Forgot your password?

Comment Re:It is "a random hash" (Score 1) 251

It would be bad form to reset the password when anyone clicked 'reset this accounts password' anyway. So until the link is followed, no action should be taken with regard to the account password anyway. This way a malicious person can't just denial of service a valid account by clicking 'reset my password'.

This means if an attacker is able to intercept your SMTP, they could still hijack your account through requesting a password reset at will, so it's not perfect, and yes some 2 factor authentication would be nice *if* it were an important site. Account creation needn't have this particular hole, just password reset.

If you didn't want to SMS, you could use TOTP (e.g. google authenticator is one implementation, but not the only one). Though either way that's something to potentially lose so it would be a suggestion option for those increasing security.

The idea is that the user set his password via (presumably) secure https. The purpose of the random hash is so that you provide the legitimate email user a transient secret that must be used *in conjunction* with the password they had chosen (or some session cookie sent via https to avoid making them log in twice when clicking on the email).

So here the password is to authenticate that the original person that accesses the site, the hash authenticates a valid email account. Both together are required to verify the account is valid. This way someone intercepting SMTP doesn't get access to hijack account and someone without a valid email can't get an account activated.

Comment Re:systemd (Score 1) 383

eth0 being renamed to biosdevname and then 'consistent' device naming happened outside of systemd per se. It's one of the various questionable things that came along at about the same time as systemd, and systemd gets the blame for *all* of them, when it only brought some of it. E.g. complaining about binary logs, you can aim that square at systemd. Most of the other prominent rants commonly fired at systemd are either dbus, networkmanager, udev, or something else in reality.

The network device naming is one facet where they can't win. The ethX has problems, and so does the current state of consistent device naming (notably that if an adapter veers off into being enumerated by pci, it's probably a lost cause in all but the most extremely homogenous environment and doing those names is just causing more trouble than helping)

Comment Re:He answered the most boring questions! (Score 3, Interesting) 187

I agree that Torvalds isn't the authoritative god of all that makes up a distribution and as such his opinion is one to be considered, but no the only one.

Also he speaks to the biggest fundamental controversy, the log strategy/format. I agree with Torvalds, that the capabilities of systemd are interesting, but I personally find the bathwater that comes with it troublesome enough to not want it. That and how they engage with the community at times. A lot of the other gripes about systemd are more implementation mistakes that are unintended and often addresed, but this part is very explicitly intentional and counter arguments have been dismissed out of hand.

Sometimes you don't have a choice in an interoperable piece of software. In an aggresive world that tosses away backwards compat in the name of security, you'd either have to toss out a bunch of perfectly ok equipment because you *can't* talk to it anymore, or stick to outdated software to protect the investment, which may have unfixed vulnerabilities because the versions that fix things also dropped support for your needs.

All the known broken facets of MD5 have zero applicability to HMAC usage scenario. The only part of it that weakens HMAC is that SHA256/SHA512 are more computationally expensive.

If someone knows a weakness in HMAC-MD5, it's hard to imagine it would be related to any of the known broken parts of MD5, and thus HMAC-MD5's chances of being broken might not be so different than any other HMAC use of a hash.

Yes HMAC-SHA2 is the best choice now. Now it's not a good reason to go nuts over things that use HMAC-MD5 today.

This organization would just be responsible for verifying that software is secure

That was my assumption going in. I'm saying that 'verifying that software is secure' is a complex beast that I don't think is such a trivial undertaking. I was thinking of a company that has a 'development' team and a 'security' team, which I have experience in. The security team generally devolves into effectively black box testing of a system without understanding the real purpose and potentially fishy stuff going on internally that will pave the way to future vulnerabilites. CyberUL would be in those shoes, doing largely black box testing because there is no way they could do full code audits. Sure they can probe it or demand source code to do some analysis tools on it, but the most notorious security problems have mostly been around new discoveries about widely deployed technology that had previously *eluded* such analysis that is already prevalent in the industry.

It may be good to have a CyberUL to formalize already known best practices, but I don't think it's going to get what people want out of it.
