Information Analysis

— Today’s growing number of security threats to computers and networks also increase the importance of log inspections to support the detection of possible breaches. The investigation and assessment of security incidents becomes more and more a dai-ly business. Further, the manual log analysis is essentially in the context of developing signatures for intrusion detection systems (IDS), which allow for an automated defense against security attacks or incidents. But the analysis of log data in the context of fo-rensic investigations and IDS signature development is a tedious and time-consuming task, due to the large amount of textual data. Moreover, this task requires a skilled knowledge to differentiate between the important and the non-relevant information. In this paper, we propose an approach for log resp. audit data representation, which aims at simplifying the analysis process for the secu-rity officer. For this purpose audit data and existing relations between audit events are ...

SEMATECH has sponsored a “Test Method Evaluation” study to understand the trade-offs among the most common test methodologies used in the industry. This paper presents the results of the failure analysis portion of that project. The testing, reliability stressing, characterization, fault diagnosis and physical analysis results are presented for 25 devices including “IDDq-only” failures and “delay test-only” failures

Information analysts must rapidly assess information to determine its usefulness in supporting and informing decision makers. In addition to assessing the content, the analyst must be confident about the quality and veracity of the information. Visualizations can concisely represent vast quantities of information, thus aiding the analyst to examine larger quantities of material; however, visualization programs are challenged to incorporate

In the mostly self-regulated arboricultural industry, Louisiana, U.S., is one of a few places where arborists must possess a license to operate. Since 1993, state-licensed arborists in Louisiana have been required to attend at least one continuing education workshop each year to maintain their licenses. In 2002, the State of Louisiana assumed responsibility for providing arborist continuing education, and program planners identified increasing safety and professionalism among licensed arborists as the two primary goals for the training program. The authors collected written questionnaires from 386 licensed arborists who provided baseline data on their levels of safety and professional- ism and demographic information. Analysis suggested that safety and professionalism are not separate variables among respon- dents, but examination of categories of questions describing different aspects of safety and professionalism is revealing. Arborists self-reported good ethical practices in deal...

The performance of target identification can be improved by fusing the data from multiple sensors. Even though distributed fusion has advantages of lower communication bandwidth, less processing at a central location, and increased robustness over centralized fusion, it has to address technical issues such as the conditional dependence of information to be fused by a fusion agent. This paper presents distributed fusion and communication management algorithms for target identification. Information graphs are used to select fusion architectures that minimize the effect of information double counting due to communication. Bayesian networks are used to model the target identification problem and identify the sufficient information that needs to be communicated between processing agents for optimal fusion. Communication strategies are developed to determine when a fusion agent should communicate with another fusion agent. Simulation examples demonstrate the performance of distributed fus...

The advanced traveler information system (ATIS) is a type of intelligent transportation system application areas that implements emerging computer, communication, and information technologies to provide vital information to the users of a system regarding traffic regulation, route and location guidance, hazardous situations and safety advisory, and warning messages. ATIS requires a large amount of data for processing, analysis, and storage for effective dissemination of traveler information to users. A geographical information system (GIS) allows large data to be effectively processed, stored, analyzed, logically associated, and graphical displayed. Thus, GIS-based ATIS provides a convenient and powerful tool for storage and graphical representation of information, which can be useful users. Further, by availing the powerful GIS functionalities, a user can conceive a problem and allow the appropriate software to assist him in the decision-making process regarding optimum route selec...

Hurricanes are the costliest natural disasters in the United States. Understanding both hurricane frequencies and intensities is a topic of great interest to meteorologists, decision makers and the general public alike. Previous research has suggested that damage has been dramatically increasing within the last two decades, in part due to rapid increase of population and wealth in coastal regions (Blake et al., 2005; Emanuel, 2005;

The goal of this research was to describe the ability of human operators to interact with adaptive automation (AA) applied to various stages of complex systems information processing, defined in a model of human-automation interaction. Forty participants operated a simulation of an air traffic control task. Automated assistance was adaptively applied to information acquisition, information analysis, decision making, and action implementation aspects of the task based on operator workload states, which were measured using a secondary task. The differential effects of the forms of automation were determined and compared with a manual control condition. Results of two 20-min trials of AA or manual control revealed a significant effect of the type of automation on performance, particularly during manual control periods as part of the adaptive conditions. Humans appear to better adapt to AA applied to sensory and psychomotor information-processing functions (action implementation) than t...

Modern automobiles come with a high degree of electron- ics and an enormous amount of in-car communication ac- tivities. This leads to an increasingly complex data volume which challenges automotive engineers in detecting and ana- lyzing erroneous communication processes. In this paper, we present results of our studies on current working behaviour and environments of analysis and diagnosis experts in

This paper describes the interface design of our AeSon (Aesthetic Sonification) Toolkit motivated by user-centred customisation of the aesthetic representation and scope of the data. The interface design is developed from 3 premises that distinguish our approach from more ubiquitous sonification methodologies. Firstly, we prioritise interaction both from the perspective of changing scale, scope and presentation of the data and the user's ability to reconfigure spatial panning, modality, pitch distribution, critical thresholds and granularity of data examined. The user, for the majority of parameters, determines their own listening experience for real-time data sonification, even to the extent that the interface can be used for live data-driven performance, as well as traditional information analysis and examination. Secondly, we have explored the theories of Tufte, Fry and other visualization and information design experts to find ways in which principles that are successful in ...

In this paper, we will discuss how we can get Kerberos passwords by capturing a single packet, encrypted using the RC5-HMAC encryption type. We will discuss how presently existing two methods that when combined together, can reduce the time needed to crack a password redused over brute force and will propose scheme how that time can reduce more. The first
