A mobile ad-hoc network (MANET) may include a plurality of nodes for transmitting data therebetween and a policing node. The policing node may detect intrusions into the MANET by monitoring transmissions among the plurality of nodes to detect transmissions during an unauthorized period and generate an intrusion alert based thereon. The policing node may also detect intrusions based upon one or more of integrity check values which do not correspond with respective data packets, usage of non-consecutive media access control (MAC) sequence numbers by a node, and collisions of packet types and/or MAC addresses.

Various embodiments of methods and systems for adaptive thermal management techniques implemented in a portable computing device (“PCD”) are disclosed. Notably, in many PCDs, temperature thresholds associated with various components in the PCD such as, but not limited to, die junction temperatures, package on package (“PoP”) memory temperatures and the “touch temperature” of the external surfaces of the device itself limits the extent to which the performance capabilities of the PCD can be exploited. It is an advantage of the various embodiments of methods and systems for adaptive thermal management that, when a temperature threshold is violated, the performance of the PCD is sacrificed only as much and for as long as necessary to clear the violation before authorizing the thermally aggressive processing component(s) to return to a maximum operating power.

A data processing apparatus is provided which allows easy identification of a correspondence relationship between a trace packet and a performance packet. The data processing apparatus includes: a measurement trigger generation unit that generates a measurement trigger; a performance monitor unit that measures a performance measurement event collected from a central processing unit (CPU) and outputs a measurement value; and a CPU trace unit that generates a trace packet sequence of trace information including an operation record of the CPU. Upon receipt of the measurement trigger, the performance monitor unit starts or ends measurement of performance metrics or outputs the measurement value, while, upon receipt of the measurement trigger, the CPU trace unit generates a trigger packet indicating generation of the measurement trigger and inserts the trigger packet, at a position corresponding to timing with which the measurement trigger is generated, into the trace packet sequence.

A countermeasure for a computer security threat to a computer system is administered by establishing a baseline identification of an operating or application system type and an operating or application system release level for the computer system that is compatible with a Threat Management Vector (TMV). A TMV is then received, including therein a first field that provides identification of at least one operating system type that is affected by a computer security threat, a second field that provides identification of an operating system release level for the operating system type, and a third field that provides identification of a set of possible countermeasures for an operating system type and an operating system release level. Countermeasures that are identified in the TMV are processed if the TMV identifies the operating system type and operating system release level for the computer system as being affected by the computer security threat. The received TMV may be mutated to a format for processing of the countermeasure.

To secure the confidentiality of data stored in data storage devices, a position determination system is mechanically coupled to the data storage devices and continuously determines a position thereof. A processor, provided with an authorized location for the data storage devices, facilitates transfer of data to and from the data storage devices. Specifically, when the position of the data storage devices matches the authorized location, the processor facilitates transfer of data from the data storage devices without any modification of the data. However, when the position of the data storage means does not match the authorized location, the processor inflates the data by dispersing it in a very large set of irrelevant data.

The invention discloses a Linux kernel page table replacement-based method for tracking a memory access model. As different between the speed of a processor and the memory access speed becomes larger and larger, a memory system becomes a bottleneck of system performance. Application programs of different natures have different memory access models and different memory behavior optimization modes. However, the prior tool cannot track the memory accesses of the programs effectively and therefore causes complex memory optimization. The method of the invention is used in a Linux system and replaces the page table of a target process by changing Linux kernel. A new page table stores only one item of a non-code segment web page, so missing page interrupt occurs every time the target process accesses a memory and virtual page access sequence of the specific target process, namely, the memory access model of programs can be tracked by recording corresponding address when the kernel processes the missing page. The method has the characteristic of light weight, and can quickly track memory access, track out a small amount of data and avoid influencing the normal operation of other processes in an operation system. The method for tracking the memory access model can guide the optimization of memory behaviors.
