1. IN FOCUS
(contributed by Mark Joseph Edwards, News Editor, [email protected])
Are you getting enough spam yet? After the long holiday weekend, I checked the email in just one of my mail accounts, and the server reported 76 messages waiting to be delivered. In fact, 38 of them were unsolicited junk mail advertising all kinds of things I don't need, such as an as-seen-on-TV cure for snoring. I don't get nearly as much junk mail in my postal mailbox as I do in my electronic mail boxes, yet I've never opted into anyone's electronic advertising campaigns.
All online advertisers should include a link or email address that we can use to remove our names from their distribution lists (DLs). However, spam sources often use such contact points not to remove names from lists but to verify that a particular email address is valid—which only increases the amount of junk mail I receive.
A few years ago, in a television commentary, Andy Rooney joked that he accumulates piles of his postal junk mail, then ships it all back to the sender with a note that says, "Please throw this away for me." The idea struck me as hilarious, and it might be effective, but I doubt it would work with electronic junk mail.
We can use spam filters to eliminate unwanted email traffic, but keeping the filters effective isn't simple. The task becomes expensive over the long run through filtering software costs and the security-related maintenance hours required. But some relief might be in sight. Recently, the Senate Commerce Committee passed Bill S.630, which, if it becomes law, would make it illegal to send unsolicited email unless recipients have given express consent to receive such communications. In a nutshell, the new law would eliminate "opt out" in favor of "opt in" policies. The proposed law would also let those who receive unsolicited communications file class-action and independent lawsuits against offenders to collect monetary damages. You can read about the bill in the related news story, "Spammers Beware: New Law Seeks Criminal Enforcement" (see the URL below).

On another security-related subject—do you have trouble hiring and keeping security professionals in your company? A recent article in CIO Magazine, "How to Staff Up for Security" (see the URL below), notes that employers have trouble filling available positions because of a lack of skilled and experienced workers in the field: On average, employers fill 1 in 13 available positions.
http://www.idg.net/go.cgi?id=685363
The article lists several ways to attract, hire, and keep quality security people on your staff, including
- knowing your needs and matching them to a candidate
- using specialized headhunters and employment agencies
- making cutting-edge technology available to your security staff
- offering incentives such as yearly training and conference attendance
- considering training inhouse staff for security positions
- paying them well
You probably already know that security professionals don't come cheap. The article states that salaries in the field can range from $60,000 up to $180,000 per year, depending on several factors, including level of responsibility. Be sure to read the article.

2. SECURITY RISK
(contributed by Ken Pfeil, [email protected])
Foundstone discovered a buffer-overflow condition in the Lightweight Directory Access Protocol (LDAP) component of Ipswitch's IMail Server that can result in a Denial of Service (DoS) attack. An attacker can exploit this vulnerability to remotely execute arbitrary code by using the privileges of the IMail daemon, which typically has the default of SYSTEM. Ipswitch has released Hotfix 1 for IMail Server 7.10, which addresses this vulnerability. Users who have earlier versions of IMail Server will need to upgrade to IMail Server 7.10.

4. SECURITY ROUNDUP
The Senate Commerce Committee approved Bill S.630 "Controlling the Assault of Non-Solicited Pornography and Marketing Act of 2001" (the "CAN SPAM Act of 2001" for short). The CAN SPAM act is designed to protect consumers and businesses from unsolicited commercial email (UCE) by levying fines and permitting civil and criminal actions against spammers.

A. The multiuser editing feature of Office XP's version of Word lets you open a locked file, edit the file locally, and merge your changes into the original document. To disable this feature, perform the following steps:
- Start a registry editor (e.g., regedit.exe).
- Navigate to the HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Word\Options registry subkey.
- From the Edit menu, select New, DWORD Value.
- Enter a name of NoPromptToForkDocuments and press Enter.
- Double-click the new value, set it to 1 to disable multiuser editing, and click OK.
7. NEW AND IMPROVED
(contributed by Judy Drennen, [email protected])
BigFix announced BigFix i-prevention, a software support system that protects Windows XP from a security flaw that can expose a PC to outside attackers. The BigFix i-prevention system identifies vulnerable Windows machines, proactively alerts users, and if a user clicks OK, plugs the security hole automatically. Some versions of Windows Me and Windows 98 are also susceptible if the users have installed Universal Plug and Play (UPnP) updates on their systems. Go to BigFix's Web site for a free download. Contact BigFix at 510-652-6700 or

Griffin Technologies announced SecuriKey, a USB-based user-authentication solution for PCs. SecuriKey combines a keylike USB device with password protection. The solution also provides an alternative to public key infrastructure (PKI), protecting companies against unauthorized computer use. For a 200-user network, the cost to deploy would be less than $50 per seat. For more information, contact Griffin Technologies at 800-986-6578 or go to the Web site.

8. HOT THREADS

(Twenty-one messages in this thread)
Gary finds that on some of his organization's PDCs and BDCs, users logging on locally can access shared folders on PDC and BDC servers if three conditions exist. First, the users aren't domain users and have no privileges on any of the servers. Second, they log on by using "workgroup" or the domain name as their workgroup name. Finally, they use a password of "password" (all lowercase). Any user can connect to the BDC and PDC shared directories without permission. Has anyone solved this problem?

Mark has set his password policy on the domain so that after five bad password attempts, the account is locked out. His domain uses roaming profiles. However, if a user's Windows NT 4.0 workstation isn't in the domain, the user can attempt any number of password attempts for a specific domain user without locking the account. How can he lock out the domain account on nondomain systems? Can you help? Read the responses or lend a hand at the following URL:
