Abstract: Many useful guidelines for improving the security
of your unix system. UNIX system security can be divided into
three main areas of concern. Two of these areas, account security
and network security, are primarily concerned with keeping
unauthorized users from gaining access to the system.  The third
area, file system security, is concerned with preventing
unauthorized access, either by legitimate users or crackers, to
the data stored in the system.  This paper describes the UNIX
security tools provided to make each of these areas as secure as
possible.
