Shared cabinet "security"
by Mike Hammett 15 Feb '16

15 Feb '16

I say "security" because I know that in a shared space, nothing is completely secure. I also know that with enough intent, someone will accomplish whatever they set out to do regarding breaking something of someone else's. My concern is mainly towards mitigation of accidents. This could even apply to a certain degree to things within your own space and your own careless techs If you have multiple entities in a shared space, how can you mitigate the chances of someone doing something (assuming accidentally) to disrupt your operations? I'm thinking accidentally unplug the wrong power cord, patch cord, etc. Accidentally power off or reboot the wrong device. Obviously labels are an easy way to point out to someone that's looking at the right place at the right time. Some devices have a cage around the power cord, but some do not. Any sort of mesh panels you could put on the front\rear of your gear that you would mount with the same rack screw that holds your gear in? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

Update your ASAs folks, this is a critical one. -------- Forwarded Message -------- Subject: [c-nsp] Cisco Security Advisory: Cisco ASA Software IKEv1 and IKEv2 Buffer Overflow Vulnerability Date: Wed, 10 Feb 2016 08:06:51 -0800 From: Cisco Systems Product Security Incident Response Team <psirt(a)cisco.com> Reply-To: psirt(a)cisco.com To: cisco-nsp(a)puck.nether.net CC: psirt(a)cisco.com Cisco Security Advisory: Cisco ASA Software IKEv1 and IKEv2 Buffer Overflow Vulnerability Advisory ID: cisco-sa-20160210-asa-ike Revision 1.0 For Public Release 2016 February 10 16:00 GMT (UTC) +--------------------------------------------------------------------- Summary ======= A vulnerability in the Internet Key Exchange (IKE) version 1 (v1) and IKE version 2 (v2) code of Cisco ASA Software could allow an unauthenticated, remote attacker to cause a reload of the affected system or to remotely execute code. The vulnerability is due to a buffer overflow in the affected code area. An attacker could exploit this vulnerability by sending crafted UDP packets to the affected system. An exploit could allow the attacker to execute arbitrary code and obtain full control of the system or to cause a reload of the affected system. Note: Only traffic directed to the affected system can be used to exploit this vulnerability. This vulnerability affects systems configured in routed firewall mode only and in single or multiple context mode. This vulnerability can be triggered by IPv4 and IPv6 traffic. Cisco has released software updates that address this vulnerability. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-… _______________________________________________ cisco-nsp mailing list cisco-nsp(a)puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

algorithm used by (RIPE region) ISPs to generate automatic BGP prefix filters
by Martin T 12 Feb '16

12 Feb '16

Hi, am I correct that ISPs (in RIPE region), who update their BGP prefix filters automatically, ask their IP transit customer or peering partner to provide their "route"/"route6" object(s) or "as-set" object in order to find all the prefixes which they should accept? If the IP transit customer or peering partner provides an "as-set", then ISP needs to ensure that this "as-set" belongs to this IP transit customer or peering partner because there is no automatic authentication for this, i.e. anybody can create an "as-set" object to database with random "members" attributes? This is opposite to "route"/"route6" objects which follow a strict authentication scheme. In addition, in case of "as-set", an ISP needs to recursively find all the AS numbers from "members" attributes because "as-set" can include other "as-sets"? Quite a lot of question, but I would simply like to be sure that I understand this correctly. thanks, Martin

Re: PCH Peering Paper
by Livingood, Jason 12 Feb '16

How does it look when you examine it by not the count of sessions or links but by the volume of overall data? I wonder if it may change a little like 50% of the volume of traffic is covered by a handshake. (I made 50% up - could be any percentage.) Jason >On 2/10/16, 6:34 PM, "NANOG on behalf of Patrick W.
