In this post, we delve into the depths of network analysis, presenting master-level questions alongside expert solutions crafted by our seasoned professionals.

Question 1: Analyzing Network Traffic Patterns

Consider a scenario where a network administrator suspects unusual activity on a local network segment. As part of the investigation, you are tasked with analyzing network traffic using Wireshark. Identify the following:

a) Top three protocols consuming the highest bandwidth.
b) Any anomalous patterns or irregularities in the traffic flow.
c) Possible sources or destinations of the suspicious activity.

Solution:

a) To identify the top three protocols consuming the highest bandwidth, navigate to the Statistics menu in Wireshark and select Protocol Hierarchy. Sort the protocols based on bytes or packets to determine the most bandwidth-intensive protocols.

b) Look for anomalies such as unusually high traffic volume from specific IP addresses, unusual port activity, or unexpected protocol usage. Use Wireshark's filtering capabilities to isolate suspicious packets for closer inspection.

c) Trace the source and destination IP addresses associated with the anomalous activity. Cross-reference these addresses with network logs or user accounts to identify potential sources of the suspicious traffic.

Question 2: Detecting Network Intrusions

In a corporate network environment, detecting and mitigating intrusions is paramount to ensuring data security. You are tasked with analyzing network traffic captured during a suspected intrusion attempt. Outline the steps to identify and analyze the intrusion using Wireshark.

Solution:

1. Start by filtering the captured packets to isolate traffic relevant to the suspected intrusion. Use Wireshark's display filters to focus on specific IP addresses, ports, or protocols associated with the incident.
2. Look for signs of malicious activity such as port scanning, packet fragmentation, or unusual protocol behavior. Pay close attention to any traffic patterns indicative of reconnaissance or exploitation attempts.
3. Analyze packet payloads for suspicious content, including known attack signatures, command-and-control communication, or data exfiltration attempts. Wireshark's packet details view provides insights into packet contents for deeper analysis.
4. Trace the source of the intrusion back to its origin by examining packet headers and identifying the attacking IP address. Gather additional context from network logs and intrusion detection systems to corroborate your findings.
