preface states that this book is aimed at the network
and the security engineer, or the hobbyist, but it is
introductory work. The reader will need to know Linux
to the kernel
configuration level, and TCP/IP networking to the ARP
Resolution Protocol) level.
one addresses the basics of 802.11 security. Chapter
provides a background, and looks at issues, in wireless
communications, although primarily from a communications,
security, perspective. There is a review of attacks and
chapter two, and for once there is a comparison of wired
wireless hazards, ranging from the common (interference
phones) to the sophisticated (signal strength attacks
two deals with station, or remote device, security.
three examines attacks against machines and networks,
and suggests the
use of SSL (Secure Sockets Layer) and SSH (Secure SHell).
Configuration recommendations for the kernel, startup,
other aspects of FreeBSD are covered in chapter four.
six, and seven do the same for Linux, OpenBSD, and Mac
respectively (with a concentration on the AirPort utilities
Mac). Windows, in chapter eight, reviews basic workstation
only, with limited advice and direction.
three looks at access port security, and the setup
points under Linux, FreeBSD, and OpenBSD are all contained
security is the topic of part four, with chapter ten
at gateways and firewalls, while the use of the three
UNIX variants as
gateways is discussed in chapters eleven, twelve, and
Authentication and encryption, mostly with IPSec, is
chapter fourteen. A rather vague closing is given in
noted, this is not a book for beginners. Presumably
already know the most common dangers of wireless LANs,
allowing default access passwords to remain active, and
the station set identifier. WEP (Wired Equivalent Privacy)
dismissed as irrelevant: since it is deeply flawed, one
that the concentration on technologies such as IPSec
security is of greater use than suggesting minor improvements
use of WEP keys and initialization vectors. However,
it is a bit of a
pity that the authors took this route. With the addition
an extra fifty pages this could have been an excellent
