Abstract: Proposed is a method for product recommendation by a server. The method may include receiving a gift recommendation request from a first user terminal for a second user, checking available basic information of the second user, and determining a first recommendation information based on the basic information, wherein the first recommendation information comprises a first recommendation reason and at least one product related to the first recommendation reason. The method may also include determining a second recommendation information not based on the basic information, wherein the second recommendation information comprises a second recommendation reason and at least one product related to the second recommendation reason. The method may further include providing recommendation information comprising the first and second recommendation information to the first user terminal. The first recommendation information may be prioritized for display over the second recommendation information.

Abstract: The present invention relates to a method of implementing a security system for preemptively preventing a decrease in work efficiency due to leaked confidential secrets or the browsing of non work-related sites through a mobile terminal. A security manager implements an environment for allowing, blocking, or recording Internet usage in an independent mobile communication network in an area requiring security, uses a security system server to preregister information on mobile terminals of users who are expected to use the Internet, makes agreements on how personal information will be handled when outside visitors visit the network, registers information on mobile terminals of outside visitors with the security system server, and oversees the installation of a security app whenever necessary.

Abstract: The present invention relates to a session-based traffic analysis system that may accurately analyze an amount of traffic for each transmission control protocol (TCP) connection using only one-way packets. The system may accurately analyze an amount of two-way traffic using only one-way connection information.

Abstract: The present invention provides according to an embodiment a method including analyzing traffic; judging whether NAT (Network Address Translation) use of a client configuring and using a private network as well as a being provided an authorized IP address (an Internet IP address) is allowed or not, for analyzing and detecting a number of sharing terminals; creating a database using data; and formulating a policy by using information in the database, so that when users of the private network connect to the Internet at the same time, permission or blocking of Internet use can be executed selectively.

Abstract: The present invention is related to a method for neutralizing a malicious ARP spoofing attack generated in a local network and in particular, the present invention provides a method for neutralizing an ARP spoofing attack comprising a step for detecting an ARP spoofing attack based on an ARP request packet generated for an ARP spoofing attack; a step for generating a plurality of counterfeit MAC addresses and dynamically changing MAC addresses of network devices or servers which are to be protected whenever an ARP spoofing attack is generated; and a step for neutralizing an ARP spoofing attack by using a counterfeit MAC address which is capable of neutralizing an ARP spoofing attack adequately.

Abstract: The present invention is related to a technology for grasping the number of a plurality of terminals of a client using a Cookie in a private network in which plural terminals are shared by redirecting a session which is to be connected to a Web by analyzing a TCP/IP packet, detecting the accurate number of a plurality of terminals of a client using an Internet, and making the accurate number as a DB, and selectively permitting or blocking a connection to Internet according to TCP/IP by using the Cookie pool information of a DB type and JOB when the users configuring and using a private network connect to the Internet at the same time.

Abstract: The present invention provides a method consisting of a step for analyzing a traffic receiving mirroring, a step for judging whether NAT (Network Address Translation) use of a client configuring and using a private network as well as a provided authorized IP (an Internet IP) is allowed or not, for analyzing and detecting the number of sharing terminals, a step for creating a database using data, and a step for formulating a policy by using information in database, so that when the users of a private network connect to Internet at the same time, permission or blocking of Internet use can be executed selectively.
