  cidr notation cheat sheet: Internet Routing with BGP Iljitsch van Beijnum, 2022-10-21 The internet is “a network of networks”. It’s made up of tens of thousands of largely independent networks, but somehow the users of one network can communicate with the users of any of the other networks. The Border Gateway Protocol (BGP) is the glue that binds these disparate networks together. BGP is a routing protocol: its main job is to allow each network to learn which ranges of IP addresses are used where, so packets can flow along the correct route. However, BGP has a more difficult job to do than other routing protocols. Yes, it has to make the packets reach their destination, but BGP also has to pay attention to the business side: those packets only get to flow over a network link if either the sender or the receiver pays for the privilege. This book covers the fundamentals of the technical side of BGP, and also looks at the intersection between the technical and business aspects of internet routing. The book contains 40 configuration examples that readers can try out on their own computer in a “BGP minilab”.

  cidr notation cheat sheet: Wireshark for Security Professionals Jessey Bullock, Jeff T. Parker, 2017-03-20 Master Wireshark to solve real-world security problems If you don’t already use Wireshark for a wide range of information security tasks, you will after this book. Mature and powerful, Wireshark is commonly used to find root cause of challenging network issues. This book extends that power to information security professionals, complete with a downloadable, virtual lab environment. Wireshark for Security Professionals covers both offensive and defensive concepts that can be applied to essentially any InfoSec role. Whether into network security, malware analysis, intrusion detection, or penetration testing, this book demonstrates Wireshark through relevant and useful examples. Master Wireshark through both lab scenarios and exercises. Early in the book, a virtual lab environment is provided for the purpose of getting hands-on experience with Wireshark. Wireshark is combined with two popular platforms: Kali, the security-focused Linux distribution, and the Metasploit Framework, the open-source framework for security testing. Lab-based virtual systems generate network traffic for analysis, investigation and demonstration. In addition to following along with the labs you will be challenged with end-of-chapter exercises to expand on covered material. Lastly, this book explores Wireshark with Lua, the light-weight programming language. Lua allows you to extend and customize Wireshark’s features for your needs as a security professional. Lua source code is available both in the book and online. Lua code and lab source code are available online through GitHub, which the book also introduces. The book’s final two chapters greatly draw on Lua and TShark, the command-line interface of Wireshark. By the end of the book you will gain the following: Master the basics of Wireshark Explore the virtual w4sp-lab environment that mimics a real-world network Gain experience using the Debian-based Kali OS among other systems Understand the technical details behind network attacks Execute exploitation and grasp offensive and defensive activities, exploring them through Wireshark Employ Lua to extend Wireshark features and create useful scripts To sum up, the book content, labs and online material, coupled with many referenced sources of PCAP traces, together present a dynamic and robust manual for information security professionals seeking to leverage Wireshark.
