Review: The Book of Postfix: State-of-the-Art Message Transport

I was very impressed with "The Book of Postfix" by authors Ralf
Hildebrandt and Pattrick Koetter and feel that it is an incredible
Postfix reference. It gives a great overall view of the operation
and management of Postfix in an extremely systematic and practical
format. It flows in a logical manner, is easy to follow and the
authors did a great job of explaining topics with attention paid
to real world applications and how to avoid many of the associated
pitfalls. I am happy to have this reference in my collection.



Introduction: Buffer Overflow Vulnerabilities

Buffer overflows are a leading type of security vulnerability. This
paper explains what a buffer overflow is, how it can be exploited,
and what countermeasures can be taken to prevent the use of buffer
overflow vulnerabilities.



Getting to Know Linux Security: File Permissions

Welcome to the first tutorial in the 'Getting to Know Linux Security'
series.  The topic explored is Linux file permissions.  It offers an
easy to follow explanation of how to read permissions, and how to set
them using chmod.  This guide is intended for users new to Linux
security, therefore very simple.



>> The Perfect Productivity Tools <<

WebMail, Groupware and LDAP Integration provide organizations with
the ability to securely access corporate email from any computer,
collaborate with co-workers and set-up comprehensive addressbooks to
consistently keep employees organized and connected.

Dr. Walter, Head of Cryptography for Comodo Inc. and chair of the
Trusted Computing Group (TCG) Peripheral Working Group, has clarified
the relationship between encryption and authentication. The blurred

two groups. Authorities such as Comodo and VeriSign compete head to
head, to deliver high assurance digital certificates whilst other
groups concentrate on the low assurance


* Sentry CD - A different firewall approach
  30th, May, 2005

If you want to set up a Linux-based firewall, there's no need to run
a bloated distribution that installs everything but the kitchen sink.
If you are not afraid to get your hands dirty, and like having total
control over your system, then Sentry Firewall CD (SFCD) is just what
you need. It is a highly configurable, bootable CD that takes a
minimalist approach to firewalling.


* Many unaware of browser-security link

* Network Security to Take Top Spot

* Zombie machines used in 'brutal' SSH attacks
  2nd, June, 2005

It's a tedious activity that can put the best of IT administrators to
sleep. But as security and compliance manager for a large U.S.

* An Introduction to Securing Linux with Apache, ProFTPd and Samba

may be using Linux because they want to try something new, are
interested in the technology, or simply cannot afford or do not want
to use Microsoft Windows.


* Review: FreeBSD 5.4
  1st, June, 2005

One of the oldest Unix-like operating systems, FreeBSD, continues its
advancement with the sixth release in the FreeBSD-5 series. Its

* Employee Training & Education Can Mitigate Threats
  31st, May, 2005

Many Internet threats are easily avoidable and just executed by
employees who are simply unaware of their presence. Once briefed on
basic Internet security, it is equally important to keep your
employees educated as well. When new threats arise, send out memos
alerting each employee of the threat, how to identify it, and what to
do if and when they have it,. says security expert and Guardian
Digital CEO Dave Wreski.


* Security Action Plans
  1st, June, 2005

Centralization, automation, problem prioritization--many IT-security
professionals are embracing those concepts as they fight off the
never-ending onslaught of threats. Security products can help
businesses stem the flood of vulnerabilities, but IT teams also have
to put in place processes to ensure that they're responding
appropriately and being proactive in warding off potential dangers.
Fact is, some companies spend too much on some parts of their
organization and not enough on more-vulnerable areas.

The Fedora Project, a Red Hat-sponsored and community-supported, open

Directory Server freely available to the open source development
community, Red Hat is enabling and encouraging the development of
secure, enterprise technologies and providing customers and partners
with increased choice. The availability of Fedora Directory Server
licensed under the GPL underscores Red Hat's true commitment to open
source innovation.


* How to crack passwords, and why you should
  2nd, June, 2005

Auditing passwords is a worthwhile venture, particularly in an
environment that deals with sensitive information. Because systems
encrypt passwords when they store them, you really can't properly
judge the strength of a password unless you try to crack it.
