RE: key change for TCP-MD5

Assumptions, assumptions. If your IPSEC is being done in hardware and you have appropriate QoS mechanisms in your network, you will probably not be able to pass your best effort traffic but the rest should be OK. Can we get back to the regularly scheduled programming instead of throwing big numbers around? Barry had a point, if you do IPSEC stupidly, it does not protect you. If you pay attention to detail, it does help. It is not the panacea. For the purpose of securing BGP, I think IPSEC is easy to configure (at least on IOS which is what I'm used to), and will do the job. And for this application, I don't see why cert's can't be used either.

But it's literally years before that will be usable, especially because both ends of a connection need to be upgraded before it delivers any benefits. That is especially problematic for the interISP case. We both agree that key change is (a) necessary, and (b) very difficult with 2385. The longer-term issue is where "there" his, and that's what your draft addresses; my draft is about how to get from "here" to "there". --Steven M. Bellovin, http://www.cs.columbia.edu/~smb

Tor and network security/administration
by Jeremy Chadwick 22 Jun '06

22 Jun '06

Apologies if this has been brought up before. Being as I'm not a network administrator myself (although I do filter some stuff using pf and ipfw on my severs), I'm curious what NAs think of the following technology: http://tor.eff.org/overview.html.en The problem I see is that this technology will be used (literally, not ideally) solely for harassment (especially via IRC). I do not see any other practical use for this technology other than that. The whole "right to privacy/anonymity" argument is legitimate, but I do not see people using* Tor for legitimate purposes. A colleague of mine stated his opinion of my opinion: "Your problem with Tor is that you can't control it, isn't it?" And he's right -- that's the exact problem I have with it.
