Ítem Ciberdefensa Abierta: El Ciclo de la Inteligencia de Amenazas con Software LibreLozano Arana, Eduard David; Ferro Escobar, RobertoThis article establishes the fundamental guidelines for adopting projects developed within free and open‑source software communities in corporate environments, with an emphasis on their application in cybersecurity systems. Its aim is to highlight the potential of these solutions to build secure, legitimate, and scalable ecosystems capable of integrating multiple layers of protection and threat intelligence. It examines the strategic impact of free software on modern cyber defense, addressing the technical and legal implications associated with the various available licenses. The article also clarifies the differences between free software and proprietary software, emphasizing that access to source code does not necessarily imply zero cost or the absence of restrictions. Additionally, it categorizes the main types of projects found in open‑source communities, assessing their ability to integrate with enterprise security standards and regulatory frameworks. This approach seeks to encourage the informed adoption of open solutions, promoting sustainable and auditable practices in digital risk management.Ítem RIS para Mejorar la Conectividad Inalámbrica en BogotáMoreno Reinel, Jahir Leonardo; Ferro Escobar, RobertoElectromagnetic waves used in mobile services and next-generation networks face significant propagation constraints in urban environments due to high attenuation and limited building penetration. In cities, these limitations are compounded by sparse, antenna density, spectrum congestion, and geographic factors, leading to areas of poor connectivity and deepening the digital divide. This study examines connectivity quality in Bogotá by analyzing data sources such as user-reported reception and proposes the use of Reconfigurable Intelligent Surfaces (RIS) to create intelligent radio environments, drawing on the predominant literature on this technology. RIS are programmable metasurfaces capable of manipulating electromagnetic waves to increase information capacity and optimize the wireless channel. We outline potential deployment scenarios and the challenges relative to traditional designs currently implemented in the capital.Ítem Diseño de un Sistema C-UAS para la neutralización de UAS No identificados. Caso de estudio Aeropuerto El Dorado, Bogotá, ColombiaPeña Herrera, Thomas Felipe; Ferro Escobar, RobertoThe growing threat of Unmanned Aerial Systems (UAS), commonly known as drones, to airport security and operations is a significant challenge in Colombia. UAS flights near airports require the adoption of robust defense solutions to prevent collisions, disruption of air operations, and the risk of unauthorized surveillance. To address this problem, a Counter Unmanned Aircraft System (CUAS) was designed for El Dorado International Airport in Bogotá, focusing on neutralizing hostile drones through jamming. The HTZ Warfare software was used, employing high-precision inputs such as digital terrain models (DTMs), building footprints (BGLs), clutter layers, and ITU-R P.452-18 propagation models. Through simulation of the coverage of 13 strategically placed jammers, an effective neutralization area was determined within the airport environment. The direction-finding (DF) detection system was described theoretically, although not implemented in the practical phase. Validation by a telecommunications expert highlighted a 98% reliability of the design, blocking 2.4 GHz control signals from 2 to 120 m in altitude throughout the airport area, subject to field conditions and operational feasibility. Furthermore, a survey revealed a favorable perception of the implementation of these systems in civil airports. It is concluded that the integration of high-precision simulation tools allows for the evaluation of viable and effective solutions for mitigating UAS threats in critical infrastructure.Ítem OAI-SDR: Framework Inteligente de Búsqueda y Descubrimiento para Repositorios OAI-PMH mediante Aprendizaje Automático y Análisis SemánticoLeón Sandoval, Jhon Helmit; Ferro Escobar, RobertoOAI-SDR is a clever hybrid search tool crafted for OAI-PMH repositories, blending the straightforward BM25 method—which quickly spots keywords—with smarter embedding techniques that really get the meaning behind what you’re looking for. It kicks off by gathering and tidying up metadata, then enriches the content and turns it into handy vector formats. From there, it mixes the results using something called Reciprocal Rank Fusion, and if you want, you can add a learning-to-rank twist to polish the top picks even more. To see how well it works, they checked it with measures like nDCG@10, MAP@10, Recall@10, how often users click (CTR), and how fast they find something useful.Ítem Aproximación de un radio enlace PTP para misión crítica en Retail(Universidad Distrital Francisco José de Caldas) ROJAS SANCHEZ, DAVID EDUARDO; Ferro Escobar, RobertoDigital transformation has redefined connectivity expectations, demanding network architectures that are not only fast but exceptionally robust. This paradigm is a challenge for missioncritical applications, where the congested radio spectrum degrades service quality. The retail sector is a clear example,where operations (payment processing, inventory, promotions) are entirely dependent on stable connections. An interruption, however brief, translates into direct economic losses. This behavior is accentuated in Colombia, where according to the Financial Superintendence[1], for the first quarter of 2025, 66% of all monetary operations were carried out via the Internet and mobile applications. This paper addresses this challenge in a hostile environment: a convention center where high-density crowds saturate mobile networks. Internal survey data validates the problem: 85% of attendees report connection failures, and over 80% of digital transactions take more than 2 minutes, affecting point-of-sale operations. To ensure business continuity, the feasibility of a 2.3 km point-to-point (PTP) radio link is proposed and analyzed. Specifically, a high-availability network architecture is designed, consisting of: • A primary link in the 60 GHz band, immune to interference from the shared spectrum. • A backup link in the 5 GHz band to mitigate atmospheric effects. The solution is managed by Layer 3 failover with IP SLA for near-instantaneous recovery and unifies the networks of both points using a VXLAN overlay, ensuring deterministic connectivity isolated from the public network chaos.Ítem OAI-SDR: Framework Inteligente de Búsqueda y Descubrimiento para Repositorios OAI-PMH mediante Aprendizaje Automático y Análisis SemánticoLeón Sandoval, Jhon HelmitOAI-SDR is a clever hybrid search tool crafted for OAI-PMH repositories, blending the straightforward BM25 method—which quickly spots keywords—with smarter embedding techniques that really get the meaning behind what you’re looking for.

However, this centralization also introduces new security challenges, as the controller becomes a critical point of vulnerability. Among the most significant threats are Denial-of-Service (DoS/DDoS) attacks, which can exhaust control-plane resources through malicious traffic flows and degrade overall network performance. This article presents a review of vulnerabilities in SDN environments, the main detection techniques proposed in literature and the key current challenges. Based on this analysis, a two-layer hybrid detection architecture is proposed, combining lightweight detection techniques for early anomaly identification with on-demand ML/DL based classifiers for suspicious traffic, highlighting the need for specialized mechanisms that preserve controller performance while optimizing computational cost.Ítem Desarrollo de una aplicación web para realizar el registro y consulta de proveedoresGutiérrez Cuervo, Manuel Alejandro; Acosta Díaz, Jaime Leonardo; Vargas Tamayo, Luis Fernando; Vargas Tamayo, Luis Fernando [0000-0001-6041-3323]This document contains information about the application of some knowledge elected by the authors in the development of an application for registration and consultation of suppliers managed through a web application. In this article the reader will have opportunity to identify some methodological and technical components used in the implementation of good practices for developing software that ensures a minimum range of quality. The methodology of Rational Unified Process (Rational Unified Process in English, usually summarized as RUP) is used as part of software development project. Additionally, the Unified Modeling Language (UML LUM or by its acronym in English, Unified Modeling Language) is used by the authors for application documentation. Likewise, the Structured Query Language or SQL (for its acronym in English Structured Query Language) was chosen for the persistence component of the project. For the development and implementation of software was chosen C # (pronounced if sharp in English). Finally, Web Service platform is used, consumed on a mobile device to manage the software and database.Ítem Diseño de un sistema de control para la reutilización de aguas superficiales y subterráneas en terrenos agrícolas mediante tecnologías IOT.Saldaña Anzola, Johan David; LOPEZ SARMIENTO, DANILO ALFONSOThe efficient and sustainable use of water resources currently represents a critical challenge in rural and agricultural areas, especially in those that rely on both surface and groundwater sources. Poor management of these resources not only leads to excessive or insufficient water usage but can also result in severe issues such as the overexploitation of aquifers and the depletion of surface water bodies. Furthermore, excessive water accumulation in agricultural lands—whether due to rainfall or uncontrolled irrigation—can cause soil erosion and the loss of essential nutrients, ultimately affecting both agricultural zones and rural residential areas over the long term. Traditional irrigation techniques lack automated systems and effective control mechanisms, leading to significant water waste, particularly in regions where water availability is limited or seasonal. Existing solutions do not adequately incorporate the necessary technologies to remotely monitor and manage irrigation systems, resulting in soil saturation and increased erosion risks, which in turn displace key nutrients essential for soil health and proper crop development. This project aims to design and develop an automated irrigation control system for agricultural fields using IoT technologies to optimize the use of surface and groundwater resources. The system is designed to efficiently monitor and manage both the collection and utilization of these water resources. Surface water will be collected through drainage and harvesting systems such as French drains, capturing both rainwater and groundwater. The integration of the IoT system will enable the remote activation and deactivation of the motor pump for the irrigation system, as well as the control of tank filling, providing a sustainable solution for agriculture. This will improve water use efficiency and contribute to environmental preservation.Ítem Desarrollo de un sistema para cálculo de distancias en movilizaciones de torres de workover y perforación con data GPSArdila Ortiz, Camilo Andres; Cárdenas Castiblanco, José RobertoIn the Oil & Gas industry, there are drilling or workover rigs that perform drilling and well maintenance tasks for the production of oil and gas. The dynamics in this industry segment involve an operating company (such as Ecopetrol, Hocol, Parex, etc.) contracting a service provider company that owns RSUs, rigs, and/or drilling rigs to perform these tasks. These rigs are large mobile structures that are moved from one location to another, especially in rural areas and, in some cases, in difficult-to-access locations, to carry out these operations. The operating company establishes a contract in which it has a certain number of rigs available that can be moved according to its business plan in the blocks, clusters, or wells it controls. Based on the activities requested by the operating company, the rig owner executes and bills these activities. One specific case is mobilization, which is one of the most expensive processes. It is typically billed based on load, trajectory, and sometimes time as a measure of effort. While the load is easily known, as well as the distance, it is not always certain whether the planned route was actually taken and whether the kilometers billed were accurate, leading to potential financial losses for the rig owner. This project presents the development of a system that allows obtaining longitude and latitude coordinates for drilling and workover rigs using an IoT device that sends this data to the cloud for processing. This enables tracking the trajectory of a drilling or workover rig mounted on its base unit from one point to another, with the aim of providing accurate information to correctly calculate the mobilization operation cost and ensure proper billing to the operators by the service provider company. To address this problem, the proposed solution involves using a device that captures the coordinates while the rig is in motion. Once it arrives at a location and regains network connectivity, all stored data is sent for further processing. The data is then used to calculate the trajectory using the Haversine formula. The prototype outlines the need for a backup power system and the connection to GPS and Ethernet modules, among others, to obtain and transmit information such as longitude, latitude, time, altitude, date, and the number of satellites. This work focuses on developing the logic of the solution, including coding the microcontroller for capturing, storing, and transmitting information, as well as creating the IoT gateway service, implementing a broker, and establishing the basic business logic to determine the distance. Additionally, it outlines a potential physical implementation of the solution, taking the context into account. The project successfully captures and sends the data to the cloud for storage and calculates the distance traveled within a given time interval.Ítem Evaluación de solución Small Cell 5G NSA para interiores en un ISP colombianoVega Valencia, Brayan Andres; Gonzalez Riaño, Oscar Julian; Pedraza, Luis FernandoThis project focuses on the evaluation of a Small Cell 5G NSA (Non-Stand Alone) solution provided by a technology supplier in the context of the recent 5G spectrum allocation in Colombia. This development is crucial for Colombian ISPs seeking to commercially implement this new technology, utilizing the existing 4G LTE Core (EPC) infrastructure to facilitate the introduction of the advantages of mobile 5G through an NSA approach. The project's methodology is structured in four key stages: a comprehensive analysis of relevant literature, a detailed understanding of the low-level design provided by the technology supplier, the collection and analysis of data obtained from tests conducted up to June 2024, and a conclusive analysis of the data to validate the effectiveness of the proposed solution. The results obtained provide valuable insights into the performance of Small Cell 5G NSA solutions in indoor environments, significantly contributing to existing knowledge and laying the groundwork for future implementations by ISPs in Colombia and other emerging markets. In terms of coverage, the Walking Test showed significant improvements after the implementation of Small Cells, with the signal strength RSRP improving from -98.66 dBm on LTE to -78.02 dBm on 5G NSA, and the maximum throughput in the area with the least coverage increasing from 17.42 Mbps to 1121.55 Mbps, respectively. Regarding energy consumption, the Symbol Shutdown and Carrier Shutdown tests achieved savings of 10% and 13%, highlighting the solution's capability to optimize energy usage without compromising service quality. These conclusions demonstrate that the 5G NSA solution improves network capacity, efficiency, and energy consumption, contributing to a more sustainable operation. The project marks a significant advancement in strengthening telecommunications infrastructure in Colombia, evaluating one of the first steps towards transitioning to advanced mobile technologies at a crucial time for 5G network deployment.Ítem Diseño De Guias De Laboratorio De Ciberseguridad Para La Especialización En Teleinformática De La Universidad Francisco Jose De CaldasChaparro Vargas, Juan Jose; Cardenas Castiblanco, Jose RobertoThis document presents the work of the design of the first phase of the cybersecurity laboratory of the Specialization in Teleinformatics of the Universidad Distrital Francisco José de Caldas; In the first instance a presentation of the work is given where the problem is contextualized, which basically focuses on the lack of a practical component in the specialization in teleinformatics in the area of cybersecurity, which impacts the learning and exploration of the students of the specialization and even more taking into account that it is in the field of teleinformatics which infers in a broad relationship with the computational, cybernetic, technological and technological use, cybernetic, technological and telecommunications, taking into account the guidelines of the CySA and CISSP certifications where the Security Assessment and Testing domain was mainly covered, using open source Python tools and then laboratory guides were elaborated for its understanding and development, where each one includes a space of explanation of how it is done and what the practice is for.
