- 1. ========== IN FOCUS ==========
-
- Hello everyone,
-
- I haven't bought much over the Internet, and until current trends
- improve, I probably won't buy much in the future. Consumer-based e-
- commerce isn't safe yet. Sure, you can probably trust a handful of
- vendors with electronic transactions, but you're still accepting a huge
- risk because no standard exists for gauging information security
- compliance for e-commerce. You have to accept the vendor's word when it
- alleges that its systems are secure, and in most cases the vendor's
- word about security is backed up with nothing.
- Case in point: Last week, hackers found that several large e-commerce
- sites, including CD Universe, contained major security risks that
- exposed customer information, including credit card numbers. The
- intruders probed some sites and pointed them out. In other cases,
- intruders actually cracked the sites and stole credit card data and
- then held the data for ransom. So who's watching who? The black hats
- are apparently watching everyone and everything that comes into view,
- but where are the white hats to keep the black hats at bay?
- Every time I hear about intruders cracking an e-commerce site, I get
- colder toward making online purchases. The last thing we need is our
- credit card numbers in the hands of a system cracker. So how can we
- help prevent credit card theft without giving up on e-commerce? The
- answer is, we can't. For now, if we use e-commerce, we must accept the
- risk because we don't know which sites to trust and which ones to shy
- away from.
- We need a method to determine which e-commerce sites are secure and
- which sites remain in question. How else can we learn to trust e-
- commerce with a given vendor? Perhaps we need an international
- standards body to develop a system of testing and rating a site's e-
- commerce security. If a Web site passes the required examinations, it
- could display a seal of approval.
- I remember hearing talk about forming a security standards
- organization, but I never heard whether it came to pass. Based on last
- week's discoveries regarding lax security on various e-commerce sites,
- I'd have to guess that either no such body exists or it's being ignored
- by e-commerce site developers.
- If you're aware of any such organization or standards for e-commerce
- security, please share with me what you know. Until next time, have a
- great week.
-
- Sincerely,
- Mark Joseph Edwards, News Editor

- 2. ========== SECURITY RISKS =========
- (contributed by Mark Joseph Edwards, mark@ntsecurity.net)
-
- * LOCAL PROCEDURE CALL ELEVATES PRIVILEGES
- Bindview discovered a serious security problem within Windows NT 4.0.
- Because of a flaw in the API call NtImpersonateClientOfPort, any local
- system user can impersonate any other user on the machine, including
- the LocalSystem account. The problem affects all NT 4.0 systems up to
- and including Service Pack 6a (SP6a). Bindview tested its exploit on
- Windows 2000 (Win2K) Release Candidate 2 (RC2) and found that the
- system was not vulnerable. Microsoft is aware of the problem and has
- released an FAQ, Support Online article Q247869, and hotfixes for Intel
- and Alpha platforms.

- http://www.microsoft.com/security/bulletins/MS00-003faq.asp
- http://support.microsoft.com/support/kb/articles/q247/8/69.asp
-
- * SUPER MAIL DENIAL OF SERVICE CONDITION
- UssrLabs discovered a memory leak that might lead to a denial of
- service (DoS) condition because of the way the service handles client
- data. According to UssrLabs, the software appears to store all client
- data in memory during a session and might not properly handle memory
- allocation and deallocation during a session. The vendor, Nosque
- Workshop, is aware of the problem but has not yet responded.

-
- 4. ========== SECURITY ROUNDUP ==========
-
- * NEWS: IIS CERTIFICATES CAN CRASH NETSCAPE COMMUNICATOR
- A bug in Internet Information Server (IIS) can cause Netscape
- Communicator 4.7 browsers to crash while negotiating encryption using
- digital certificates. The problem affects both Macintosh and Windows
- versions of Netscape Communicator.
- By default, international versions of Netscape Communicator 4.7
- accept 56-bit digital certificates, but IIS 4.0 does not correctly
- support 56-bit certificates. Therefore, when Netscape Communicator
- tries to negotiate the use of stronger 128-bit encryption, the browser
- crashes.

-
- * NEWS: E-LOCK TECHNOLOGIES INTRODUCES ASSURED OFFICE
- Microsoft Office is the most popular office suite in use today. E-Lock
- Technologies' Assured Office enhances the value of Office by adding
- public key infrastructure (PKI)-based digital security to make Office a
- comprehensive e-business solution. The seamless integration of Assured
- Office digital signing and encryption features within Office enables
- organizations to conduct e-business using their existing business
- processes.

-
- * REVIEW: LUCENT TECHNOLOGIES' NEWLY EXPANDED VPN LINE
- In his review for InternetWeek, Salvatore Salamone covers Lucent
- Technologies' newly expanded hardware-based VPN product line. According
- to the review, "The new Secure VPN line offers a price/performance
- range from less than $1000 for a VPN-enabled Pipeline router that can
- handle 50 IP Security tunnels to about $45,000 for an Access Point
- router designed to handle up to 4000 IPSec tunnels and a high-speed
- interface such as OC-3 (155 Mbps)."

-
- * FEATURE: SPEECH RECONITION TECHNOLOGY
- In her feature for Planet IT, Diane Levine discusses voice recognition
- technology and its ever-increasing popularity as a security mechanism.
- Diane mentions a couple useful products for PCs, including SaftyLatch,
- VoiceCrypt, and L&H voice recognition technology.

- * TIP: BEFORE YOU SAY "IT'S SAFE"
- (contributed by Mark Joseph Edwards, mark@ntsecurity.net)
-
- With so many blatant security risks appearing on large e-commerce sites
- lately, I think it's prudent to remind you of a basic security tip that
- most diligent administrators practice. That practice is called double-
- checking your system security.
- After you've built and configured a system (including any custom
- application code), have at least one other party inspect that system
- for security shortcomings before you declare the system safe for daily
- use, especially if third parties have developed applications for your
- system. Although you should inspect any systems yourself, both manually
- and programmatically using the security scanners of your choice, don't
- assume your checks are sufficient. To be safe, consider using a third
- party to check your system.

- 8. ========== HOT THREADS ==========
-
- * WINDOWS NT MAGAZINE ONLINE FORUMS
-
- The following text is from a recent threaded discussion on the Windows
- NT Magazine online forums (http://www.winntmag.com/support).
-
- January 14, 2000, 08:34 A.M.
- BDC or Standard Server?
- I just took a new job and the company has four Windows NT servers. I
- know which one the PDC is. Where do I look to see if the others were
- installed as BDCs or standard servers? Do you have to set up
- replication for a BDC to copy the SAM?
