* NEW CERTIFICATION STANDARDS FOR FIREWALLS
ICSA Labs (see the URL below), a division of TruSecure, offers
firewall certification by testing firewalls against a defined set of
criteria. Firewall products that meet the criteria can claim ISCA Labs
Certification. In the past, ICSA Labs has used one set of criteria to
certify all firewall products, whether those firewalls were designed
for large corporations, small businesses, or residential users.
ICSA Labs has now developed "Modular Firewall Certification Criteria
4.0." The criteria include a base set of requirements--plus three
other sets of requirements that differ based on the firewall's target
market. According to ICSA Labs, "Version 4.0 is the culmination of
over a year and half of work with industry experts, end users and the
Firewall Product Developers Consortium - an international forum of
competing developers of firewall products that works toward common
goals to benefit both members and end users. Version 4.0 reflects the
different functional requirements in today's multi-segmented firewall
The base criteria module--applicable to all firewalls--requires that
firewalls adhere to specific logging requirements, provide certain
administrative capabilities, and maintain security policy persistence.
The firewalls must also pass functional tests to prove that their
policies and administration features work as intended, that they
prevent unauthorized access to administrative functions, that they
aren't vulnerable to evolving sets of attacks, and that they don't
introduce vulnerabilities through their integration into a network.
The firewalls must also pass tests that demonstrate their resistance
to trivial Denial of Service (DoS) attacks and their ability, if they
fail, to fail in a way that stops all network traffic to protect the
networks they guard. And, of course, the firewalls must also have
thorough, accurate documentation in such areas as installation,
administration, and maintenance.
The other three criteria sets (corporate, business, and residential)
have a few overlapping requirements, such as the default policy's
allowed inbound and outbound protocols and remote administration
capabilities. However, beyond those overlapping elements, the
requirements differ significantly according to target market. As you
might expect, the corporate firewall requirements are more stringent
than those for business firewalls, and those for business firewalls
more stringent that those for residential firewalls. The differences
among the three modules lie mostly in the areas of logging,
administration, and time/date persistence. Overall, the requirements
for any type of firewall are stricter than the previous requirements
ICSA Labs used. You can read about the exact criteria for each
firewall type at the URL below.
So far, the following companies and products have achieved ICSA Labs'
4.0 certification for corporate firewalls: Nortel Networks' Alteon
Switched Firewall, Novell's BorderManager, Check Point Software
Technologies' Check Point FireWall-1 Next Generation Linux FP-3, Cisco
Systems' PIX Firewall Family, CyberGuard Premium Firewall Appliance,
Global Technology Associates' (GTA's) GTA Firewall Family, Intoto's
iGateway, Fortinet's FortiGate-300, and NetScreen Technologies'
NetScreen Family. Other companies are in the process of certifying
their corporate firewalls under the new criteria.
To date, ICSA Labs hasn't certified any level 4.0 business products
and has certified only two level 4.0 residential products (both
hardware-based)--Jungo's OpenRG and RIAS's GreatSpeed GS-1540G. For a
list of all ICSA Labs certified firewalls, visit the URL below.
In general, the new multilevel certification criteria make sense.
Usually, a residential user's firewall doesn't need to meet the same
overall requirements as a firewall that protects a large corporate
network. For example, a residential firewall often doesn't need the
same remote administration capabilities that a business or corporate
firewall needs. ICSA Labs' new approach to certification should give
developers more flexibility by providing a way to certify products
that serve different target users.

2. ==== SECURITY RISKS ====
(contributed by Ken Pfeil, ken@xxxxxxxxxxxxx)
* DoS IN MICROSOFT OUTLOOK 2002
Richard Lawley discovered a Denial of Service (DoS) vulnerability
in Microsoft Outlook 2002. This vulnerability stems from a fault in
the way Outlook 2002 processes email header information. To crash a
vulnerable client, an attacker can send a message that contains
specific header information. The client will remain affected until you
delete the message from the server. Microsoft has released Security
Bulletin MS02-067 (E-mail Header Processing Flaw Could Cause Outlook
2002 to Fail) to address this vulnerability and recommends that
affected users apply the appropriate patch mentioned in the bulletin.
* CROSS-DOMAIN SECURITY VULNERABILITY IN MICROSOFT IE
GreyMagic Software and Thor Larholm discovered that a new Microsoft
Internet Explorer (IE) vulnerability can permit an attacker to perform
any action on the vulnerable computer that the user can perform. The
cause of this vulnerability is a flaw in the way IE handles
cross-domain security checks. Microsoft has released Security Bulletin
MS02-068 (Cumulative Patch for Internet Explorer) to address this
vulnerability and recommends that affected users immediately apply the
appropriate patch mentioned in the bulletin. This cumulative patch
also addresses all previously discovered vulnerabilities in IE.

* FAQ: HOW CAN I HIDE CORE ICONS FROM THE WINDOWS XP DESKTOP?
( contributed by John Savill, http://www.windows2000faq.com )
A. In earlier Windows versions, you could use a variety of registry
changes or Microsoft's Tweak UI utility to hide core icons such as My
Computer and Network Places from the desktop. With XP, Microsoft
provides an interface in the core product that lets you accomplish the
same task. To hide core icons from the desktop, perform the following
1. Start the Control Panel Display applet (go to Start, Control
