A Sensitive File Abnormal Access Detection Method Based on Application Classification

As the access control mode of notepad files cannot meet the requirements of risk control for sensitive file hierarchical access, this paper proposes an application classification-based detection method for abnormal access to sensitive files. The application classification and file classification, access control policy mapping, and basic and preset policy detection are designed. Combining the operating system’s identification control of different applications at runtime, we monitor the abnormal access of sensitive files by hierarchical applications. The cross-access experiment of different levels of application to different sensitive files verified the effectiveness and security of hierarchical access control strategy and sensitive file abnormal access detection and reduced the risk of disclosure of sensitive files.

Multimodality Data Analysis in Information Security ETCC: Encrypted Two-Label Classification Using CNN

Due to the increasing variety of encryption protocols and services in the network, the characteristics of the application are very different under different protocols. However, there are very few existing studies on encrypted application classification considering the type of encryption protocols. In order to achieve the refined classification of encrypted applications, this paper proposes an Encrypted Two-Label Classification using CNN (ETCC) method, which can identify both the protocols and the applications. ETCC is a two-stage two-label classification method. The first stage classifies the protocol used for encrypted traffic. The second stage uses the corresponding classifier to classify applications according to the protocol used by the traffic. Experimental results show that the ETCC achieves 97.65% accuracy on a public dataset (CICDarknet2020).

Civil contracts in the area of air transportation: concept, characteristics, classification

The subject of this research is the concept, characteristics and interrelation of contracts in the area of air transportation. The article is dedication to understanding of legal nature and key elements of air contracts, specificity of their theoretical and practical application, classification; as well as aimed at creation of integral concept of regulatory system. Such understanding is acquired from a broad context of civil law literature and case law. Reference to the provisions of civil law doctrine allowed presenting an original view upon the subject matter, and propose recommendations on the improvement of aviation legislation. The main conclusion consists in the fact that civil law regulation of contracts in the area of air transportation is characterized by the existence of special contracts with peculiar features, which define the content of aviation legislation. With regards to each contractual construct, there emerge various question not only from the perspective of legal regulation and law enforcement (overbooking in the contract of air transportation of passengers), but also scientific approaches toward determination of the concept and nature of a particular contract (qualification of the shipping agreement as a bilateral or multilateral, legal nature of the shipping agreement for air cargo). The absence of universal understanding and interpretation of concept, contradiction of legislation, existence of legal gaps do not contribute to uniformity of aviation legislation, making it complicated for studying and application. The author also reviewed draft laws on regulation of air transportation and separate clauses thereof. Presented analysis reflects only few problematic aspects in the area of air transportation. The acquired results can be used in theoretical legal research, as well as legislative and practical activities.
