Abstract: According to one aspect of the present invention, there is provided a local data protection system including a data protection agent program installed on a local computing device, which, in accordance with a preset security policy, directs storage of data files stored on the local computing device to a security area, and performs predetermined data protection functions to prevent data in storage from being leaked, lost, stolen or otherwise compromised.

Abstract: Provided is a system for blocking a phishing attack including: a phishing attack prevention storage device; wherein a user terminal or a service server is connected with the phishing attack prevention storage device via a network, wherein a storage area in the phishing attack prevention storage device is mounted in a network drive at the user terminal or the service server, wherein when there is an open request for a real file stored in the storage area in the phishing attack prevention storage device from the user terminal or the service server, the phishing attack prevention storage device checks a storage operation mode and creates a fake file other than the open-requested original file when the storage operation mode corresponds to a list-only mode to return the fake file to the user terminal or the service server via the network.

Abstract: Provided is a system for blocking a phishing attack including a phishing attack prevention storage device, and an agent program which is installed in a user terminal or a service server and performs an interworking operation with the phishing attack prevention storage device when the user terminal or the service server is connected with the phishing attack prevention storage device via a network. According to the embodiment of the present invention, when there is an open request for the file stored in the phishing attack prevention storage device from the user terminal or the service server, the phishing attack prevention storage device may check a storage operation mode and create a fake file other than the open-requested original file when the storage operation mode corresponds to a list-only mode to return the fake file to the user terminal or the service server.

Abstract: A server for blocking a ransomware attack includes a backup storage device which has a purpose for backing up the stored data in a server as a separate storage device which is physically independent from the server and includes a communication interface to enable a communication access to the server; and a service agent which is installed in the server to mediate the communication with the backup storage device.

Abstract: Provided is a system for blocking an external attack, which includes: a network file server; and a network file server (NFS) client installed in a user terminal or a service server and communication-connected with the network file server which is remotely positioned, and the network file server determines, when there is an access or opening request of a file stored in the network file server mounted in the user terminal or service server in a network drive format from the NFS client, whether at least one of the user information and the program information to request the access or opening is authorized and blocks the access to the file which is requested to be accessed or provides the file of which opening is requested to the NFS client only in a read only mode when the access or opening request is unauthorized according to a determination result.

Abstract: A system for providing a hybrid WORM disk, includes: a network file server; and a network file server (NFS) client installed in a user terminal or a service server and communicatively connected to the network file server which is located remotely from the NFS client, wherein the network file server has a mode setting function which allows a disk drive, which is mounted in the form of a network drive in the user terminal or the service server, to operate in any one of a general disk mode in which creating, reading, modifying, deleting, and the like are possible, and a Write Once Read Many (WORM) disk mode in which only creating and reading are possible.

Abstract: The present invention relates to a method for, when using security software which allows documents to be utilized in PCs and terminals in companies or institutions but not to be leaked therefrom, enabling members to view, generate, edit and delete work files that are generated in the course of business in only secure areas and to freely view, generate and edit non-business personal documents with the same PCs and the same editing software in non-secure areas. More specifically, the present invention relates to a method for, when a program enabling access to a certain secure storage space is set to be a security program, allowing the program to be driven only in the secure storage space by pre-copying a temporary work file (cache file), a folder path, a license file, etc.
