As a Computer Hacking Forensics Investigator, you are analyzing a TCP dump of network traffic during a suspected breach. During the investigation, you noticed that the “Packets dropped by kernel” count was unusually high. Given that the network has a high load, what could be the most probable reason for this situation?

  • A. The Tcpdump tool was run without the -c flag, causing it to capture packets indefinitely
  • B. The TCP packets were not matching the input expression of Tcpdump
  • C. The Boolean expression used with Tcpdump was too restrictive, missing some packets
  • D. The buffer space in the OS running Tcpdump was insufficient, leading to dropped packets

Selected Answer: D
Packets “dropped by kernel” is the number of packets that were dropped due to a lack of buffer space, by the packet capture mechanism in the OS running Tcpdump, if the OS reports that information to applications; if the information is not reported, it will be reported as 0
