by Michael D Bauer


Michael D. (Mick) Bauer, CISSP, is Network Security Architect for a large financial services provider.

Michael D. Mick's areas of expertise include Linux security and general Unix security, network (TCP/IP) security, security assessment, and the development of security policies and awareness programs.

Author Michael D. Bauer, a security consultant, network architect, and lead author of the popular Paranoid Penguin column in the Linux Journal, carefully outlines the security risks, defines precautions that can minimize those risks, and offers recipes for robust security. He is joined on several chapters by administrator and developer Bill Lubanovic

Linux consistently appears high up in the list of popular Internet servers, whether it's for the Web, anonymous FTP, or general services such as DNS and delivering mail. But security is the foremost concern of anyone providing such a service.

But we still need to pay for servers and staff

We’re dedicated to reader privacy so we never track you. We never accept ads. But we still need to pay for servers and staff. I know we could charge money, but then we couldn’t achieve our mission: a free online library for everyone.

Michael D Bauer addresses this problem in Linux Server Security (O’Reilly), aconcise, and yet somehow extensive, guide to configuring your Linux server for security. Knowing how to correctly configure each of these units for security, rather thanstraightforward operation, can be difficult at worst and time consuming at best.

This text should help you master the principles of reliable system and network security by combining practical advice with a firm knowledge of the tech nical tools needed to ensure security. The book focuses on the most common use of Linux - as a hub offering services to an organization or the larger Internet-and shows readers how to harden their hosts against attacks.

This highly regarded book, originally titled "Building Secure Servers with Linux, combines practical advice with a firm knowledge of the technical tools needed to ensure security. The book focuses on the most common use of Linux--as a hub offering services to an organization or the Internet--and shows readers how to harden their hosts against attacks. An all-inclusive resource for Linux users who wish to harden their systems, "Linux Server Security covers general security such as intrusion detection and firewalling a hub, as well as key services such as DNS, the Apache Web server, mail, and secure shell.

Author Michael D. Bauer, a security consultant, network architect, and lead author of the popular Paranoid Penguin column in the "Linux Journal, carefully outlines the security risks, defines precautions that can minimize those risks, and offers recipes for robust security. He is joined on several chapters by administrator and developer Bill Lubanovic.

A number of new security topics have been added for this edition, including:

Database security, with a focus on MySQL

Using OpenLDAP for authentication

An introduction to email encryption

The Cyrus IMAP service, a popular mail delivery agent

The vsftpd FTP server

Geared toward Linux users with little security expertise, the author explainssecurity concepts and techniques in clear language, beginning with the fundamentals. "Linux Server Security with Linux provides a unique balance of "big picture" principles that transcend specific software packages and version numbers, and very clear procedures on securing some of those software packages on several popular distributions. With this book in hand, you'll have both the expertise and the tools to comprehensively secure your Linux system.

I read every column of paranoid penguin and they are quite good. This book is ok, but not great. They (I mean they because several chapters are not by Mike) try to cover a huge amount of information and make the mistake of being both too broad in some areas and too specific in others. Overall, there wasn't a cohesive glue to bring the chapters together into a single vision.

For instance, for a book that introduces FTP servers, web servers, mail (imap/smtp), dns - they are like separate entities. They do not complete the picture by showing a complete network diagram with IDS / VPN, -- showing an example of all of their advice coming together in a working solution. And Kerberos isn't even mentioned.

They were extremely specific in some areas like talking about rpm example/debian/ make options and specific .conf options ad nauseum - which detracted from the whole picture. Is someone securing bind 4 really reading this book? Also, maybe a mention of apt-get - - but don't tell me how to install each package on every architecture - it just inflates the word count.

I don't think this book was focused enough in the 'big picture' of trying to piece together all of the tiny pieces into a coherant whole, while at the same time it gets cought up in the minute details of certain packages making for a tough read.

Perhaps they could have included an actual example company or two showing possible layouts of ldap in action with:

login/mail/split-dns/firewalls/database$web.

Anyone for OpenBSD?

Great book for school!

I know I'll be rated down, as everything I write here gets rated down.

First off is the reason I got a copy of this book. (thank god it was used) I am experimenting with options to lock down linux, I wanted to know about, and set up a wide range of technologies to get a good feeling for how much security linux can provide.

I was quite happy to see a section covering how to be a small time CA. (found at the beginning of the stunnel section) This section is so bad, it doesn't even use the right options to say sign a cert from a different server. That is right a book I paid money for didn't even bother to look up the correct options to sign a cert, to be a small time CA? The kerberos section was ok, but it reads like a hobbyist wrote the chapter, and not an experienced admin. I found myself taking notes to follow along, just to redo the instructions to fit my own needs. Lastly ldap. This chapter is simply so awful it inspired me to write this review. I was testing the chapters of this book against the current Debian stable. The only thing this book is good for, is to let you know what other books you should buy instead. I just placed orders for dedicated books, on the chapters from this book I was interested in learning more about.

To recap: The instructions are wrong, the book is inconsistent. I am ashamed o'reilly let this book pass as they have some of the best books.

It used to be that Linux was so much safer than Windows because of the sheer number of people out attacking Windows. But now there several reasons for the bad guys to attack Linux:

73 (or so) of the web servers run Linux,

more than that run DNS or mail,

these tend to be powerful boxes with big communications pipes - just what the Spammers need.

As the book says it's futile to expect perfect security unless you turn off the machine, power it down, repeatedly degause its hard drive and pulverize the whole thing into dust. On the other hand, it's not too difficult to do at least a minimal amount of hardening that will dramatically increase the effort required to break into the system.

This book, written by the author of the popular Paranoid Penguin column in Linux Journal covers the general rules. It gives you a broad coverage of the types of attacks you can expect and how to counter them. It does not attempt to cover the problem of the moment, because these are changing so fast that the book would be immediately out of date.

System security is a constant struggle against the dark side of the force. If you haven't been hit yet, you will be.

The book plays to linux's strengths on server side computing. Where the server controls a subnet of computers that depend on it to connect them to the Internet, or for other resources. Bauer emphasises throughout how to secure the server. Starting with a top down risk analysis and a designing of a perimeter network; typically a DMZ. So he carefully suggests what belongs in the DMZ and what belongs behind it.

He deprecates cleartext network communication, in favour of ssh and SSL for remote access. The book has concise explanations of various intrusion detection systems like Nesses and Vlad. Though perhaps if you do decide on using Nessus, you may also want to consult books devoted to it.

Overall, the book is a sobering and cautionary tale of current computing. With the best practices recommended here, you can remain reasonably secure.
