This article explores these trends and advanced models of pre-service learning. Inputs are converted into words or contextual embeddings that serve as inputs to encoders and decoders. The corpus of the author's publications over the past six years is used as the object of the research. The main methods of research are the analysis of scientific literature, prototyping, and experimental use of systems in the direction of research. Speech recognition players are divided into players with huge computing resources for whom training on large unlabeled data is a common procedure and players who are focused on training small local speech recognition models on pre-labeled audio data due to a lack of resources. Approaches and frameworks for working with unlabeled data and limited computing resources are almost not present, and methods based on iterative training are not developed and require scientific efforts for development. The research aims to develop methods of iterative training on unlabeled audio data to obtain productively ready speech recognition models with greater accuracy and limited resources. A separate block proposes methods of data preparation for use in training speech recognition systems and a pipeline for automatic training of speech recognition systems using pseudo marking of audio data. The prototype and solution of a real business problem of emotion detection demonstrate the capabilities and limitations of owl recognition systems and emotional states. With the use of the proposed methods of pseudo-labeling, it is possible to obtain recognition accuracy close to the market leaders without significant investment in computing resources, and for languages with a small amount of open data, it can even be surpassed.","PeriodicalId":198390,"journal":{"name":"Cybersecurity: Education, Science, Technique","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116125550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The possibilities of using network protocols and application of DPI systems are investigated in the article. The analysis of the problem made it possible to identify vulnerabilities in the DNS protocol, which is based on the UDP protocol. These vulnerabilities include spoofing, interception, and traffic tethering. Also on the basis of the analysis of methods of protection of DNS traffic from interference, the authors substantiate and define the following: 1) all DNS queries are transmitted in the open; 2) existing approaches to traffic protection do not use encryption and, consequently, do not ensure the confidentiality of information; 3) there is only confirmation of the authenticity of the records. The authors have created a summary table, which identifies reliable methods of protecting DNS traffic. The authors propose the development of a full-fledged local proxy server to provide DNS traffic that can access trusted public DNS resolvers using doh and dot protocols. To understand the principles of protocol interaction, we developed our own local implementation of the main components of the network, which are most often dealt with by network users, namely: 1) web server; 2) DNS server; 3) server providing cryptographic protection and hiding open requests. The practical value of the obtained results lies in the software implementation of methods to protect traffic from DPI systems in Visual Studio Code by using the Python 3.8 programming language, which allows to provide cryptographic protection of traffic. The proposed solution of the local proxying server can be improved in the future by introducing local caching with the addition of the ability to create rules for certain domains and their subdomains. The implemented test doh server can be deployed on a trusted dedicated server outside of possible filter equipment installation points. This implementation will allow you to fully control your own traffic for resolving domain names. The authors further plan a number of scientific and technical solutions to develop and implement effective methods, tools to meet the requirements, principles and approaches to cyber security and traffic protection from interference by DPI systems in experimental computer systems and networks.","PeriodicalId":198390,"journal":{"name":"Cybersecurity: Education, Science, Technique","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124925663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Widely spread problems like excessive amounts of false positive alerts or not absolutely accurate configuration of the correlation rules may lead to situation where an attacker is able to trigger an undesired state of the monitoring system. We’ve find three potential vectors for evasion the SIEM powered SOCs monitoring. The first vector grounds on mechanisms used to collect event data – log collectors: the malfunctioning SIEM state can be achieved with generating and submitting the bogus event data to the processing party like SIEM. Fake data flow may cause generation of mistaken alerts which can confuse the analytics stuff. The second vector employs some of the attacker’s knowledge about actual SIEM configuration – exploitation of correlation rule flaws. Taking into account the fact that correlation rules are mostly hand-written, they are prone to some logic flaws – certain detection rules may not be triggered by all of the malicious attack indicators. An attacker with knowledge about that feature may fulfill the unrecorded conditions and trick the SIEM to treat the attack flow as benign activity. The last researched vector is based on redundantly sensitive detection rules which produce a lot of false positive alarms but are not removed. An attacker may trigger the malfunctioning alarm continuously to distract the analytics stuff and perform its actions under the cover of noise. Those discussed vectors are derived from analysis of the actual SIEM installations and SOC processes used as best practices. We have no actual indicators that those attacks are carried out “in wild” at the moment of issuing of this article, but it is highly probable that those tactics may be used in the future. The purpose of this research is to highlight the possible risks for the security operation centers connected with actual processes and practices used in industry and to develop the remediation strategy in perspective.","PeriodicalId":198390,"journal":{"name":"Cybersecurity: Education, Science, Technique","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124306223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One key challenge is the constantly evolving nature of ransomware attacks, which requires systems to be regularly updated and adapted to stay effective. Another challenge is the need for systems to be able to distinguish between legitimate and malicious software, as well as different types of ransomware. To address these challenges, the paper proposes a number of functional and non-functional requirements for ransomware detection and counteraction systems. These include the ability to detect and respond to attacks in real time or close to it, the ability to analyze and classify different types of ransomware, and the ability to integrate with other security systems and tools. Additionally, non-functional requirements such as scalability, performance, and security should also be considered.The paper also presents a detailed analysis of the different types of ransomware detection and counteraction systems currently available, including intrusion detection systems (IDS), endpoint detection and response (EDR), and modern antiviruses. It also provides a comparison of their strengths and weaknesses, and a classification of existing solutions according to their similarity. Finally, the paper presents an evaluation algorithm for assessing the quality of products for detecting and countering ransomware. The algorithm is based on a set of functional and non-functional requirements and is designed to provide a comprehensive and objective assessment of the capabilities of different systems. The algorithm is validated through a series of tests and experiments, which demonstrate its effectiveness in identifying the best solutions for detecting and countering ransomware.

Analysis of publications confirms the growing needs and interest of software developers in the development of not only technical skills, but also social (behavioral) competencies for effective and efficient performance of professional activities. During interviews with recruits, IT companies try to find out not only the level of hard skills, but also the presence of a set of soft skills. Unlike hard skills, soft skills are the common language of empathy, cooperation, and well-being of people in the workplace. They should be considered holistically because they can change in accordance with changes in a person's life. They form the stability and at the same time flexibility of the team, which ultimately affects the success of the company. Each specific company itself defines its soft skills model as a set of competencies necessary for successful work in it to achieve its strategic goals. Currently, there is no well-defined, established, generally accepted list of soft skills for software developers. In the work, an analysis of numerous publications from the IT company was carried out and a list of soft skills, most important for software developers, considering the specifics of communication skills of the relevant industry, was formed. Communication, teamwork, time management, admitting mistakes, empathy, emotional intelligence, patience, adaptability, creativity, leadership, problem solving and interpersonal skills are the main soft skills that a software developer needs to develop to successfully solve his professional tasks in a team, significantly improve their productivity and increase their overall job satisfaction. The article also examines key difficulties in the formation of relevant soft skills and ways to overcome them.

The protocol defines the way to integrate blockchain technology and web-of-trust concepts to create a decentralized public key infrastructure with easy user ID management. The essence of the scheme is to differentiate the entire infrastructure into 2 levels: the level of certification authorities (service providers) that jointly keep track of events related to user certificates; and the level of end users, systems and applications. During creating, updating, and revoking certificates, higher-level members reach a consensus on the confirmation of transactions associated with them, which ensures a higher level of validity of the certificates and synchronization of their status between certification centers. In turn, lower-level members do not need to perform complex verification procedures for a corresponding certificate: unlike the classic X.509 architecture and web-of-trust approach, the maximum number of checks in a chain can be two. An important feature of such a system is its ability to refuse certification centers: in the case of failure and / or compromise of the keys of one certification center, other network members continue to work seamlessly with others, and blockchain technology may make it impossible to add a certificate to a center whose keys have been compromised, because all the events in the system are connected by cryptographic methods. In particular, such a system can be used on the Internet of Things. Each individual sensor must communicate properly with other components of the system as a whole. In order to enable the secure interaction of these components, they must exchange encrypted messages to verify their integrity and authenticity, the provisioning scheme of which is in the described scheme.","PeriodicalId":198390,"journal":{"name":"Cybersecurity: Education, Science, Technique","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127292216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
