Work Environment Before ImplementationWhile documents are managed individually, only few documents are registered with the system and utilized by others. All unregistered documents are buried when the user leaves the company, and sometimes they are copied off by the user when he leaves.

Work Environment After ImplementationIntroduction of file server causes most documents stored in individual PCs to become the corporate asset. Documents stored centrally are protected with the security function, and change-over at the time of leave of an employee becomes easy.

Own protocol, own engine Connection to Virtual Drive

For simplified system management and scalability for future

functional need, one needs to have the 100% proprietary

technology that enables Windows Explorer UI provision.

This solution provides scalability to accommodate future

functional need by determination of its own protocol. The server

engine and the client engine also have been implemented by the

Company’s own technologies to ensure independence on

external resources.

This solution offers environment where Personal and Tem

Documents Drives are used in the Windows Explorer as if they are

used in a local disc. Personal Documents Drive, Team

Documents Drive and Shared Folders Drive can be named as

and mapped to Z: and Y: like in a PC.

Various security functions such as transmission section encryp-

tion, encrypted file system and security log are embedded in

these virtual drives.

SecuritySecurity function is an essential part of a solution that is used to store corporate documents. The solution encrypts and stores user’s passwords in the SHA1 method, and locks the account when a series of login failure occurs.

By applying the authentication certificate to the Server, SSL transmission from PC to the server sections can be bug-free. The ARIA encryption for storage can protect document confidentiality even in case of accidental data leak.

Account Management Account Lock An account with a series of login failure with wrong password above the set number of tries is automatically disabled until it is released by the Administrator.

Password Complexity Various levels of password complexity are available for users to set their password.

Password Expiration Users are requested to change their password regularly at the set interval.

Authentication Security Logi Security are enhanced by 128-bit SSL encrypted transmission of user’s ID and password entered remotely.

IP Authentication The IP section authorized by Administrator, the IP address registered by the user and authorized by Administrator, and login from such section is only authorized.

PKI Authentication Authentication of the users who use API supplied by PKI Solution are enabled, and linkage with GPKI is also enabled.

Network Security IP Filtering Authorization by IP section for detailed functions such as document upload/download and View List can be set to procure security.

File Security Encrypted Transmission Section Bugging is prevented by 128-bit SSL encrypted transmission from PC to server.

Security Log Read/Write/Delete/Rename/Copy/Move of all documents within the server as well as user authentication data are recorded.

Encrypted File System The safe and quick encryption method is applied to all documents saved in the Server.

Personal Security Dual Administrators Enterprise Administrator for solutions can be dualized into ‘Data Protection Administrator’

and ‘Service Administrator’ to procure data asset security.

Permission Setting Log The Data Protection Administrator can be given the authority to view permission settings

for Service Administrator and Folder Manager to monitor potential data theft.

Other Security Security for client’s document drives is ensured using various preventive and diagnosis measures such as SQL Injection, Cross Site Script and file integrity checks.
