tcpflow Essentials
"tcpflow Essentials" "tcpflow Essentials" provides a comprehensive and authoritative guide to one of the most versatile open-source tools for network forensics and packet-based analysis. Spanning the historical evolution, foundational principles of TCP stream reconstruction, and essential legal considerations, the book thoroughly frames tcpflow’s unique strengths within the broader ecosystem of network monitoring tools such as Wireshark, tcpdump, and Zeek. Through detailed, real-world use cases, readers gain contextual understanding of tcpflow’s capabilities and its role in modern cybersecurity investigations. Moving seamlessly from theory to practice, this text equips the reader with in-depth, hands-on expertise in installing, configuring, and optimizing tcpflow across diverse platforms and deployment scenarios. It explores the tool’s command-line usage, output formats, and advanced features for capturing, filtering, and managing high-volume traffic. Through a deep dive into tcpflow’s architecture—including memory management, flow reassembly algorithms, and extensibility—the book prepares practitioners to address even the most challenging scenarios, such as analyzing fragmented packets or developing custom protocol parsers. Emphasizing real-world relevance, "tcpflow Essentials" dedicates extensive coverage to security operations, incident response, and compliance. Readers discover workflows for integrating tcpflow in automated pipelines, enriching forensic analysis, and scaling deployments for high-bandwidth and cloud-native environments. The book concludes with forward-looking perspectives on encrypted traffic, big data integration, and the emergence of AI-driven analysis, making it an indispensable reference for both network defenders and contributors to the tcpflow open-source community.

Explore virtualized networking environments through the Cloud, Edge, and 5G core networks, and their applications. This book covers the primary approaches related to setting up and experimenting with related cloud and networking environments using virtual networks, and virtual network functions. You’ll start by experimenting with future networking environments and learn a variety of Docker basics and essential networking skills. Specifically, containers, networking, volumes, iptables (for Docker environment security) and default orchestration features are discussed to help set up custom cloud, edge, and 5G core networking environments. Hands-on activities related to Docker networking and services features for publishing, scaling, and monitoring of services are also provided. By the end of Part 1, you’ll be able to set up a variety of custom networking environments easily using Docker compose features and secure the set-up using iptables. Part 2 introduces Network Function Virtualization (NFV) architecture, and its roles in Cloud and 5G core networks. You’ll learn to deploy an open source 5G core platform from OpenAirInterface (OAI) using Docker. Then, you’ll set up and evaluate Virtual Network Functions (VNF) over suitable virtual networks. Hands-on activities are featured to guide you through the process of setting up and deploying VNFs such as DHCP, DNS, and proxy servers. Finally, Part 3 discusses key virtual networks such as IP VLANs, MAC VLANs, and overlay networks using Docker cluster setups. You’ll use interesting hands-on activities to easily experiment and learn cloud and 5G core network set-up related virtual networks, overlay networks, and network slicing. When done, you’ll be able to set up a variety of VNFs, carefully deploying VNFs, and conducting slicing activities over Docker cluster setups. What You’ll Learn Explore Cloud, Edge, and 5G core networking using Docker networking features. Build and evaluate a variety of virtual networks and deploy Virtual Network Functions (VNFs) and Network Slices using Docker swarm setups. Set up and deploy an open source 5G core network using Docker for experimenting. Enhance cloud environment and applications security using linux security features such as Capabilities, Seccomp, and AppArmors. Develop and evaluate network security experiments using Scapy and Docker networks. Who This Book Is For Network engineers, cloud engineers, students, faculty, and cloud and networking researchers.
