Mantenimiento de la aplicación web de información productiva agropecuaria CONAGOPARE Chimborazo

Abstract

The objective of this Curriculum Integration Work was to carry out the software maintenance process in the agricultural productive information system CONAGOPARE Chimborazo. We utilized the Mantema methodology for the execution of the project because it is focused on software maintenance, allowing to have an organized documentation since it follows a process of activities and tasks. We determined the type of maintenance to be performed through an analysis, it was a perfective maintenance in this project because we increased the functionalities that were obtained through an interview with the client in charge of the application, thus 25 functionalities were developed, going from 32 before maintenance to 57 after maintenance. It was also corrective because we made changes in user interfaces and bugs; in addition, we applied good security practices in the system. The evaluation of the project was carried out by means of functionality and security indicators, so we obtained initial results through pen testing before performing software maintenance in order to have comparison data. We carried out the functionality measurement process using the sub-indicators obtained from ISO 25010 standard, which are completeness, accuracy, and functional relevance. On the other hand, for the security measurement we utilized the sub-indicators of confidentiality, integrity, availability (CIA), obtained from ISO 27001 standard. We conclude that the results for functionality were favorable due to a 22% decrease in functional errors for completeness and functional relevance. The security results after applying 7 types of penetration attacks to the 51 functionalities developed after maintenance were favorable, obtaining a vulnerability minimization of 47.50%. The use of the good security practices manual is recommended.
