Enhancing Network Security: Wireshark-Based Anomaly Detection for Flooding Attacks (2018)

This dissertation aims to explore the capabilities of Wireshark in identifying network flooding attacks. Wireshark employs anomaly detection technologies within its packet analyzer to detect flooding attacks, characterized as assault techniques on computer networks. In such attacks, assailants send various surges to users or administrators, intending to disrupt the network framework. Types of flooding assaults include UDP surges, ping surges, and Syn surges.

Various challenges are associated with ping surge scenarios, utilizing ping commands to operate the framework, and the delivery of Wireshark. This includes establishing a casualty that quantifies the number of ping parcels received within a predefined time period associated with the flooding attack under study. The TCP SYN flood, commonly known as a Distributed Denial of Service (DDoS) attack, exploits the standard three-way handshake of TCP, consuming all resources of the target server and rendering it unresponsive.

In flooding attacks, the three-way handshake mechanism of TCP is exploited, leading to limitations in maintaining half-open connections. When a server receives a SYN request, it responds with a SYN/ACK packet (known as SYN acknowledgement) to the client. The connection remains in a half-open state until the client acknowledges the SYN/ACK packet, or the TCP connection times out, usually lasting for 75 seconds. Each server has a finite-size backlog queue in its system memory to maintain these half-open connections. However, when the backlog queue is full, all connections are dropped.
