Many people are disconcerted at recent, diverse information leaks from insurance companies, public
offices, and education sources. Besides, it is much surprising that personal information on many Koreans can be read in Chinese
websites. We are worried about this series of facts, if it may suggest overall
reexamination on personal information system having been managed by the
resident register number
By the way, why do information
leakage incidents continue to happen even in the organization adopting Network
Separation solution? How far is the effective range of information leak
control by Network Separation? Let’s look into the Network Separation based on
Document Centralization Solution if it can be a new alternative of the existing
Network Separation.
Existing Network
Separation Solution?
In the meantime, Korean government has positively
recommended Network Separation to public offices, financial institutions, and
personal information treatment companies to prevent leaks of national secrets
and important data. At first, only physical Network Separation was permitted, and
later a server based computing (SBC) was additionally permitted, and now a virtual
environment-providing type in PC-so called a CBC type- has been permitted.
However, it seems that many public
agencies and companies are reluctant to adopt Network
Separation. The reasons can be summarized as issues
of cost and stability. Then, what is the creative, innovative Network
Separation method which reduces cost and secures stability?
Suggestion of a
new Network Separation Solution
Network Separation function included in
ClouDoc premises document centralization environment. Task document does not
exist in document centralized environment. One PC stays
in an intranet mode or internet mode in a certain moment. As this type does not need to use a non-standard type under the window
operating system to maintain intranet and internet environment, it provide
stable work environment for a user.

You don’t have to
change Network configuration, to prevent information leakage.
The current Network Separation
type adopted by most organizations require physical change of network
configuration. The
reason would be to prevent information leakage from PCs with no basic installation
to internet. On the other hand, ClouDoc NetworkLock
function allows construct safe Network Separation environment only by minimum
HW or SW additions, leaving the physical network configuration as it is.

Safe data
exchange even without additional data exchange solution between networks
Network Separation environment
being currently adopted includes data exchange system between networks as well. Intranet and internet are
physically separated, and data exchange system between networks using an
expensive device is provided. ClouDoc resolves this
matter in Software. With an export disk based on the internal approval
procedure, safe data exchange environment between intranet and internet is
provided.

Complete
interruption of information leakage by hacking
The most critical purpose of
NetworkLock is to interrupt internal information leakage by a malignant code. As ClouDoc permits access to
internal data only in the intranet mode and at the same time completely
interrupts internet connection, perfect information
leak prevention environment is provided. Besides, in the internet mode
the access to the internal system by an external malignant code is completely
controlled.

Information leak
prevention by human
The most important feature of
Network Separation environment provided by ClouDoc is to prevent information
leakage by a malignant code as well as by human. It is a well-known fact that recent
various information leak incidents were caused not by malignant codes but by
inside staff or vender staff. Besides, ClouDoc is designed to interrupt random
deletion of a document by an external malignant code.

Document
centralization solution based Network Separation will help construct security
environment for a company or public office!
Cloudoc NetworkLock function is based on
document centralization solution. Even if connected with the internet, as an
important document does not exist in the hard disk of PC under this
environment, information leakage is prevented.
l As user work environment is almost same as the existing one,
operational confusion can be minimized.
l As there is not any physical change in the existing network from the
viewpoint of a manager, the system can be introduced without big difficulties.
l The advantage from the viewpoint of CEO is that it is not necessary
to purchase licenses of various software in double.
Until recently, many organizations are required
to adopt Network Separation but total Network Separation is not a simple issue
if we perform it in the existing way. Besides, despite the above-mentioned
complicated much work, it is difficult to obtain additional effect except but
prevention of information leakage by a malignant code. However, as ClouDoc has
a Network Separation function based on document centralization solution, it
helps achieve a productive objective (Management based
on knowledge) additionally as well as a security objective. It may be
recommendable for an organization to consider the adoption of NetworkLock based
on document centralization solution, so as to achieve both security and work
innovation.
