Wireshark MASTERY - Work From Home Jobs with WIRESHARK!

Download and install Wireshark from the official site, select the 32 or 64 bit option for the current stable release 2.40.3, enable tshark and winpcap during setup for packet capture.

Master wireshark capture options and quick customization to speed analysis by selecting your network adapter and starting capture with no filters or buffers.

Select the network adapter, enable promiscuous mode, and apply capture filters to isolate traffic; configure rolling buffers and stop conditions for manageable, targeted saves.

Learn to use display filters in Wireshark to hone in on specific packets by IP, subnet, source/destination, ports, and logical and/or operators, speeding up troubleshooting.

Learn to build display filters in Wireshark by inspecting a packet's frame length, preparing a filter for less than 1000 bytes, and applying it to reveal matching packets.

Explore color schemes in Wireshark by applying coloring rules with display filter syntax, adjusting foreground and background, and managing defaults to highlight packets without missing crucial details.

Explore customizable columns and profiles in Wireshark to tailor packet analysis. Learn to create and switch profiles, add columns, and use filter buttons for faster troubleshooting.

Explore how Wireshark's conversations, IO graph, and protocol-specific graphs reveal traffic patterns across IPv4/IPv6, TCP/UDP, DNS, and HTTP, with flow graphs visualizing front-end to back-end traffic.

Explore how TCP establishes reliable connections using the three-way handshake, examines sequence and acknowledgement numbers, and analyzes data transfer and connection closure in Wireshark.

Learn how Wireshark reconstructs http payloads from multiple tcp segments, follows the stream to reveal get requests and http 200 responses, and exports http objects, including encrypted https limitations.

Explore how TLS 1.2 secures HTTPS traffic through the client hello and server hello exchange, cipher suite negotiation, and certificate verification, then observe the encrypted data transfer that follows.

Study dhcp traffic and the bootstrap protocol that dynamically assigns IP addresses and options like domain name server and default gateway, through discover, offer, request, and acknowledgement.

Analyze how DNS translates names to IP addresses and how Wireshark reveals DNS queries, responses, and record types such as A, Quad A, PTR, host, text, and MX.

Tshark, the command line variant of Wireshark, lets you perform packet captures and analysis from the terminal using interface selection, display filters, and saving to pcap.

Learn how to install Wireshark on Windows, choose the correct 64-bit or 32-bit installer, install Npcap for packet capture, set up a desktop icon, and associate files for seamless capture.

Learn to configure Wireshark captures by selecting interfaces, applying capture filters and display filters, and saving or discarding traffic to aid troubleshooting.

Master display and capture filters in Wireshark to target IP addresses, IP source, and IP destination. Build and apply port filters like 80 and 443 using or and saved filters.

Explore how Wireshark uses color and filters to highlight packets, view coloring rules, add or remove rules, and learn how rule order and foreground/background colors affect what you see.

Explore Wireshark statistics to view conversations, endpoints, and protocol-specific data (IPv4, IPv6, TCP, UDP) and learn to apply filters, use IO graphs, and visualize DNS and HTTP traffic.

Capture and analyze DNS traffic in Wireshark by filtering for DNS over UDP, inspect protocol layers and headers, and analyze DNS queries such as google.com.

Capture and filter http traffic in Wireshark by starting a capture for Microsoft.com using an http tcp port 80 capture filter, then filter by IP address to isolate 30 packets.

Capture email traffic with Wireshark on port 25 and review smtp handshakes, including the three-way tcp handshake. Observe that after negotiating tls, the content becomes encrypted, illustrating secure mail communication.

Learn to use tshark, the command-line companion to Wireshark, to capture DNS traffic, filter by port 53, and extract domain names for diagnosing suspicious activity and tuning firewall rules.
