With the tremendous expansion of the Internet and devices connecting to computer networks, cyber security has become critical in information protection, data storage and use in the virtual environment. A system for detecting the user behavior in a network is a tool for Security Information and Event Management (SIEM). This technology provides real-time analysis of security alerts generated by applications and hardware networks.Keywords: security, network security, cyber security, SIEM, detection of user's behavior, program for detecting the abnormal behavior of users.I.
5G efficiently uses technologies like network slicing (NS), network function virtualization (NFV), software-defined network (SDN), and multi-access edge computing (MEC). At the same time, embracing these technologies and creating new services opens the network to a new set of security challenges. This paper presents a threat analysis of MEC features. The paper's novelty resides in viewing MEC as common ground for the telco and IT sectors. This paper studies the measures according to ISO/IEC 27001:2022 controls. ISO/IEC 27001 is the most popular standard for information security management systems, with a new version published in 2022.
This paper presents an overview of the current computer network vulnerabilities and exploits, possibilities of monitoring the network traffic, by intercepting and duplicating it, ways of analyzing the monitored traffic in order to better understand and explain the detection of user's behavior.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
