The purpose of the article. The study describes video clips of Ukrainian pop-rockperformers, which embody a variety of stage images covering a wide range of socially significantissues. The methodology consists in the application of analytical and contextual methods, whichmade it possible to characterize the most significant and relevant topics in the video clips ofcontemporary Ukrainian pop-rock performers. Scientific novelty of the work is that for the firsttime in Ukrainian science video clips were considered in the works of domestic performers in thestyle of pop rock and the main ways of representing their images in compositions were determinedon topical and socially significant topics. Conclusions. The theme of love and socially significantissues are most popular in the works of Ukrainian pop-rock performers. In the video of worksdedicated to the theme of love, the performer is identified with the lyrical hero, while the plotdecision in each work varies depending on the director’s plan, which is repelled from the text of thesong. The subject of love often coincides with the images of «beautiful life» embodied in thecorresponding scenic images; it, according to the aesthetics of rock music, can be interpreted as acontrast to the true reality. Social issues are raised primarily in lyrics, but it can be amplified bythe video, expanding to a separate plot.Key words: contemporary popular Ukrainian music, pop rock, video clip, glamor, socialissues

The purpose of the article. The study describes the principles of supporting Ukraine during the war in the musical space and the place of rock music in the development of patriotic upsurge through concert performances within Ukraine and on the world stage. The research methodology consists in the application of analytical and historical-cultural methods, which made it possible to identify and characterise the foundations of the transformational processes of rock music on the example of the activities of musical bands and performers. The scientific novelty of the study lies in the fact that for the first time in the Ukrainian scientific perspective, Ukrainian and Western rock music is defined in the light of the support of the Ukrainian people during the war and “national”, “international” and “urban” cultural codes are identified in the work of rock bands and performers. Conclusions. Rock music has never stood aside from acute social topics, because the emergence of new directions in rock has always reflected the mood of the world order, which certainly manifested itself in music, lyrics, video clips, as well as in stage productions. The work determined the general characteristics of the transformational processes of rock music; features of Ukrainian and Western rock music during the war – Ukrainian musical lexemes, characteristic Ukrainian melos and disclosure of the philosophical content characteristic of Ukraine during the war. Emphasis is placed on the manifestation of “national”, “international” and “urban” cultural codes in the work of rock bands during the war in Ukraine. A super-important national component was discovered through the use of the Ukrainian language and the use of elements of the national musical language. Among the rock bands, the following features were identified: the use of Ukrainian symbols, calls for an end to the war, communication with a foreign listener through English, holistic support for the Ukrainian people, and the focus of concert performances on specific locations with an urban accent. Key words: rock band, rock music, sound, pop rock, cultural code.

The availability of critical infrastructure through cyberspace makes national security dependent on the degree of its security. Critical infrastructure is a set of automated management systems, which provide the interaction of information and telecommunications networks that solve problems of public administration, defense, security and law enforcement, and others. The protection of critical infrastructure directly depends on the possession of the relevant structures of new weapons, the degree of its effectiveness, methods of use and means of protection against the same weapons of the enemy. It is necessary to address the issue of effective confrontation in cyberspace. The analysis of problems in the development of methods for assessing the functional stability of critical infrastructure in cyber confrontation requires the definition of basic methods and criteria that can be used in Ukraine to assess the stability of critical infrastructure. Cyber weapons, which carry out destructive information effects, are not weapons in the classical sense, because they do not physically damage the object of attack, but translate its information and automated control systems into a crisis mode of operation. The process of counteraction of two or more parties, in this form, is a cyber confrontation that is realized using a common common resource - the global information space. In the process of critical infrastructure management, cyber confrontation imposes additional requirements to ensure the sustainable operation of critical infrastructure. Stability is an integral property that is inextricably linked to the operating environment. Cyber resilience is an integrated indicator and is determined by cyber reliability, which reflects the ability to perform its tasks in a complex critical infrastructure management system in the context of information destructive influences.

The problem of information security in wireless sensor networks is considered in this paper. An analysis of existing recommendations for information security in wireless sensor networks. It was found that one of the key problems of information security is the hardware limitations of the sensor nodes of the network. It is substantiated that the use of more complex cryptographic protection mechanisms will increase the load on the network. Safety requirements and their description are given. The main groups and types of information security threats in wireless sensor networks are considered. The classification of attacks and protection of wireless sensor networks according to the OSI model is presented. The existing solutions for information security are considered and analyzed. The shortcomings and vulnerabilities of the considered solutions are revealed. The method of public key cryptography is considered, the main advantages and disadvantages of this method are revealed. The analysis and comparison of ECC and RSA encryption methods are carried out. It is substantiated that the use of ECC in wireless sensor networks is more efficient than RSA. The method of cryptography with a symmetric key is considered, the main advantages and disadvantages of this method are indicated. It was found that cryptographic methods using a symmetric key are more priority for use in wireless sensor networks. Cryptographic key management protocols in wireless sensor networks are considered. The classification of key management protocols is given. Secure routing protocols are considered. The classification of secure routing protocols is given. Methods of secure data aggregation are considered. Contradictions between the requirements for confidentiality and data aggregation have been revealed. The method of intrusion detection is considered, the main advantages and disadvantages of this method are revealed. The results of this work should be used in the design of wireless sensor networks.
