Linux: A Better Option for User
As I am sure everyone is already aware, the much publicized
Microsoft security initiative has taken some discouraging
hits as of late. MyDoom, Nimda, MS Blast and other significant
Microsoft exploits caused users millions of dollars in damages
and shows that Microsoft's security plan still has a long
way to go. As these incidents continue to impact Microsoft
customers, the case for Linux as a more secure business solution
continues to strengthen.
Even after the
Trustworthy Computing initiative was announced by Microsoft
more than a year ago to improve focus on security, Gartner
Research advised its Microsoft customers that the Windows
server platform is not ready for mission-critical applications
due to significant security concerns. It is through this initiative
that Microsoft executives made very strong statements committing
all their efforts toward security, yet their users continue
to fall victim to debilitating security flaws. Throughout
2003, the first year of this program, Microsoft had released
an average of nearly one security patch every week for the
duration of the year. What exactly is this initiative supposed
on the recent leak of Microsoft's intellectual property concur
that their convoluted security management systems and "bolted
on" approach to improving security does nothing more
then leave users confused and provide only questionable levels
of protection. This complex combination of piecemeal security
features and the effects of having only a limited staff with
sufficient access to the source code makes it nearly impossible
to discover and eradicate all potential vulnerabilities, leaving
many remaining for exploitation. Due to their need to prioritize
which vulnerabilities will be patched, customers subsequently
only receive the updates Microsoft deems worthwhile.
The open source
approach, however, affords users a substantial number of resources
from developers in the community to ensure that even seemingly
insignificant security flaws are properly fixed. The unfailing
group effort and dedication of the open source community continuously
results in vulnerabilities being identified and patches being
released more rapidly, mitigating potential security risks
before negatively affecting the end user.
Due to the consistent
occurrence of security issues circling Microsoft, Linux has
made its way into the mainstream and is becoming more widely
accepted every day. Providing customers with a reliable, scalable
platform, Linux offers a solid budget friendly alternative
to those offered by proprietary vendors without sacrificing
functionality and power.

My inbox gets inundated with spam and it takes me forever
to manage. Can you help me get rid of it?
A. Although a combination of many different
features is what makes an anti-spam product effective, the
best way to eliminate spam from your inbox is through filtering.
Most email clients will allow you to set up spam filters by
creating rules. These rules are usually based on developing
spammer patterns or through the use of blacklists, whitelists,
trusted senders lists, etc. However, continually creating
and updating these rules becomes a tedious and overbearing
solutions, like Guardian Digital's Secure Mail Suite, are
designed to solve this problem by incorporating the most technologically
advanced anti-spam features with little required end-user
administration. In addition to basic filtering techniques,
more advanced spam fighting methods should also be incorporated.
These methods include heuristics systems to learn patterns
of spammers, envelope and content analysis, file attachment
management and next-generation Bayesian filtering which statistically
analyzes whether an incoming message is spam and continuously
learns the techniques of spammers so your inbox is always
anti-spam solution to truly be effective, it should integrate
all of these features and release frequent updates to consistently
thwart the ever-changing techniques of spammers.
