Intrusion Detection System Based on Integrated System Calls Graph and Neural Networks

Computer security is one of the main challenges of today's technological infrastructures, whereas intrusion detection systems are one of the most widely used technologies to secure computer systems. The intrusion detection systems use a variety of information sources, one of the most important sources are the applications' system calls. The intrusion detection systems use many different detection techniques, e.g. system calls sequences, text classification techniques and system calls graphs. However, existing techniques obtain poor results in the detection of complex attack patterns, so it is necessary to improve the detection results. This paper presents an intrusion detection system model that integrates multiple detection techniques into a single system with the goal of modeling the global behavior of the applications. In addition, the paper proposes a new modified system calls graph to integrate and represent the information of the different techniques in a single data structure. The system uses a deep neural network to combine the results of the different detection techniques used in the global model. The result of the study shows the improvement obtained in the detection results with respect to the use of individual techniques, the proposed model achieves higher detection rates and lower false positives. The proposal has been validated onto three datasets with different levels of complexity.

Motivation for the use of creative accounting techniques in the conditions of the globalized business environment

Although creative accounting is a modern concept, the improvement of business results, their manipulation and fraud in accounting have been known long before its introduction. It is not easy to prepare the conditions for practicing creative accounting, however the current theory is full of knowledge, practices and techniques for its application. The company’s economic results are important especially for owners, investors, the state, banks or competitors. Most often, creative accounting is used to manipulate financial accounting to meet state requirements. Companies are trying to underestimate their economic result in order to minimize the tax liability. Various methods and procedures can be used for this purpose. The aim of the paper is to characterize the creative accounting and motivation that leads to the use of individual techniques of creative accounting, taking into account the specific conditions of the globalized business environment. The paper also presents the advantages and disadvantages of creative accounting. Creative accounting is the boundary between the alternative approaches allowed by legislation and fraudulent financial reporting. Businesses take advantage of weak control and therefore, they can easily hide handling of financial statements. On the other hand the application of creative accounting may be desirable and tolerated under certain circumstances and it can save the business from failure.

Synergistic impact of attenuation correction and gating in routine myocardial SPECT reporting: 2 year follow-up study

To look at the combined impact of non-uniform attenuation correction (AC) and gated SPECT in the visual interpretation of myocardial SPECT imaging. This was compared to the individual benefit obtained by adding AC information and gated SPECT information to non-AC image information. We retrospectively studied a group of 141 patients with a 22-26 month follow-up who underwent myocardial perfusion scintigraphy imaging. All the studies were corrected for attenuation with Gd line source transmission data and were ECG gated. In patients who had abnormal studies, follow-up coronary angiography information was also obtained in addition to medical follow-up information. Two experienced nuclear medicine physicians interpreted the images independently and were blinded to the other person's report. Non-attenuation corrected data was first evaluated followed by attenuation corrected data and gated SPECT data. Four approaches to interpretation of images were undertaken: (1) non-AC images only, (2) non-AC+AC images, (3) non-AC+gated images, and (4) non-AC+AC+gated images. Study results were divided into four categories based on how confident the observers were of the diagnosis: (1) normal, (2) borderline normal, (3) borderline abnormal, and (4) abnormal. When results for sensitivity and specificity using the four different interpretation techniques were compared there was a statistically significant improvement in the specificity compared to non-AC image (48%) with the addition of AC (77%) and gating (82%) information (P<0.001). The best improvement in the specificity was noted when both AC and gated information (91%) was used along with non-AC information. The normalcy rates almost doubled following the addition of AC and gated data. There was also a decrease in the number of borderline results, showing an improvement in the reporter confidence in interpreting myocardial SPECT studies. Sensitivity, however, did not show a significant change between the four different approaches to interpretation of the study. Attenuation correction and gating when combined have a synergistic impact upon improving the specificity of myocardial SPECT reporting when compared to the use of individual techniques alone to improve the specificity.

Techniques for reducing anesthetic injection pain: An interdisciplinary survey of knowledge and application

The authors conducted a study that considered family physicians' and dentists' knowledge and application of techniques to reduce the pain associated with anesthetic injections. They also assessed practitioners' discomfort with patients' injection pain and needle anxiety/phobia. The authors designed a questionnaire about awareness and use of 10 techniques for reducing pain of anesthetic injection and mailed it to 2,000 randomly selected family physicians and general dentists. They analyzed the data to examine differences between disciplines regarding awareness and use of techniques, reasons for not using techniques, number of injections given per week, and predictive value of certain demographic variables on reported use of individual techniques and on practitioner reactions to patients' pain and anxiety. The response rate was 35 percent. The authors used the chi2 test for differences between disciplines' awareness of and use or nonuse of techniques, Wilcoxon testing to assess differences between disciplines' median values of number of weekly injections and logistic regression to study demographic variables' predictive values (P = .01). General dentists give more injections than do family physicians. Differences existed between disciplines' awareness and use of eight of 10 techniques. Disciplines reported cost and time issues as reasons for not using some techniques. Number of years in practice and age were associated with use of six techniques. Dentists reported feeling greater personal effects of patients' pain and needle anxiety/phobia than did family physicians. Those not using pain-lessening techniques inaccurately identified time and cost as problems, suggesting that respondents may be less familiar with these techniques than otherwise reported. Further study is recommended. Pain reduction techniques for anesthetic injection cost little to implement, are not time liabilities, and can lessen avoidable pain and reduce the incidence of needle phobia.

Review of Uncertainty Reasoning Approaches as Guidance for Maritime and Offshore Safety-Based Assessment

Many different formal techniques have been developed over the past two decades for dealing with uncertain information for decision making. In this paper we review some of the most important ones, i.e., Bayesian theory of probability, Dempster-Shafer theory of evidence, and fuzzy set theory, describe how they work and in what ways they differ from one another, and show their strength and weakness respectively as well as their connection. We also consider hybrid approaches which combine two or more approximate reasoning techniques within a single reasoning framework. These have been proposed to address limitations in the use of individual techniques. The study is intended to provide guidance in the process of developing frameworks for maritime and offshore safety-based decision analysis using different methods for reasoning under uncertainty.

Neurophysiological monitoring during surgical treatment of skull-base tumors and vascular lesions

Various electrophysiological monitoring techniques are available for localizing and protecting cranial nerves and the brain stem during skull-base procedures. Separate neural pathways are used with each method, allowing for the simultaneous monitoring of different cranial nerves and brain stem tracts. Although monitoring of the facial nerve during resection of an acoustic neuroma is considered to be a standard of care, other monitoring techniques, such as tracking motor evoked potentials and visual evoked potentials, have not yet gained wide acceptance with neurosurgeons. This situation is in part attributable to technical factors that create difficulties in interpreting intraoperative changes in these responses. The use of individual techniques is usually based on the surgeon's level of comfort in attacking a given lesion and in his or her perception of the sensitivity and specificity of each type of electrophysiological monitoring.

Technique and system: The spread of Japanese management techniques to developing countries

In this paper a distinction is drawn between the isolated use of individual Japanese management techniques and their adoption in an integrated package as part of a production system. Although the use of individual techniques does confer significant benefits to innovating firms, it is clear from international experience that the major gains arise from systemic application. The central objective of this paper is to explore whether there are obstacles specific to less-developed countries (LDCs) in the systemic application of Japanese management techniques. The major forces driving the adoption of these new management techniques are reviewed, based upon research in Latin America, India and Zimbabwe. Then three major LDC-specific factors affecting systemic adoption are considered—human resources, interfirm cooperation and management.

The potential of medium- and long-term life predictions for high-temperature components in power plants

In the past, short- and medium-term remnant life predictions have been successfully applied on the basis of a limited number of inexpensive but powerful inspection and analytical techniques. These techniques no longer hold for today's needs for medium- or long-term life predictions. For these, the evaluation of the life consumption and the remnant life of piping operated in the creep regime requires the most accurate knowledge possible of the actual component behaviour and the condition of the material. There is a multitude of analytical procedures as well as destructive and nondestructive methods of material testing with widely differing energies expended. The reliability of the individual testing and analytical procedures is established, supported by examples, with the background of many years of experience. The comparison and the assessment of the testing and analytical procedures make it clear that the isolated use of individual techniques, even at great expense, do not necessarily lead to reliable predictions for remnant component life. It is clear, however, that better results are achieved through a careful selection and combination of various testing and analytical techniques, even if less extensive procedures are chosen.

POWER STRATEGIES IN ORGANIZATIONS.

Two studies examined subordinate perceptions fo their own and their supervisors' use of behavior alteration techniques and the relationships between such use and subordinate satisfaction. The results indicated that subordinates seldom use most of the techniques in their interactions with their supervisors, but when they do they favor use of Expert and Self-Esteem approaches. Supervisors were found to use most frequently the techniques labeled Expert, Self-Esteem, Reward from Behavior, Legitimate-Higher Authority, and Personal Responsibility. Strong, positive relationships between supervisor and subordinate use of the individual techniques studied were obtained, suggesting a possible modeling effect within the organization. Almost all of the significant correlations between use of individual techniques and subordinate satisfaction with supervision were negative, suggesting the possibility that increased attempts at behavioral alteration stem from subordinate dissatisfaction or lead to that dissatisfaction.
