Actually, If a master mirror gets hacked, and an ISO replaced, the modified copy will be rsync'd to the mirrors. So, it's still in people's best interests to (even if downloading over SSL) checksum the ISO -L > On 18/01/2017, at 2:38 PM, Ryan Nix <ryan.nix at gmail.com> wrote: > > The performance hit is negligible, especially for someone like Northwestern that is part of Internet2. We also have a SSD drive pushing the bits on the mirror. Personally, there is no reason not to use SSL wherever possible, especially with Let’s Encrypt being free and automated. There is a reason Google gives preferential rankings to sites that use SSL. Yes, there are checksums on the CentOS ISOs and packages, but how many people actually do that after a download? Using SSL reduces the need to checksums. > >> On Jan 17, 2017, at 7:52 AM, cdnops at as250.net wrote: >> >> Dear Ryan, >> >> I am curious... >> >> which advantages did you intend to get out of the redirect? >> >> imho doesn't offer any increase in security at all: >> >> 1) The packages are signed, so their integrity is protected. >> >> 2) Confidentiality of the request is already broken before the redirect. >> >> 3) MITM/Downgrade can already happen there. >> >> So unless HTTPS becomes standard delivery method or HSTS is honored, >> this is a moot exercise anyway that just leads to lower performance. >> >> If HTTPS becomes the standard delivery method, against which CA base >> will certificates be checked?
