Organizations in this digital era use automated Information Technology Systems to process their information in order to support their missions. Web Applications (WA) offer services for business processes that imply handling organization valuable information. Their requirements have become more complex so as to guarantee Information Security.Security Risk Assessment (SRA) plays a critical role in protecting an organization's information assets. The main query has to do with which is the best form to determine what needs to be protected. This research will be referencing Simon's Pattern, specifically the intelligence phase, which is used to: a) examine and monitor SRA reality in WA, and b) identify and define essential problems in vulnerabilities determination and their consequences. This study establishes the bases for constructing an authentic problem pattern and how it can be attacked.
Simulating devices while developing software for embedded systems is advantageous if physical elements such as sensors are not available. In this work, we present the design and implementation of an extension named Custom Simulation of Virtual Devices (CSVD) for the Eclipse-based platform that has full support for the AADL meta-model, OSATE 2. The CSVD extension uses a Model-driven engineering approach to simulate virtual devices, which allows capturing an AADL model of a system that represents the connection between a local network of devices and a gateway through a serial bus, simulating its behavior at a data transmission level by being executed inside the QEMU emulator. Also, we present an example of our approach, based in a system modeled in AADL and its simulation using the CSVD extension.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
