Description

The third edition of Mastering Linux Security and Hardening is an updated, comprehensive introduction to implementing the latest Linux security measures, using the latest versions of Ubuntu and AlmaLinux. In this new edition, you will learn how to set up a practice lab, create user accounts with appropriate privilege levels, protect sensitive data with permissions settings and encryption, and configure a firewall with the newest firewall technologies. You’ll also explore how to use sudo to set up administrative accounts with only the privileges required to do a specific job, and you’ll get a peek at the new sudo features that have been added over the past couple of years. You’ll also see updated information on how to set up a local certificate authority for both Ubuntu and AlmaLinux, as well as how to automate system auditing. Other important skills that you’ll learn include how to automatically harden systems with OpenSCAP, audit systems with auditd, harden the Linux kernel configuration, protect your systems from malware, and perform vulnerability scans of your systems. As a bonus, you’ll see how to use Security Onion to set up an Intrusion Detection System. By the end of this new edition, you will confidently be able to set up a Linux server that will be secure and harder for malicious actors to compromise.

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

I really liked that many versions of Linux were covered here, I felt like nothing was left out. This is a great book to use to enhance your knowledge of security for Linux. There are great labs that lay out step by step what to do, and they are easy to follow along with. I particularly learned a lot on the logging chapter, which was very helpful to me and what I do for work. Overall this is very well written, easy to follow along, and has a ton of knowledge - I highly recommend it!

This book is great in that it covers ways and tips to secure Linux systems. It has a very practical approach with well written examples and great explanation for why/how. The tips that are scattered throughout the book are very informative.This is a great book to keep handy and refer it as we need to. I enjoyed reading through it.

It has been a while since I have classified a book as "interactive" and its not a lab workbook. I am truly impressed thus far which the labs that are present in the chapters!!! Anyone that gets this book will not be disappointed.
