Документ Відкритий доступ Construction of Proactive Monitoring Model using Forecasting Techniques in the SCOM Software Complex(Igor Sikorsky Kyiv Polytechnic Institute, 2022) Soldatova, Kateryna; Nosok, SvitlanaThe majority of companies depend on their information systems, the stability of infrastructure operations and the failover of computing resources. Various monitoring tools are mostly used to automate the benchmarking process of company. The company that has a large distributed infrastructure should pay close attention to this process, as it makes the state of operations difficult to maintain, and increases the probability of the loss of functionality for errors or even shutdown of some servers. The one of solutions is reactive monitoring. Reactive monitoring is a technique where system administrators use monitoring tools to continuously collect data that determine the active and current status of information system environment. Measurements obtained from real-time monitoring tools illustrate the performance data of current information environment. However, if we discuss the main metrics of system resources, such as the level of processor load, RAM or disk usage, their change can be quite fast. And for servers that are responsible for critical functions, the problem of full resource usage is important. This problem can be solved with proactive monitoring. The purpose of this article is to construct the proactive monitoring model with time series forecasting hybrid method for the resources load. The final solution will be used in the management pack of software complex System Center Operations Manager (SCOM). The forecasting methods such as Least squares, SMA and EMA were considered in this work.Документ Відкритий доступ Software security risk management in DEVOPS methodology(Igor Sikorsky Kyiv Polytechnic Institute, 2021) Kolisnichenko, Olga; Kolomytsev, Mykhailo; Nosok, SvitlanaIt’s impossible to talk about cloud technologies, modern applications and, in general, digital transformation, and not to mention security. The same applies to software development, in particular the DevOps methodology. DevOps is a software development methodology that focuses on communication, integration, and collaboration between IT professionals ensuring rapid product deployment. DevOps practice reflects the idea of continuous improvement and automation. Many practices are designed for one or more stages of the development cycle. Three hundred hours spent on software development can be wasted in just 30 seconds, if only one defect during operation is detected. This, subsequently, can ruin reputation of the whole product, and as a result there will be no choice but to simply remove it from the market. And this establishes the importance and necessity of quality control. To ensure quality of software products during development risk management should be used at every stage of the DevOps lifecycle. Implementing DevOps without paying attention to security will definitely increase risks of attacks. Risk is the occurrence of an uncertain event that positively or negatively affects measured criteria of project success. These can be events that have happened in the past or current events, or something that may happen in the future. These uncertain events can affect target, business, technical and qualitative objectives of the project.
