Abstract:
The present invention relates to a secure distributed file system for various devices. The secure distributed file system according to the present invention includes: a user unit which sets whether to protect data according to the importance of the data set by application program driven on a mobile device; and a kernel unit which provides a means for accessing a file generated by an application program belonging to the user unit or previously generated. The secure distributed file system exposes key pieces more than a threshold, and makes impossible the reconfiguration of original data unless all devices sharing corresponding file pieces are obtained, even when a situation capable of key restoration occurs. The present invention provides the merits of overcoming the inefficiency of an existing protection technique encrypting the entire file, the burden of a cost on the configuration of a distributed file system relying on a central server, and the security vulnerability to files stored in a single device.

Abstract:
An apparatus and a method for integratedly managing invasion detection rules in an IPv4 and IPv6 combined network are provided to easily re-use an already developed IPv4 and IPv6 intrusion detection system by using a framework of an invasion detection rule integrated management. A GUI(Graphic User Interface)(110) receives an intrusion detection rule from the exterior. A correlation analyzer(120) analyzes the correlation between an IPv4 and an IPv6 included in the received intrusion detection rule, and automatically converts the received intrusion detection rule by using the analyzed results. A storage unit(150) stores the correlation information between the converted intrusion detection rule and the IPv4 and the IPv6 in a corresponding database. An IPv4 intrusion detection rule manager(130) manages an intrusion detection rule of an IPv4 and transfers the intrusion detection rule of the IPv4 and the previously stored correlation information to an IPv4-based IDS(Intrusion Detection System)(20). An IPv6 intrusion detection rule manager(140) manages an intrusion detection rule of the IPv6, and transfers the intrusion detection rule of the IPv6 and the previously stored correlation information to an IPv6-based IDS(10).
Abstract:
A method of blocking network attacks using information included in a packet, and an apparatus thereof are provided. The method includes: receiving a packet containing information on the packet including at least information on a source from which the packet is sent, and information on a destination to which the packet is sent; and extracting the information on the packet included in the packet, comparing the information with a predetermined access control condition, and blocking or passing the packet. By doing so, a packet being transferred with a routing header capable of bypassing a security device as in an Internet Protocol version 6 (IPv6) network can be appropriately blocked or passed. Accordingly, security problems caused by the routing header can be overcome, and as a result, usage of the routing header can be promoted. Also, since a routing header can be used for transmitting a packet along a desired path, the routing header can be widely used without security problems, and can ease network security concerns relating to IPv6 networks that are expected to come into increasingly wide use.
Abstract:
An apparatus and a method for preventing conflict of addresses are provided to previously prevent possibility of the address conflict which can be generated when a stateful address autoconfiguration technique and a stateless address autoconfiguration technique are simultaneously provided in the IPv6(Internet Protocol version 6) network environment and when an arbitrary address is manually configured instead of the stateless address autoconfiguration technique, thereby preventing the conflict during network connection of various mobile terminals and home appliances through the stateless address autoconfiguration technique. An apparatus(100) for preventing conflict of addresses comprises the followings: a receiver(110) for receiving a packet if the packet includes an NS(Neighbor Solicitation) message for confirming whether the addresses is used or not on the basis of a header of the packet received by using a promiscuous mode; a uniqueness determiner(120) for determining whether an address, which is included within the received NS message and will be used, is consistent with N number of fixed addresses; and a conflict informer(130) which transmits an NA(Neighbor Advertisement) message showing that the address, which will be used, is redundant if the address which will be used is consistent with an address, which is not configured yet, among the N number of fixed addresses.
