Disclosed herein are an apparatus and method for generating evidence video. The apparatus includes a video object indexing unit, a video object search unit, and an evidence video generation unit. The video object indexing unit recognizes an object by storing and analyzing videos received from multiple surveillance cameras, extracts the features of the recognized object, and then generates object metadata. The video object search unit compares received search conditions with the object metadata, and then outputs search results, including the feature information of at least one object, which corresponds to the search conditions. The evidence video generation unit generates an evidence video by aggregating only videos including a specific object selected from the search results.

An apparatus and method for visualizing a network condition related to a network security are provided. The apparatus includes a traffic feature extracting unit, a network condition displaying unit, and a traffic abnormal condition determining unit. The traffic feature extracting unit extracts information including source address, source port, destination address, and destination port from network traffics, selects two of the extracted information, and calculates unique dispersion degrees of two unselected information. The network condition displaying unit displays a two-dimensional cube expressed using the calculated unique dispersion degrees for the classified traffics. The traffic abnormal condition determining unit determines whether the traffics are in an abnormal condition or not based on the two-dimensional security cube.
