Abstract: An anomaly detection method includes collecting and preprocessing time series data every preset detection cycle; detecting an anomaly in time series data preprocessed for a current detection cycle using a deep learning model trained with an unsupervised learning scheme using features of time series data of a previous detection cycle; retraining the deep learning model by further using the time series data preprocessed for at least one detection cycle included in the current learning cycle; and detecting an anomaly in time series data collected and preprocessed for a detection cycle after the current learning cycle using the retrained deep learning model.

Abstract: A URL collecting method includes accessing, by a URL collecting apparatus, a web server of a first URL; receiving, by the URL collecting apparatus, a first web page from the web server; and a URL dynamic collecting step of collecting, by the URL collecting apparatus, one or more URLs invoked while performing some or all of source codes of the first web page.

Abstract: A URL address determining method includes receiving a URL address extracted from a target server; requesting a response corresponding to the URL address from the target server; when receiving response data from the target server, extracting a response URL address corresponding to the URL address from the response data; and determining a resource indicated by the URL address by using the response URL address.

Abstract: A method for determining duplication of a vulnerability may include a vulnerability extraction step of extracting vulnerability uniform resource locator (URL) addresses including the vulnerability from an analysis target server; a hash generation step of generating the URL hash value corresponding to the extracted vulnerability from the vulnerability URL address; and a duplication determination step of determining, when the URL hash value is present in the first comparison table, that the vulnerability is duplicated and excluding the corresponding vulnerability from vulnerability information.

Abstract: An input recognition method carried out by an electronic device implemented by a computer comprises the steps of generating a virtual grid of which the distance between lines is variable, in correspondence with at least a partial region of a display included in or connected to the electronic device; and recognizing, by using an index of the virtual grid, a position selected by a user of the electronic device in the region of the display corresponding to the virtual grid.

Abstract: A method for analyzing vulnerabilities may include: an analysis target URL receiving step of receiving a plurality of analysis target uniform resource locator (URL) addresses extracted from the analysis target server; an identification key setting step of setting respective identification keys corresponding to the plurality of analysis target URL addresses; a vulnerability analyzing step of performing a simulated attack so as to access the external server by the analysis target server by inserting an analysis hypertext transfer protocol (HTTP) request sentence including a URL address of an external server and the identification key into the analysis target URL address; an access record checking step of requesting an access record of the analysis target server to the external server; and a vulnerability extracting step of extracting a vulnerability of the analysis target server by using the identification key included in the access record.

Abstract: A global cloud network quality measurement method may include generating an Internet protocol (IP) list of open web servers having at least one externally open port for each country; collecting packet data through communication with each of the open web servers based on the IP list; and analyzing a network quality with respect to at least one of a region, an Internet service provider (ISP), and an autonomous system number (ASN) based on the collected packet data.

Abstract: A URL processing method includes a response data determining step in which a URL processing apparatus determines whether to exclude one or more URLs included in a first web page from a valid URL list using header information for the first web page of a first web site and a similarity based valid URL calculating step of estimating a similarity between web pages corresponding to respective URLs according to a predetermined criterion with respect to one or more URLs included in the first web page and selecting some of URLs of a similar web page calculated according to the similarity and adding the selected URLs in the valid URL list.

Abstract: An air-conditioning apparatus using a heat pipe is provided, where the state of the outside air is compared with the state of set supply air. The heat exchange and mixed supply of outside air and ventilation air are effectively performed by changing the passage of the ventilation air and the outside air through the selective opening/shutting of dampers, cooling the outside air through latent heat by spraying mist, and by controlling supply air in a set state through the cooling and humidification of the supply air. Accordingly, energy efficiency can be improved and the energy necessary for the air-conditioning apparatus can be reduced using the evaporation latent heat of water. Furthermore, operation costs can be reduced and financial gains can be obtained because an efficient operation can be performed in response to the state of a measured outside air.

Abstract: Provided is a method of manufacturing a server room cooling apparatus, the method including: providing a housing; providing at least one frame in the housing; providing, on the at least one frame, a barrier wall configured to divide a space inside the housing into at least two spaces; forming a mist ejection unit configured to eject mist to an outer air supplied from outside the server room cooling apparatus, at a side of a supply unit that is formed by the barrier wall and supplies outer air to a server room; forming a filter unit configured to filter outer air supplied from outside the server room cooling apparatus, at a side of the mist ejection unit; and forming an outer air inflow unit into which outer air flows, at one side of the filter unit.
