New book Unix/Linux Log Analysis and traffic monitoring is coming soon

The new book "Unix/Linux Log Analysis and traffic monitoring" is about to release the 0.75 million-word book created in three years. It has been approved by the publishing house today and will be published soon. This book provides a comprehensive and systematic explanation of Various Unix/Linux systems and network service logs on the subject of network security, starting from the collection and analysis of the original system logs (RawLog, it gradually goes deep into the log auditing and forensics process. This book provides multiple cases, each of which uses a vivid recording method to describe the network intrusion, the management personnel carry out the system forensics and recovery process, and use case analysis techniques with stories to enable readers to test their emergency response and Computer Forensics capabilities. This book uses various logs, script programs, and other information from the perspective of O & M engineers to handle various system and network faults. It focuses on delivering a solution to the readers, IT also demonstrates the use and deployment of some open-source security tools and delivers a positive energy to the IT practitioners. This book featured a special book with Unix/Linux as the main platform, an open source software as the main analysis tool, and Enterprise Network Security O & M as the background. The selected cases cover typical attack types in today's network applications, such as DDOS, malicious code, Web application attacks, wireless network attacks, and SQL injection attacks, each story first describes all the evidence and evidence of a security event (including log files, topology maps, and device configuration files) and raises some questions to guide readers to analyze the cause of intrusion, at last, I went deep into the case analysis and used detailed evidence to thoroughly explain the ins and outs of the intrusion process. At the end of each case, I proposed preventive measures and remedial measures for such cases. The biggest highlight of this book is to show you how to use the Ossim open-source system to solve in-depth mining of network security issues. This book uses a selection of more than 20 complete cases (the more difficult the stars are) for the majority of readers to share is a real dry goods, it has a great reference value for improving the level of network maintenance and event analysis capabilities. if you pay attention to network security, the cases in this book will surely resonate with you. This book is suitable for reference by experienced network engineers, system administrators, and information security personnel. Previously, the published best-selling book "Linux Enterprise Application Case Analysis" (This book was released in the spring of 2014) is the companion article of log case analysis, this book provides a deeper and multi-angle explanation of the Unix/Linux system and network problems that enterprises are most concerned about. This book shares the experience and joy of operating and maintaining Unix/Linux systems over the past 10 years, the three chapters of the book are as follows: The first log analysis basics

In more than 1000 days and nights of book creation, I started writing at home every day except for work. I recalled my past experiences, sorted out my recent notes, and started my creation. Every night is the most efficient time for my creative inspiration and writing, no one will disturb you at that time, you can devote yourself to it. I'm afraid I can only understand the hardships of writing. I hope that the security log analysis in this book can enlighten the personnel engaged in security O & M.
