For example, the Federal Bureau of Investigation (FBI) said that terrorists use strong encryption and related technologies, such as steganography, to hide and disseminate their communications--once again raising the problem of key escrow and encryption export restrictions. Some people who had already accused pretty good privacy (PGP) of contributing to crime are now making those claims even more loudly. According to Wired News (see URL below), the FBI has installed its DCS1000 software (formerly Carnivore) in the core networks of all consenting tier-1 ISPs across the nation. The FBI can now scan most communications that travel across American-based computer networks for potentially incriminating content. http://www.wired.com/news/politics/0,1283,46747,00.html In addition, corporations are considering monitoring email and Internet traffic even more closely, and federal attention is focusing on free email and mailing list services (e.g., Hotmail and Yahoo) as possible vantage points for terrorist communications. Furthermore, the Bush administration intends to ask Congress for expanded wiretap powers. The expanded powers would make wiretap orders applicable to individuals instead of specific devices owned by an individual. Instead of tapping a specific device, law enforcement might be able to tap any device that a suspect might use--including all of our private telephone and computer networks. Meanwhile, attackers have defaced or denied service to various governmental Web sites in both Israel and Afghanistan. I've received reports this week that attackers defaced the Israeli Prime Ministry's Web site, and the Afghanistan presidential palace Web site suffered Denial of Service (DoS) attacks and had to take the site offline. We stand a good chance of losing some of our civil liberties, especially rights to privacy, and I can't fathom how that's necessary to fight terrorism. Microsoft has released a beta version of HFNetChk 3.2, which lets you check which hotfixes are installed on any machine on the network. You can learn about the beta, including how to download a copy, by reading the message Microsoft posted to our HowTo Mailing List at the URL below. In addition, Microsoft says that it's redesigning its security site, and the company is soliciting suggestions about how to improve the site's content and functionality. Be sure to read the Microsoft message listed in the HowTo Mailing List section of this newsletter under HOT THREADS. http://www.secadministrator.com/ListServ/win2ks-l.asp?A2=IND0109C&L=WIN2KSECADVICE&P=270 Sincerely, Mark Joseph Edwards, News Editor, markat_private 2. ==== SECURITY RISK ==== (contributed by Ken Pfeil, kenat_private) * DOS CONDITION IN MICROSOFT WINDOWS NT 4.0 ENDPOINT MAPPER SERVICE A vulnerability exists in the NT 4.0 remote procedure call (RPC) endpoint mapper service that an attacker can use to cause a Denial of Service (DoS) condition. A problem in the service causes it to fail when an attacker sends a request that contains a particular type of malformed data. Microsoft has released security bulletin MS01-048 to address this vulnerability and recommends that affected users apply the patch provided at its Web site. Microsoft will provide a patch for NT Server 4.0, Terminal Server Edition at bulletin MS01-048 when the patch becomes available. http://www.secadministrator.com/articles/index.cfm?articleid=22481 ******************** ~~~~ SPONSOR: IS YOUR SYSTEM PREPARED FOR THE NEXT CODE RED? ~~~~ The Code Red worm and other intrusions are easily avoided if the latest security updates are identified and deployed with UpdateEXPERT(tm).

( contributed by John Savill, http://www.windows2000faq.com ) A. When you manually create trusts, you can select one of two authentication protocols: - Kerberos -- The Kerberos V5 authentication protocol is the default authentication service for Windows 2000. You use the protocol to verify that a user or host is who it says it is. Trusts between domains in a tree and between the root domains in a forest use this protocol. - NT LAN Manager (NTLM) -- The NTLM authentication protocol is the default for network authentication in Windows NT 4.0 and earlier, but Win2K still supports it (although not as the default). NTLM is a challenge-and-response authentication protocol. A transitive Kerberos-based trust links domains within a forest. When you create a trust between two domains in different forests, you can select only NTLM because Kerberos isn't available for cross-forest trust relationships. This isn't a Kerberos limitation, but a Microsoft implementation limitation. If you use a third-party Kerberos implementation (e.g., MIT), you can use Kerberos for cross-forest trusts. 7. ==== NEW AND IMPROVED ==== (contributed by Scott Firestone, IV, productsat_private) * DETECT AND REPAIR VIRUSES Symantec released Norton AntiVirus 2002--software that detects and repairs a virus automatically, provides automated Internet updates, and integrates with Windows Explorer.
