XML Schema-based Minification for Communication of Security Information and Event Management (SIEM) Systems in Cloud Environments

XML-based communication governs most of today's systems communication, due to its capability of representing complex structural and hierarchical data. However, XML document structure is considered a huge and bulky data that can be reduced to minimize bandwidth usage, transmission time, and maximize performance. This contributes to a more efficient and utilized resource usage. In cloud environments, this affects the amount of money the consumer pays. Several techniques are used to achieve this goal. This paper discusses these techniques and proposes a new XML Schema-based Minification technique. The proposed technique works on XML Structure reduction using minification. The proposed technique provides a separation between the meaningful names and the underlying minified names, which enhances software/code readability. This technique is applied to Intrusion Detection Message Exchange Format (IDMEF) messages, as part of Security Information and Event Management (SIEM) system communication hosted on Microsoft Azure Cloud. Test results show message size reduction ranging from 8.15% to 50.34% in the raw message, without using time-consuming compression techniques. Adding GZip compression to the proposed technique produces 66.1% shorter message size compared to original XML messages.Comment: XML, JSON, Minification, XML Schema, Cloud, Log, Communication, Compression, XMill, GZip, Code Generation, Code Readability, 9 pages, 12 figures, 5 tables, Journal Articl

Authentication in Welded Clad Plate with Similar Material and Thickness

This paper continues the research previously done by authors on numerical modelling of the dissimilar welded joints with varying clad thicknesses using a commercial finite element software. The current study simulates the welding conditions of a similar clad plate with a thin thickness. The computer simulated outcome then verified with the measured data of from other researchers. A close match between the numerical models and the experimental data was found.Peer reviewedFinal Published versio

The Group of Homotopy Self-equivalences Inducing the Identity on the Homotopy Groups of an F0F_{0}-Space is Finite

Let $X$ be an $F_{0}$-space and let $\mathcal{E}_{\#}(X)$ the subgroup of homotopy classes of homotopy self-equivalences of $X$ inducing the identity on $\pi_*(X)$. The aim of this paper is to prove that $\mathcal{E}_{\#}(X)$ is finite
