FRANCO, David A; PEREA, Jorge L  e  PUELLO, Plinio. Methodology for Detecting Vulnerabilities in Data Networks. Inf. tecnol. [online]. 2012, vol.23, n.3, pp.113-120. ISSN 0718-0764.

The main objective of this study was to design a methodology for the detection of vulnerabilities in data networks. This involved the development of different phases, called recognition, port scanning and service enumeration, and vulnerability scanning, each of which is supported by software tools. The results of each phase supplied the necessary data for implementing the following stages. To validate the usefulness of the proposed methodology this was implemented in the data network of the University of Cartagena in Colombia, finding different types of vulnerabilities. Finally, based on the results, it was found that the proposed methodology is useful for detecting vulnerabilities in data networks, demonstrating their importance to the area of computer security.

Palavras-chave : vulnerability detection; service enumeration; port scanning; information security.
