Their corresponding groups, namely: Interface, IP, TCP and ICMP. Records, where each record consists of 34 MIB variables, which are categorized into
Involving six types of DoS attacks and Brute Force attack. Then we use this data from an SNMP agent by means of real-life experiments Information Base (MIB) based mechanism capturing realistic SNMP-MIB statisticalĭata.
Protocol (SNMP) for network anomaly detection. Our systematic approach involves the investigation of Simple Network Management This paper, we identify the important requirements to generate effective dataset and weĪlso identify important attack scenarios and the method of injecting them in such data. To overcome such shortcoming of the existing datasets, in Realistic datasets is very important as it allows for accurate and appropriate evaluation The datasets in hand depend on simulated-based approaches, which cannot represent theĮxact and the nature of network intrusion and anomaly scenarios. Researchers suffer from the lack of real-life datasets. Therefore, the intrusionĭetection and network anomalies become very critical tasks in the field of network For example,ĭenial of Service (DoS) flooding attacks have recently become attractive to attackers,Īnd these have posed devastating threats to network services. Among many security issues, network attack is a major one. The enormous growth in computer networks and in Internet usage in recent years,Ĭombined with the growth in the amount of data exchanged over networks, have shownĪn exponential increase in the amount of malicious and mysterious threats to computer The early detection of multi-step attacks also allows the administrator to take the necessary actions in time, to mitigate the potential threats. According to these results, the IDS built upon the FRI based fuzzy automaton could be a useful device for detecting multi-step attacks, even in cases when the intrusion state transition rule-based is incomplete.
Furthermore, in the studied examples, the suggested method was able not only to detect but also early detect the multi-step attack in stages, where the planned attack is not fully elaborated and hence less harmful. On the multi-step attack benchmark dataset introduced in this paper, the proposed detection mechanism was able to achieve 97.836% detection rate. In the suggested model, the intrusion definition state transition rule-base is defined using an open source fuzzy declarative language. In that respect, the FRI method instruments the fuzzy automaton to be able to act on a not fully defined state transition rule-base, by offering interpolated conclusion even for situations which are not explicitly defined. The goal of this paper is to introduce a novel detection mechanism for multi-step attacks built upon Fuzzy Rule Interpolation (FRI) based fuzzy automaton. Currently, the largest proportion of attacks performed, are multi-step attacks. However, attack techniques have changed in recent years. These types of attacks can be detected using either a common convincing threshold or by pre-defined rules. The typical IDS detection mechanisms are targeted to detect and prevent single-stage attacks. This integration allows a discretely defined state-machine to act on continuous universes and handle uncertainty in applications like Intrusion Detection Systems (IDS). The integration of a fuzzy system and automaton theory can form the concept of fuzzy automaton. The experiment result indicates that the port scan mitigation implementation on UTM helps reducing the load on the UTM device and reduces network congestion effectively. To address this lack of knowledge, this experiment is carried out in fully controlled test bed environment wherein a set of varieties of attack can be simulated and impact of attack(s) is analyzed and appropriate mitigation technique is suggested to mitigate the port scan attack. There have been relatively few empirical studies done for port scan related attacks and those that do exist may no longer reflect the impact of such attacks on the functionalities of the UTM/network device and on the network. In previous work, the port scan attack is considered as precursors to an attack and the target was to provide the mitigation technique for the particular port scan attack. There is a need of continuous evaluation of the security of a network and enhancement of the network attack detection system, which will be able to detect different attacks along with the characteristics of the attacks. Along with the growth of the computer system and networks, the mysterious and malicious threats and attacks on the computer systems are also increasing exponentially.
