Practical Linux Security Cookbook, 2nd Edition
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 aws, and these security aws 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 aws 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.

TypeScript 3.0 Quick Start Guide
TypeScript is designed for the development of large applications and can be used to develop JavaScript applications for both client-side and server-side execution. This book is the ideal introduction to TypeScript, covering both the basics and the techniques you need to build your own applications. We start by setting up the environment and learning about the build tools that support TypeScript. Then we look at scoping of a variable, and the difference between a undefined variable and a null variable. You will then see the difference between an object, an Object, an object literal, and an object built with a constructor, crucial concepts in understanding TypeScript. You will learn how to make your code more generic to increase the reusability of your classes, functions, and structures, and to reduce the burden of duplicating code. We look at creating definition files to transform the actual JavaScript code to be compatible with TypeScript. By the end of the book, you will have ...
