1CYBER SECURITYAnswer to question 1This main objective of this paper is to describe an enhancing factor of the NetSPA attackgraph system. This system will be used to model all the threats that are persistent in the presentday scenario which includes client-sided attacks and the zero-day exploits. This paper alsodiscusses about the countermeasures to be included for addressing the mitigation of these threats.These countermeasures are host-based vulnerability scanning, personal and proxy firewalls andintrusion prevention system. Answer to question 2The author of this paper wants to address the detection of the network related risks thatare persistent in the present day lives of any system. By measuring the risks involved in any kindof enterprise based networks, the attacks graphs can utilize the network defenders forunderstanding the various threats related to them and also apply the effective countermeasureneeded for mitigating them. Answer to question 3This paper has utilized the adoption of NetSPA which is an effective program thatcaptures the attacks graph for modeling the adversaries and effects related to the application ofthe countermeasures. The working of this program is based on the scanning of the whole networkby utilizing network vulnerability scans and firewall rules (Ingols et al. 2009). In addition, in thispaper, for modeling all the attack related requirements, the network was scanned according to therequirements. The network-based scans were utilized to find the vulnerabilities on client-sidedattacks. For modeling zero-day attacks, this paper has hypothesized various vulnerabilities.
