Traceability Establishment and Visualization of Software Artefacts in Devops Practice: a Survey
(IJACSA) International Journal of Advanced Computer Science and Applications, Vol. 10, No. 7, 2019 Traceability Establishment and Visualization of Software Artefacts in DevOps Practice: A Survey D. A. Meedeniya1, I. D. Rubasinghe2, I. Perera3 Dept. of Computer Science and Engineering, University of Moratuwa, Sri Lanka Abstract—DevOps based software process has become the artefacts in the SDLC [2][3]. There are different forms of popular with the vision of an effective collaboration between the relationships between the homogeneous and heterogeneous development and operations teams that continuously integrates software artefacts. Some artefacts may be highly coupled, and the frequent changes. Traceability manages the artefact some may depend on other artefacts in different degrees, consistency during a software process. This paper explores the unidirectionally or bidirectionally. Thus, software artefacts trace-link creation and visualization between software artefacts, consistency management helps to fine-tune the software existing tool support, quality aspects and the applicability in a process. The incomplete, outdated software artefacts and their DevOps environment. As the novelty of this study, we identify the inconsistencies mislead both the development and maintenance challenges that limit the traceability considerations in DevOps process. Thus, artefact management is essential such that the and suggest research directions. Our methodology consists of changes are accurately propagated to the impacted artefacts concept identification, state-of-practice exploration and analytical review. Despite the existing related work, there is a without creating inconsistencies. Traceability is the potential to lack of tool support for the traceability management between relate artefacts considering their relationships [4][5]; thus, a heterogeneous artefacts in software development with DevOps solution for artefact management. -

System Calls Instrumentation for Intrusion Detection In
System Calls Instrumentation for Intrusion Detection in Embedded Mixed-Criticality Systems Marine Kadar SYSGO GmbH, Klein-Winternheim, Germany [email protected] Sergey Tverdyshev SYSGO GmbH, Klein-Winternheim, Germany [email protected] Gerhard Fohler Technische Universität Kaiserslautern, Germany [email protected] Abstract System call relative information such as occurrences, type, parameters, and return values are well established metrics to reveal intrusions in a system software. Many Host Intrusion Detection Systems (HIDS) from research and industry analyze these data for continuous system monitoring at runtime. Despite a significant false alarm rate, this type of defense offers high detection precision for both known and zero-day attacks. Recent research focuses on HIDS deployment for desktop computers. Yet, the integration of such run-time monitoring solution in mixed-criticality embedded systems has not been discussed. Because of the cohabitation of potentially vulnerable non-critical software with critical software, securing mixed-criticality systems is a non trivial but essential issue. Thus, we propose a methodology to evaluate the impact of deploying system call instrumentation in such context. We analyze the impact in a concrete use-case with PikeOS real-time hypervisor. 2012 ACM Subject Classification Security and privacy → Embedded systems security; Security and privacy → Intrusion detection systems Keywords and phrases Instrumentation, Mixed-criticality, Real-Time, System Calls, Host Intrusion Detection Systems Digital Object Identifier 10.4230/OASIcs.CERTS.2019.2 Funding This work has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No. 764785, FORA—Fog Computing for Robotics and Industrial Automation. -

Kernel (Linux): Windows Assimilation, Wake-On-LAN, AMD and Intel
Published on Tux Machines (http://www.tuxmachines.org) Home > content > Kernel (Linux): Windows Assimilation, Wake-on-LAN, AMD and Intel Kernel (Linux): Windows Assimilation, Wake-on-LAN, AMD and Intel By Rianne Schestowitz Created 26/11/2020 - 7:11am Submitted by Rianne Schestowitz on Thursday 26th of November 2020 07:11:12 AM Filed under Linux [1] Tuxera First to Bring Network Bandwidth-Saving SMB Compression Feature to Linux Environments[2] Tuxera First to Bring Network Bandwidth-Saving SMB Compression Feature to Linux Environments[3] Tuxera, a world-leader in quality-assured storage management and networking software, announced that the company's SMB server implementation, Fusion File Share by Tuxera, now offers transparent compression to platforms outside of Microsoft Windows. Compression is being rapidly and widely adopted in the storage industry as a feature in memory hardware, file system implementations, and also networking protocols such as Microsoft's server messaging block technology (SMB). The ability to compress files inline during transfer can significantly reduce bandwidth and transfer time. Microsoft released the transparent compression feature to their SMB protocol specification in early 2019. However, Tuxera is the first to implement SMB compression outside of Microsoft Windows, bringing this highly in-demand feature to Linux environments in enterprises around the world. Wake-on-LAN [4] With Wake-on-LAN (WoL) it can be slightly easier to manage machines in-house. You can fire up the workstation and start the day?s compile jobs (to catch up with overnight work by the KDE community, say) while drinking an espresso downstairs and doomscrolling. [...] If all the administrative bits are in place, then the simple way to wake up a machine is wake <hostname>. -
Bidirectional Tracing of Requirements in Embedded Software Development
Bidirectional Tracing of Requirements in Embedded Software Development Barbara Draxler _________________________________ Fachbereich Informatik Universität Salzburg Abstract Nowadays, the increased complexity of embedded systems applications re- quires a systematic process of software development for embedded systems. An important difficulty in applying classical software engineering processes in this respect is ensuring that specific requirements of safety and real-time properties, which are usually posed at the beginning of the development, are met in the final implementation. This difficulty stems from the fact that requirements engineering in general is not mature in the established soft- ware development models. Nevertheless, several manufacturers have recently started to employ available requirements engineering methods for embedded software. The aim of this report is to provide insight into manufacturer practices in this respect. The report provides an analysis of the current state-of-art of requirements engineering in embedded real-time systems with respect to re- quirements traceability. Actual examples of requirements traceability and requirements engineering are analyzed against current research in require- ments traceability and requirements engineering. This report outlines the principles and the problems of traceability. Fur- thermore, current research on new traceability methods is presented. The importance of requirements traceability in real-time systems is highlighted and related significant research issues in requirements engineering are out- lined. To gain an insight in how traceability can aid process improvement, the viewpoint of CMMI towards requirements engineering and traceability is described. A short introduction in popular tracing tools that support require- ments engineering and especially traceability is given. Examples of traceabil- ity in the development of real-time systems at the Austrian company AVL are presented. -
