| Abstract [eng] |
The security of web application is an integral part of ensuring the safety of humans and their data in today's increasingly connected world. Web-based systems are often a target to cyber attacks, thus vulnerability testing is a critical process in computer systems and networks security. Automated scanners, two of which been chosen for the thesis, ZAP and N-Stalker, have been an effective tool for identifying vulnerabilities in cost-less and timely manner. This thesis presents a study of the use of automated scanners on 100 websites within educational institutions. It can be challenging to determine which tool is best suited for a particular testing scenario, therefore the comparison between the scanners was done using clustering methods of DBSCAN, K-Means and Gaussian Mixture. Therewithal scaling and dimensionality reduction of t-SNE and MDS were applied for better implications and visualizations of the data. An observation occurred that DBSCAN provided highest Silhouette Scores and Calinksi-Harabasz index, thus performing better than K-Means and Gaussian Mixture algorithms. It was also concluded that from 56\% to 92\% of websites fell into same clusters, across the three clustering algorithms, illustrating the similarities between the scanner vulnerability detection. |
