    that`s why the answer to this is "Multilayer security", not only traffic to and from browser but also endpoint itself.

    yeah seems like getting info through a proxy where they just do file/packet analysis would be relatively easy, as he explains just mask the data and re-assemble it in the browser-pc lol
    "we will release an open-source attack toolkit for researchers and red teams to test these attacks on their security solutions and better understand their security exposure."
    thats pretty cool

    Great talk.
    Yes it is simple, you said so yourself. You've elegantly and transparently laid out the fault in secure web gateways. The same could be said for most firewall features as well.
    Agreed with your conclusion on the gaps but not the solution. You state that AV's (or EDRs) cant adequately defend this at 2:31.
    Do you have reason to suspect that a more capable endpoint protection cant do the same protections your proposing your browser/extension would?

    People code like maniacs, generate lots of bugs, screws up the hierarchy of data and code, or just padding, unfinish code structures, etc. A lot Programs/Apps these days are a big messy spaghetti that nobody wants to debug with patient, way too many errors to fix. And nobody talks about this

      Security is only a concern when something breaks

    29:35 Another approach would be interleaving chunks, eg split into N chunks where the first chunk contains bytes whose index is 0 mod N, second with index 1 mod N, etc. Then you guarantee that a single request is not enough context to identify the file.

    The SWG lets all these attacks through but what about the client browser itself? Surely some of them could be detected?

    • @Tastybiscuit64
      @Tastybiscuit64 หลายเดือนก่อน

      That's literately what hes showing during the entire 47 minute talk.
      Hes proving that its an architectural issue. That you need to be in the browser (or the browser itself) to defend adequately. His company is building and selling product that as an alternative to SWGs.

    When he says the code is open source, is he just saying the browser.security page is public? Lol
