protected content security

[staff profile] mark
There's a bunch of talk going around right now about the whole issue of content security, and trusting the people who host your content and have access to it. I wanted to talk on that for a moment as it's something that is really important to me.

The only people that are authorized to view protected content on Dreamwidth that they don't otherwise have access to are [staff profile] denise and myself. We are the only people with the proper access level. On top of that, it's not automatic -- in order to view the protected content, every time one of us visits a URL we have to edit it and add "viewall=1" to the end of it. It's a very manual process (for good reason). It's also logged -- and I don't know about Denise, but I review the logs regularly, just like every other security log we have.

The second level of access is for people who have access to the production servers that run Dreamwidth. When someone has the ability to log in to our servers, they have full access to the data on the databases and could in theory access protected content. The only people with server access are again myself and Denise, plus our two sysadmins: [personal profile] matthew, who used to work for LJ (before and during Six Apart), and [personal profile] alierak, who I've known for a decade and I trust completely.

That's it. The four of us.

At some point, it comes down to trust. We need the ability to work on the servers, so there are always going to be a set of people who have the ability to see private data. This isn't something that we can feasibly get rid of, either. The data exists on the servers (that's how we can show it to you and the people who are authorized to see it) and we need access to those servers to maintain them. The data isn't just sitting around visible to us, though -- it's tucked away in the database and requires a lot of manual effort to dig out, unzip, and connect to a user account. We never see post content accidentally.

In the end, I think that the best that I can offer anybody is to be explicit about who has access (and what kind of access they have) and to personally watch the security logs. I watch to make sure we don't have unauthorized access to our servers, and I look for unauthorized access to private data as well. It's part of the routine, and it's something I take very seriously. Having dealt with some problems related to this in the past (on other projects, with other people) it's not something I want to see Dreamwidth have to go through.

I'm happy to talk about this, if anybody has any thoughts, comments, or questions.

I would also point out that server access gives us the theoretical ability to read network traffic (even https) off the wire, not just database content, so there is possibly more at stake there than just protected entries. I can't immediately think of a circumstance in which I would be looking at that type of content in order to do my job, unless I already had reason to believe that the traffic or database entries constituted an attack on Dreamwidth's server resources. I do not work support requests unless specifically asked, and will not access private information to do so. I do try to work on difficult-to-diagnose bugs, but thanks to [personal profile] sophie, it's simple enough to troubleshoot things on a Dreamhack instead.
