Vulnerability Analysis and Modeling

One of the significant risks of computer systems is the lack of security whether that is attributed to the system vulnerabilities or too sophisticated intrusion techniques. The software security vulnerability is detrimental to the user as well as the system because of its inability to protect confidentiality within the system. Analysis from a national database displays how software vulnerabilities are categorized and how much of an impact they play amongst computer systems. To help preventing attacks, we propose that the focus be more on producing vulnerability free software, rather than focusing on issuing patches. The contribution of this paper is to show the need to include all three methods: prevention, detection and accommodation, to mitigate vulnerabilities. This requires the adoption of formal methods in software development, end user education and vulnerability modeling using the Kill Chain Technique.
