11/6/03 12:30 PM - Windows Networking/Security - TechNet Webcast: Securing

Wireless Security Solutions - Level 300

 

http://msevents.microsoft.com/cui/eventdetail.aspx?culture=en-US&eventid=1032237963

 

Wireless networks are an ideal option for keeping employees connected and

freeing them from their dependence on LAN (local area network) connections.

Analysts anticipate marked gains in productivity from wireless adoption; and

wireless networks help organizations minimize the use of costly switches and

cabling. However, the same capabilities that make wireless so attractive can

also open up vulnerabilities to malicious access. ( more description at

webcast link)

 

11/7/03 11:30 AM - Windows Server - TechNet Webcast: Introduction to Windows

Server 2003 - Level 200

 

http://msevents.microsoft.com/cui/eventdetail.aspx?culture=en-US&eventid=1032237092

 

This session introduces the new features of Microsoft® Windows ServerT 2003

and shows how they can be used to streamline administration, speed

deployment, and resolve issues with past Windows network deployments. The

broad range of topics includes Active Directory®, IIS 6.0, and scalability.

 

11/12/03 8:00 AM - Security - TechNet Webcast: Microsoft Security

Resources - Level 200

http://msevents.microsoft.com/cui/eventdetail.aspx?culture=en-US&eventid=1032237093

 

Today enterprises face the challenge of getting their systems secure and

keeping them secure. The technologies and processes required to protect

business data while minimizing system downtime are difficult to implement

and configure. Time spent dealing with security issues and viruses leads to

downtime and lost productivity. In this session we will discuss and

demonstrate a number of security resources, tools and services offered by

Microsoft for the enterprise environment such as the Microsoft Baseline

Security Analyzer, the IIS Lockdown Tool, the security guides for Windows

2000, Windows XP, and Windows Server 2003, as well as discuss some guidance

on how to manage patches in your environment.

 

11/13/03 9:30 AM - Windows Server/Networking - TechNet Webcast: Building a

Internet Service Provider (ISP) using IIS 6.0 - Part I - Level 200

 

http://msevents.microsoft.com/CUI/EventDetail.aspx?EventID=1032237095&Culture=en-US

 

The first of a two part series designed to help intranet and internet

administrators of IIS 6.0 understand how to securely build a internet

service provider solution using IIS 6.0.  This first part will focus on the

IIS configuration that allows for complete user isolation (content and

process model) .  This will also advise how to build complete backup

solutions in case of disaster recovery.

 

11/13/03 11:30 AM - Windows Server/Security - Microsoft Executive Circle

Webcast: Advanced Web Server Security with IIS 6.0 and Windows Server 2003

 

http://msevents.microsoft.com/CUI/EventDetail.aspx?EventID=1032238039&Culture=en-US

 

IIS 6.0 provides vastly improved security for Web servers. IIS 6.0 is locked

down by default, limiting the attack surface through aggressive security

defaults. Web Service Extensions, which prohibits any executable from

running unless it is specifically allowed, makes it very difficult for an

attacker to launch malicious applications on the server. In addition, there

are many important security related improvements including rigorous html

parsing standards, new server logs and status codes to facilitate

troubleshooting web applications, and the ability to change worker process

identity from the user interface.  These IIS improvements coupled with

security improvements in the Windows 2003 Server Family allow you to

securely deploy your web servers and keep them secure while decreasing

system management costs. Join in this webcast to hear why customers have

switched from Linux and Apache to Windows Server 2003 and IIS 6.0, and from

IIS 4.0 and IIS 5.0 to IIS 6.0, for the security and additional benefits IIS

6.0 offers.

 

11/13/03 8:00 PM - Windows Server - TechNet Webcast: Automating

11/18/03 1:00 PM - Windows Networking - Secure Your Networks: Wireless Set

Up and Security

 

http://www.microsoft.com/usa/webcasts/upcoming/2431.asp

 

There's no question that wireless technologies provide flexibility for

organizations to provide mobility to users throughout the enterprise,

however, many ponder the following question: Are wireless technologies as

insecure as you've heard them to be? Hear from wireless technology experts

about how organizations around the world have used a combination of

encrypted wireless technologies, network tunneling, and new technologies

(802.1x, certificate-based encryption, NAT-T, etc.) together with Microsoft®

Windows ServerT 2003 to leverage security best practices for creating

end-to-end secured wireless communications. (These can also be easily added

as member server systems into existing Microsoft Windows NT® 4.0 and

Microsoft Windows® 2000 networks.) All attendees to the session will receive

a "top 10" list on how to lock down security holes in wireless networks, and

then use publicly available test tools to validate secured communications.

Revamping the Security Bulletin Release Process
Community Bulletin
Revamping the Security Bulletin Release Process  *  October 15, 2003

In response to extensive customer feedback, Microsoft is implementing
changes in the way security bulletins are released. A detailed white paper
about the changes that are being implemented can be found at
http://www.microsoft.com/technet/security/bulletin/revsbwp.asp.

Security bulletins will normally be released on the second calendar Tuesday
of every month. However, the first monthly bulletins will be released on
Wednesday, October 15, 2003.

As before, Microsoft will issue a single security bulletin per patch. An
additional security bulletin summary document per product family will be
issued that will provide summarized information for all the patches released
that month for the product family. Microsoft will also provide additional
prescriptive guidance within the security bulletins including workarounds
for all vulnerabilities where a workaround is feasible, risk-assessment for
specific threats, and other information that will make it easier for
customers to evaluate and deploy the patches. A Knowledge Base article for
every patch will be created that will provide a link to the corresponding
security bulletin without duplicating the same information.

The new security bulletin format and process applies to both the technical
bulletin (targeted at IT Pros and other technical users) and the consumer
bulletin (targeted at the non-technical users). The primary differences are
in the level of technical details and that the consumer bulletin will be
limited to Windows and Office patches.

Microsoft currently provides customers with a number of tools and resources
to help manage the complex task of patch management and deployment.  These
tools and resources are located at
http://www.microsoft.com/technet/security. Microsoft also provides clear
product lifecycle policies (http://www.microsoft.com/lifecycle) so customers
are able to plan on the availability of security patches for supported
software products.

Customers using Microsoft's patch management and deployment tools such as
SMS (Systems Management Server) with Feature Pack 3, SUS (Software Update
Services), MBSA (Microsoft Baseline Security Analyzer), Windows Update and
Office Update will not need to upgrade or replace their tools to continue
using them.

Customers using non-Microsoft patch management and deployment products will
need to work with their vendors to ensure that their products continue to
function with the new process.

Product Support Services - Updated Information Regarding Microsoft Security Bulletin MS03-039

The PSS Security team is issuing this alert to advise customers that exploit code and a tool related to the vulnerabilities patched by Microsoft Security Bulletin MS03-039 is now publicly available.  To date, we have no seen widespread use of this code in the wild, nor have we seen any virus or worm using this exploit.  Exploit code currently available will provide a remote shell to an unpatched system.  If the system has been patched with Microsoft Security Bulletin MS03-039, the system will not be compromised but may experience a Denial of Service. The Microsoft Security Response Center is actively investigating the issue of the Denial of Service.

 

Customers who have not deployed the patch or taken additional mitigating actions to protect their environment, such as those described in Microsoft Security Bulletin MS03-039, should be aware that the existence of exploit code makes it easier for attackers to leverage the vulnerability to tamper with a customers unpatched systems. It also makes it easier for an active virus or worm to be developed.  We are therefore strongly urging customers to immediately deploy the patch in their environments and take additional mitigation steps, as described in the bulletin, to protect their systems.

 

Information on Microsoft Security Bulletin MS03-039 and its associated patch, mitigating factors and workarounds can be found here:

 

http://www.microsoft.com/technet/security/bulletin/ms03-039.asp

 

PSS Security Team

 

If you have any questions regarding this alert please contact your Microsoft representative or 1-866-727-2338 (1-866-PCSafety) within the US, outside of the US please contact your local Microsoft Subsidiary.

How Microsoft Does IT

Often times people ask or want to know how we do stuff here at Microsoft, especially in the security area. For the answer to that and many others, see:

http://www.microsoft.com/technet/treeview/default.asp?url=/technet/itsolutions/msit/default.asp

Security Bulletin Resources

I think that some of these are pretty cool:

http://www.patchdayreview.com
A site by MVP Robert McLaws that tries to describe our security bulletins in simple english. He uses this same .Text weblog app as well so you can get his RSS feed.

http://www.shavlik.com/bulletin_search.aspx
Shavlik's bulletin search. They have tied their on line app to the mssecure.xml file. I've always wanted to build that same app but never had the time. I even picked up a domain name I thought I would host it on: mshotfix.com. Anyone interested in a project? ;-)

http://www.opensec.org/feeds/
The Open Security Project. This site has RSS feeds for MSFT bulletins, Red Hat bulletins and CVE XML upates.

http://www.microsoft.com/technet/security/current.asp
This is of course the authoritative source for Microsoft security bulletins

New RPC/DCOM Exploit?

Microsoft is aware of the reports about a possible new exploit. These reports indicate that a machine up to date with all the latest patches may be vulnerable to either DoS or compromise. If our investigation shows that there is a true vulnerability, we will release a new patch.

Meanwhile, we recommend that all users protect their systems with a firewall. Please visit http://www.microsoft.com/protect and follow the simple instructions there.

Changes to the patching experience

In Steve Ballmer's announcement on Thursday, he indicated the following changes to our patch management experience:

  • Extended support for Win2k SP2 and NT 4.0 SP6a until June of 2004
  • We will reduce the number of installers used to two (one for the OS and one for apps)
  • Improve patch quality through increased testing and enabling rollback
  • Reduce the size of patches using Delta patching technology
  • Reducing patch related reboots
  • Improve the consistency of tools (MBSA, SUS, SMS)
  • Windows Update will become Microsoft Update - one place for all patches
  • Monthly patch release schedule - instead of every week, patches will go out on a monthly schedule unless there is an emergency patch

Time frame for all these changes - inside of 18 months

New Prescriptive Guidance Page for IT Pros

This is the one stop place for IT Pros to go to get Microsoft’s prescriptive guidance regarding how to better secure their infrastructure.

Microsoft Outlines New Initiatives in Ongoing Security Efforts To Help Customers

Press release today:

http://www.microsoft.com/presspass/press/2003/oct03/10-09SecurityInvestmentsPR.asp

Will follow up with more details shortly.

IT Pro Security Zone

This new site was just released on TechNet:

http://www.microsoft.com/technet/security/community/default.mspx

Security MVPs are the main feature of the site. However, any MVP can submit their security related content for publication. Just keep in mind that this is focused more on the IT Pro and not consumers.

Feedback about the site is welcomed.

Security Topics

I find this to be a good list of security topics. You can find this on http://www.microsoft.com/technet/security:


Find in-depth information on security issues.
My Security Blog

I'm not much for keeping journals and there are already lots of methods in place to communicate security issues so I'm not too sure how much I will use this weblog. I will try to keep it up to date as much as possible with things that I think are important to communicate to the security community. These things will more than likely be posted in various security forums, the newsgroups and certain mailing lists as well.

Feel free to send me a note if you have questions about anything!
