While developing the Archive of Our Own, site security is one of our top priorities. In the last couple of weeks, we’ve been reviewing our ’emergency plan’, and wanted to give users a bit more information about how we work to protect the site. In particular, we wanted to make users aware that in the event of a security concern, we may opt to shut the site down in order to protect user data.
Last week we were alerted to a critical security issue in Ruby on Rails, the framework the Archive is built on. We (and the rest of the Rails community) had to work quickly to patch this hole: we did an emergency deploy to upgrade Rails and fix the issue.
As the recent security breach at Twitter demonstrated, all web frameworks are vulnerable to security breaches. As technology develops, new security weaknesses are discovered and exploited. This was a major factor in the Rails security issue we just patched, and it means that once a problem is identified, it’s important to act fast.
Our security plans
If the potential for a security breach is identified on the site, and we cannot fix it immediately we will perform an emergency shutdown until we are able to address the problem. In some cases, completely shutting down the site is the only way to guarantee that site security can be maintained and user data is protected.
We have also taken steps for ‘damage limitation’ in the event that the site is compromised. We perform regular offsite backups of site data. These are kept isolated from the main servers and application (where any security breach could take place).
In order to ensure the site remains as secure as possible, we also adhere to the following:
- Developers are subscribed to the Rails mailing list and stay abreast of security announcements
- We regularly update Rails and the software we use on our servers, so that we don’t fall behind the main development cycle and potentially fall afoul of old security problems
- All new code is reviewed before being merged into our codebase, to help prevent us introducing security holes ourselves
- All our servers are behind firewalls
- All password data is encrypted
What you can do
The main purpose of this post is to let you know that security is a priority, and to give you a heads up that we may take the site down in an emergency situation. Because security problems tend to be discovered in batches, we anticipate that there is an increased risk of us needing to do this over the next month. In this case, we’ll keep users informed on our AO3_Status Twitter, the OTW website and our other news outlets.
Overall site security is our responsibility and there is no immediate cause for concern. However, we recommend that you always use a unique username / password combination on each site you use. Using the same login details across many sites increases the chance that a security breach in one will give hackers access to your details on other sites (which may have more sensitive data).
We’d like to thank all the users who contacted us about the latest Rails issue. If you ever have questions or concerns, do contact Support.
