- Basics of file management: saving captures, opening files, and exporting data.
Module 2: Packet Capturing Basics
- Starting a Capture
- Selecting the appropriate network interface for capture.
- Starting and stopping packet capture.
- Understanding capture buffers and file sizes.
- Capture Filters
- What are capture filters?
- Common capture filters (e.g., capturing specific protocols, IP addresses, ports).
- Using BPF (Berkeley Packet Filter) syntax.
- Working with Capture Files
- Saving capture files (.pcap, .pcapng) for later analysis.
- Opening and reviewing previously captured data.
Module 3: Display Filters and Data Analysis
- Introduction to Display Filters
- What are display filters, and how do they differ from capture filters?
- Basic display filter syntax (e.g.,
ip.addr
,tcp.port
,http
). - Examples of practical display filters (filtering based on IP address, protocol, and port).
- Understanding Wireshark’s Filter Expression Language
- Combining multiple filters using logical operators (
and
,or
,not
). - Using Wireshark’s auto-complete feature to build complex filters.
- Using the filter toolbar for quick access to common filters.
- Combining multiple filters using logical operators (
- Packet Details and Interpretation
- Analyzing individual packet details.
- Understanding packet structure (headers, payload, and protocols).
- Identifying protocol-specific fields (e.g., TCP flags, HTTP request methods, DNS queries).
Module 4: Protocol Analysis
- TCP/IP Protocols
- Breaking down the TCP/IP model and understanding its layers (Link, Internet, Transport, and Application).
- In-depth analysis of common protocols like TCP, UDP, and ICMP.
- Application Layer Protocols
- Analysis of HTTP, FTP, DNS, SMTP, and other application-layer protocols.
- How to identify issues related to each protocol using Wireshark.
- Detailed analysis of web traffic, DNS queries, and FTP file transfers.
- Troubleshooting Network Traffic
- Identifying retransmissions, latency, and packet loss.
- Recognizing network errors and misconfigurations.
- Analyzing round-trip times (RTT), sequence numbers, and window sizes.
Module 5: Advanced Wireshark Features
- TCP Stream Analysis
- Following a TCP stream to reconstruct data flow.
- Analyzing application data and performance metrics (e.g., throughput, response times).
- Reassembly of Protocols
- Reassembling fragmented IP packets.
- Handling and interpreting fragmented data from applications like HTTP or DNS.
- Coloring Rules and Profiles
- Customizing display with coloring rules for quick identification of traffic types.
- Creating custom profiles for different types of network analysis (e.g., troubleshooting, security).
Module 6: Network Security and Threat Detection
- Using Wireshark for Security Analysis
- Identifying signs of malicious traffic and attacks (e.g., DoS, DDoS, buffer overflows).
- Understanding common security-related network traffic (e.g., port scanning, malware communications).
- Analyzing Encrypted Traffic
- Identifying SSL/TLS handshake processes.
- How to analyze encrypted sessions and identify potential security issues.
