Description
It's currently possible to log CSRF exceptions with the 403 handler. But a more sensible default would be to log them by default. This would be an easy simple step that would make Django play more nicely with a SIEM
[One of a series of bugs from a discussion I had with @mallyvai about improving the security of Django's admin - see https://gist.github.com/mallyvai/bcb0bb827d6d53212879dff23cf15d03 for the full list.]

Hi Tim,
Definitely think it's a good idea to add to the docs.
My original thinking was that it would be a more sensible default to log this as a security exception and use the django.security loggers (i'm not 100% sure about how that's wired up), since CSRF protections are meant to be explicit security measure. It seems to be logged as a generic logger.warning right now.

Sergio Campos (seocam) and I were just discussing this same issue at the PyCon sprint (in the context of looking at the broader context in #26688). I'm inclined to agree with mallyvai that this isn't just a doc bug -- we should be logging CSRF failures to django.security by default. Updating the ticket title accordingly -- please let me know if you don't agree, or think this should be discussed on the mailing list.

Are you concerned at all about backwards-compatibility in the case of some custom logging configuration?
comment:8 by , 8 years ago
I guess I'm not too concerned about back-compat, because it seems it would only be an issue in a case where someone has configured logging to watch django.request but ignore django.security, which seems like a pretty strange choice. But I also don't feel strongly. I'd be inclined to merge the doc fix that Hwesta has already submitted (https://github.com/django/django/pull/6694/files) but as a Refs, and leave this open for further discussion of the actual logger change.

The
CsrfViewMiddlewaredoes have logging for rejected requests. Is this insufficient? I couldn't find this mentioned in the documentation so that could be added, at least.
