  • Publication number: 20110219454
    Abstract: Provided is a method of identifying an ActiveX control distribution site, detecting a security vulnerability in an ActiveX control and immunizing the same. A security vulnerability existing in an ActiveX control may be automatically detected, effects brought on by the corresponding security vulnerability may be measured, and abuse of the detected security vulnerability in a user PC to be protected may be immediately prevented. Therefore, since the user PC may be protected regardless of a security patch, it is anticipated that security problems in the Internet environment caused by imprudent use of the ActiveX control may be significantly enhanced.

  • Publication number: 20090313699
    Abstract: An apparatus and method for preventing an anomaly of an application program are provided. More particularly, an apparatus and method for preventing an anomaly of an application program that detect and stop an anomaly on the basis of a behavior profile for an application program are provided. The apparatus includes a behavior monitor that detects behavior of an application program in operation, an anomaly detector that determines whether the detected behavior of the application program is an anomaly on the basis of a behavior profile of the application program in operation, and an anomaly stopper that stops the behavior of the application program determined as an anomaly by the anomaly detector.

  • Publication number: 20080115221
    Abstract: Provided are a system and method for predicting a cyber threat. The system and method collect various variables and synthetically predict the frequency, dangerousness, possibility, and time of the occurrence of a cyber threat including hacking, a worm/virus, a Denial of Service (DoS) attack, illegal system access, a malicious code, a social engineering attack, system/data falsification, cyber terror/war, weakness exploitation, etc., using a time-series analysis method and a Delphi method, and inform a user in advance of the prediction result, thereby enabling the user to prepare against the cyber threat.
