Port Scanning: Techniques, Tools and Detection

Abstract

In cyber security, it has long been understood that some cyber security procedures can be utilised for malicious purposes as well as cyber defence. The focus of this paper lies on one such procedure called port scanning. In port scanning, vulnerabilities are discovered through searching hosts and networks for open ports and closed ports. In this paper, a thorough analysis of modern port scanning tools, techniques and detection methods is presented. Finally, this paper will discuss and propose an argument for the implementation of one specific port scanning detection technique aside from any other techniques.
