With looming threats from hackers, identity and corporate data thieves, it is impossible to avoid doing penetration testing at the corporate level so as to ascertain the security of the network. The more ubiquitous penetration testing becomes the more likely secure most organizations become. This paper demonstrates how to use banner grabbers and packet sniffers to collect important information related to security issues at the corporate level. Experiment on the use of banner grabbers and packet sniffers were carried out and the results are discussed. Recommendations are made to motivate organizations to use these tools in order to improve organizational preparedness in performing penetration testing, hence improving network security.
