1. In Focus: Safer Mobile Surfing
I'm sure you read lots of different security-related blogs and Web
sites. There are a bunch of them out there, and the number seems to
keep right on growing. I've got dozens of them in my RSS reader, and I
often find new ones that I want to read now and then.
One interesting blog that I found some time ago is called Secureme. Not
only is it informative, but the writing style is subtly humorous at
times too. When I look at the "avatars" of the blog writers at the
site, I'm not quite sure what's missing: a flashy mirrored disco ball
and colored lights, or Santa's workshop. When you go to the blog,
you'll see what I mean.
An interesting recent post at the blog ("No SSH server, no problem!"
January 13) covered two tools, The Onion Router (TOR) and Privoxy, both
of which can be used in a variety of situations, such as using them
together to better protect your Internet communications when you're on
the road. For example, if you're using a hotel's in-house network or a
public wireless network, you could use TOR and Privoxy to help protect
your network traffic.
TOR is a routing technology that encrypts and routes your Internet
traffic through a number of TOR servers before the traffic reaches its
destination. Privoxy is a proxy server that helps protect your Internet
privacy by removing or obscuring various content, such as your DNS
queries, browser type, OS type, and more. You can configure Privoxy to
communicate with TOR so that all your Web traffic is routed through the
TOR network.
I tried the two tools, and they seem to work all right. Setting up a
TOR client is incredibly simple. Just install it, run it, and make sure
there are open ports on your firewall to pass traffic. That's it!
Privoxy is equally simple, except that to make it work with TOR, you'll
need to add one line to the Privoxy configuration, which is explained
in the TOR documentation. You can learn more about TOR and Privoxy and
download copies at their respective Web sites.

February the 13th: Microsoft Issues Massive Number of Security Fixes
Yesterday, Microsoft issued a massive number of security bulletins
and fixes as part of its regularly scheduled monthly security update
release. The company released 12 security bulletins for various
products, including several Windows versions, Exchange Server, Office
XP, Windows Media Player, MSN Messenger, and SharePoint. Eight of the
bulletins are rated as "critical," the company's most serious rating.
Microsoft to Purchase Sybari Software
Microsoft announced yesterday that it has signed a definitive
agreement to acquire Sybari Software, a New York-based company that
develops antivirus, antispam, and content-filtering technologies. The
acquisition will include all of Sybari's staff and technologies.
Weakness in Windows XP SP2 Overflow Protection
Security company Positive Technologies released a white paper that
explains what it considers to be weaknesses in the heap overflow
protection and data execution protection in Windows XP Service Pack 2
(SP2). The two technologies are designed to help prevent intruders from
taking advantage of unchecked buffers to launch malicious code within
the OS.
SOHO Firewall Appliances
Even if you have a home office or work for a small company, you
still need to protect your valuable data and network. Firewalls have
become a de facto standard for all organizations--large and small--as a
frontline perimeter-based defense against attackers who want to steal
your information, hijack your resources, and otherwise vandalize your
network. Jeff Fellinge looks at several solutions in this Buyer's
Guide.

Stop Users from Bypassing Group Policy
I read a really interesting thread on the Focus on Microsoft mailing
list. A list member said his users found a way to bypass Group Policy
so that they could install unauthorized software on their machines. The
users entered their logon credentials, then as soon as they were
authenticated to the domain, they unplugged the network cable so that
Group Policy Objects (GPOs) weren't downloaded to their machines.
However, there are ways to foil this strategy.
Two More Months to Opt Out of Windows XP SP2
According to Microsoft's TechNet Flash newsletter, "the mechanism to
temporarily disable delivery of Windows XP SP2 is available only for a
period of 240 days (8 months) from August 16, . At the end of this
period (after April 12, 2005), Windows XP SP2 will be delivered to all
Windows XP and Windows XP Service Pack 1 systems."

Security Forum Featured Thread: ISAPI Extension Access to DCOM
Application Server
Nicola has an Internet Server API (ISAPI) DLL that connects to a
Distributed COM (DCOM) application server. The setup includes a
Microsoft IIS server configured with integrated security and anonymous
access disabled, a domain group to collect all the domain users that
should be able to use the procedures in the DLL, and DCOM configured
with an administrator account and launch/access permissions for the
domain group. The setup works if the domain group is included in the
local Administrators group, but Nicola doesn't want to put the domain
group in the local Administrators group and wonders if there's some
other configuration that will work. Join the discussion at
