| 20150237027 | APPARATUS, METHOD AND SYSTEM FOR CONTEXT-AWARE SECURITY CONTROL IN CLOUD ENVIRONMENT - An apparatus, method and system for context-aware security control in a cloud environment are provided. The apparatus includes an authentication header inspection unit and a packet data processing unit. The authentication header inspection unit generates an authentication header based on the received context information and key of a user, compares the generated authentication header with the authentication header of packet data received from a remote user terminal, and outputs the results of the comparison. The packet data processing unit performs one of the transmission, modulation and discarding of packet data from the cloud server of a cloud service network based on the results of the comparison by the authentication header inspection unit. | 08-20-2015 |
| 20150326611 | SECURITY CONTROL APPARATUS AND METHOD FOR CLOUD-BASED VIRTUAL DESKTOP - The security control apparatus includes a network control unit for receiving a security protocol-based packet that includes a protocol control header and data and that is transmitted between a cloud-based virtual desktop interaction remote agent unit and a virtual machine of a cloud-based virtual desktop interaction device, and blocking network traffic between cloud-based virtual desktop interaction remote agent unit and the virtual machine, depending on received results of checking. A policy checking unit checks whether information extracted from the security protocol-based packet is compliant with control policies, and transmits results of checking to the network control unit. If the information is not compliant with the control policies, a security solution interaction unit transmits the extracted information to an external security solution, and transmits results of checking by a corresponding security solution to the network control unit. | 11-12-2015 |
| 20160065595 | APPARATUS AND METHOD FOR PERFORMING REAL-TIME NETWORK ANTIVIRUS FUNCTION - An apparatus and method for performing a real-time network antivirus function, which can perform, at high speed, real-time antivirus scanning on a transmission file in a network to be protected and blocking of a malicious file. The apparatus includes a packet processing unit for parsing input packets and outputting a transmission data stream, a packet-based checksum calculation unit for calculating a checksum of the transmission data stream for each packet, and outputting a signature included in the transmission data stream when a last packet of the transmission data stream is input, a virus scanning unit for performing virus scanning based on the signature, a detection and blocking unit for blocking each input packet or transmitting it to a destination, based on result of the virus scanning unit, and a caching unit for updating a blacklist, based on result of the detection and blocking unit. | 03-03-2016 |
| 20160092679 | INSPECTION AND RECOVERY METHOD AND APPARATUS FOR HANDLING VIRTUAL MACHINE VULNERABILITY - An inspection and recovery method and apparatus for handling virtual machine vulnerability, which inspect the security status of a virtual machine in a hypervisor domain, and recover a main system file or limit the use of a virtual machine suspected of being damaged due to hacking depending on the results of inspection, thus providing a secure virtual machine use environment for cloud computing. In the presented method, collection target information and inspection criteria including vulnerability inspection criteria, recovery criteria, and hacking damage criteria are updated. Then, the collection target information is collected from the virtual disk and virtual memory of each virtual machine. Vulnerability is inspected in conformity with the inspection criteria, based on the collected information. A damaged main system file depending on inspection results is recovered based on recovery criteria. | 03-31-2016 |
