Signature-based Intrusion Detection Hardware-Software Complex

Abstract

Nowadays hackers are able to find many software vulnerabilities, which can be exploited for malicious purposes such as to destroy the operating system, to steal users' private data, to demand a ransom not to affect the data and retain their validity. The majority of attacks use an Internet connection; therefore, the efforts should be directed to the way in which data packets are transmitted. The hardware-software complex, which is the main subject of the presented research, serves as a firewall for the devices on one subnetwork with access to the Internet, simultaneously analysing and filtering both downstream and upstream traffic at packet level, resolving scumware and securing the perimeter of each device in the subnet. The concept and the architecture of the developed hardware-software complex are described. The implemented complex will not allow malicious traffic to pass through, providing protection of all endpoint devices in a subnetwork. The experimental results of malware detected are presented, and the security related metrics are evaluated.

Tools for Analyzing Signature-Based Hardware Solutions for Cyber Security Systems

“…The principle of construction of RC of EF of a digital scheme consists in calculating hardware costs of all kinds, namely LUTs, flip-flops, memory blocks, etc., and reducing them to a single unit of measurement according to formula (1). The TC of EF is calculated according to theoretical information on the delay of signal propagation in the component parts of the circuits, taking into account their interconnections.…”

“…In contrast to traditional fields of application of information systems, attacks on critical infrastructure facilities, which include energy companies, can lead to catastrophic consequences. Therefore, methods of detecting malicious activity, based on the use of signatures that ensure mathematically strict recognition, do not lose their relevance in the creation of cybersecurity systems, such as network intrusion detection systems (NIDS), antiviruses, anti-worm systems and spam filters [1,2].…”

Advertising in the Modern Urban Space: A Socio-Philosophical Analysis

“…Changes in the socio-cultural space under these conditions both determine the quality and lifestyle of residents, the image of the city, and affect the psychophysiological health of consumers of advertising. Thus, scientists are faced with the problem of understanding the processes of totalization of the presence of advertising in the modern urban [19]; Maksym Karpovets made a philosophical understanding of the city as a specific, complex and ambiguous phenomenon of culture and as a world of human existence [9]; Volodymyr Stetsenko revealed the content and forms of integration of information and advertising objects into the urban space [14]; Anna Chmil analyzed the current state of society, the characteristic feature of which is the loss of a sense of reality, the implementation of the principle of simulation and hyperreality of codes that begin to control people [17]. The researches of the Russian philosopher Galina Gornova devoted to the problems of urban identity are meaningful [8].…”
