Date Sun, 26 Aug 2012 19:47:44 GMT
+1 on preserving the provenance and integrity of binary dependencies.

I'd go with external signatures *and* hosting the specific artifacts on a reliable ASF location
for preservation along with all ASF project sources that depended on those specific artifacts
in any sort of review, release of authenticated binaries, etc.

Note that this move is exactly the wrong thing to do if we want have
buildbots build binaries that are assumed to be safe and therefore
signable.  Instead of the security and verifiability of ASF-run host,
we're putting the dependencies off to a dozen different remote sites,
with no visibility into their site's mechanisms for vetting changes,
access controls, auditability of changes, even basics like ensuring
domain names are renewed and not poached by others.

Do we really think other websites are as secure as the ones that Infra
operates?  If so we should move the source code to the other sites as
well, right?

No easy resolution of this, but we might mitigate the risk by putting
all of the dependencies to Apache-Extras and load from there
primarily.  And if at all possible make sure all change notifications
from there get echoed to the ooo-committs lis.   We have a better
chance of exercising now screwing up if we control rather than having
multiple 3rd parties control.

Another option would be to use cryptographic means to ensure the
integrity of the remote dependencies, e.g., detached signatures. That
doesn't protect us from another website going down, temporarily or
permanently, but it does allow us to verify that what we are
downloading has not been tampered with.
