Yes there is: 

Unix System Security
by Patrick H. Wood and Stephen G. Kochan

(From the back)

Here is a practical guide to computer security on the Unix system for the
user, administrator, or potenial Unix buyer.  It will teach you 
everything you need to know to make your system secure and keep it
that way.  Topics covered include:

* file and directory permissions

* password security

* how the setuid/gid permissions work and how to use them

* How the various security-related Unix commands and functions work

* how to write secure programs

* different methods of data encryption - including the government
  standard DES algorithm -- and how secure they are

* data encryption over communication networks

* how to discover and plug potenial security holes in your system

* how to periodically monitor your system to maintain security

Also included is the complete surce for several security auditing and 
administration programs.

If you are a novice this will give you a cookbook guide to security and
if you are a wizard it will be a good spring board for better programs
to improve your security.  In my security seminar I aways recommend that
they get a copy.  It the best investment in security that you can make.
