This book is an excellent resource for users and administrators of Linux to help secure and monitor their systems. A normal cookbook doesn't teach you everything there is to know about cooking- but rather provides recipes for those who know a little about how to cook to follow in order to get the desired end result. The Linux Security Cookbook works the same way. You must still have a working knowledge of Linux and how to configure and manage it. But, the Linux Security Cookbook provides a number of "recipes" you can follow to get the desired end result- a more secure system. It includes coverage of firewalls (iptables and ipchains), permissions and authorization controls, intrusion detection and more. Linux users should read this book.

For many home users the standard Ctrl-Alt-Del and entering a password may provide all the security they need. But, passwords can be guessed or broken and there ways around other forms of security. What SecurLock offers is an extra measure of security by requiring that the USB key be inserted as well. Requiring the physical device as well as a PIN number make it virtually impossible for someone unauthorized to log into your computer. SecurLock offers the ability to encrypt files using either Blowfish or RC4 encryption and can Shred files so that they can not be retrieved. You can also encrypt files to email to others and protect them with a password. If you need extra security the SecurLock system is definitely worth taking a look at.

The TICSA Training Guide is invaluable for anyone trying to prepare for the TruSecure ICSA Certified Security Associate certification exam (exam TU0-001). The information is explained clearly and the terms and resources in the appendix are very useful. The chapter questions and practice exam provide a good feel for the sort of questions you can expect to encounter on the exam. If you are studying for this exam, this book is a must-buy. If you are studying for a different security certification such as Security+ or CISSP, this book can still help you to reinforce the concepts you need to pass. If you aren't taking any exam, this book is still worth the time and money to help you learn and remember key security technology and concepts.

There are TONS of books out there on the subject of hacking- hacking tools, tricks, utilities and how to defend yourself against them. In fact, the creator of this CD video training course, Ed Skoudis, is the author of one of them- Counter Hack. The books contain great information, but some people don't learn as well just reading books. This course provides lessons on basic hacking techniques and network security to defend against them. Using talking-head video combined with slideshow presentations and video screen shots of the actual steps involved the course gives you a good overview of the subject matter. Tools are included for both Windows and Linux. Great to use in conjunction with a book like Counter Hack for hands-on experience.

Its a cruel irony in information security that many of the features that make using computers easier or more efficient and the tools used to protect and secure the network can also be used to exploit and compromise the same computers and networks. This is the case with packet sniffing.

What is port scanning? It is similar to a thief going through your neighborhood and checking every door and window on each house to see which ones are open and which ones are locked.

Another year has flown by. From a malicious code and security standpoint, 2005 continued to see a rise in phishing attacks as well as an evolution to more sophisticated phishing attacks. It was also a year where the malware underground and organized crime continued to join forces to write malware that was not only annoying, but written more professionally and with more financial impact on its victims.
