Low-speed internet can negatively impact incident response by causing delayed detection, ineffective response, poor collaboration, inaccurate analysis, and increased risk. Slow internet speeds can delay the receipt and analysis of data, making it difficult for security teams to access the relevant information and take action, leading to a fragmented and inadequate response. All of these factors can increase the risk of data breaches and other security incidents and their impact on IoT-enabled communication. This study combines virtual network function (VNF) technology with software -defined networking (SDN) called virtual network function software-defined networking (VNFSDN). The adoption of the VNFSDN approach has the potential to enhance network security and efficiency while reducing the risk of cyberattacks. This approach supports IoT devices that can analyze large volumes of data in real time. The proposed VNFSDN can dynamically adapt to changing security requirements and network conditions for IoT devices. VNFSDN uses threat filtration and threat-capturing and decision-driven algorithms to minimize cyber risks for IoT devices and enhance network performance. Additionally, the integrity of IoT devices is safeguarded by addressing the three risk categories of data manipulation, insertion, and deletion. Furthermore, the prioritized delegated proof of stake (PDPoS) consensus variant is integrated with VNFSDN to combat attacks. This variant addresses the scalability issue of blockchain technology by providing a safe and adaptable environment for IoT devices that can quickly be scaled up and down to pull together the changing demands of the organization, allowing IoT devices to efficiently utilize resources. The PDPoS variant provides flexibility to IoT devices to proactively respond to potential security threats, preventing or mitigating the impact of cyberattacks. The proposed VNFSDN dynamically adapts to the changing security requirements and network conditions, improving network resiliency and enabling proactive threat detection. Finally, we compare the proposed VNFSDN to existing state-of-the-art approaches. According to the results, the proposed VNFSDN has a 0.08 ms minimum response time, a 2% packet loss rate, 99.5% network availability, a 99.36% threat detection rate, and a 99.77% detection accuracy with 1% malicious nodes.

The paper presents a Markov model of the basic scheme of interaction between project participants. A Markov chain has been identified to describe a specific project, based on the determination of a set of transition probabilities unique for each project. This allows you to customize the Markov chain to reflect the properties of a particular project. Using the developed Markov model, the sensitivity of the system to a change in one of the main parameters, the level of competence of the project manager and the project team as a whole, was assessed. The mathematical description of the project model by Markov chains allows modeling the quantitative parameters of projects, namely, changes in the probabilities of system states depending on the number of project steps.

In this article, proposes a model of data integration in which should be supported a unified view of heterogeneous data sources, management of integrity constraints, managing the execution of operations of data manipulation and query, reconciliation of data from different sources, the ability to extend and customize the new data sources. The proposed approach to integration is based on the recursive decomposition of data sources where each source data is divided sequentially into atomic data items, wherein for each level of the recursive nesting data and their descriptions are represented uniformly. Such model enables the integration of different data sources at any level by setting arbitrary links between elements of the scheme, integrity constraints and allowed operations.

The proposed models of representations of event logs which are formed by the information system e-license, further Information System (IS) provides the issuance of licenses and permits. When process management generated event logs reflect the steps involved in business processes in the system and in functional management — implementation of certain functions of IS. The proposed models of log create an opportunity to build new models of business processes with process mining techniques based on the processing of structured event logs.
