Post Views: 1,915 I provide this information for reference when examining TLS in Wireshark. The TLS 1.2 protocol ladder (also called the TLS handshake ladder) describes the step-by-step sequence of message exchanges between a client and server as they negotiate a secure, encrypted connection. Think of it as a “ladder” where each side alternates rungs

Post Views: 8,301 Using a loopback adapter (also called a local loopback interface) for packet capture in Wireshark allows you to capture traffic that stays within your own computer — for example, packets exchanged between local applications via localhost or 127.0.0.1. Normally, this traffic never reaches a physical network interface, so a loopback capture is

Post Views: 3,944 Many technicians and network engineering staff, as well as IT staff, often need to “tap” into the Ethernet to capture and troubleshoot network traffic. A full-duplex tap (also called a network tap) is a hardware device placed inline on an Ethernet link that allows network engineers to capture all traffic traveling in

Post Views: 6,888 I am a ChatGPT subscriber to the basic (not PRO) service. I saw the following post on LinkedIn and was fascinated: Think about the implications. You don’t need to know how to use Wireshark other than to do a capture. You certainly don’t need to know how to troubleshoot packet captures as

Post Views: 2,787 Great question. In one sentence it is a purple tool, meaning both! Wireshark itself is a passive tool, it is non-intrusive — it doesn’t create attacks — but it’s a force multiplier for both Red and Blue Teams depending on who controls the capture point and how the data is used. Let

Post Views: 3,548 RFMON stands for Radio Frequency MONitor mode. It is a special mode for wireless network interfaces that allows a device to capture all radio traffic it can receive on a wireless channel, regardless of the intended recipient. All Wi-Fi radios can go into different modes, but that does not mean you can
Post Views: 3,419 As a frequent reader here will know, my Wi-Fi Analyzer of choice is called WinFi. It has been around many years as is fabulous. In version 2, and the new version 3, you can capture Wi-Fi Beacon Frames and examine them. This post will explain what you can capture and how this

Post Views: 48,072 In this tutorial I am going to make you a pro at using and leveraging the Wireshark TCP Graphing tools. As many of you who have taken my Wireshark Courses know, I am a big fan of visualizing what is going on in a given packet capture or conversation. My #2 troubleshooting

Post Views: 13,781 A Wireshark TCP Analysis Flags cheat sheet is essential because TCP is the foundation of most modern network communications, and Wireshark’s built-in TCP Analysis engine automatically identifies performance problems, retransmissions, latency conditions, packet loss, flow-control issues, and connection anomalies that would otherwise require deep manual packet inspection. For many users, the TCP

Post Views: 6,797 As QUIC has emerged to begin its takeover of the Transport Layer (OK – we will never see TCP totally disappear), I have written multiple articles on QUIC. You can look them over here. In the early days Google made this really easy right within the Chrome web browser. As time has

Post Views: 2,883 Let’s start with some simple definitions of these protocols and how they work together. In Voice over IP (VoIP) to PSTN (telephone) network integration, MGCP and C15 can work together as part of a layered signaling architecture that bridges IP-based call control with traditional PSTN switching systems. Here’s how they fit and

Post Views: 11,206 Capturing network traffic with VLAN tags on a Windows computer can be tricky due to how network adapters and capture software handle VLAN-tagged frames. By default, Windows often strips VLAN tags before passing packets to capture applications like Wireshark. However, there are ways to configure your setup to properly capture VLAN information.

Post Views: 8,948 So often in Wireshark videos and classes we spend a lot of time on TCP behavior. But what I am about to discuss is hardly ever brought up. The answer to version is simple right? Version 4. OK, kind of right, but overlooking too much. The truth is that there are multiple
