  1. Re:Not MITM on Ask Slashdot: Does Your Employer Perform HTTPS MITM Attacks On Employees? · · Score: 1

    Bullshit. Proxies handle HTTPS all the time. They can do all kinds of things with it, like see what the outbound IP is, what internal machine it comes from, how much bandwidth is being used (approximate, with an upper bound, but still), what port it's going to (usually 443 of course), how long the connection stays open, and so forth. It can log all that info. It can block connections to undesirable (because of malware / inappropriate user of resources / illegal / whatever) hosts. It can raise flags in the case of too many connections, or too much data, or data at unusual times, or... you get the idea.

    A proxy just routes all the connections through one machine. It doesn't imply a need to be able to read data that flows over those connections. Some *uses* of proxies to require that ability - for example, anti-exfiltration systems that look for sensitive data somebody is trying to sneak out - but those can be fooled by concealing / encrypting the data at the application layer anyhow.

    There's also the (experimental, draft, whatever" standard of "HTTP Public Key Pinning". Same idea as HTTP Strict Transport Security (which is becoming more widely supported, though not yet widely implemented server-side), but where HSTS merely requires that future connections to a given site must be over HTTPS (this blocks things like SSL stripping), HPKP requires that for a connection to the site to be trusted (now or in the future), the thumbprint of its public key (or that of the signing cert, perhaps, for agility) must be as specified in the header.

    Of course, like HSTS, it's a trust-on-first-use scenario; if the proxy begins editing the HPKP headers (which it could do easily; just set them to the cert it's using to intercept all your connections), everything will appear fine until/unless you try connecting *without* that proxy in the way. Of course, if HPKP is implemented (in both client and server) before the proxy learns to handle it, you're going to get a whole lot of certificate errors...

A few others failed in other interesting ways, including crashing the browser.

Google could probably do the same on Windows, and indeed may have done so (I know more 'softies than Googlers). But for Linux? Good luck.

    I think it was MS who had a bug in the past where if I got a certificate issues for "google.com\0.attacker.com", I could present that certificate for a request to "google.com" (due to DNS hijacking or a MitM attack) and it would pass validation because the CN was handled as a C-style string and treated the null byte as a terminator. Fixed long ago, but still. People have been messing up cert validation for as long as it's been around.

    The scary thing is how many mobile apps just don't *do* cert validation. Either it's completely disabled, or they crippled it in some way (I've seen both not checking the trust chain and not checking that the cert is valid for the target site). The usual reasons are "oh, we just did that for testing" (but I'm looking at your release version...) or "yeah, one of the servers it connects to uses a self-signed cert" (fine, add explicit trust *for that cert* but don't just disable chain-of-trust checks!) Another common problem is leaving completely broken or outdated options enabled (export ciphers - 40-bit symmetric crypto, easily breakable with a home PC - ot SSLv2 or other such similarly stupid things).

    Mind you, electrics have their own host of inefficiencies. There's resistive losses (both within and outside the battery), losses to regulation circuitry, some of the same drivetrain losses as a car (avoiding a conventional transmission surely helps, but there is still some friction in the moving bits, as always), and probably a ton of other things I haven't thought of. I can well believe the inefficiencies of a conventional ICE-based car are several times as bad as those of an electric, though, which means a factor of 5x improvement in battery capacity could let batteries substantially beat hydrocarbon fuels on a usable-energy-per-volume metric, and be within one order of magnitude on mass as well.

    Actually, astrology should be pretty falsifiable. I realize it's full of weasel-wording and vagueness, but there still must be claims that can be compared against a control group who doesn't know their "sign" and doesn't give a damn. You don't even need to demonstrate that the claims are *wrong*, per se - although it'd be great if you could - just that they apply equally well to people of other "signs" and/or to people who don't know (depending on whether the claim is a suggestion that you should do something, or that something will happen).

    We have good statistical models for determining whether something is differentiable from randomness, and even better ones for determining whether two groups of events can be said to differ from one another to any degree of confidence. If you want to claim that (for example) two particular astrological signs are more romantically compatible, that should be a dead easy thing to statistically test. Eliminate those couples where either partner paid any attention to astrology, if you want to avoid the risk of that biasing the results.

    This type of statistical analyses of populations is the standard approach of the social sciences. With large enough sample sizes, the error can be very low, comparable to that of observational or "hard" science. For that matter, past a certain point, physics is all statistical modeling anyhow.

    It has nothing to do with organicness. It's simply that produce which is grown "organically" typically has a much shorter shelf life (this is not to say that the ways mass-market produce gets an extended shelf life are good, mind you) and consequently must be picked ripe and sold immediately. Mass-market produce is picked quite unripe and transported long distances, "ripening" (to the extent that they can) in transit, in storage, or simply on the shelves (or, considering the unripeness of a lot of what's on the shelves, on *my* shelves at home). That's what causes the taste difference.

    If you don't believe me, go look up some studies. People have done double-blind taste tests, and found that the "organicness" of food was undetectable, while picking it ripe and eating it quickly made all the difference.

So there's no guarantee that the first mover will have the better software. They will of course still have the first-mover advantage, but that doesn't guarantee success.

    Personally, I favor a compromise. The computer industry moves really fast. A year or so of R&D should not result in a patent that will be in effect for the next 5-10 generations of software and hardware. "Reinvented... ON A COMPUTER!" absolutely should not. But there's something to be said for a short-term protection. Two or three years, maybe five at most, would give people plenty of time to profit from their R&D (before the fast pace of the industry obsoletes them) while still allowing the industry to build on those patented "inventions" and bring new products to market a few years later even if the don't want to pay the licensing costs (note that they could certainly *begin* development prior to the patent expiring, just not release a product using it). Obviously (well, to most people) this should not apply to applications that simply digitize existing algorithms, either, but there's a lot to be said for rewarding the ability to develop new solutions to problems (or creating new markets where people hadn't thought it was possible at all) with a short-term monopoly. Reverse engineering really is quite easy.
