Abstract: An apparatus for detecting a partial discharge (PD) signal capable of detecting a PD signal of a power device includes: a partial discharge (PD) coupler connected to a ground side of a power device and configured to cancel a low frequency noise component including a commercial frequency from an AC component flowing through the ground side of the power device when a partial PD signal is generated from the power device, and to allow a high frequency component including a PD signal included in the AC component to pass therethrough to generate a PD analog signal; and a PD detection unit configured to cancel a noise signal from the PD analog signal generated by the PD coupler to detect only the PD signal.

Abstract: Provided is an Internet information security technique, and more particularly, a method for alerting a user that a connected web site is a phishing site by comparing connected web site information with normal site information.To this end, the method includes the steps of: (a) extracting information on a presently connected site; (b) if information on a normal site having the same domain as the connected site exists in a database, comparing the connected site information with the normal site information; and (c) if the connected site information does not match the normal site information, alerting a user that the connected site is a phishing site. Therefore, the user may safely use the Internet by confirming whether the connected web site is a phishing site.

Abstract translation: 提供了一种互联网信息安全技术，更具体地，涉及通过将连接的网站信息与正常的站点信息进行比较来提醒用户连接的网站是钓鱼网站的方法。 为此，该方法包括以下步骤：（a）提取当前连接的站点的信息; （b）如果在数据库中存在与连接站点具有相同域的正常站点的信息，则将所连接的站点信息与正常站点信息进行比较; 和（c）如果所连接的站点信息与正常站点信息不匹配，则提醒用户该连接站点是钓鱼站点。 因此，用户可以通过确认所连接的网站是否是网络钓鱼站点来安全地使用因特网。

Abstract: Provided are an apparatus and method of detecting and controlling a privilege level violation process. The apparatus monitors whether higher-privileged processes depend on information provided from lower-privileged objects or denies the higher-privileged processes to access the lower-privileged objects. The apparatus is provided in a process, and monitors whether a process accesses to a lower-privileged object. The apparatus gives a warning message or denies an access of the process to the lower-privileged object when it detects that the higher-privileged process access to the lower-privileged object. Therefore, the apparatus of detecting and controlling a privilege level violation process detects weaknesses that may be caused by privilege level violation, thus allowing a system to be safely operated.

Abstract translation: 提供了一种检测和控制特权级别违反过程的装置和方法。 该设备监控较高权限的进程是否依赖于从较低特权对象提供的信息，或拒绝较高权限的进程访问较低权限的对象。 该设备被提供在一个进程中，并且监视进程是否访问较低特权对象。 当设备检测到较高权限的进程访问较低权限的对象时，该设备会发出警告消息或拒绝对低级特权对象的访问。 因此，检测和控制特权级别违规处理的装置检测可能由特权级别违规引起的弱点，从而允许系统安全地操作。
