1. IN FOCUS
(contributed by Mark Joseph Edwards, News Editor, [email protected])
Have you seen Microsoft's "5-Minute Security Advisor" documents? According to the company's TechNet site (where you'll find the documents), "The 5-Minute Security Advisor series has been created to help quickly communicate important security topics, tasks, and issues. The advisor will point to the content necessary to go deeper into technical details or into step-by-step, how-to guides."
The series currently includes 15 documents divided into four levels, with each level based on users' situations, expertise, and needs. You'll find security-related documents for small office/home office (SOHO) and home users, power users, IT professionals, and network and systems administrators. Available documents cover a range of subjects:
- Simple Firewall Setup for Home Office Users
- Protecting Your Computer Against Compromise
- Configuring Your Computer for Multiple Users
- Getting the Most from Windows Update (Automated Security Assessment and Updates)
- Essential Security Tools for Home Office and Power Users
- Using the Encrypting File System
- Basic Physical Security
- Using the Internet Connection Firewall
- The Road Warrior's Guide to Laptop Protection
- How Windows XP Protects Your Privacy
- How Outlook Security Works
- Configuring Outlook Web Access
- Choosing A Good Password Policy
- Recovering Encrypted Data Using EFS
- Signing Office Objects
As you can see, the list includes a variety of topics—and if you want to see a document about a particular topic that isn't covered, you're invited to submit that topic for the series.
In addition to the 5-Minute Security Advisor documents, Microsoft maintains a long list of "Security How-Tos" that explain various tasks you're likely to perform on Windows-based systems. On the how-to Web page, you'll find dozens of documents that cover various aspects of security for XP, Windows 2000 Server, Win2K Professional, Microsoft IIS, and Microsoft Internet Security and Acceleration (ISA) Server 2000. For example, the IIS section includes information about how to prevent mail relaying through the SMTP connector and how to use IP Security (IPSec) to secure communications between hosts. The XP section includes instructions for sharing encrypted files and for preventing users from running or stopping scheduled services. The ISA Server 2000 section includes information about how to filter Web Proxy cache entries. Although most of the articles have been published and available in the TechNet database for some time, they seem to have been recently updated.
Finally, have you tried Microsoft Software Update Services (SUS)? The service (see the first URL below) is designed to audit a system and determine which patches that system might need. You can learn more about SUS at the first URL below, where Microsoft has posted additional information that includes a Flash-based demo of the service. The two versions of SUS serve individual users (see the second URL below) as well as corporate users. I've seen complaints about SUS posted on various mailing lists. For example, to determine whether a specific patch is missing, SUS checks only registry keys, whereas another Microsoft tool, HFNetChk, checks files to detect versioning or checksum issues that SUS would miss. If you use SUS or a third-party patch-auditing tool instead, please send me an email message about your experience.
I'm not surprised that Microsoft's emphasis on security and trustworthy computing has led to an increased emphasis on security resources. Let me know what you think about these resources, such as the 5-Minute Security Advisor documents, or about other resources you've discovered.

2. SECURITY RISKS
Jelmer and the Security Internals Research Team discovered multiple vulnerabilities in Microsoft Windows Media Player (WMP), one of which could result in an attacker executing arbitrary code on the vulnerable system. Microsoft Security Bulletin MS02-032 (26 June 2002 Cumulative Patch for Windows Media Player) addresses this vulnerability and recommends that affected users download and apply the appropriate patch mentioned in the bulletin. These patches are cumulative and address all previously discovered WMP vulnerabilities.
Mark Litchfield of Next Generation Security Software discovered multiple vulnerabilities in Microsoft Commerce Server 2002 and Commerce Server 2000, each of which can run an attacker's choice of code. Microsoft Security Bulletin MS02-033 (Unchecked Buffer in Profile Service Could Allow Code Execution in Commerce Server) addresses this vulnerability and recommends that affected users download and apply the appropriate patch mentioned in the bulletin. These patches are cumulative and address all previously discovered vulnerabilities in the affected product.

4. SECURITY ROUNDUP
Incoming European Union (EU) Competition Directorate-General Philip Lowe warned Microsoft yesterday that its upcoming security plan, Trustworthy Computing (code-named Palladium), shouldn't exclude the company's competitors. Speaking at a conference sponsored by the American Antitrust Institute, Lowe said that the EU will ensure that "\[Microsoft\] competitors have the capacity to offer the range of services they want to provide, including security. We have always emphasized ... interoperability."
Malicious intruders use literally hundreds of methods and tools when they attempt to compromise PCs. Some attacks are technically sophisticated and require the skills of a learned intruder. But more and more often, worms and Trojan horses automate external attacks that scour the Internet looking for vulnerable machines. Attackers use compromised machines as a staging area for more attacks against new machines. In this article, Roger Grimes outlines some of the more common attack types you're likely to experience.
5. INSTANT POLL
The voting has closed in Windows & .NET Magazine's Security Administrator Channel nonscientific Instant Poll for the question, "Do you think that open source software (OSS) is less secure than closed source software, such as Windows?" Here are the results (+/2 percent) from the 416 votes:
- 20% Yes
- 73% No
- 7% Not sure
The next Instant Poll question is, "Have you or has your company experienced credit card information theft through the Internet?" Go to the Security Administrator Channel home page and submit your vote for a) I have experienced Internet credit card information theft, b) My company has experienced Internet credit card information theft, c) Both have experienced Internet credit card information theft, or d) Neither has experienced Internet credit card information theft through the Internet.

A. Before Microsoft developed the Microsoft Management Console (MMC) Active Directory Users and Computers snap-in, administrators used the User Manager for Domains tool to manage user accounts. You might still need to administer a Windows NT 4.0 domain from Windows 2000 or NT 4.0 clients, which can lead to problems when you try to add or remove user accounts from the "Grant To" list in the User Rights Policy dialog box and result in the following error message:
"You may not remove the local logon right from the Administrators local group. Doing so will disable all local administration of this computer."
This error can result from the following conditions:
The "Grant To" list you're attempting to modify contains a deleted user or group. To resolve this problem, you must log on to the PDC of the NT 4.0 domain and use the local User Manager for Domains tool to remove the deleted account or group from the "Grant To" list.
