Evaluación de Tecnologías UTM (Unified Threatment Management) y NGFW (Next Generation Firewall) para detección de vulnerabilidades en la red.

Abstract

Attack techniques through network vulnerabilities have maintained a costly evolution, so it is necessary to identify and protect intrusions to avoid a possible risk of information and the fall of services that have an impact on hospitalization, emergency, and hospitalization. External consultation technologies have been developed for better network security such as UTM (Unified Treatment Management) and NGFW (Next-Generation Firewall) servers, which offer a set of tools for the protection of a network. In the investigation, it is proposed to determine the best option for the detection and protection of vulnerabilities between these two technologies. The scenarios are implemented in the network, and tests are carried out to measure the proposed indicators. Values are determined for productivity, utilization, availability, response time, accuracy. Samples are taken at the same times the day of each scenario, statistical tests are established according to the investigation, and the data number. The student t distribution with Shapiro-Wilk is applied for hypothesis testing, a Likert Diagram is proposed to evaluate the variables qualitatively, and the indicators are obtained: Network Server Productivity 0% VS NGFW 77% VS UTM 65%, Use Network Server 56% VS NGFW 69% VS UTM 58%, Response Time Network Server -141% VS NGFW 90% VS UTM 70%; In the Availability and Accuracy indicators the two technologies maintain an outstanding value, over an inferior range of the Ambato Hospital Server. This allows us to determine the improvement in the availability of the network using the application of the proposed technologies. It is also determined that of the techniques applied, the Next Generation Firewall offers better performance, so a guide is established for its implementation in similar scenarios.
