To cope with these types of attacks, an effective intrusion detection system that can handle unexpected and previously undetected attacks is required. It is recognized that traditional mechanisms for detecting these attacks are no longer sufficient to deal with the increasing and diverse attacks. IDS can be categorized according to their detection methodology, such as signature-based IDS, anomaly-based IDS, and stateful protocol analysis. Intrusion detection systems (IDSs) are an important part of the defense mechanisms through which continuous monitoring of the system is performed. With the increasing use of the Internet, attacks on networks are also on the rise, with denial of service (DoS) being the most common example of a network attack. The results show that the stacking-based ensemble approach is the most promising and achieves the highest weighted F1-score of 98.24%. ![]() Several different machine learning approaches are applied to the features extracted from the traffic data, and their performance is compared. Key flow features are extracted using cicflowmeter for each attack and are evaluated to analyze their behavior. Various attack scenarios were implemented along with benign user traffic on the network topology created using graphical network simulator-3 (GNS-3). Then, we propose a stacking-based ensemble approach that outperforms the overall state of the art for NIDS. In this research, we first identify some limitations of the legacy NIDS datasets, including a recent CICIDS2017 dataset, which lead us to develop our novel dataset, CIPMAIDS2023-1. This research aims to address some of the issues faced by anomaly-based network intrusion detection systems. Network intrusion detection systems (NIDSs), which are used to detect malicious or anomalous network traffic, are an integral part of network defense. ONOS noted the CORD initiative is designed to “provide economies of scale and agility of cloud computing to the telco central office by leveraging infrastructure constructed from commodity building blocks” using software-defined networking, network functions virtualization and cloud technologies.The increasing demand for communication between networked devices connected either through an intranet or the internet increases the need for a reliable and accurate network defense mechanism. ![]() The CORD platform has seen carrier interest from the likes of AT&T, Verizon Communications and SK Telecom, among others. The Linux Foundation-hosted organization targets service providers with significant recent work around its central office re-architected as a datacenter initiative. “ONOS is the only SDN control plane that can support both disruptive and incremental SDN for service providers.” “Thanks to the broad range of service providers, industry leaders and developers actively contributing to and developing ONOS, the project is promoting network disruption through open source software and whitebox switches, while providing incremental SDN delivery to support migration and evolve carrier networks,” said Bill Snow, VP of engineering at ON.Lab. Collaborators on the latest release included AT&T, the Electronics Telecommunications and Research Institute, Fujitsu and Huawei. ONOS said the Goldeneye release includes advances such as improved adaptive flow monitoring and selective DPI from ETRI, claimed to provide lower overhead flow monitoring and Yang tool chain support from Huawei integration of northbound intent subsystem with the Flow objective subsystem a six-times improvement in core performance to support consistent distributed operations and southbound improvements to Cisco IOS NetConf and Yang tool chain. The Open Network Lab’s Open Network Operating System project unveiled its seventh release targeting a software-defined networking operating system, dubbed “Goldeneye.” ON.Lab states ONOS Goldeneye release set to further support service provider SDN and NFV deployment plans
