Download or read book Wireshark for Security Professionals written by Jessey Bullock and published by John Wiley & Sons. This book was released on 2017-03-20 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 101 Labs - Book Series Experts agree that we retain only 10% of what we read but 90% of what we do. Perhaps this explains why the global pass rate for most IT exams is a ghastly 40%. This is where the 101 Labs book series can help. We are revolutionizing how IT people train for their exams and the real world with our Learn - By - Doing teaching method. 101 Labs' mission is to turn you into an IT expert by doing instead of reading. Using free software and free trials, our experts take you by the hand and walk you through every aspect of the protocols and technologies you will encounter in your IT career. We share our configuration tips and tricks with you as well as how to avoid the common mistakes many novice engineers make, which can quickly become career-ending. 101 Labs - CompTIA Network] This book is designed to help you pass the new N10-007 exam. It now features Performance-based questions (PBQs). These questions test your configuration and troubleshooting skills and add a new level of complexity to the exam. The only way to answer these types of questions is to have hands-on experience with the protocols and technology listed in the exam syllabus. The Network+ exam is probably the most useful exam in the IT industry. It equips you with all the necessary knowledge you need in order to work with other IT professionals and work in the IT industry. You learn TCP/IP, security, networking protocols and standards, best practices, subnetting and IP addressing, IPv6, troubleshooting tools and software, security, wireless, routing protocol basics, and much more. CompTIA presumes around 9-12 months of on-the-job experience for all of its exams, but of course, most of the students who take the exam don't have this. Even if they are working in IT roles, such as in helpdesk or server support, they will have been exposed to only a tiny number of the skills tested in the exam. Doing all the labs in this book will give you that experience. Please use the free resources at www.101labs.net/resources which will help you with the labs.

Available in PDF, EPUB and Kindle. Book excerpt: A field manual on contextualizing cyber threats, vulnerabilities, and risks to connected cars through penetration testing and risk assessment Hacking Connected Cars deconstructs the tactics, techniques, and procedures (TTPs) used to hack into connected cars and autonomous vehicles to help you identify and mitigate vulnerabilities affecting cyber-physical vehicles. Written by a veteran of risk management and penetration testing of IoT devices and connected cars, this book provides a detailed account of how to perform penetration testing, threat modeling, and risk assessments of telematics control units and infotainment systems. This book demonstrates how vulnerabilities in wireless networking, Bluetooth, and GSM can be exploited to affect confidentiality, integrity, and availability of connected cars. Passenger vehicles have experienced a massive increase in connectivity over the past five years, and the trend will only continue to grow with the expansion of The Internet of Things and increasing consumer demand for always-on connectivity. Manufacturers and OEMs need the ability to push updates without requiring service visits, but this leaves the vehicle’s systems open to attack. This book examines the issues in depth, providing cutting-edge preventative tactics that security practitioners, researchers, and vendors can use to keep connected cars safe without sacrificing connectivity. Perform penetration testing of infotainment systems and telematics control units through a step-by-step methodical guide Analyze risk levels surrounding vulnerabilities and threats that impact confidentiality, integrity, and availability Conduct penetration testing using the same tactics, techniques, and procedures used by hackers From relatively small features such as automatic parallel parking, to completely autonomous self-driving cars—all connected systems are vulnerable to attack. As connectivity becomes a way of life, the need for security expertise for in-vehicle systems is becoming increasingly urgent. Hacking Connected Cars provides practical, comprehensive guidance for keeping these vehicles secure.
