Análisis de seguridad de una aplicación web móvil para sistemas android versión 9, utilizando OWASP MOBILE 2016.

La aplicación móvil siendo una aplicación hibrida que permite a los clientes consultar saldos, realizar compra de boletería para eventos, pagar servicios, etc. Se asume que esta aplicación guarda, manipula o contiene información sensible de cada cliente, por lo que es necesario garantizar la seguridad de esta información, ya que presentaría un riesgo legal y de reputación para la empresa. Es por ello, que se ha solicitado el permiso de realizar un análisis de seguridad de la aplicación móvil y así poder presentar un informe del estado actual en el que se encuentra, ya que en una revisión rápida con la herramienta Mobsf, Se evidenció que la aplicación no cuenta con todos los controles necesarios para que esta aplicación sea publicada en tiendas móviles (Play Store y AppGallery) Por tanto, este trabajo tiene como objetivo realizar un análisis de vulnerabilidades, con el fin de conocer el estado de seguridad actual de la aplicación. Para ello se utilizará como referente el proyecto Mobile top 10 de OWASP (Open Web Application Security Project) en la versión 2016, el cual identifica los riesgos de seguridad que pueden surgir de acuerdo a su nivel de criticidad y con esto dar prioridad a los riesgos más críticos. Para encontrar las vulnerabilidades o principales riesgos se realizarán 2 tipos de análisis, uno estático y otro dinámico de la aplicación, con el primero se podrá realizar una búsqueda profunda de su estructura, su código y seguridad enfocada en el top 10 de OSWAP Mobile, esto se hará con herramientas como Dex2jar, JD-Gui y APkTool, Frida, Burpsuite, etc., que permiten conocer el código fuente de la aplicación y su nivel de seguridad. Y para el análisis dinámico se utilizarán herramientas como Genymotion, Docker, ADB, Tamer, etc., que permiten emular la aplicación como si se tratara de un teléfono móvil real, pero en el que será posible analizar y capturar todas las acciones que se llevan a cabo dentro de la aplicación y así poder validar si presenta algún comportamiento anormal. Una vez realizadas las pruebas de seguridad se presentará un informe a la empresa, para que tengan el conocimiento de los riesgos y/o vulnerabilidades presentes que tiene la aplicación y a su vez se les presentaran una serie de recomendaciones necesarias para poder solucionarlas.The mobile application. It’s a hybrid application allow to the costumer check balance, buy tickets, pay home services. This application save information sensitive of each client, for this reason it’s necessary guarantee the security of this information, as it would generate legal risk and reputation for the company For this project, permission was requested to carry out a vulnerability test on the mobile application and thus be able to present a report of its current status, it was found that the application does not have all the necessary controls for them to be published in the store The goal for this work is carry out assessment security app mobile and to present the actual status. for this I will use to help me the project OWASP top 10 mobile, this project identifies the higher risk and give the options for priority for solves them To find the vulnerabilities or main risks, 2 types of analysis will be carried out, one static and the other dynamic of the application, with the first one can perform a deep search of its structure, code and security focused on the top 10 of OSWAP Mobile, this is It will do with tools such as Dex2jar, JD-Gui and APkTool, Frida, Burpsuite, etc., which allow to know the source code of the application and its security level. And for the dynamic analysis, tools such as Genymotion, Docker, ADB, Tamer, etc. will be used, which allow emulating the application as if it were a real mobile phone, but in which it will be possible to analyze and capture all the actions that are carried out. done within the application and thus be able to validate if it presents any abnormal behavior. Once the security tests have been carried out, a report will be presented to the company, so that they are aware of the risks and / or vulnerabilities present in the application and once a series of necessary recommendations are presented to be able to solve them

Towards Full Automated Drive in Urban Environments: A Demonstration in GoMentum Station, California

Each year, millions of motor vehicle traffic accidents all over the world cause a large number of fatalities, injuries and significant material loss. Automated Driving (AD) has potential to drastically reduce such accidents. In this work, we focus on the technical challenges that arise from AD in urban environments. We present the overall architecture of an AD system and describe in detail the perception and planning modules. The AD system, built on a modified Acura RLX, was demonstrated in a course in GoMentum Station in California. We demonstrated autonomous handling of 4 scenarios: traffic lights, cross-traffic at intersections, construction zones and pedestrians. The AD vehicle displayed safe behavior and performed consistently in repeated demonstrations with slight variations in conditions. Overall, we completed 44 runs, encompassing 110km of automated driving with only 3 cases where the driver intervened the control of the vehicle, mostly due to error in GPS positioning. Our demonstration showed that robust and consistent behavior in urban scenarios is possible, yet more investigation is necessary for full scale roll-out on public roads.Comment: Accepted to Intelligent Vehicles Conference (IV 2017

Uso de la cáscara de coco (Cocos nucifera) como medio filtrante en el tratamiento del agua del campo El Salto, Venezuela

Filtration is a purification stage that eliminates the suspended solids and remains of oils present in the water. This separation process has its main foundation through the use of a medium with suitable porosity and permeability characteristics with the purpose of implementing new alternatives during the treatment. Therefore, the use of coconut husk (Cocos nucifera) was evaluated as an alternative filter medium in the water treatment of El Salto Oilfield. For this purpose a characterization of the original process water conditions was performed, as well as the pulverization of the coconut shell, followed by the consequent selection of particles of 1 mm, 2 mm and 3 mm implemented to measure the effectiveness of the filtration process. Once the research was developed, it was observed that the application of a particle size of 2 mm generated a decrease in the concentration of suspended solids from 170 mg/L to 53 mg/L, representing an efficiency of 68,82 %. On the other hand, the decrease in the concentration of oils in water showed an efficiency of 98,55 %, concluding that the pulverized organic material in a particle size of 2 mm is a viable alternative that would represent a reduction in treatment costs.La filtración es una etapa de purificación que elimina los sólidos suspendidos y los restos de aceites presentes en el agua.

Expectancy versus experience–Comparing Portion-Size-Effect during pre-meal planning and actual intake

Research on eating behaviour has confirmed that portion size can substantially influence intake, a phenomenon known as the Portion-Size-Effect (PSE). Despite extensive research interest, there is limited understanding about the PSE on intended consumption (often measured by Expected Intake). It also remains unclear whether the presentation of food cues (e.g., Word Descriptors; Food Images) can modulate PSE during pre-meal planning. The current study addressed these questions by comparing PSE on intended versus actual consumption, with 62 participants based on a within-subject design. Participants firstly rated Expected Intake for a pasta dish of three sizes (400, 600, and 800 g), with each size presented in three different formats of food cues. The participants' actual pasta intake with the three portion sizes was tested in three ad libitum sessions over 7 weeks. The results suggested that Expected Intake increases as portion size becomes larger, following a nearly linear relationship. In comparison, the Actual Intake had a smaller increment after the presented portion size exceeded the ‘appropriate’ range. Relating to these results, the pre-meal PSE was found to be comparable to the actual PSE with moderate portion sizes (i.e., 600 g-400 g), but significantly stronger than the actual effect with large portion sizes. Overall, our data support the hypothesis that portion size can have a stronger influence on meal planning than actual food intake, and show that the format of food cues has considerable influence on Expected Intake. Studies of pre-meal planning should carefully consider the role of portion sizes and food cues on Expected Intake

La productividad total de los factores en las manufacturas de la región centro de México: 1993-2018

In Mexico there is a very heterogeneous panorama on productivity, which is reflected in one of the fundamental sectors of the economy, the manufacturing industry. Since, world-class companies coexist with a cluster of companies whose economies of scale present low productivity due to technological backwardness, which translates into a low growth rate of companies. This paper aims to identify the productive dynamics of the sources of growth in the central region in the manufacturing industry. The methodology used is based on a couple of instruments: The Solow Residual with an empirical model based on a Cobb-Douglas type function to determine the evolution of total factor productivity (TFP). Additionally, the sunrise/sunset diagrams are used to establish the contributions of each entity to the region's TFP. The results confirm growth of 0.12 in the TFP for the region throughout the period, the deconcentration of manufacturing activities in both the central region and Mexico City; so, it is concluded they ceased to be the largest nucleus industry of the country, which has implied a lower dynamism of the TFP at the national level and a decrease in the contribution of manufactures to the economic development of the country. Likewise, the performance presented by the entities of the central region registers inefficient levels; Mexico City being the great "loser," as it has decreased in TFP, and with this, has reduced its contribution and importance in Mexican manufacturing drastically.   Keywords: total factor productivity, central region, Mexico, manufacturing, sunrise/sunset diagrams.En México existe un panorama muy heterogéneo sobre la productividad, mismo que se ve reflejado en uno de los sectores fundamentales de la economía, la industria manufacturera. Ya que, conviven empresas de clase mundial con un cúmulo de empresas cuyas economías de escala presentan una baja productividad debido al rezago tecnológico, lo que se traduce en una baja tasa de crecimiento de las empresas. El objetivo del presente trabajo es identificar la dinámica productiva de las fuentes del crecimiento de la región centro en la industria manufacturera. La metodología empleada es a partir de un par de instrumentos: El Residuo de Solow con un modelo empírico a partir de una función tipo Cobb-Douglas para determinar la evolución de la productividad total (PTF) de los factores. Adicionalmente, se emplean los diagramas sunrise/sunset para establecer las contribuciones de cada entidad a la PTF de la región. Los resultados confirman, con un crecimiento de 0.12 en la PTF para la región en todo el periodo, la desconcentración de las actividades manufactureras en la que tanto la región centro como la Ciudad de México por lo que se concluye que dejaron de ser el mayor núcleo industrial del país lo cual ha implicado un menor dinamismo de la PTF a nivel nacional y con ello una disminución en la contribución de las manufacturas al desarrollo económico del país. Asimismo, el rendimiento presentado por las entidades de la región centro registra niveles ineficientes siendo la gran “perdedora” la Ciudad de México al tener decrecimientos en la PTF y con ello ha disminuido drásticamente su contribución e importancia en las manufacturas mexicanas.   Palabras clave: Productividad total de los factores, región centro, México, manufacturas, diagramas sunrise/sunset
