Validating My API Schema as Part of My API Security Practices

A recent breach in the FCC API reminds us that security is an essential concern when creating and maintaining your APIs.

I am spending more time thinking about the unknown unknowns when it comes to API security. This means thinking beyond the usual suspects when thinking about API security like encryption, API keys, and OAuth. As I monitor the API space I’m keeping an eye out for examples of what might be security concerns that not every API provider is thinking about. [I found one recently in ARS Technica, about the Federal Communication Commission (FCC) leaking the email addresses through the CC API for anyone who submitted feedback as part of any issues like the recent Net Neutrality discussion.

It sounds like the breach with the FCC API was unintentional, but it provides a pretty interesting example of a security risk that could probably be mitigated with some basic API testing and monitoring, using common services like Runscope, or Restlet Client. Adding a testing and monitoring layer to your API operations helps you look beyond just an API being up or down. You should be validating that each endpoint is returning the intended/expected schema. Just this little step of setting up a more detailed monitor can give you that brief moment to think a little more deeply about your schema–the little things like whether or not you should be sharing the email addresses of thousands, or even millions of users.

I’m working on a JSON Schema for my Open Referral Human Services API right now. I want to be able to easily validate any API as human services compliant, but I also want to be able to setup testing and monitoring, as well as security checkups by validating the schema. When it comes to human services data I want to be able to validate every field present, ensuring only what is required gets out via the API. I am validating primarily to ensure an API and the resulting schema is compliant with HSDS/A standards but seeing this breach at the FCC has reminded me that taking the time to validate the schema for our APIs can also contribute to API security–for those attacks that don’t come from outside, but from within.
