Question 1 of 30

In a network security analysis scenario, a cybersecurity analyst captures packets from a suspicious network segment. The captured data shows a significant number of TCP packets with the SYN flag set, but very few packets with the ACK flag. The analyst suspects a SYN flood attack. To confirm this, the analyst decides to calculate the SYN to ACK ratio over a specific time window of 10 seconds, where 150 SYN packets and 10 ACK packets were recorded. What is the SYN to ACK ratio, and what does this indicate about the nature of the traffic?

15:1, indicating a potential SYN flood attack

5:1, suggesting normal traffic behavior

1.5:1, indicating a balanced connection establishment

10:1, suggesting a minor anomaly in traffic
