Volume III - Issue #44
October 31, 2001
A consortium of large corporate and government user organizations are
trying to agree on minimum standards for security skills for system
administrators on three levels. In addition, they are working toward
standards for minimum technical skills for information system security
officers and law enforcement people. If you have a program that you
use and can vouch for, we'd love to include it and you in the consensus
building process. And if you have extensive security knowledge and
lead teams of system administrators and would be willing to help in
reaching consensus, we'd love to have your participation. Send a note
to email@example.com with subject "Training standards" and tell us what
you already use to meet these needs.
And at the end of this note, we include (with permission) an email
from a security professional in a middle-sized organization expressing
a bit of shock at what can happen to the firms that are not so big.

26 October 2001 Holes in GovNetFormer CIA director James Woolsey points out that GovNet, the proposed ultra-secure government computer network, overlooks the problems of insider threats and the growing sophistication of hackers; the network presents an incentive for foes to cultivate helpers with network access.
[Editor's (Murray) Note: As the environment becomes more hostile push your defenses out, pull the crown jewels in, and push them down in the ground. Security measures need not be 100% effective to be efficient. Mr. Woolsey is an intelligence expert, not a network security expert. ]
26 October 2001 Pilots' Data Travels UnprotectedRyanair is recruiting pilots, but they must apply on-line and send their CV and credit card numbers unencrypted. Ryanair says the problem will be fixed soon.
26 October 2001 Detecting Address SpoofingThis article describes four ways to detect address spoofing by examining firewall logs.
25 October 2001 Antset VirusThe Antset virus arrives as an attachment that claims to be a Trojan horse scanner; instead, it sends itself out via Outlook and to any e- mail addresses it finds in PHP, HTM, SHTM, CGI and PL files.
25 October 2001 DoD Implores Contractors to Keep SilentAfter some Defense department contractors issued press statements regarding various orders, officials sent out memos to the private industry contractors urging them to be prudent about the information they make public. Additionally, Air Force acquisition officials are now prohibited from conversing with the media.
24 & 25 October 2001 Security News Portal Closed After DefacementThe owner of the Security News Portal web site has decided to close the site after a cracker defaced its homepage. Though the defacement bears the name of well-known German hacker Kim Schmitz, people believe someone else is responsible.
24 October 2001 Amsterdam Airport Pilots Iris Scanning SystemAt Schiphol, Amsterdam's international airport, citizens from 18 European countries may enroll in a biometric identification program that will expedite security waits. The program uses iris scans to identify travelers who carry cards that contain computerized images that must match the scans. The system does not store information.

22, 23 & 24 October 2001 Windows XP SecurityWith its embedded firewall and hardened architecture, Windows XP appears to have adequate security for average home users. However, there are still some weaknesses, such as a built in firewall that does not block outbound traffic.
22 October 2001 Security Manager's Journal: Security ReviewThe events of September 11th compelled the security manager to conduct a review of security practices at his company. He reviewed access permissions and examined physical security by wandering through various offices looking for poorly hidden passwords and unsecured areas. He also plans to review the company's disaster preparedness and business continuity plans and to test hiring practices with an eye to keeping out those who are trolling for company security information.
21 October 2001 Elias Levy Responds to CulpElias Levy responds to Scott Culp's essay on "information anarchy" and suggests that instead of trying to keep knowledge of vulnerabilities out of the wrong hands, people should make efforts to restrict attack opportunities.
[Editor's (Murray) Note: It should be obvious to anyone that these are not mutually exclusive options. This argument is simply a rationale to do what the vandals intend to do in any case. "Security experts" post work-arounds, not exploits. (Schultz) Elias Levy has spoken well, and others should do the same. You cannot simply suppress information about vulnerabilities to achieve better security. Scott Culp's position on this matter is not only unrealistic, but it is downright frightening---a spokes-person for a prominent vendor is effect preaching "security by obscurity."]
The following note is shared with permission. This last week, I attended the Intrusion Detection Track at the San Diego SANS Network Security 2001 conference, and I have to tattle on myself and relate a funny(?) story from the class. Carl Hopper and myself are both from the medium to large corporate LAN/WAN side of the commercial world, and several things conspire to help us in that world. Although there's quite a bit of SUN/LINUX and NT Server stuff, there's also a vast amount of NetWare/Groupwise/IPX stuff in place. With Internet traffic being IP centric, and hackers being Microsoft centric, a happy accident has left a lot of commercial space a little safer than it would otherwise be. So several times in the conference, Carl and I would debate how big the exposure really was in our typical world. So I must admit, part way through class, I was telling myself this whole intrusion thing was academically interesting and obviously critical to big government, military or academic networks, but probably not such a big deal to us medium, stealthy commercial guys/girls .... Grump, Grump... this is a bunch of B.S., etc.! Sunday night I left the conference and dragged myself back by the office to dump books and check emails. As I got ready to leave the office, I laughingly took the class laptop w/SNORT down to our NOC/DMZ room and hooked it to a test port on the DMZ hub. I was folding up my briefcase when I thought, "I'd better check" to be sure the log directory and alerts.ids file got created. As I double-clicked on log, I stood there horrified as I watched .... "Holy Smokes Batman"..... new directories getting added as the detects started rolling in. Needless to say ... "Take me to the river - Throw me in the water - I'm converted" Thanks Glenn Kennedy
