Abstract: A method for providing a browser using browser processes separated based on access privileges and an apparatus using the method. The method includes acquiring a first address corresponding to a first webpage; acquiring a first set of terminal access privileges based on the first address from a privilege control list and executing a first browser process corresponding to the first set of terminal access privileges; determining whether to allow rendering by comparing the first set of terminal access privileges with a second set of terminal access privileges corresponding to a second webpage when the first browser process attempts to render the second webpage; and if the rendering is not allowed, blocking the first browser process from rendering and rendering the second webpage by executing a second browser process corresponding to the second set of terminal access privileges.

Abstract: 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.

Abstract: An apparatus and method for detecting a Hyper Text Transfer Protocol (HTTP) botnet based on the densities of transactions. The apparatus includes a collection management unit, a web transaction classification unit, and a filtering unit. The collection management unit extracts metadata from HTTP request packets collected by a traffic collection sensor. The web transaction classification unit extracts web transactions by analyzing the metadata, and generates a gray list by arranging the extracted web transactions according to the frequency of access. The filtering unit detects an HTTP botnet by filtering the gray list based on a white list and a black list.
