bidirectional fiber inline amps.
by Eric J Esslinger 20 Feb '13

20 Feb '13

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? I did some digging but either they do not exist or my google fu is weak today. __________________________ Eric Esslinger Information Services Manager - Fayetteville Public Utilities http://www.fpu-tn.com/ (931)433-1522 ext 165 This message may contain confidential and/or proprietary information and is intended for the person/entity to whom it was originally addressed.

RE: Endpoint Security and Smartphones
by Naslund, Steve 19 Feb '13

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.

Endpoint Security and Smartphones
by Jay Ashworth 19 Feb '13

19 Feb '13

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.

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.
