%T "CISSP for Dummies"
A 'cheat sheet' is bound into the front of the book. It offers some
general advice for taking the CISSP (Certified Information Systems
Security Professional) exam, the most useful aspect of which is to
prepare. Most of the tips are vague, such as the suggestion to budget
your time, or review CISSP resources, without any information about
what factors should be considered in time management or where to find
resources. Some tips are overly specific, such as the recommendation
that you bring a big bottle of water. (Yes, six hours is a long time
for the exam, and, yes, you may need refreshment. The tip does not
mention that proctors vary in rigour when applying the exam
regulations, and may not allow bottles of water at the test tables.
Besides which, only one person may be excused from the room at any one
Part one reviews the CISSP exam itself. At the beginning of chapter
one, the authors point out that some CISSP study guides are too hard,
and some CISSP study guides are too soft, but this book is just right.
Then it moves on to information about (ISC)^2 (the International
Information Systems Security Certification Consortium), arrangements
for the exam, and some study tips. The material is more up-to-date
than in other CISSP study guides, but the text is badly written,
duplicating content and repeating itself, possibly because the
structure and organization is weak. The suggestions and information
are reasonable, although occasionally questionable: the
recommendations for study guides and practice exams are rather weak.
Chapter two briefly lists the ten domains of the common body of
knowledge (CBK), and is really only an expanded table of contents for
the chapters in the next section.
Part two describes the ten domains in detail. Chapter three covers
most of access control, but unevenly. Given the constraints that the
authors themselves mention (the CISSP CBK is a mile wide and an inch
deep), too much space is devoted to a simplistic set of password
choice rules, an excellent (but, in this situation, overlong) review
of Kerberos, and a number of jokes which are not going to help
candidates remember important points, and may very well confuse the
issues. Some material is problematic, such as the discussion of
security "domains" that follows the Microsoft networking model rather
than the Bell-LaPadula derived structure that the CBK requires, and a
baffling non-explanation of the lattice model. (There are also a
number of perplexing inclusions, such as a cross-reference to
cryptography in the introduction to single sign-on systems.)
Telecommunications and network security is presented in chapter four.
The authors have used the OSI (Open Systems Interconnection) model to
structure the discussion of various technologies: an interesting
concept, but one which is flawed by the fact that a number of topics
are placed in the wrong level. (Media access and packet switching,
for example, are listed in the data link layer, rather than the
physical and network layers, respectively.) There are also
problematic references to "native" PPP (Point-to-Point Protocol)
encryption, and an assertion that ICMP (Internet *Control* Message
Protocol) packets are not required for network operations. The basics
of security management are covered in chapter five, but very tersely.
The major standards are not listed here: the Common Criteria is
mentioned briefly in chapter eight (security architecture) but British
Standard 7799/ISO (International Standards Organization) 17799 is not
listed at all. The set of roles and responsibilities is short and
risk analysis terms are not well defined. This must be considered a
serious weakness in the book, since security management is very
important in the CISSP exam. Application development is dealt with
briefly and poorly: again, this is an area where many CISSP candidates
do need extra help, and they won't get it here. System development
methods are not discussed at all, and the malware section is full of
errors. (Each chapter lists a set of books for extra research: I
should note that neither of the virus books listed at the ISC2 site
appear on the list for this chapter. In fact, the bibliography is
rather short overall: Krutz and Vines "The CISSP Prep Guide" (cf.
BKCISPPG.RVW) which is not much better than the current work, is
listed in every set.) There are also odd inclusions from other
domains, such as almost a full page devoted to the SYN flood attack,
which was adequately explained in a paragraph in chapter four. The
material on cryptography, in chapter seven, lists all the terms and
technologies, but has poor or non-existent explanations, mathematical
errors, and the authors obviously do *not* understand S-boxes. (The
process described would not allow for decryption.) There is too much
text about CPUs (Central Processing Units), and too little on
distributed systems, formal models, and the various evaluation
criteria in chapter eight's review of security architecture.
Operations security, in chapter nine, seems to be a collection of
random topics, with a fair concentration on audit logs. Chapter ten's
overview of Business Continuity Planning (BCP) is not bad, although a
bit shy on details. (The vital topic of backups, for example, is
mentioned only long enough to say that you should have one, and the
various types, with varying strengths and weaknesses, are not
discussed at all.) Law, investigation, and ethics is reasonable,
although the list of specific privacy laws is probably not too helpful
(and I rather suspect that the authors got taken in by the "Desert
Storm Virus" myth). Most of the material on physical security, in
chapter twelve, appears to have been copied from some other source
without much understanding: the sections on visibility, capacitance
sensors, and UPSes (Uninterruptable Power Supplies) are among those
that contain errors or seem to miss the major points.
Part three is the usual "dummies" "part of tens." Chapter thirteen
relists the ten domains. (Didn't we do this already?) Ten other
security certifications are recorded in chapter fourteen. Websites
are given in chapter fifteen: three are actually useful. The cheat
sheet and chapter one are reprised in sixteen and seventeen. One of
the books listed in chapter eighteen ("Security Engineering," by Ross
Anderson, cf. BKSECENG.RVW) would be very useful for exam candidates.
Sample test questions are a big part of every CISSP study book (in the
case of Peltier and Howard's "The Total CISSP Exam Prep Book," in
fact, the *only* part). This book has both its own set of questions,
and a set from the Boson exams. As I have said elsewhere, the Boson
exams are not necessarily wrong, but they are far too simplistic to be
considered adequate preparation for the CISSP exam, and the answer
guides are completely tied to "Secured Computing" (cf. BKSCDCMP.RVW).
If any set of questions are simpler, and therefore less useful, than
the Boson set, they are the ones listed in this book. And, like the
Boson collection, the answers are completely self-referential.
Like Andress' "CISSP Exam Cram" (cf. BKCISPEC.RVW), this text does
sometimes simply list the terminology, although Miller and Gregory are
somewhat more complete and do provide greater explanations of the
domains themselves. It would be hard to make a distinction between
this volume and "Secured Computing": Miller and Gregory provide *some*
outside references but Endorf makes fewer errors. As previously
noted, Krutz and Vines do not give the reader much in the way of
explanatory material, but they do cover the domains more
comprehensively than the current work. Harris' "CISSP All-in-One
Certification Exam Guide" is, as noted (cf. BKCISPA1.RVW), the one
guide that might get you through the CISSP exam, albeit not
necessarily with high marks: Miller and Gregory might get you through,
but only if you stood a pretty good chance without the volume.
