With the advent of emerging and complex technologies, traffic capture and analysis play an integral part in the overall IT operation. This book outlines the rich set of advanced features and capabilities of the Wireshark tool, considered by many to be the de-facto Swiss army knife for IT operational activities involving traffic analysis. This open-source tool is available as CLI or GUI. It is designed to capture using different modes, and to leverage the community developed and integrated features, such as filter-based analysis or traffic flow graph view. You'll start by reviewing the basics of Wireshark, and then examine the details of capturing and analyzing secured application traffic such as SecureDNS, HTTPS, and IPSec. You'll then look closely at the control plane and data plane capture, and study the analysis of wireless technology traffic such as 802.11, which is the common access technology currently used, along with Bluetooth. You'll also learn ways to identify network attacks, malware, covert communications, perform security incident post mortems, and ways to prevent the same. The book further explains the capture and analysis of secure multimedia traffic, which constitutes around 70% of all overall internet traffic. Wireshark for Network Forensics provides a unique look at cloud and cloud-native architecture-based traffic capture in Kubernetes, Docker-based, AWS, and GCP environments. What You'll Learn Review Wireshark analysis and network forensics Study traffic capture and its analytics from mobile devices Analyze various access technology and cloud traffic Write your own dissector for any new or proprietary packet formats Capture secured application traffic for analysis Who This Book Is For IT Professionals, Cloud Architects, Infrastructure Administrators, and Network/Cloud Operators

A comprehensive guide to learning container and application hosting capabilities in Cisco platforms, and implementing them to achieve higher efficiency in network deployments and operations Cisco architectures offer comprehensive compute virtualization capabilities to accommodate both native and third-party container hosting, so you can containerize and instantiate any application or network service and gain unprecedented value from your networks. Direct from Cisco, this is the complete guide to deploying and operating containerized application and network services on Cisco platforms. First, the authors review essential virtualization and containerization concepts for all network professionals and introduce leading orchestration tools. Next, they take a deep dive into container networking, introducing Cisco architectural support for container infrastructures. You'll find modular coverage of configuration, activation,orchestration, operations, and application hosting for each key Cisco software platform: IOS-XE, IOS-XR, and NX-OS. The authors explore diverse orchestration tools, including LXC,Docker, and Kubernetes, and cover both Cisco and open-source tools for building and testing applications. They conclude with multiple use cases that show how containerization can improve agility and efficiency in a wide range of network environments. Review the motivation, drivers, and concepts of computing virtualization Learn how Cisco platforms are achieving infrastructure virtualization Explore the Cisco reference model for developing cloud-native services and moving to cloud-native network functions Master Cisco container networking fundamentals, supported modes, and configuration Enable,install, activate, and orchestrate containerized applications in Cisco IOS-XE,IOS-XR, and NX-OS Compare tools and methods for developing, testing, hosting, and orchestrating containerized applications Discover real-world use cases for Day-0, Day-1, and Day-2 operations, with practical deployment examples Preview merging trends in network containerization
