Linux Advisory Watch is a comprehensive newsletter that outlines the
security vulnerabilitiaes that have been announced throughout the week.
It includes pointers to updated packages and descriptions of each
vulnerability.
This week, advisories were released for openslp, zip, netris, autorespond,
unzip, eroaster, and GDM. The distributors include Conectiva, Debian,
Mandrake, and Red Hat.
The United States National Institute of Standards and Technology recently
released the second draft of the "Guide for the Security Certification and
Accreditation of Federal Information System." It is currently in the
second public comment period, which ends August 31st 2003. Although the
document is intended for government agency use, it is easily applicable to
organizations of other types. As information security is becoming a more
important function of conducting business, there is an ever increasing
need for standards and methodologies. This document is an excellent
starting point for those interested in creating an organization wide
information security program and/or certification and accreditation
procedures.
The document begins with an introduction to the concept of certification
and accreditation. It includes the system development life cycle,
component evaluation, assessment activities, as well as other important
information. Next, the document overviews the fundamentals of C&A
including roles and responsibilities, information system categories,
documentation, and monitoring. Overall, the first two chapters of this
document provide a very overview of the base knowledge required to setup a
certification and accreditation program in your organization.
The final chapter of this document walks readers through the entire
process of C&A. It covers initiation, certification, accreditation, and
finally monitoring. This chapter gives readers a very good indication of
the work required to implement and C&A program. In addition, after
reading this chapter the importance of beginning the C&A process becomes
apparent.
In addition to clear and informative writing, the document also provides
many easy to read diagrams. The illustrations provided help readers more
easily visualize the authors intentions. If you haven't had a chance to
take a look at this document, I highly recommend it. The information is
valuable and freely available. The entire document can be found at the

they have only recently gained the notoriety they deserve.

REVIEW: Linux Security Cookbook
There are rarely straightforward solutions to real world issues,
especially in the field of security. The Linux Security Cookbook is an
essential tool to help solve those real world problems. By covering
situations that apply to everyone from the seasoned Systems Administrator
to the security curious home user, the Linux Security Cookbook
distinguishes itself as an indispensible reference for security oriented
individuals.
