Wireshark 101: Understanding the User Dashboard and Basis Customization:

Wireshark Menu Bar: Beginner Friendly Menus

Let’s take a deep dive into understanding the function of each icon and how one can utilize them for better optimization of the Wireshark tool.

Wireshark's File Menu:

Wireshark's File Menu offers various tools for managing captured files, including opening, closing, and saving them. One of the most important features within this Menu is the Export feature, which allows users to save specific packets or packet dissections in various formats.

Key Export Options:

1. Export Specified Packets: This option lets you save selected packets from a capture file. It's useful for trimming irrelevant or unwanted packets. You can choose the range of packets to export and the format in which to save them.
2. Export Packet Dissections: This feature allows you to save packet details in different formats such as plain text, CSV, JSON, and XML. You can customize the export by selecting specific packet details and formats.
3. Export Objects: This option enables you to export captured objects like DICOM, FTP-DATA, HTTP, IMF, SMB, or TFTP into local files

Wireshark’s Edit Menu:

The Edit Menu is embedded with various tool that one can use to customize Wireshark suit preference or use, this feature allows one narrow down search and make a cleaner dashboard during investigation troubleshooting or as the case may be. We will be spotlighting a few relevant feature within the Edit Menu that can boost user effectiveness. Key Edit Menu Options:

1.???? Find Packet:

o?? This feature allows users to find packets using Display Filter, Strings, Hex value, or Regular Expression. This helps narrow down searches to specific relevant packets.

o?? The String option is flexible for beginners, allowing the search for specific strings within packets.

?

2.???? Profile Configuration:

o?? The features allows users to create new profile within Wireshark and all changes made during investigation would be saved to that profile. Wireshark is set to default profile, but for a more personalized experience this feature is recommended.

o?? Profile can be set to fit different need, so a user can have multiple profile, uniquely customized.

3.???? Preference:

?

o?? The Appearance option allows users to customize the Wireshark dashboard for easy navigation.

o?? It enables users to understand what each colorization represents.

o?? The Name Resolution option gives users the flexibility of resolving names in captured packets. They can resolve names using the MAC address, Transport Name, or Network (IP) address.

Other features within the Edit Menu you can explore include Mark/Unmark Selected, Mark All Selected, Ignore/Unignore Selected, Ignore All Selected, and Time Shift. These features help users narrow their search to display only the packet information relevant to their investigation.

Wireshark View Menu:

?

The View Menu is your gateway to customizing the dashboard to suit your needs. With a variety of options, you can tailor the interface to display only the most relevant features, enhancing both visualization and efficiency. Here are so Menu of the features you can show or remove:

·??????? Main Toolbar

·??????? Status Bar

·??????? Filter Toolbar

·??????? Full Screen

·??????? Packet Details

·??????? Packet List

·??????? Packet Bytes

·??????? Packet Diagram

The View Menu isn't just about aesthetics; it's about optimizing your workflow, improving focus, and boosting productivity.

?While these options enhance visualization by displaying relevant features, let's dive into three key features that can significantly boost your efficiency:

Colorize

The Colorize feature allows you to apply color rules to packets, making it easier to identify and differentiate between various types of traffic. This visual aid can help you quickly spot anomalies or specific patterns in your network data.

o?? Wireshark comes with its own default colorization rule of which is highly flexible and can be adjusted.

Time Display Format

This feature lets you customize how timestamps are displayed in your packet list. You can choose from several formats, such as absolute time, relative time, or delta time, depending on what best suits your analysis needs. Adjusting the time display format can provide better context and clarity when reviewing packet sequences.

Internals

The Internals option provides insights into Wireshark's internal workings, such as protocol dissection and memory usage, conversation hash Table, list of support protocols and the fields within dissectors. This is a good avenue to learn new protocols and stay ahead of the curve while improving your analytic skills

This feature is particularly useful for advanced users who want to understand the underlying processes and optimize their Wireshark performance.

Wireshark Go Menu:

The "Go" feature in Wireshark allows users to navigate through packets in a capture file efficiently. Here are the key options it entails:

o?? Back: allows user navigate to the recently visited packet in the packet history.

o?? Forward: Move to the next visited packet in the packet history.

o?? Go to Packet: this feature allows user Specify a packet number and jump to that packet.

o?? Go to Corresponding Packet: Navigate to the corresponding packet of the currently selected protocol field.

o?? Previous Packet: Move to the previous packet in the list.

o?? Next Packet: Move to the next packet in the list.

o?? First Packet: Jump to the first packet of the capture file.

o?? Last Packet: Jump to the last packet of the capture file.

o?? Previous Packet in Conversation: Move to the previous packet in the current conversation.

o?? Next Packet in Conversation: Move to the next packet in the current conversation.

o?? Auto Scroll in Live Capture: Automatically scroll the packet list pane as new packets come in.

Wireshark Capture filter:

The capture feature in Wireshark is crucial for determining whether packets will be captured and from which interface. Proper configuration of the capture settings ensures that Wireshark can effectively monitor and analyze network traffic. This includes selecting the correct network interface and setting appropriate capture filters to focus on the relevant packets. Some features within the capture menu includes;

o?? Start: Initiate the capture packets process over a selected interface. Once started it enables Wireshark to capture in real-time packet that flow over the specified interface.

o?? Stop: This option halt ongoing capture process. This is useful where enough packet have been captured or need to pause to collect packet for analysis.

o?? Restart: Stops the current packet capture and immediately starts a new capture session on the same interface.

?

Option:

The "Option" feature within the Capture menu in Wireshark is crucial for configuring how packets are captured. Here are the key points:

o?? Interface Selection: Choose the network interface from which packets will be captured.

Note: Wireshark allow for multiple selection of interface. This feature enables users to capture packets from multiple network interfaces simultaneously.

o?? Capture Filter: Set filters to capture only specific types of traffic, reducing the amount of data collected.

o?? Promiscuous Mode: promiscuous mode ensures that all network traffic on the network segment is captured, regardless of whether the packets are addressed to the host capturing the packets or not. This mode allows the network interface to intercept and read all packets, making it possible to capture traffic within the entire network segment.

o?? Buffer Size: Adjust the buffer size for capturing packets to prevent packet loss during high traffic.

Remember Master your skills, raise the bar, and stay ahead of the curve. See you in the next edition!
