Abstract: Embodiments can provide a computer implemented method in a data processing system comprising a processor and a memory comprising instructions, which are executed by the processor to cause the processor to implement a system for network protection, the method comprising determining, by the analyzing unit, if an incoming connection comprising one or more packets has a false latency larger than a trigger latency; if the incoming connection latency is larger than the trigger latency, reporting, by the analyzing unit, the incoming connection as a suspicious connection; determining, by the analyzing unit, if an attack is currently in progress; and if the attack is in progress, injecting, by the analyzing unit, at least one of the one or more packets of the incoming connection or one or more packets of an outgoing connection with a false latency.

Abstract: A system and computer program product for preventing abnormal application activity is provided. Packets are retrieved from a packet buffer using packet location information corresponding to information associated with the abnormal application activity in a data processing system. The packets are analyzed to identify content of the network packets causing the abnormal application activity. Network packets containing the content causing the abnormal application activity in the data processing system are blocked.

Abstract: A system, method and computer program product for detecting distributed denial-of-service (DDoS) attacks is provided. Current aggregated flow information for a defined period of time is analyzed. It is determined whether network flow increased above a defined flow threshold value to a second data processing system connected to a network within the defined period of time based on analyzing the current aggregated flow information. In response to determining that the network flow has increased above the defined flow threshold value to the second data processing system connected to the network within the defined period of time, it is determined that the second data processing system is under a DDoS attack.

Abstract: A method for displaying a plug-in frame in a web browser, a computer readable medium, and a computer program product for executing the same are disclosed. The method includes the steps of: constructing each webpage element when a webpage of the web browser is opened or content of a webpage is altered; determining whether each webpage element is a plug-in frame; if yes, obtaining related data of each plug-in frame; arranging each required webpage element from bottom to top to generate a display list; calculating an intersection of each plug-in frame and each webpage element according to the display list; obtaining a new window mask of each plug-in frame according to the related data and the intersection; and displaying each webpage element located above each plug-in frame in the web browser according to the new window mask.
