Fwd: Host scanning in IPv6 Networks
by Fernando Gont 24 Apr '12

24 Apr '12

FYI -------- Original Message -------- Subject: IPv6 host scanning in IPv6 Date: Fri, 20 Apr 2012 03:57:48 -0300 From: Fernando Gont <fgont(a)si6networks.com> Organization: SI6 Networks To: IPv6 Hackers Mailing List <ipv6hackers(a)lists.si6networks.com> Folks, We've just published an IETF internet-draft about IPv6 host scanning attacks. The aforementioned document is available at: <http://www.ietf.org/id/draft-gont-opsec-ipv6-host-scanning-00.txt> The Abstract of the document is: ---- cut here ---- IPv6 offers a much larger address space than that of its IPv4 counterpart. The standard /64 IPv6 subnets can (in theory) accommodate approximately 1.844 * 10^19 hosts, thus resulting in a much lower host density (#hosts/#addresses) than their IPv4 counterparts. As a result, it is widely assumed that it would take a tremendous effort to perform host scanning attacks against IPv6 networks, and therefore IPv6 host scanning attacks have long been considered unfeasible. This document analyzes the IPv6 address configuration policies implemented in most popular IPv6 stacks, and identifies a number of patterns in the resulting addresses lead to a tremendous reduction in the host address search space, thus dismantling the myth that IPv6 host scanning attacks are unfeasible. ---- cut here ---- Any comments will be very welcome (note: this is a drafty initial version, with lots of stuff still to be added... but hopefully a good starting point, and a nice reading ;-) ). Thanks! Best regards,

risk bearing/calculation for security service provider
by Ganbold Tsagaankhuu 24 Apr '12

24 Apr '12

Hi, I have some questions related to the security service that security SP offers. Is it common for SP to include risk related calculation into the security service (in contract/SLA) they offer? The question or problem might arise when some incident happened even the customer got secure hosting service from security SP. The customer might complain that SP doesn't protect them well and ask for some penalty in this case. So how does SP protect themselves in this case? Is there any best practice for that? thanks a lot, Ganbold

Automatic IPv6 due to broadcast
by Anurag Bhatia 23 Apr '12

23 Apr '12

Hello everyone Just got a awfully crazy issue. I heard from our support team about failure of whois during domain registration. Initially I thought of port 43 TCP block or something but found it was all ok. Later when ran whois manually on server via terminal it failed. Found problem that server was connecting to whois server - whois.verisign-grs.com. I was stunned! Server got IPv6 and not just that one - almost all. This was scary - partial IPv6 setup and it was breaking things. In routing tables, routes were all going to a router which I recently setup for testing. That router and other servers are under same switch but by no means I ever configured that router as default gateway for IPv6. I found option of "broadcast" was enabled on router for local fe80... address and I guess router broadcasted IPv6 and somehow (??) all servers found that they have a IPv6 router on LAN and started using it - automated DHCP IPv6? I wonder if anyone else also had similar issues? Also, if my guesses are correct then how can we disable Red Hat distro oriented servers from taking such automated configuration - simple DHCP in IPv6 disable? Thanks -- Anurag Bhatia anuragbhatia.com or simply - http://[2001:470:26:78f::5] if you are on IPv6 connected network!

Securing OOB
by Eric 23 Apr '12

23 Apr '12

Hello, It seems that the current practice is to use a DSL line, as opposed to a modem, for accessing an OOB a console server at a remote colo. From a security standpoint, what do people generally do - trust the console server, repurpose an old linksys box from my house or put in a full firewall? Eric :)

Assymetric routing L3/VZ (FIOS)
by Deepak Jain 22 Apr '12

22 Apr '12

Is anyone else seeing this? DC - DFW back to DC? AFAIK, Verizon-GNI is a customer of L3, so no weird peering issues should be afoot. This adds about 40ms to the R/T time. The path leaving Verizon-GNI (FIOS) goes (seemingly) DC-DC and has lower times (<5ms) unidirectionally.
