توضیحاتی در مورد کتاب عملی آشپزی امنیت لینوکس
امنیت سیستم فایل را افزایش دهید و در مورد حمله شبکه، ابزارهای امنیتی و نسخه های مختلف ساخت لینوکس بیاموزید. ویژگی های کلیدی دستور العمل های عملی برای ایجاد و مدیریت یک سیستم لینوکس ایمن افزایش امنیت سیستم فایل و احراز هویت محلی و از راه دور کاربر استفاده از ابزارهای امنیتی مختلف و نسخه های مختلف لینوکس برای کارهای مختلف شرح کتاب در چند سال گذشته، امنیت سیستم پیشرفت زیادی کرده است. تکانه و متخصصان نرم افزار به شدت روی آن تمرکز کرده اند. لینوکس اغلب به عنوان یک سیستم عامل بسیار امن در نظر گرفته می شود. با این حال، واقعیت این است که لینوکس دارای نقایص امنیتی است، و این نقص‌های امنیتی به مهاجمان اجازه می‌دهد تا به سیستم شما وارد شوند و داده‌های مهم شما را تغییر دهند یا حتی از بین ببرند. اما نیازی به وحشت نیست، زیرا مکانیسم‌های مختلفی وجود دارد که توسط آن‌ها می‌توان این نقص‌ها را برطرف کرد، و این کتاب به شما کمک می‌کند تا با انواع مختلف امنیت لینوکس آشنا شوید تا سیستم لینوکس ایمن‌تری ایجاد کنید. با رویکرد دستور العمل گام به گام، کتاب با معرفی تهدیدات مختلف سیستم های لینوکس شروع می شود. سپس، این کتاب شما را در سفارشی سازی هسته لینوکس و ایمن سازی فایل های محلی راهنمایی می کند. در مرحله بعد، به مدیریت احراز هویت کاربر به صورت محلی و از راه دور و کاهش حملات شبکه خواهید رفت. بعداً با امنیت برنامه و آسیب پذیری های هسته آشنا خواهید شد. همچنین با اصلاح آسیب‌پذیری Bash، فیلتر کردن بسته‌ها، رسیدگی به حوادث و نظارت بر گزارش‌های سیستم آشنا خواهید شد. در نهایت، با ممیزی با استفاده از خدمات سیستم و انجام اسکن آسیب پذیری در لینوکس آشنا خواهید شد. در پایان این کتاب، شما می توانید سیستم های لینوکس خود را ایمن کنید و یک محیط قوی ایجاد کنید. آنچه یاد خواهید گرفت درباره آسیب پذیری ها و سوء استفاده ها در رابطه با سیستم های لینوکس بیاموزید پیکربندی و ساخت یک هسته امن و آزمایش آن درباره مجوزهای فایل و نحوه تغییر ایمن فایل ها اطلاعات کسب کنید. انجام اسکن آسیب‌پذیری در ماشین‌های لینوکس با استفاده از ابزارها درباره اسکن بدافزار بیاموزید و از طریق گزارش‌ها بخوانید این کتاب برای چه کسی است این کتاب برای همه آن دسته از کاربران لینوکس در نظر گرفته شده است که قبلاً درباره سیستم‌های فایل لینوکس و مدیریت اطلاعات دارند. شما باید با دستورات اصلی لینوکس آشنا باشید. درک امنیت اطلاعات و خطرات آن برای سیستم لینوکس نیز برای درک آسان تر دستور العمل ها مفید است.

Enhance file system security and learn about network attack, security tools and different versions of Linux build. Key Features Hands-on recipes to create and administer a secure Linux system Enhance file system security and local and remote user authentication Use various security tools and different versions of Linux for different tasks Book Description Over the last few years, system security has gained a lot of momentum and software professionals are focusing heavily on it. Linux is often treated as a highly secure operating system. However, the reality is that Linux has its share of security flaws, and these security flaws allow attackers to get into your system and modify or even destroy your important data. But there's no need to panic, since there are various mechanisms by which these flaws can be removed, and this book will help you learn about different types of Linux security to create a more secure Linux system. With a step-by-step recipe approach, the book starts by introducing you to various threats to Linux systems. Then, this book will walk you through customizing the Linux kernel and securing local files. Next, you will move on to managing user authentication both locally and remotely and mitigating network attacks. Later, you will learn about application security and kernel vulnerabilities. You will also learn about patching Bash vulnerability, packet filtering, handling incidents, and monitoring system logs. Finally, you will learn about auditing using system services and performing vulnerability scanning on Linux. By the end of this book, you will be able to secure your Linux systems and create a robust environment. What you will learn Learn about vulnerabilities and exploits in relation to Linux systems Configure and build a secure kernel and test it Learn about file permissions and how to securely modify files Authenticate users remotely and securely copy files on remote systems Review different network security methods and tools Perform vulnerability scanning on Linux machines using tools Learn about malware scanning and read through logs Who this book is for This book is intended for all those Linux users who already have knowledge of Linux file systems and administration. You should be familiar with basic Linux commands. Understanding information security and its risks to a Linux system is also helpful in understanding the recipes more easily.
