Despite the large volume of research conducted in the field of intrusion detection, finding a perfect solution of intrusion detection systems for critical applications is still a major challenge. This is mainly due to the continuous emergence of security threats which can bypass the outdated intrusion detection systems. The main objective of this paper is to propose an adaptive design of intrusion detection systems on the basis of Extreme Learning Machines. The proposed system offers the capability of detecting known and novel attacks and being updated according to new trends of data patterns provided by security experts in a cost-effective manner. 相似文献

This paper addresses L2 observer-based fault detection issues for a class of nonlinear systems in the presence of parametric and dynamic uncertainties, respectively. To this end, three different types of uncertain affine nonlinear system models studied in this paper are described first. Then, the integrated design schemes of L2 observer-based fault detection systems are derived with the aid of Hamilton–Jacobi inequalities (HJIs), respectively. Numerical examples are also provided in the end to demonstrate the effectiveness of the proposed results. 相似文献

This paper proposes a roadmap for how privacy leakages from outsourced managed security services using intrusion detection systems can be controlled. The paper first analyses the risk of leaking private or confidential information from signature-based intrusion detection systems. It then discusses how the situation can be improved by developing adequate privacy enforcement methods and privacy leakage metrics in order to control and reduce the leakage of private and confidential information over time. Such metrics should allow for quantifying how much information that is leaking, where these information leakages are, as well as showing what these leakages mean. This includes adding enforcement mechanisms ensuring that operation on sensitive information is transparent and auditable. The data controller or external quality assurance organisations can then verify or certify that the security operation operates in a privacy friendly manner. The roadmap furthermore outlines how privacy-enhanced intrusion detection systems should be implemented by initially providing privacy-enhanced alarm handling and then gradually extending support for privacy enhancing operation to other areas like digital forensics, exchange of threat information and big data analytics based attack detection. 相似文献

Machine learning applications must continually utilize label information from the data stream to detect concept drift and adapt to the dynamic behavior. Due to the computational expensiveness of label information, it is impractical to assume that the data stream is fully labeled. Therefore, much research focusing on semi-supervised concept drift detection has been proposed. Despite the large research effort in the literature, there is a lack of analysis on the information resources required with the achievable concept drift detection accuracy. Hence, this paper aims to answer the unexplored research question of “How many labeled samples are required to detect concept drift accurately?” by proposing an analytical framework to analyze and estimate the information resources required to detect concept drift accurately. Specifically, this paper disintegrates the distribution-based concept drift detection task into a learning task and a dissimilarity measurement task for independent analyses. The analyses results are then correlated to estimate the required number of labels within a set of data samples to detect concept drift accurately. The proximity of the information resources estimation is evaluated empirically, where the results suggest that the estimation is accurate with high amount of information resources provided. Additionally, estimation results of a state-of-the-art method and a benchmark data set are reported to show the applicability of the estimation by proposed analytical framework within benchmarked environments. In general, the estimation from the proposed analytical framework can serve as guidance in designing systems with limited information resources. This paper also hopes to assist in identifying research gaps and inspiring new research ideas regarding the analysis of the amount of information resources required for accurate concept drift detection. 相似文献

根据问卷调查的数据对我国公共农业科研机构的科研激励制度进行了描述,讨论了科学家对公共农业科研机构利益目标的认知,并从职称晋升、学术奖励、绩效薪酬等方面分析了现行科研激励制度对科学家的影响。研究表明争取科研经费是得到样本科学家普遍认同的公共农业科研机构利益目标,为农户服务则被样本科学家认为是公共农业科研机构最重要的价值使命。同时现行科研激励制度并没有有效促进科学家学术水平的提高,在学术评审中“打招呼”等潜规则的存在则严重影响了科学家的学术信心。 相似文献

Critical research is becoming increasingly accepted as a valid approach to research in information systems. It is deemed to be particularly suitable for situations where researchers want to address conspicuous injustice, such as in areas of development or the digital divide. Critical research in information systems (CRIS), I will argue, is a possible approach to some of the ethical problems arising in the context of information and communication technology (ICT). It can be sensitive to the question of culture and therefore suitable for researching cross-cultural ethical questions in ICT. It is often unclear, however, what exactly critical research stands for and to what extent critical approaches are applicable across cultural boundaries. This paper will address these problems by proposing a definition of critical research as focused on changing the status quo and aiming for emancipation. It will then look at the question whether different cultures are compatible and comparable and what the role of culture in research on information systems is. The paper will then return to the question whether the critical intention to emancipate and empower humans is an expression of cultural imperialism or whether there are valid ways of promoting emancipation across cultural divides. 相似文献
