    Plataforma de seguridad perimetral para un ISP (proveedor de servicios de internet)

    Today computer security plays an important role in all sectors of society starting with government agencies, educational institutions, financial institutions, health centers and of course companies; the commitment and responsibility of each of them is to safeguard their data and information of people which leads to use platforms to efficiently manage the threats that try to breach the security of a network. This research project aims to implement a perimeter security platform for the company Simantec, due to the business line of the company and the flow of information it handles, a perimeter security system covers the needs and requirements demanded by this entity, being the highest priority the protection of all data considered the most important asset of the entity. The implementation of a proprietary UTM (Unified Threat Manager) at the boundary of the Internet and LAN will mitigate the threats to which the data is exposed, functions such as antivirus, anti-spyware, anti-spam, network firewall, intrusion prevention and detection, and content filtering will maximize the security of the information. In addition, the creation of VPN to access the internal network from anywhere and access the company's services will increase security. At the same time, another defense equipment will be configured, a software UTM with the same functions of the proprietary UTM. The objective is to compare the two threat managers, analyze the advantages and disadvantages of each one in order to choose the best option considering cost/benefit, features, performance, security and above all profitability. Finally, we propose the development of a plan of good security practices, with the aim that employees incorporate as a habit certain methods to prevent attacks carried out through malicious activities by third persons.

    Gestión y calidad de servicio para una red IPTV con tecnología GPON
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Maestría en Telecomunicaciones, 2021) Chico Analuisa, Luis Enrique; Pallo Noroña, Juan Pablo
    At present, fiber optic networks have become the main means for the distribution of multimedia content at a global level, they provide networks with a large bandwidth for the flow of traffic that passes through their infrastructure, GPON is one of the most widely used standards for the deployment of fiber optic networks, however disorderly growth and limited management policies have caused the services provided by these networks to degrade, where end users receive deficient services. The company FASTER_ISP has a GPON network to provide Internet access to its end customers, which has an ODN infrastructure and an internal plant with good characteristics, however, it does not have a management system and QoS service quality, causing various technical problems in its operation and functioning, where there are various problems for the distribution of multimedia services such as IPTV, Video calls, Online games, Streaming, etc. The objective of this scientific research is to provide a management system and quality of service for IPTV and restructure the GPON network of FASTER_ISP, in the first instance the operation of this type of network is analyzed, conceptualizing its main elements and characteristics, followed From this, the current state of the network is determined, where by means of field views and information gathering, its entire infrastructure is determined, the class of equipment that is being used, its mode of operation and end-user management. With the information obtained, a solution is analyzed and proposed that allows to improve the administration of the network with respect to the multimedia services that are delivered to the end users of FASTER_ISP, so that by means of an operation algorithm the GPON network of FASTER_ISP is managed with perimeter security and quality of service policies, as well as the use of an optical budget for the construction of the last mile network, and finally it is determined that for the distribution of IPTV, it is necessary to implement a local IPTV server, on a dedicated line for video that guarantees the quality of experience of the users in the reception of this service. For the implementation of the proposed system, it is first verified that the last mile facilities meet the optical budget requirements, followed by configurations in the Core and edge equipment, with efficient security and quality of service policies, once This ends, we proceed to the installation of the local IPTV XTREAM server, the same one that allows the distribution of video content, over the local network, optimizing resources and guaranteeing the quality of the QoE experience. Finally, the corresponding tests are carried out, determining that the implemented system meets all the objectives proposed in the investigation.
