I wrote this book originally because no Linux security documentation existed back in the late 1990's. Since then several Linux security books have been published, but in general they all have shortcomings (for example one of them spends 40 pages on cops, a largely obsolete tool). So anyways I've decided it's time to update the book, which is one major advantage of doing this on the www. Currently it is April 2001, I'm hoping the major rewrite will be done by fall or winter of 2001 and then the LASG can go back into "maintenance" mode for a while. Writing the preface is boring so I'm gonna stop here and you can go read the book itself.
I'd like to thank my family for being supportive and putting up with me.
There is an announcement mailing list at: http://lists.seifried.org/mailman/listinfo/lasg-announce/. Semi-regular postings are made to announce new updates, sections and any major changes.
There is a discussion list for the LASG available at: http://lists.seifried.org/mailman/listinfo/lasg-discuss/. Appropriate topics incluse feature requests, errors, expanding on content, linux security, etc.
You can contact the author directly at: [email protected].
Since this is rapidly approaching "real book status" I decided it was time to format it nicely.
Only one chapter title per chapter (individual files), linked from TOC.
Multiple section titles per chapter, linked from TOC

The beauty of this book is that it is available online, thus bugs and errata are done in real time. What you read is generally the most up to date version. If you find a problem please tell me, [email protected].
This book refers to dates and times in numerous places. Unfortunately there are no universally used conventions for simple things like writing dates, which is rather annoying. I have decided to use "international" standards as opposed to American/Canadian standards, while this may cause some confusion it makes sense to me.
Dates will be written using the ISO standard of Day first, then the month, and finally the year. For example the date August 21, 2001 would be written:
21/8/2001
Long dates will be written the day first, then the month, then the date and finally the year. For example the date August 21, 2001 would be written:
Tuesday, August 21, 2001
Time references are in GMT unless otherwise noted. References to duration are in the form hours, minutes and seconds (HH:MM:SS). A time of one hour, twenty minutes and thirty seconds would be written:
1:20:30
