Objetive: An approach to a cooperative positioning algorithm is described in this paper, where a set of devices exchange GPS satellite observables and distance estimations with nearby devices in order to increase their positioning accuracy. Methodology: Different scenarios are established where GPS receivers exchange satellite information, using different ionospheric correction models, with the purpose of evaluating which conditions potentially improve the position accuracy. Conclusions: The results show our approach yields increased accuracy when all receivers use the same ionospheric correction model. Moreover, it was observed that the noise levels and uncertainty usually due to factors related to distance from remote devices to the main receiver did not influence positioning improvement when the separation between receiver pairs was large. Originality: The proposed algorithm allows for exploitation of the nature of the problem without increasing complexity at the hardware and software level, and to offer a low-cost cooperative positioning solution alternative. Restrictions: The results presented in the document are based on the execution of the cooperative algorithm using Rinex files of gnss reference stations. So, for scenarios in which the separation distances between reference stations are very high, the error levels in cooperative positioning can be very large.</p> William Javier Trigos Guevara, Gabriel Pedraza Ferreira, Raúl Ramos Pollan Copyright (c) https://revistas.ucc.edu.co/index.php/in/article/view/2744 Mon, 27 May 2019 00:00:00 -0400 Using Reverse Engineering to Handle Malware https://revistas.ucc.edu.co/index.php/in/article/view/2745 <p>This paper is a product of the research Project “Cyber Security Architecture for Incident Management” developed in the Colombian School of Engineering Julio Garavito in the year 2018. Introduction: Reverse engineering involves deconstructing and extracting knowledge about objects. The use of reverse engineering in malware analysis is extremely useful in understanding the functionalities and purposes of a suspicious sample. Methods: This paper makes use of Radare which is one of the most popular open source tools for reverse engineering, with the aim of dealing with malware. Results: A use case related to hacking of anti-sandbox malware is presented, in such a way that it is possible to analyze the behavior of the sample using a sandbox. Additionally, another use case is presented, where an in-depth analysis of a malicious Android application aimed to the audience of a popular event (FIFA World Cup 2018) is developed, making it possible to demonstrate the relevance of reverse engineering techniques in end-user protection strategies. Conclusions: This paper shows how the results of a reverse engineering process can be integrated with Yara rules, allowing for the detection of malware on the fly, and it also shows an alternative to automatically generating Yara rules through the yarGen generator. Originality: Use of Open Source reversing solutions by Colombian Law Enforcement Agencies has not been discussed previously, making this paper a notable element toward the modernization of the Army. Limitation: Different approaches and perspectives about the limitations in the use of reverse engineering by Law Enforcement Agencies are also shared.</p> Carlos Andrés Sánchez Venegas, Camilo Aguado Bedoya, Daniel Orlando Díaz López, Juan Carlos Camilo García Ruíz Copyright (c) https://revistas.ucc.edu.co/index.php/in/article/view/2745 Mon, 27 May 2019 00:00:00 -0400 Design and Implementation of A Visible Light-Based Communications System https://revistas.ucc.edu.co/index.php/in/article/view/2746 <p>Introduction: The publication is the product of the research “Prototipo de un sistema de telecomunicaciones basado en luz visible”, carried out at Universidad del Valle in 2018. Objective: The objective of this work was to build a functional prototype of a telecommunications system based on visible light through which the study of the most relevant characteristics, elements and behaviors in relation to this technology could be made. Methodology: To study the behavior of the developed prototype, different tests were performed varying some of the variables present in this type of telecommunications system. In addition, the developed prototype was tested in simplex and halfduplex modes. Conclusions: The results obtained when developing this work demonstrated the main characteristics of the prototype, its limitations, as well as the elements and variables that govern the most important aspects of its design. Originality: The presented design proposes the development of a low cost prototype, capable of obtaining the data to be sent through the connection to other devices through different communication peripherals or using the ADC present in the processing device used. Restrictions: Due to the reception elements used in the prototype there is a significant limitation on the maximum achievable transmission rate. In addition, it is important to mention that the conditions in which the prototype is deployed can affect its behavior, for example, elements that impede the line of sight between the telecommunications modules can stop the transmission.</p> Sebastian Caballero Barragan, Fabio G.

A piece of software with multiplatform capability, GUI, CLI and programming library was developed. The software allows for the intuitive construction of network frames, speeding up construction times, thus facilitating practical learning of the concept of encapsulation networking.</p> <p><strong>Objective:</strong> The research aims to build a multiplatform computing solution, with a GUI, CLI and programming library, in order to build network frames intuitively.</p> <p><strong>Methodology:</strong> The scope of the project is descriptive, since the development includes the analysis and implementation of the software and its components; as well as functional tests.</p> <p><strong>Results:</strong> The software was built according to the phases proposed in the methodology. A high percentage of students obtained average scores in the evaluation carried out on frames, packages and segments.</p> <p><strong>Conclusion:</strong> The results demonstrate the need to apply a new teaching methodology based on the elaboration of frames, to improve the learning process in computer networks.</p> <p><strong>Originality:</strong> A software solution that complements existing limitations in portability, versatility and ease of use is proposed. This solution is applicable both in the workplace and in the educational field.</p> <p><strong>Limitations:</strong> The processes of sending and capturing frames are separated in the software, meaning that TCP communication cannot be maintained. It is necessary to build a GUI application to capture network frames and not depend on a tool like Wireshark for visualizing the frames.</p> Marta López Muñoz, José Luis Alejandro Carrillo Valderrama Copyright (c) https://revistas.ucc.edu.co/index.php/in/article/view/2747 Mon, 27 May 2019 00:00:00 -0400 A hybrid methodology based on engineering tools for process standardization in accounting https://revistas.ucc.edu.co/index.php/in/article/view/2748 <p><em>Introduction: </em>This article is the final product for the investigation developed on the case study entitled “Standardization of the accounting process for the “Liga Colombiana Contra el Cáncer”.
