Role of Support Vector Machine, Fuzzy K-Means and Naive Bayes Classification in Intrusion Detection System
An Intrusion can be defined as the access to unauthorised user, a breach in a security, misuse of the information or the system which can be done both internally and externally of the organization. So, Intrusion Detection is basically providing the security or managing the flow of data, information, managing the access of the system to only authorised user. In a network which is widely distributed requires high end security, only authorised user can access the system in a network. So, it requires more than authentication, providing passwords or certificates. An Intrusion Detection system is used to detect and monitor the number of happenings and episode in a network or a system. It will gather the information and analyse that information. If, it finds any unauthorized access or misuse it will detect it as Intrusion and will follow provided instructions. So, If Intrusion is the violation of security, then Detection is the management and taking necessary action against that Intrusion. For detecting any Intrusion in a network or system there are number of techniques which are used and can be developed to prevent.

Implementation of Multilayer cybersecurity based on Intrusion Detection System
Cyber security has become a high priority in Industrial Sector/Automation. Here the dependable operation is to ensure the stable, secure and reliable in power system delivery. By using the Intrusion Detection System framework Obscurity progress can be easily removed. Access control mechanism mainly used to launching the anomalous attacks. This framework provides a hierarchical approach for; integrated security system and comprising distributed IDSs. In a novel SCADA-IDS with whitelists and behavior-based protocol analysis is proposed and it is exemplified in order to detect known and unknown cyber-attacks from inside or outside SCADA systems. Finally, our proposed SCADA-IDS is implemented and it is successfully validated through a series of scenarios performed in a SCADA-specific test bed developed to replicate cyber-attacks against a substation LAN. From the perspective of SCADA system operators, the lack of openly available test dataset is a bottleneck, to compare the performance and accuracy of proposed solutions. However, for the research in the community to progress, such a large dataset would be valuable. The propose system will to creating a new dataset to mitigate vulnerable attack from cyber-crime to save the higher level records and system.

Feature Selection in UNSW-NB15 and KDDCUPβ99 datasets
Machine learning and data mining techniques have been widely used in order to improve network intrusion detection in recent years. These techniques make it possible to automate anomaly detection in network traffics. One of the major problems that researchers are facing is the lack of published data available for research purposes. The KDDβ99 dataset was used by researchers for over a decade even though this dataset was suffering from some reported shortcomings and it was criticized by few researchers. In 2009, Tavallaee M. et al. proposed a new dataset (NSL-KDD) extracted from the KDDβ99 dataset in order to improve the dataset where it can be used for carrying out research in anomaly detection. The UNSW-NB15 dataset is the latest published dataset which was created in 2015 for research purposes in intrusion detection. This research is analysing the features included in the UNSW-NB15 dataset by employing machine learning techniques and exploring significant features (curse of high dimensionality) by which intrusion detection can be improved in network systems. Therefore, the existing irrelevant and redundant features are omitted from the dataset resulting not only faster training and testing process but also less resource consumption while maintaining high detection rates. A subset of features is proposed in this study and the findings are compared with the previous work in relation to features selection in the KDDβ99 dataset

The research aims to develop the technique for an automated detection of information system assets and comparative assessment of their criticality for farther security analysis of the target infrastructure. The assets are all information and technology objects of the target infrastructure. The size, heterogeneity, complexity of interconnections, distribution and constant modification of the modern information systems complicate this task. An automated and adaptive determination of information and technology assets and connections between them based on the determination of the static and dynamic objects of the initially uncertain infrastructure is rather challenging problem. The paper proposes dynamic model of connections between objects of the target infrastructure and the technique for its building based on the event correlation approach. The developed technique is based on the statistical analysis of the empirical data on the system events. The technique allows determining main types of analysed infrastructure, their characteristics and hierarchy. The hierarchy is constructed considering the frequency of objects use, and as the result represents their relative criticality for the system operation. For the listed goals the indexes are introduced that determine belonging of properties to the same type, joint use of the properties, as well as dynamic indexes that characterize the variability of properties relative to each other. The resulting model is used for the initial comparative assessment of criticality for the system objects. The paper describes the input data, the developed models and proposed technique for the assets detection and comparison of their criticality. The experiments that demonstrate an application of the developed technique on the example of analyzing security logs of Windows operating system are provided.Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ Π·Π°ΠΊΠ»ΡΡΠ°Π΅ΡΡΡ Π² ΡΠ°Π·ΡΠ°Π±ΠΎΡΠΊΠ΅ ΠΌΠ΅ΡΠΎΠ΄ΠΈΠΊΠΈ Π°Π²ΡΠΎΠΌΠ°ΡΠΈΠ·ΠΈΡΠΎΠ²Π°Π½Π½ΠΎΠ³ΠΎ Π²ΡΠ΄Π΅Π»Π΅Π½ΠΈΡ Π°ΠΊΡΠΈΠ²ΠΎΠ² ΠΈΠ½ΡΠΎΡΠΌΠ°ΡΠΈΠΎΠ½Π½ΠΎΠΉ ΡΠΈΡΡΠ΅ΠΌΡ ΠΈ ΡΡΠ°Π²Π½ΠΈΡΠ΅Π»ΡΠ½ΠΎΠΉ ΠΎΡΠ΅Π½ΠΊΠΈ ΡΡΠΎΠ²Π½Ρ ΠΈΡ

Multi-Attribute SCADA-Specific Intrusion Detection System for Power Networks
The increased interconnectivity and complexity of supervisory control and data acquisition (SCADA) systems in power system networks has exposed the systems to a multitude of potential vulnerabilities. In this paper, we present a novel approach for a next-generation SCADA-specific intrusion detection system (IDS). The proposed system analyzes multiple attributes in order to provide a comprehensive solution that is able to mitigate varied cyber-attack threats. The multiattribute IDS comprises a heterogeneous white list and behavior-based concept in order to make SCADA cybersystems more secure. This paper also proposes a multilayer cyber-security framework based on IDS for protecting SCADA cybersecurity in smart grids without compromising the availability of normal data. In addition, this paper presents a SCADA-specific cybersecurity testbed to investigate simulated attacks, which has been used in this paper to validate the proposed approach
Evaluation of DoS attacks on Commercial Wi-Fi-Based UAVs
One of the biggest challenges for the use of Unmanned Aerial Vehicles (UAVs) in large-scale real-world applications is security. Β However, most of research projects related to robotics does not discuss security issues, moving on directly to studying classical problems (i.e., perception, control, planning). This paper evaluates the effects of availability issues (Denial of Service attacks) in two commonly used commercially available UAVs (AR.Drone 2.0 and 3DR SOLO). Denial of Service (DoS) attacks are made while the vehicles are navigating, simulating common conditions found both by the general public and in a research scenario. Experiments show how effective such attacks are and demonstrate actual security breaches that create specific vulnerabilities. The results indicate that both studied UAVs are susceptible to several types of DoS attacks which can critically influence the performance of UAVs during navigation, including a decrease in camera functionality, drops in telemetry feedback and lack of response to remote control commands. We also present a tool that can be used as a failsafe mechanism to alert the user when a drone is reaching out a determined flight limit range, avoiding availability issues

An Intrusion Detection System (IDS) is capable to detect unauthorized intrusions into computer systems and networks by looking for signatures of known attacks or deviations of normal activity. However, accuracy performance is one of the issues in IDS application. Meanwhile, classification is one of techniques in data mining employed to increase IDS performance. In order to improve classification performance problem, feature selection and discretization algorithm are crucial in selecting relevant attributes that could improve classification performance. Discretization algorithms have been recently proposed; however, those algorithms of discretizer are only capable to handle categorical attributes and cannot deal with numerical attributes. In fact, it is difficult to determine the needed number of intervals and their width. Thus, to deal with huge dataset, data mining technique can be improved by introducing discretization algorithm to increase classification performance. The generation of rule is considered a crucial process in data mining and the generated rules are in a huge number. Therefore,it is dreadful to determine important and relevant rules for the next process . As a result, the aim of the study is to improve classification performance in terms of accuracy, detection rate and false positive alarm rate decreased for IDS application. Henceforth, to achieve the aim, current research work proposed an enhancement of discretization algorithm based on Binning Discretization in RST to improve classification performance and to enhance the strategy of generation rules in RST to improve classification performance. Both enhancements were evaluated in terms of accuracy, false positive alarm and detection rate against state-of-the-practice dataset (KDD Cup 99 dataset) in IDS application. Several discretization algorithms such Equal Frequency Binning, Entropy/MDL, NaΓ―ve and proposed discretization were analysed and compared in the study. Experimental results show the proposed technique increases accuracy classification percentage up to 99.95%; and the minimum number of bins determine good discretization algorithm. Consequently, attack detection rate increases and false positive alarm rate minimizes. In particular, the proposed algorithm obtains satisfactory compromise between the number of cuts and classification accuracy
