摘要： In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products for identifying that an application program does not have permission to access a first type of data that is provided by a first application program. A computing system identifies that a second application program has permission to access the first type of data. The second application program provides a second type of data and is able to modify the second type of data to include the first type of data. The computing system identifies that the application program has permission to access the second type of data. The computing system determines that the second type of data includes the first type of data. The computing system performs an action to prevent the first type of data from being provided from the second application program to the application program without user authorization.

摘要： There is described a method of protecting an item of software so as to obfuscate a condition which causes a variation in control flow through a portion of the item of software dependent on whether the condition is satisfied, wherein satisfaction of the condition is based on evaluation of one or more condition variables. The method comprises: (i) modifying the item of software such that the control flow through said portion is not dependent on whether the condition is satisfied; and (ii) inserting a plurality of identity transformations into expressions in said portion of the modified item of software, wherein the identity transformations are defined and inserted such that, in the absence of tampering, they maintain the results of the expressions if the condition is satisfied and such that they alter the results of the expressions if the condition is not satisfied, wherein each identity transformation is directly or indirectly dependent on at least one of the one or more condition variables. New variables may be defined as part of this method. There are also described associated apparatuses, computer programs and the like.

摘要： A network intrusion detection system and method is configured to receive off-line network traffic. The off-line network traffic with a predefined format, PCAP file, is capable of indicating existence of a plurality of covert channels associated with a corresponding plurality of covert channel signatures. Each covert channel comprises a tool that communicates messages by deviating from a standard protocol to avoid detection. A plurality of covert channel processors are configured to analyze off-line network traffic. The analysis determines whether the off-line network traffic deviates from the standard protocol based on one or more covert channel signatures. The covert channels are employed in at least one standard layer of the standard protocol stack and the off-line network data traffic comprises at least one standard protocol stack having multiple standard layers.

摘要： A computing device may use machine learning techniques to determine the level, degree, and severity of its vulnerability to side channel attacks. The computing device may intelligently and selectively perform obfuscation operations (e.g., operations to raise the noise floor) to prevent side channel attacks based on the determined level, degree, or severity of its current vulnerability to such attacks. The computing device may also monitor the current level of natural obfuscation produced by the device, determining whether there is sufficient natural obfuscation to prevent a side channel attack during an ongoing critical activity, and perform the obfuscation operation during the ongoing critical activity and in response to determining that there is not sufficient natural obfuscation to adequately protect the computing device against side channel attacks.

摘要： A technique allows detection of covert malware that attempts to hide network traffic. By monitoring network traffic both in a secure trusted environment and in an operating system environment, then comparing the monitor data, attempts to hide network traffic can be detected, allowing the possibility of performing rehabilitative actions on the computer system to locate and remove the malware hiding the network traffic.
