%T "Firewalls and Internet Security: Repelling the Wily Hacker,
As the first work to deal seriously and completely with the topic, the
first edition of "Firewalls and Internet Security" was one of those
classics that get known only by the last names of the authors, so as
not to leave any possibility of confusion with books whose titles may
When such a long time has elapsed between editions of a work such as
this, it is more than possible that the field has moved on far enough
that a minor updating of the material is simply not feasible. The
authors are quite well aware of the new territory: where useful, the
original structure has been retained, but otherwise, the book has
essentially been rewritten. A huge undertaking, but the only
practical course, in the circumstances.
Part one establishes a starting point. Chapter one, an introduction,
presents a number of basic, but worthwhile, security concepts. The
operations of various components of the TCP/IP protocol suite are
discussed, with the most serious security vulnerabilities helpfully
highlighted, in chapters two (lower layers) and three (upper layers).
The authors' thoughts on the security of the Web are amply expressed
in the title of chapter four: "The Web: Threat or Menace?"
Part two outlines the threats to networked machines. Chapter five
describes a number of different types of attacks. A variety of tools
for determining security weaknesses are listed in chapter six,
alongside discussions of the relative costs/benefits of disclosure
versus security by obscurity.
Part three details security tools and utilities. Chapter seven
reviews authentication concepts and techniques. Various network
security systems are described in chapter eight.
Part four gets us to firewalls and virtual private networks (VPNs)
themselves. Chapter nine outlines the different types of firewalls.
Basic filtering concepts are examined in chapter ten. Considerations
for constructing and tuning your firewall are in chapter eleven.
Tunnelling and VPNs are discussed in chapter twelve.
Part five extends the isolated technology of firewalls into the
application of protecting an organization. Network layout, and the
implications thereof, is reviewed in chapter thirteen. Chapter
fourteen deals with hardening of hosts. Chapter fifteen is a rather
terse look at intrusion detection.
Part six is entitled "Lessons Learned." The detection and tracing of
"berferd" is described in chapter sixteen, along with the taking of
the "CLARK" machine in chapter seventeen. In chapter eighteen,
Kerberos and IPSec are used as examples of approaches to security of
insecure networks. Chapter nineteen finishes with some ideas for work
that yet needs to be done to help with the security of the Internet.
The place of firewalls in regard to network security has broadened
considerably in the past decade. This book does reflect that reality.
Unfortunately, that breadth of topic has come at the expense of some
depth in coverage. The result is a book that is definitely worthwhile
as an introduction to the field, but which may no longer be suitable
as a working reference. I must admit that, for some time, I have been
recommending Chapman and Zwicky (cf. BKBUINFI.RVW) over Cheswick and
Bellovin's original text, since "Building Internet Firewalls" seems to
have the edge in terms of practicality. Upon reviewing this new
edition of the classic, I would have to stick to that recommendation.
