  • Aside from SMS/email, which should be avoided anyway for other reasons, or proprietary solutions like MS’ or Steams approach, there is nothing to be gained from TOTP or WebAuthN.

    TOTP (the 6 digit code that changed every 30 seconds, usually) is just a hash of a shared secret between you and the server, and the current time rounded to the nearest 30 seconds.

    WebAuthN/FIDO2/U2F is private by design. Keys/authenticators derive a unique key for every credential pair, you can even register the same key multiple times because of this. About the only thing you gain is knowing what type of authenticator is being used, which is of questionable value at best.







  • Well I was expecting some form of notification for replies, but still, seen it now.

    My understanding of this is limited having mostly gotten as far as you have and been satisfied.

    For other bouncers, there’s actually a few decisions you can apply. By default the only decision is BAN which as the name suggests just outright blocks the IP at whatever level your bouncer runs at (L4 for firewall and L7 for nginx). The nginx bouncer can do more thought with CAPTCHA or CHALLENGE decisions to allow false alerts to still access your site. I tried writing something similar for traefik but haven’t deployed anything yet to comment further.

    Wih updates, I don’t have them on automated, but I do occasionally go in and run a manual update when I remember (usually when I upgrade my OPNSense firewall that’s runs it). I don’t think it’s a bad idea at all to automate them, however the attack vectors don’t change that often. One thing to note, newer scenarios only run on the latest agent, something I discovered recently when trying to upgrade. I believe it will refuse to update them if it would cause them to break in this way, but test it yourself before enabling corn




  • You can use a custom origin certificate, but that’s irrelevant when CloudFlare still re-encrypt everything to analyse the request in more detail. It does leave me torn when using it, I don’t use it on anything where sensitive plain text is flying around, especially authentication data (which is annoying when that’s the most valuable place to have the protection), but I do have it on my matrix homeserver as anything remotely important is E2EE anyway so there’s little they can gain, and with the amount of requests it gets some level of mitigation is desirable
