Despite over two decades of research, high false alarm rates, large trace sizes and high processing times remain among the key issues in host-based anomaly intrusion detection systems. In an attempt to reduce the false alarm rate and processing time while increasing the detection rate, this paper presents a novel anomaly detection technique based on semantic interactions of system calls. The key concept is to represent system calls as states of kernel modules, analyze the state interactions, and identify anomalies by comparing the probabilities of occurrences of states in normal and anomalous traces. In addition, the proposed technique allows a visual understanding of system behaviour, and hence a more informed decision making. We evaluated this technique on Linux based programs of UNM datasets and a new modern Firefox dataset. We created the Firefox dataset on Linux using contemporary test suites and hacking techniques. The results show that our technique yields fewer false alarms and can handle large traces with smaller (or comparable) processing times compared against the existing techniques for the host based anomaly intrusion detection systems.

INCOSE International Symposium 2014年第1期17卷

作者： Kristen Baldwin Dr. Charles Dickerson Dr. Abe Meilich John Osterholz Malcolm Touchin Dr. Steve Bratt Panelist Deputy Director Office of the Secretary of Defense (OSD) Software Engineering and System Assurance Office of the Deputy Under Secretary of Defense Acquisition and Technology Chair INCOSE Architecture Working Group (AWG) INCOSE AWG Leadership Team former Director BAE Systems Architecture and Interoperability for the DoD Chief Information Officer Technical Manager Systems Engineering Innovation Centre (SEIC) Loughborough University CEO W3C (invited) World Wide Web Consortium (W3C)

In May 2006, a task was issued by the U.S. Deputy Under Secretary of Defense for Acquisition and Technology (DUSD (A&T)) to develop a systems of systems engineering Guidebook. The Office of the Secretary of Defense (OSD) convened a small group of Government, Industry and Academia, and selected the Stevens Institute of Technology to lead the project. During the summer and autumn of 2006, the International Council on systems engineering (INCOSE) was honored to be invited to provide a global representation of the systems engineering community in support of the OSD writing of a systems of systems, systems engineering (SoS SE) Guide. On 22 December 2006 the draft SoS SE Guide, version 0.9, was released for review and use by the systems engineering community. Industry and academia have been asked to submit their comments as part of the effort to pilot the recommendations in the Guide. In 2007, OSD has been actively engaging a sample of DoD SoS programs to pilot the Guide, especially with respect to the 16 OSD SE processes. The responses will become part of the first update to the Guide. At this panel, OSD will present the background and motivation for writing the Guide, along with an update on the pilot. Both OSD and INCOSE will discuss their insights. As part of the broad SE community review, the Guide will also be viewed from the UK perspective of Capabilities Based Acquisition. Looking to the future, the concepts and practices of Net Centricity, Network Enablement of Capabilities, and Semantic Web will be considered and how they might be more deeply integrated into future versions of the Guide. This panel will provide opportunities for INCOSE to continue to work with OSD and collaborate on SoS SE.

With the fast development of highly-integrated distributed systems (cluster systems), designers face interesting memory hierarchy design choices while attempting to avoid the notorious disk swapping. Swapping to the free remote memory through Memory Collaboration has demonstrated its cost-effectiveness compared to over provisioning the cluster for peak load requirements. Recent memory collaboration studies propose several ways on accessing the under-utilized remote memory in static system configurations, without detailed exploration of the dynamic memory collaboration. Dynamic collaboration is an important aspect given the run-time memory usage fluctuations in clustered systems. Further, as the interest in memory collaboration grows, it is crucial to understand the existing performance bottlenecks, overheads, and potential optimization. In this paper we address these two issues. First, we propose an Autonomous Collaborative Memory system (ACMS) that manages memory resources dynamically at run time to optimize performance. We implement a prototype realizing the proposed ACMS, experiment with a wide range of real-world applications, and show up to 3x performance speedup compared to a non-collaborative memory system without perceivable performance impact on nodes that provide memory. Second, we analyze, in depth, the end-to-end memory collaboration overhead and pinpoint the corresponding bottlenecks. © 2012 IEEE.

Cancer is becoming a leading cause of death among people in the whole world. It is confirmed that the early detection and accurate diagnosis of this disease can ensure a long survival of the patients. Expert systems and machine learning techniques are gaining popularity in this field because of the effective classification and high diagnostic capability. This paper presents the application of rough set theory for clustering two cancer datasets. These datasets are taken from UCI ML repository. The method is based on MDA technique proposed by [11]. To select a clustering attribute, the maximal degree of the rough attributes dependencies in categorical-valued information systems is used. Further, we use a divide-and-conquer method to partition/cluster the objects. The results show that MDA technique can be used to cluster to the data. Further, we present clusters visualization using two dimensional plot. The plot results provide user friendly navigation to understand the cluster obtained.

SOFT SET-BASED DECISION MAKING FOR PATIENTS SUSPECTED INFLUENZA-LIKE ILLNESS

引用

International Journal of Modern Physics: Conference Series 2012年第9期ijmpcs卷 259-270页

In previous work, we presented an applicability of soft set theory for decision making of patients suspected influenza. The proposed technique is based on maximal supported objects by parameters. At this stage of the research, results are presented and discussed from a qualitative point of view against recent soft decision making techniques through an artificial dataset. In this paper, we present an extended application of our soft set-based decision making through a Boolean valued information system from a dataset of patients suspected ILI (Influenza-Like Illness). Using soft set theory and maximal symptoms co-occurences in patients, we explore how soft set-based decision making technique can be used to reduce the number of dispensable symptoms and further make a correct and fast decision. The result of this work can be used for recommendation of decision making based on the clusters decision captured. Finally, this technique may potentially contribute to lowering the complexity of medical decision making without loss of original information.

Airplane manufacturers are under an increasing pressure to integrate new hardware into the cabin of their planes. Clearly, this comes along with a need for changing and extending the attached software platforms as well. Anecdotally, these systems have often been criticized as hard to maintain. However, in practice there exists no scientifically sound analysis of their maintainability so far. As a first step towards such an analysis, we present the results of applying common software metrics on the cabin software of a current commercial passenger airplane in this paper and discuss their implications for its maintainability.

IEEE Annual International Computer software and Applications Conference (COMPSAC)

Deployed software applications use log files to keep a record of system events. Log analysis provides support for system administrators to gain the knowledge of system health and behavior. As a result, the ability to efficiently search for patterns in historical events has become a major requirement for timely analysis. Enterprise systems today produce high volumes of log data, regularly in the order of thousands of events per second, which requires to build inverted indexes for quick data retrieval. However, current inverted indexing techniques are rarely designed to handle high volumes of dynamic stream data and often resource consuming. We propose an efficient indexing solution, which reduces the necessary resources by employing bloom filter techniques. The solution builds a generic indexing engine for the Run Time Correlation Engine logging framework to achieve efficient monitoring in the Cloud. In particular, our solution is able to deliver significant performance improvement over existing indexing engines.
