==== 1. In Focus: Strengthen Browser Security with Third-Party Solutions
by Mark Joseph Edwards, News Editor, mark at ntsecurity / net
If you subscribe to our WinInfo email newsletter, then you've probably
read stories by Paul Thurrott that discuss how Microsoft will handle
improvements to Internet Explorer (IE) in the future. If you don't
subscribe to the newsletter and want to, then visit the home page below,
where you'll find a link to the subscription form.
As you know, it's been quite some time since Microsoft released a new
version of the browser. Meanwhile, other browsers, such as Opera
Software's Opera and Mozilla Firefox, have added considerable new
features and functionality. But Microsoft has decided that it will
introduce future IE improvements via service packs--it won't offer newer
versions of the Web browser as standalone software because the company
considers IE an integral part of the OS.
The recent Windows XP Service Pack 2 (SP2) offers improvements to the
underlying security of the OS and various components, including IE.
Microsoft isn't planning to offer similar improvements to Windows 2000
and earlier OSs.
Many of you can't upgrade to XP yet for a variety of reasons, but in the
meantime, you still want to improve overall system security. You can
gain some of XP SP2's improvements by using third-party products. In at
least one case--Windows Firewall--third-party products are typically
superior. Because Windows Firewall allows all outbound connections
without any means to control them, it's probably a wise idea to use a
third-party firewall on systems on which you require precise control
over network traffic.
To improve the IE security on Windows 2000 and previous OSs, three
options immediately come to mind, although there are probably others.
One option lets you keep using IE as your primary browser; the other two
options recommend that you use another browser as your primary browser
and use IE only when you have to for whatever reason. I describe the
options below in no particular order.
One option is to add PivX's Qwik-Fix Pro to your systems to help you
modify IE zones to lock down the browser and prevent malware from
exploiting the system. Another option is to purchase a browser such as
Winferno Software's Secure IE 2004, which is an IE replacement that
offers better security than IE versions prior to XP SP2's. The third
option is to use a free third-party browser such as Mozilla Firefox or
Opera Software's Opera, both of which offer functionality similar to
that found in IE under XP SP2.
Qwik-Fix Pro and Secure IE 2004 cost money, which of course is
reasonable to expect. Opera is available for free if you're willing to
view banner advertising while you use it; if you buy it, you can use it
ad-free. Firefox is open source and as such is available for free and
without banner advertising.

Recent Security Vulnerabilities

vulnerabilities. You can also find information about these
JPEG GDI+ Trojan Unleashed
It was only a matter of time before someone unleashed malware that
exploits the JPEG GDI+ vulnerability. Over the last two weeks,
various people have released proof-of-concept code. Now someone has
unleashed a JPEG file that causes a buffer overrun and runs shell
code on the affected system.
More JPEG GDI+ Exploits
As could probably be expected, intruders have begun using AOL Instant
Messenger (AIM) and other methods to exploit unsuspecting users who
have the JPEG GDI+ vulnerability. At least two new Trojan Horse
programs have been unleashed.
Welcome to the "You've Been Hacked" Blog
We've added a second security blog, "You've Been Hacked," hosted by
Brett Hill. Over the next few months, Hill will host a frank
discussion of security issues related to Microsoft OSs, services, and
products. As the blog title suggests, the blog will focus on what to
do if you think you've been hacked. We want to hear from you about
your experiences, questions, and concerns.

Check out this recent entry in the Security Matters blog:
Trojans with a Twist
Trojan horse programs are a bad enough problem because they can allow
remote access to a user's computer. One would think that having a
firewall in place would prevent a Trojan from opening back doors in
case of infection. But Windows Firewall won't prevent the
Win32.Surila.K Trojan from opening a back door on your system.

Security Forum Featured Thread: Disabling .vbs Files in an OU
A forum participant is looking for a way to use a policy to disable
the use of some .vbs files in an Active Directory (AD) organizational
unit (OU) while allowing the use of some .vbs files that he approves
of. His understanding is that he can implement only an "all or
nothing" policy and wonders whether anyone knows a way around this
limitation. Join the discussion at

Spam Solution Adds User Quarantine Features
Trend Micro announced new End User Quarantine (EUQ) features for
Trend Micro Spam Prevention Solution (SPS) to reduce Help-desk
burdens, to help corporate users manage their own "approved senders"
lists, and to improve accuracy and effectiveness. EUQ, a free add-on,
quarantines suspicious "graymail" messages (i.e., messages not
clearly identifiable as spam) into Microsoft Exchange Server folders
for each user. Thus, SPS users have instant access to potentially
important messages and can individually approve any problematic
senders. EUQ improves SPS's reporting and management capabilities and
decreases the number of false positives while increasing the spam
