Models and scenarios of implementation of threats for internet resources

Abstract

To facilitate the detection of various vulnerabilities, there are many different tools (scanners) that can help analyze the security of web applications and facilitate the development of their protection. But these tools for the most part can only identify problems, and they are not capable of fixing them. Therefore, the knowledge of the security developer is a key factor in building a secure Web resource. To resolve application security problems, developers must know all the ways and vectors of various attacks in order to be able to develop various protection mechanisms. This review discusses two of the most dangerous vulnerabilities in the field of Web technologies: SQL injections and XSS attacks (cross-site scripting – XSS), as well as specific cases and examples of their application, as well as various approaches to identifying vulnerabilities in applications and threat prevention. Cross-site scripting as well as SQL-injection attacks are related to validating input data. The mechanisms of these attacks are very similar, but in the XSS attacks the user is the victim, and in the SQL injection attacks, the database server of the Web application. In XSS attacks, malicious content is delivered to users by means of a client-side programming language such as JavaScript, while using SQL injection, the SQL database query language is used. At the same time, XSS attacks, unlike SQL injections, harm only the client side leaving the application server operational. Developers should develop security for both server components and the client part of the web application.

Homotopism of Homological Complexes over Nonassociative Algebras with Metagroup Relations

“…, where p = {g 1 , ..., g n−m+1 } q(n−m+1) . Therefore, from (20)-( 24) and ( 26)- (30) it follows, that Y is a smashly G m -graded B-bimodule. This construction supplies X with the smashly G m -graded B-bimodule structure.…”

“…The obtained results will be useful for further studies of cohomology theory of nonassociative algebras and noncommutative manifolds with metagroup relations, structure of nonassociative algebras, operator theory, spectral theory over Cayley-Dickson algebras, PDEs, noncommutative analysis, solutions of PDEs with boundary conditions, noncommutative geometry, mathematical physics, and their applications in the sciences. Then there are possible applications in mathematical coding theory, informatics, security of internet resources [29][30][31], because coding frequently uses algebras. This is caused by the fact that conditions imposed on metagroups are weaker than for groups.…”

“…Notice that if both vectors q(n) and s(n) in g 1 , ..., g n−m+1 terms correspond to q(n − m + 1) order of multiplication, that is (30)…”
