Item Aplicación del modelo matemático similitud de coseno para identificar gustos de usuario en una red social(Universidad Santiago de Cali, 2021) Osorio Vélez, Carlos Augusto; Sánchez Quiroga, Christian; Dussan Clavijo, Ciro AntonioThe present research establishes as a general objective the application of the mathematical model similarity of cosine to identify user tastes in a social network, incorporating an algorithm that provides precision, data cohesion and performance. The methodology used is applied-quantitative, focused on the needs and practical searches for the execution of operational processes and systems, with the Scrum model the framework was developed that planned the Sprints with weekly phases during the months of November and April, performing the proper model inspections. The results highlight that the software architecture for the application of the cosine similarity algorithm in the social network, constituted in the programming language, framework, database through Python, Flask and MySQL, has proposed a structure of technological functionality with a series of components towards a specific end, since the development of the application promotes a useful product, when executing the algorithm an exact count of the data from 100% to 25% was achieved, taking into account the affinity of the preferences established by the client in the search, the integration of the cosine algorithm to the web system with the social network model, allowed to recommend sites of interest taking into account the information provided, using a type applied to current trends such as social networks and algorithms based on recommendation systems that in the present case I use content-based filtering recognizing characteristics and attributes Search items to suggest products or services that the customer may be interested inItem Beneficios de las redes definidas por software y el protocolo openflow(Universidad Santiago de Cali, 2020) Bermúdez Escobar, Cristian David; Rodríguez Taborda, Jesús Alexander; Dussan Clavijo, Ciro AntonioWith the emergence of software-defined networks Defined Networking (SDN), and the use of the Openflow protocol in SDNs, new intelligent network architectures have evolved, bringing with them various advantages when applied together. On the other hand, the technological advances of the last decades, the development of new devices, higher transmission speeds, connectivity requirements, the development of new IoT applications and online services, make traditional network architectures that were thought to endure unsustainable over time and imposed as standards, today they are little used, such is the case of X.25, ATM, among others. therefore, a design evolution of these network architectures is demanden. At this point, the software defined network (SDN) together with the Openflow protocol appear as an evolution of a viable alternative network architecture that allows programming the network and opening the possibility of creating new services and more efficient applications to meet the requirements. Real in a centralized and programmable way. Finally, this work starts from a general context explaining the basic concepts related to software-defined networks, the types of controllers, layers and interfaces it handles. Subsequently, the advantages of SDNs over networks, virtualization will be determined and the use of the Openflow protocol in Programmable Networks will be identified. The article is made based con descriptive studies, information was obtained from various sources, such as articles from databases, web magazines, corporate pages and books.Item Conceptos y Referencias en Teoría de la Información y las Telecomunicaciones: Aspectos Analógicos(Editorial Universidad Santiago de Cali, 2025-04-25) Vélez Varela, Fernando; Dussan Clavijo, Ciro Antonio; Santafé Ramón, Yesid Eugenio;Item Descripción del funcionamiento de ataque del Malware ransomware (WannaCry) en sus procesos de infección, encriptación y propagación en el sistema operativo Windows(Universidad Santiago de Cali, 2019) Rodríguez Vallecilla, Anderson; Mina Loango, Jorge Enrique; Dussan Clavijo, Ciro AntonioThe present monograph consists of the operation of an attack, one of the malware programs (malware / virus) with more impact worldwide, due to computer attacks in 2017 to several companies using the windows operating system. The ransomware WannaCry this malicious program that incorporates code to perform the exploitation of vulnerabilities of windows operating systems, which the objective of an attack is to encrypt sensitive information asking for rescue for it. Given this, this monographic research is exposed by means of sessions which is composed of three, the which speaks of the infection where part of the code is shown, encryption and propagation of this malicious program exposing its attack scenario, in order to show a global view on the structure both the danger of the source code of the virus and the vision of users or victims.Item Una mirada a las profundidades de la Deep Web usando FreeNet(Universidad Santiago de Cali, 2019) Valencia Martínez, Ana Isabel; Hoyos Pérez, Andrés José; Dussan Clavijo, Ciro AntonioThis document takes a look at the Deep Web and how to access it via Freenet, an alternative to the more popular Deep Web browser, TOR. For the completion of this document, we made use of personal experience using Freenet, as well as of the available literature about the Deep Web, the World Wide Web, and Freenet itself. As a result, we present a general view of the Deep Web, the organization of the great web (the internet), the content found in the Deep Web, the functioning of internet browsers, the safety measures to observe when browsing the Deep Web, and the ways in which Freenet guarantees the safety of its users when entering the Deep Web
