What is Wireshark

In this chapter, an analysis of security attacks on network elements along with the appropriate countermeasures is presented. The main goal of this chapter is to present the practical execution of various security attacks and their mitigation techniques due to more resilient cyber infrastructure. The network topology that has been attacked is designed in GNS3 software tool installed on Windows operating system, while the attacks are performed in Kali Linux operating system. Three groups of security attacks (Denial of Service, Man in the Middle, and Control Plane attacks) are observed in simulation scenarios with a detailed analysis on each of them, followed by a presentation of practical performance and ways of prevention (protection) against the attacks.
