Control access, change and availability of IT
   This paper provides an overview of the techniques for implementing 
internal controls and how these techniques are utilized to mitigate an 
organization's IT applications and infrastructure risk. This paper also 
discusses the importance of IT control standards and frameworks, such 
as COSO and CobiT, and examines specific examples of IT controls. Get

==== 1. In Focus: Auditing Your Systems Can Improve Security 
   by Mark Joseph Edwards, News Editor, mark at ntsecurity / net

As you hopefully know by now, Microsoft released nine security 
bulletins this month as part of its regular patch release schedule. One 
of the bulletins includes a vulnerability in Microsoft Distributed 
Transaction Coordinator (MSDTC). The vulnerability is serious, and an 
exploit has already been created. Although the exploit was created by 
Immunity Security strictly for release to its business customers, by 
the time you read this newsletter, someone else will likely have 
already released another exploit onto the Internet--possibly in the 
form of a worm or Trojan horse, either of which could lead to a 
complete compromise of your entire network. 

Protecting your systems in advance is of paramount concern. The obvious 
approach is to load the patch as soon as you can, and if you can't, for 
whatever reason, then take other defensive measures. MSDTC listens on 
TCP port 3372. Minimally, scan your network to determine which systems 
listen on TCP port 3372. You can disable MSDTC on individual systems or 
by using Group Policy. But doing so might break various types of 
functionality. Review Microsoft Security Bulletin MS05-051--
Vulnerabilities in MSDTC and COM+ Could Allow Remote Code Execution 
(902400) for details.
http://list.windowsitpro.com/t?ctl=16E62:4FB69 

The fact that someone created an exploit for the MSDTC vulnerability in 
fewer than 24 hours points out the need to stay on top of vulnerability 
reports and patching. It also points out the need to know precisely 
what software runs on your systems. A fantastic case in point is 
Mozilla Foundation, which I wrote about in a news story on our Web site 
that's also included in this newsletter. 
http://list.windowsitpro.com/t?ctl=16E67:4FB69 

In summary, the Spread Firefox Web site was compromised back in July. 
After that intrusion, Mozilla Foundation rebuilt the entire server. 
But, when doing so, the company failed to properly record what software 
runs on that server. Apparently between July and October, no 
significant audit was performed on the server either. As a result, 
Mozilla Foundation overlooked the fact that TWiki runs on the server, 
although not as a prominent service. (For more information about TWiki, 
go to http://list.windowsitpro.com/t?ctl=16E74:4FB69 ) 

You can probably guess what happened next: A vulnerability was 
discovered in TWiki, and soon an intruder began attempts to break into 
the Spread Firefox Web site. So Mozilla Foundation once again spent 
considerable time rebuilding a server that was rebuilt only a few 
months prior. The Spread Firefox site was taken offline by October 4, 
and didn't come back online until yesterday. I have no idea what the 
combined incidents cost the company in terms of time and money, but in 
addition to those costs, the incidents cost the organization in terms 
of reputation. 

These sorts of incidents can happen to anybody who doesn't know exactly 
what software runs on their systems and doesn't stay up to date on new 
vulnerabilities. The bottom line is that you're responsible to 
determine what software runs on your systems, and you can't rely on 
your software vendors to consistently provide you the latest 
vulnerability information. The reason for the latter is simple: When 
vulnerabilities are announced to the public (sometimes with only scant 
details), potential intruders can use that information to begin looking 
for a way to breach security. In some cases, all a discoverer needs to 
say is, "I found a problem in XYZ application," and someone else can 
use logic to figure out where the vulnerability might be, find it, and 
develop a way to exploit it. 

The lessons here are clear. In order to maintain optimum network 
security, you must audit your system regularly, keep precise and up-to-
date records, and monitor the Internet for new vulnerability 
developments. Doing so can make even the biggest networks a much 
smaller target.

Overlooked Security Patches Bring Down Spread Firefox Site
   Mozilla Foundation overlooked critical patches on its Spread Firefox 
site. As a result, the site was temporarily taken offline and site 
visitors were redirected to the Firefox area of the main Mozilla Web 
site.

VPN Firewalls Add Malware Protection
   NETGEAR announced the incorporation of Trend Micro's Client/Server 
(CS) and Client/Server/Messaging (CSM) Suite for Small and Medium 
Business (SMB) into the NETGEAR ProSafe VPN Firewall 200 (FVX538) and 
ProSafe VPN Firewall 50 (FVS338). Both firewalls now enforce security 
policies established by the network administrator by allowing Internet 
access for only those computers that have the latest antivirus and 
antispam signatures. Computers that aren't compliant will be redirected 
to a server to obtain updates. The ProSafe VPN firewalls with Trend 
Micro software are designed to be all-in-one security appliances for 
SMBs. They're list priced at $557 for the ProSafe 200 (200 simultaneous 
IPsec tunnels) and $278 for the ProSafe 50 (50 tunnels). For more
