Wow, just when you though big government was someone else's problem
by Jeff Young 05 Apr '09

This comes from Lauren Weinstein's list and it's worth a read. It's a bill introduced into legislation, who knows where and when and if it will become law but, wow. http://lauren.vortex.com/Cyber-S-2009.pdf I'll just give you a teaser: SEC. 9. SECURE DOMAIN NAME ADDRESSING SYSTEM. 3 (a) INGENERAL.—Within 3 years after the date of 4 enactment of this Act, the Assistant Secretary of Com- 5 merce for Communications and Information shall develop 6 a strategy to implement a secure domain name addressing 7 system. The Assistant Secretary shall publish notice of the 8 system requirements in the Federal Register together with 9 an implementation schedule for Federal agencies and in- 10 formation systems or networks designated by the Presi- 11 dent, or the President’s designee, as critical infrastructure 12 information systems or networks. 13 Other pearls of wisdom: the government will license all "cyber" security folks and you don't work on government or "any network deemed by the president to be critical infrastructure" without one. If only we knew: to achieve a secure DNS all you need to do is publish a notice in the Federal Register. jy

Spoofer project update
by Robert Beverly 05 Apr '09

05 Apr '09

Hi, as many of you are acutely aware, IP source spoofing is still a common attack vector. The ANA spoofer project: http://spoofer.csail.mit.edu first began quantifying the extent of source verification in 2005. We've amassed several years worth of data -- data that has become particularly interesting in light of recent attacks. However, our data raised as many questions as it answered. Hence, we have developed a new version of the tester designed to answer these questions and improve our Internet-wide inferences. What's New: In addition to new tests, we've hooked into CAIDA's Ark infrastructure which allows us to perform multiple path-based measurements. This information is presented to the client now in visual form; see the screenshots for an example report: http://spoofer.csail.mit.edu/example/example.php How you can help: Simple -- take a few minutes to download and run the tester. The more points you can run the tester from, the better. Comments/Flames: Welcome, and we appreciate all feedback. Be sure to read the FAQ: http://spoofer.csail.mit.edu/faq.php Many thanks, rob

Re: Nipper and Cisco configuration results

I did see a few false positives too with Nipper. What do you think about Router Audit Tool (RAT) instead? I downloaded ncat (aka RAT), but it does not have a global configuration file which I can use for all the routers and switches I have. Any tips on ncat/RAT configuration? I could not find any examples on using ncat.

You might or might not have the rlogin service enabled, but nipper has so many false positives I find is almost useless. In my case, it caught some obvious things I had forgotten to do, but everything else was useless. For instance from the nipper source code: struct vulnerability report_vuln_ios11 = {9, 0, 0, 12, 4, 0, "CVE-2007-0479", "22208", "IPv4 TCP listener denial of service", true, false, vuln_req_none, false, &report_vuln_ios12}; What the above means to nipper is any IOS version 12.0.x, 12.1.x, 12.2.x, 12.3.x is vulnerable, while every 12.4.x version is OK. This is obviously false on *both* counts. http://www.cisco.com/en/US/products/products_security_advisory09186a00807cb… I spent a lot of time trying to explain this to $corporate audit guy that had never even logged into a router, let alone had to choose a stable IOS version for 6500/7600 class hardware. > Here is the Nipper's output: > <snip> > Thank you in advance for any help. > > Subba Rao -- Christopher McCrory "The guy that keeps the servers running" chrismcc(a)pricegrabber.com http://www.pricegrabber.com To the optimist, the glass is half full.

I looked at the configurations yesterday on the routers. The vty line does not have any "transport" line below it. All the routers showing "Rlogin enabled" have similar configuration. What are the default services that are enabled for vty on IOS 12.4? I know there are only telnet, SSH and Rlogin. Is there any particular sequence that IOS processes the vty access?

BGP and ios upgrade question
by srg 03 Apr '09

03 Apr '09

Hello: A little customer has a Cisco 1841 router running ios 12.3(8r)T8. At the end of this mail is a "show version" from the router. Now, he wants to run BGP. His current ios version 12.3(8r)T8 does not support BGP. According to Cisco feature navigator, ios version 12.4(24)T (c1841-ipbasek9-mz.124-24.T.bin) can run in the 1841 and supports BGP (note that feature set is IPBASE): http://tools.cisco.com/ITDIT/CFN/Dispatch?act=feature&imageid=1321931&platf… 12.4(24)T requires 128MB DRAM and 32MB flash Remote peers will announce ONLY the default route to the 1841 My questions are: 1) It is common that a version with an IPBASE feature set supports BGP (some docs says that bgp support is included in "SP" services feature set)? 2) Will ios version 12.4(24)T run OK in the 1841? I think the response will be YES because Cisco feature navigator says that it is supported and the router has the DRAM and FLASH needed by 14.4(24)T. 3) Must the customer pay in order to download 12.4(24)T or he can download if he has a valid Cisco maintenance contract for that router? ------------------------------- show version Cisco IOS Software, 1841 Software (C1841-IPBASE-M), Version 12.3(8)T8, RELEASE OFTWARE (fc1) Technical Support:http://www.cisco.com/techsupportCopyright (c) 1986-2005 by Cisco Systems, Inc.
