IT Security Cookbook This book is online and is basically about Security methodologies. I just read some chapters out of it. It's kind of okay and really going deep.

How to run successfull Projects ... A nice introduction to project management. It's really written the American way. There is one and only one theory about how to manage projects correctly. If you read the book with some distance and do not take everything for absolute, I would absolutely recommend it. It has a couple of forms and lists which are really helpful in managing your own projects, so you can be sure that you did not omit anything on the way to your projects goal.

Sendmail I started to read this book. It's a project for itself to finish it. It gives you a nice overview on all the things you might want to configure in your sendmail.cf file. But reading it from page 1 to the end might not be feasible. Use it as a reference in really hard times and you will find the answer!

Building Internet Firewalls Wanna know about Firewalls, Proxies, Socks, ... read it! This book is also called the Firewall Bible. If you need to know which packets you should block from entering your network or what ICMP to allow, you will find the answer in here. It also tells you about the possible topologies around a firewall and what a firewall really is.

Learning the VI Editor A really great introduction and reference to the VI editor. A couple of clones are also discussed here. I always thought I really new VI. But I was wrong! I found a lot of very interesting things in here which I did not know before!

Network Troubleshooting Tools Another great book out of O'reilly's kitchen. A must for every system administrator. A lot of tools are described in the book. The nice thing is that they are described in a manner which you will use them in your normal networking day.

TCP/IP Illustrated Volume I

The definitive Guide to SSH

Secrets & Lies

Learning Perl

DNS and BIND If you are using BIND on your machine to handle DNS, you probably wanna have a look into this book. At first, the DNS mechanism itself is described. Then tools like dig and nslookup are discussed. And in the main part you will learn how to write correct bind configuration files. (Don't be a fool and think this would be easy. I know what I am talking about! Or do you know what all those error messages in the syslog mean?! The book will tell you!)

Hack I.T.

Incident Response - Investigating Computer Crime

Hacker's Challange

CISSP Prep. Guide The book presents a short and compact overview of the ten domains for the CISSP exam. What really stroke me is Chapter 3 which talks about "Telecommunications and Network Security". It has quite some unprecise and at some points even wrong statements which confuse the reader unnecessarily. There is better material out there which covers these things much nicer (e.g. Building Internet Firewalls, Zwicky). Good to get an overview, but don't solely rely on this book to back you for the exam!
