The Wireshark traffic capture exhibits a pattern where a single source IP address is sending a series of SYN packets to a single destination IP address. This pattern is indicative of a SYN flood attack, which is a form of Denial-of-Service (DoS) attack. In a SYN flood attack, the attacker exploits the TCP handshake mechanism by sending a flood of SYN packets to the target’s IP address. Theattacker does not complete the handshake with an ACK after receiving a SYN-ACK from the server, leaving connections half-open and eventually exhausting the server’s resources, which can lead to denial of service.

The Cisco CyberOps curriculum, particularly the courses on Performing CyberOps Using Cisco Security Technologies (CBRCOR), would cover the identification and analysis of network threats, including SYN flood attacks.

Cisco’s official certification resources for the CyberOps Associate level would provide detailed information on various network threats and how to mitigate them, including the mechanisms of a SYN flood attack.
