Deep Semisupervised Learning-Based Network Anomaly Detection in Heterogeneous Information Systems

The extensive proliferation of modern information services and ubiquitous digitization of society have raised cybersecurity challenges to new levels.With the massive number of connected devices,opportunities for potential network attacks are nearly unlimited.An additional problem is that many low-cost devices are not equippedwith effective security protection so that they are easily hacked and applied within a network of bots(botnet)to perform distributed denial of service(DDoS)attacks.In this paper,we propose a novel intrusion detection system(IDS)based on deep learning that aims to identify suspicious behavior in modern heterogeneous information systems.The proposed approach is based on a deep recurrent autoencoder that learns time series of normal network behavior and detects notable network anomalies.An additional feature of the proposed IDS is that it is trained with an optimized dataset,where the number of features is reduced by 94%without classification accuracy loss.Thus,the proposed IDS remains stable in response to slight system perturbations,which do not represent network anomalies.The proposed approach is evaluated under different simulation scenarios and provides a 99%detection accuracy over known datasets while reducing the training time by an order of magnitude.

Cosmetology Services in Ukraine:Problems of Legal Regulation

The demand for cosmetology services has been recently growing in Ukraine,but there is no proper legal regulation for their provision.The aim of the article is to analyze the current status and specific features of legal regulation for the provision of cosmetology services in Ukraine,as well as to suggest the improvements to Ukrainian legislation in this area.The main objective is to distinguish the problems and to develop suggestions to improve regulatory legal acts regulating the provision of cosmetic services in Ukraine.Materials to identify the specific features of the current state of legal regulation in regard to the provision of cosmetology services in Ukraine were the legislation and case law of Ukraine,the works of Ukrainian scholars,analytical materials and Internet resources.The methodological basis of the research is general and special methods of scientific cognition,the use of which is due to specific features of the legal regulation of the market of cosmetology services.It has been stated that there is currently no normatively established procedure and specific features for the implementation of activities for the provision of cosmetology services in Ukrainian laws;there are also no standards for their provision,treatment of complications and training of qualified personnel.The author has formulated proposals to improve the legislation regulating the provision of cosmetology services and cosmetic care to the Ukrainian population.The Ministry of Health of Ukraine was offered to develop and approve a regulatory legal act governing the procedure for the provision of cosmetology services and the list of services that can be provided exclusively by health professionals.
