastructure Protection Act and separates the Internet, business network and control network, To protect the national system.
Network separation techniques are classified physically and logically, and national and public organizations apply a lot of physical network separation. Physical network separation is a technology that separates the external and internal networks separately, which is excellent in security stability, but has high network construction and maintenance costs. On the other hand, logical network separation that separates external and internal networks using virtualization technology is excellent in terms of efficiency but has a low security reliability. Therefore, it is necessary to develop information protection technology that can safely protect internal important information from intelligent cyber attacks.
