Endpoint Security and Smartphones
Some time back, the FBI was heard to say in public that draw-your-passpattern security, as seen on Android smartphones and tablets, was too much for them, at least as long as you kept your screen clean of skin oil. :-) Whether or not that's true, there are apparently ways to attack even that, using just the sensors on the platform. Specifically, the accelerometers (which are actually usually just angle sensors): http://www.schneier.com/blog/archives/2013/02/guessing_smart.html If you're responsible for security, BTW (and if you're on NANOG, you probably are), Bruce Schneier should be on your daily bookmark list... even if you think he's full of crap.

RE: Endpoint Security and Smartphones
Kind of seems to me that if I am deep enough in your mobile device to get your accelerometer data, I probably can get access to your stored data in the device. The only reason I think I would want your passcode would be to physically steal your device and then try to use it. This is one of those attacks that is probably possible but not practical.

RE: Endpoint Security and Smartphones
My knowledge on mobile device security is pretty limited. I am just trying to wrap my head around the value of your passcode. I suppose it would be good to know if I could get covert access to the device itself so I could see what is on it. I would however have to get some malicious code on the device to get the passcode so it would seem to be easier to put malicious code on your device that sends me whatever I need the passcode to access in the first place. I guess one of my thoughts on computer security in general is that if someone gets physical access to the device, it is history. I would not count on the passcode to be very protective because it would seem that there would be some kind of way around it through the hardware vendor, maybe not but someone would have to convince me that a backdoor does not exist.

Re: Endpoint Security and Smartphones
Normal apps can usually get the accelerometer data without breaking device security.

RE: Endpoint Security and Smartphones
I get that part. I guess I am just trying to figure out why having your passcode is such an advantage. I guess if you really want to physically steal (or temporarily "borrow") my phone and get into it, that would be useful. I would be much more concerned about remote exploits because I have always assumed that if you physically have the device, you are going to get into it. All I count on my passcode for is to prevent me from butt dialing. I think the real value here would be if it were used as more of a general purpose key stroke grabber that could tell me remotely what you are doing with your phone. Problem with that is that the accuracy would have to be much better for that purpose.

RE: Endpoint Security and Smartphones
Well, I guess it all goes back to my original assumption that unless you control physical access to the device there really is no security. Unless someone can prove to me that the pass code is a part of a cryptographically secure system (which is unlikely given the key length of the passcode) that guards the entire file system of the device, then it is nothing more than a lock to keep kids out and prevent butt dialing. This is no different than losing physical control of your laptop computer or desktop machine. Unless you have implemented some of the most draconian security measures including full file system encryption with a removable key store (like a smartcard or such), loss of the physical device is game over in most cases. I think this attack might have value if aimed at a single individual target with a high value reason for needing access to the phone (think CIA going after a high value target). To write an app that randomly grabs pass codes from the general public is a lot less useful because the pass code does nothing for me without the physical device. I still cannot figure out the practical value of this is other than demonstrate that having all of these sensors on your person is a security threat.

Well, certainly it's stored on there, but the received wisdom is that it is somewhere where apps not granted superuser by the user can't reach it, so a "normal" trojan couldn't get to it. It is, of course, in the FBI's best interest to lie about whether they can break this sort of security... But in fact, the point of the pass-swipe is that no, physical access is not enough -- as long as you're not the "disassemble the device and put the flash memory on a scanning-tunnelling microscope" class of attacker; there probably really are uses for this attack.

Anyone know of a good InfiniBand vendor in the US?
Hello NANOG, We are thinking of utilizing some InfiniBand stuff for some specific application in our data centres. We are new to InfiniBand however so we want to get some equipment and see if it does what we need. Does anyone know of a good vendor in the US? East or West coast, doesn't matter.

bidirectional fiber inline amps.
Due to some bundle size restrictions, we are looking at converting some runs over to use bi-directional fiber sfp's (the Cisco version is GLC-BX-D/GLC-BX-U). However a couple of our runs are farther than the spec 6.2 miles. Is anyone aware of a vendor that makes an inline bidirectional amp for this sort of application?

regarding 188.24.168.0/21
Hi list Any help will be appreciated, it seems that apple is filtering prefixes for untraceable reasons I wrote emails to apple-...@apple.com dr...@apple.com but no answer. Staring about 2 weeks ago we encountered several complaints from our customers which are using 188.24.168.0/21. The prefix is allocated to our residential customers, dynamically via pppoe. Actually they are not able to connect AppStore and associated resources like developer.apple.com from their IOS terminal phones or tablets, nor using iTunes or browser from their respective operating systems. Using tcpdump we saw that 17.154.66.17 is not responding to client request. IP 188.27.253.245.63289 > 17.154.66.17.443: tcp 0 Furthermore we did manage to ping hosts from 188.24.168.0/21 using a looking glass server (4.69.185.226) from LEVEL3 San Jose which seems to be last hop provider to apple network.

Oh by vendor I mean VAR I guess. Mostly I'm also wondering how an IB network handles IPoIB and how one uses IB with a gateway to layer 3 Ethernet switches or edge routers.

My limited IB experience has been that the IB switch acts much like a dumb ethernet switch, caring only about which IB hardware addresses are reachable via which port. Routing between IPoIB and IP over ethernet can be done by any host with interfaces on both networks and IP forwarding enabled. In our setups, we've used IPoIB, but with 1918 addresses and not routed beyond the IB network. -- Jon Lewis, MCP :) | I route Senior Network Engineer | therefore you are Atlantic Net| _ http://www.lewis.org/~jlewis/pgp for PGP public key_

I've used them at a previous employer, mainly for PRI termination but also for some transit and colo services. They were decent. Didn't have any major complaints.

An Internet kill switch is a nightmare. We can't even figure out how to run a relay radio system for national emergencies.. Now we are going to assume the people who were owned can somehow shut off communications? We as Americans have plenty of things we have done halfass.. I hope an Internet kill switch doesn't end up being one of them. Build your own private networks, you can't get rooted if someone can't knock. Simple as that. >From my Android phone on T-Mobile.

This is more of news amusement rather than news worthy. Question here should be how much of this is another effort to get a "kill switch" type bill back.

Re: switch 10G standalone TOR, core to DC
I have fairly extensive experience with the Quanta LY2 10GE switches, and they work very well for some environments. Here are some basic impressions: - Broadcom Trident chipset - Similar performance to other Trident switches (ideally line rate, but small buffers) - Cisco-like configuration interface (similar, not the same) - Custom Linux kernel and OS - Basic look-and-feel, but so far the quality has not been a disappointment - Decent support for topologies with no Spanning-Tree - Good compatibility with SFP+ transceivers, direct connections, and optics from various sources. - Basic feature set (OSPF/RIP, but no BGP) - Somewhat limited troubleshooting and debug tools One very pleasant aspect of working with Quanta is that they are very responsive to feature requests, often working closely with customers. On the other hand, their release schedules are somewhat non-specific. I've been waiting for full MLAG support for a while (it's supposedly right around the corner). They are particularly convenient if you are putting them at the top of racks full of Quanta servers, since they have logistics and full-rack staging/shipping. I wish they had better MIB support, BGP, scriptability, and policy-based routing, but they don't. They are cheap enough, however, that you may be able to get two LY2 switches for the price of one of some of their competitors. -- Dan Sneddon On Tuesday, February 19, 2013 at 8:21 PM, Bao Nguyen wrote: > Anyone have worked with the switching vendor Quanta for their 10ge switching > as > TOR?
