In this post, we'll delve into the depths of Wireshark, unraveling its mysteries through master-level questions and expert solutions. So, let's embark on this journey to enhance your understanding and ace your assignments!

Understanding Wireshark Filters:
One common challenge students encounter when using Wireshark is filtering packets effectively. Let's explore a scenario where you're tasked with capturing HTTP traffic originating from a specific IP address within a given time frame.

Question:
How can you set up a Wireshark filter to capture HTTP traffic originating from IP address 192.168.1.100 between 9:00 AM and 12:00 PM on May 9, 2024?

Solution:
To accomplish this task, follow these steps:
1. Open Wireshark and start capturing packets.
2. In the filter toolbar, enter the following filter expression:
   ```
   ip.src == 192.168.1.100 && http && frame.time >= "May 9, 2024 09:00:00" && frame.time <= "May 9, 2024 12:00:00"
   ```
3. Press Enter to apply the filter.
4. Wireshark will now display only HTTP traffic originating from the specified IP address within the designated time frame.

Analyzing ARP Spoofing Attacks:
Another critical aspect of network security is identifying and mitigating ARP spoofing attacks. Let's consider a scenario where you suspect ARP spoofing on your network and need to analyze ARP packets to confirm the attack.

Question:
How can you use Wireshark to detect ARP spoofing attacks and identify the spoofed MAC addresses?

Solution:
To detect ARP spoofing attacks and identify spoofed MAC addresses using Wireshark, follow these steps:
1. Start Wireshark and begin capturing packets on the network interface experiencing suspicious activity.
2. Apply a filter to display only ARP packets by entering "arp" in the filter toolbar.
3. Look for ARP packets where the source MAC address (SMAC) does not match the MAC address associated with the IP address in the destination field (DMAC). These inconsistencies indicate potential ARP spoofing.
4. Note down the IP addresses and corresponding MAC addresses involved in the suspicious ARP packets.
5. Use network topology information to verify the legitimacy of the MAC addresses associated with the IP addresses.
6. If discrepancies are found, investigate further to identify the source of the ARP spoofing attack and implement appropriate countermeasures.
