back to article HTTP/2, Brute! Then fall, server. Admin! Ops! The server is dead

On Tuesday, Netflix, working in conjunction with Google and CERT/CC, published a security advisory covering a series of vulnerabilities that enable denial of service attacks against servers running HTTP/2 services. HTTP/2, like earlier versions, governs the application layer of the internet stack; it runs atop the transport …

    I'm sorry, but that name just creased me up!

    You should totally have a virtual tipjar on Crowdfunder or whatever to get a few beers in for your sub(s) or whoever writes the headlines. "Then fall server!" It's the TavisO of headline writing.

    Please do set up a crowndfunder to get a few beers in for your sub(s) or whoever writes the headlines. That one's a work of art.

    But... but... Google designed HTTP/2 to be secure!

      Given the list of CVEs I'm not sure that there can even have been a requirements specification.

      Seems to me that some^H^H^H^Heverybody in the design department needs to go back to school.

      They designed it to be more efficient at delivering ads. Resistance to DoS attacks wasn't a consideration.

        After all, Resistance is Futile.

      Absolutely no one who isn't authorized can even access it. How much more secure can it be?

    Any client doing any of these things

    should be blacklists & reported upstream to blacklists.

      Re: Any client doing any of these things

      Good idea until...

      My Netflix is not working.

      You have a virus that is attacking our servers.

      No I don't.

      Yes you do.

      Cancels subscription because everything else works OK.

      The virus turns out to be a pawned router, rougue client on WiFi, random user on public / cloud AP, a dodgy app on a mates phone that you allowed to connect, the previous holder of the IP address dynamically assigned by your ISP etc.

    Someone really needs a refresher.

    I really dislike the wording of parts of this article.

    HTTP and HTTP 2 do not “govern the application layer of the network stack”.

      Re: Someone really needs a refresher.

      Nor is TCP "the transport layer" or IP "the network layer".

      The OSI model does not fit TCP/IP well. It doesn't fit anything well, except rump OSI implementations such as ISODE.

      More importantly, if a reader doesn't know what HTTP/2 is, the sort of handwaving gloss that's used in the article will be no help whatsoever. It's neither correct nor usefully incorrect.

    Hardly a surprise

    HTTP/1.1 is a badly stovepiped protocol - but then most communications protocols are, because protocol design is difficult. Also, new protocols have to be relatively uncomplicated to get traction, which inevitably means that if they become popular they'll see new use cases and feature creep which complicate the original design.

    HTTP/2, on the other hand, is a ghastly mess from the ground up. It was rushed through the IETF to jump on a Google bandwagon (or, if you prefer, to try to pull the standardization reins on a runaway Google horse). I followed some of the HTTPbis mailing list discussions for a while, but they were too depressing to continue with. All other concerns sacrificed on the alter of pushing more "content". It's almost enough to make me miss SNA.
