Item A través de escenarios oscuros: Impacto del uso de inteligencia artificial generativa en el campo de la seguridad de la información en un país de América latina(Universidad Santiago de Cali, 2023) Castro, Mathews Jovel; Marcus Martínez, Alejandro (Director)Artificial intelligence, and in particular generative artificial intelligence, has enabled the use of generative algorithms that allow cybercriminals to automate and customize their attacks, adapting them to the specific vulnerabilities of their targets. This is particularly damaging to the financial, government, and critical infrastructure sectors. On the other hand, the creation of fake content, deepfake, has proliferated thanks to the poor performance of such algorithms, leading to disinformation and manipulation campaigns that affect the political and social stability of a region. This article explains the negative impact of the use of generative artificial intelligence in the field of information security in Colombia. To do this, research was conducted on the threats of the use of generative artificial intelligence in information security. Once the research was conducted, a comparison was made between the threats and impacts of the use of generative artificial intelligence in information security in the international context versus Colombia. Finally, the results obtained from the research on the risks were documented, as well as the comparison of the threats and impacts of the use of generative artificial intelligence in the field of information security in the international context versus Colombia.Item Adaptación e integración de los flujos de información de los procesos de fabricación con los diferentes ámbitos de la organización a través del modelado de sistemas complejos(Universidad Santiago de Cali, 2021) Tarapues Cuastumal, Alex Roberto; Fernandez Cabrera, Angel Sebastian; Girón Cruz, Jorge Andrés (Director)This work is carried out based on one of the needs that companies present today, which arises due to the evolution of a deman ding and very competitive market where is crucial for organizations to modify their structure and design properly their processes.
