Yeah it usuallyl comes down to theory vs. implementation. Books on
theory usually have a longer life span, but don't tell you much about
how to protect your computer using the latest and greatest firewall
rules. Books on implementation will tell you how to protect yourself
using today's tools, but go out of style faster than the latest and
greatest reality show. In security I think that's kinda the nature of
the beast unfortunately. One outdated book I would recommend checking
out is "Securing and Optimizing Linux" which can be found here(legally I
hope):
http://www.mc.man.ac.uk/LDP/LDP/solrhe/Securing-Optimizing-Linux-RH-Edition-v1.3/
It's outdated, but I really liked it because a lot of the time it would
not only tell you what you should change to secure your system, but why
you should change it and what's at risk if you don't. There's also
complete pdf of the book floating around out there somewhere if you
don't mind searching.
I'm actually a student in the graduate security program at Davis so if
anyone has any questions about the program feel free to ask. I'm sure
there are many people on this list who know much more about linux
security and security in general than me, but I'd be happy to answer any
questions about the program itself. I think in general many people
would be suprised by how little practical security knowledge you
actually get in the graduate program here. Most of what your taught is
theory and any practical knowledge gained will be picked up in research
or projects of your own choosing. I'm really not sure if this is
typical of departments everywhere, but the longer I'm here, the more I
believe that we are the rule rather than the exception, atleast among
research institutions. -Adam
