==== 1. In Focus: Security Tools: Everybody Has Favorites ==== by Mark Joseph Edwards, News Editor, mark@ntsecurity.net

Handling information security is a tedious task. Having decent tools at your disposal makes the job easier to accomplish. Of course, some tools are more valuable than others, depending on the tasks at hand.

You probably use some of the many security tools available today--to secure cross-network communication links, network borders and segments, servers, workstations, mobile devices, data storage systems, forensics, and more. Tool developers and vendors tout their wares, but what they say about their tools doesn't always provide enough insight into what a hands-on experience with a given tool might be like.

You've probably found choosing which tools to use in a given scenario a challenge. One must review the possibilities, ask for recommendations, then investigate the most suitable tools to see which might meet a given set of needs. Nevertheless, you probably have a few favorites--depending on which tasks you need to perform.

As a publisher of computing-related information, our publications review tools and present information about those tools in as unbiased a fashion as possible. But we can review only a fraction of the many tools available. At the same time, hundreds of thousands of people read our publications, and vast numbers of you have accumulated great hands-on experience with various security-related tools. Because many of you who read this newsletter are probably administrators who deal at some level with information security, I'm asking you what your favorite security tools are.

Given the broad range of security tools available, I plan to leave the question wide open. I've no way of knowing which variables affect your network environment and your work--and thus your choice of tools. Perhaps you depend upon a particularly useful authentication tool, Wi-Fi (the 802.11b wireless standard) tool, encryption tool, Intrusion Detection System (IDS), firewall, packet analyzer, file system analyzer, scanner, Web protection, database protection, log analyzer, or spam prevention technology. Rather than developing a list of possible categories, I'm asking you to nominate the tools that serve you best.

Whether you have one favorite tool or many, you probably like them because they're useful. Your experience can help others who might need such tools.

If you're a security administrator (no developers or vendors, please), I hope you'll take time to send me an email message listing your favorite one or two tools (respond anonymously if you prefer). Prefix the subject of your response with "\[Tools\]" so that I can more easily gather the email messages and tally the results. In the body of the message, please list each of your favorite tools, and for each tool include the tool name; URL for each tool if possible; the platforms it runs on; whether the tool is commercial, shareware, or freeware; and a paragraph about the tasks it handles successfully. After June 12, I'll compile your responses and let you know the results when they're available.

==== 2. Security Risks ==== contributed by Ken Pfeil, ken@winnetmag.com

DoS in Cisco IOS Cisco Systems' IOS software contains a vulnerability that might result in a Denial of Service (DoS) attack. This vulnerability stems from a flaw in the Service Assurance Agent, also known as the Response Time Reporter (RTR). By sending a malformed RTR packet to the router, a potential attacker can crash the router. Cisco has released an advisory and free upgrades for affected customers, which can be obtained through the usual support channels. http://www.secadministrator.com/articles/index.cfm?articleid=39055

==== 4. Security Roundup ====

News: Microsoft Launches Virus Information Center as Deceptive Worm Floods Inboxes Microsoft, Network Associates (McAfee's parent company), and Trend Micro announced that they've formed an initiative called the Virus Information Alliance (VIA), a new way for customers to get information about virus threats that affect Microsoft technology. The VIA announcement is well timed; a new network worm called Palyh is spreading quickly through email and LANs. http://www.secadministrator.com/articles/index.cfm?articleid=39060

Feature: Improve Security with XP's Command-Line Tools If you've rolled out Windows XP in your organization or plan to do so, certain tools will help you monitor, manage, and secure your XP installations. Microsoft has beefed up several familiar GUI and command-line tools and added some new ones. Microsoft has chosen not to ship utilities with the "Microsoft Windows XP Resource Kit." Instead, the company has moved the more useful utilities from the "Microsoft Windows 2000 Resource Kit" and the "Microsoft Windows NT 4.0 Resource Kit" into the base XP OS and into the Support Tools folder on the installation CD-ROM. http://www.secadministrator.com/articles/index.cfm?articleid=25014

Feature: The Security of EFS Encrypting File System (EFS), which Microsoft introduced in Windows 2000, is a surprisingly powerful and robust technology that lets users protect their sensitive data from unauthorized eyes by encrypting it. In "Securing Win2K with Certificate Services," September 2001, http://www.secadministrator.com , InstantDoc ID 22113, John Howie described how Microsoft's public key infrastructure (PKI) product, Certificate Services, worked and showed you how you can improve your network's security by leveraging the service as an Enterprise Certification Authority (CA). In this follow-up article, Howie shows you how to leverage the features that (EFS) offers by tying it into your PKI. http://www.secadministrator.com/articles/index.cfm?articleid=24051

FAQ: What Are the Differences Between Usrmgr.exe and Musrmgr.exe? contributed by Jan De Clercq, jan.declercq@hp.com

User Manager (musrmgr.exe) is a Windows NT Workstation 4.0 tool for managing a workstation's accounts (also known as local accounts). User Manager for Domains (usrmgr.exe) is an NT Server 4.0 tool for administering an NT domain's accounts (also known as domain accounts).

Musrmgr is a reduced functionality version of Usrmgr. When you work with a workstation, many of the options for NT domains don't apply, so you don't need the extra features that Usrmgr provides. Unlike Musrmgr, Usrmgr can be used to administer domain accounts, global groups, and trust relationships.

Usrmgr is the only tool a domain administrator really needs. You can use Usrmgr to manage not only domain accounts but also local accounts stored in the SAM of workstations and member servers. To connect to another SAM, simply choose Select Domain from the User menu. In the resulting dialog box, you can select a domain or type the name of a workstation or member server to whose SAM you want to connect. If you type the machine name, make sure that you precede it with two backslashes.

If your primary computer is an NT workstation and you'll regularly administer domain accounts from this machine, you can install Usrmgr on it. To do so, go to the \Clients\Srvtools\Winnt directory on the NT Server 4.0 CD-ROM on your workstation and execute the Setup.bat file. http://www.secadministrator.com/articles/index.cfm?articleid=25021

==== 8. New and Improved ==== by Sue Cooper, products@winnetmag.com

Remove Risks in P2P File Sharing and IM Applications Akonix Systems announced Akonix Enforcer, software that helps eliminate the security and corporate liability risks associated with unsanctioned peer-to-peer (P2P) file-sharing and public Instant Messaging (IM) applications. Using a protocol signature matching technology, the software blocks unsanctioned file transfers from entering or leaving your network through P2P and IM, protecting your company from potential liability for copyright infringements, for excessive bandwidth consumption, and for the transmission of viruses, Trojan horses, or installed spyware. Akonix Enforcer will be available in early June. Contact Akonix Systems at 619-814-2330 or sales@akonix.com. http://www.akonix.com

Inoculate Windows 2003 Panda Software announced Panda Antivirus for Windows Server 2003. The software operates in both 32-bit and 64-bit environments and adapts to the Active Directory Service (ADS) in Windows 2003. You can detect and disinfect viruses even in Encrypting File System (EFS) files. Features include automatic daily updates and centralized and remote management. The real-time scanner's core engine is multithreaded and uses multiple channel scanning technology optimized for parallel scanning on multiprocessor servers.

Featured Thread: Continuous Password Attacks (Two messages in this thread)

A user writes that he's administering a Microsoft Exchange 2000 Server with Microsoft Outlook Web Access (OWA) enabled. Continuous failed attempts from various IP addresses to log on as Administrator and with other usernames (about five attempts per hour, about 10 usernames being rotated) seem to indicate a concerted effort to break in by guessing passwords. Apart from blocking the offending IP addresses in his router, does anyone have a good strategy to deal with this type of attack? His company doesn't want him to disable OWA.
