> Currently, the SIP Security Event Framework exists in a separate file from {{chan_sip}} (yay!) and provides function calls that raise security events when something goes suspiciously. While it may seem like the best approach is to refactor this out as a separate module, there's a few reasons to not do so:
> # Most of the SIP security framework exists as a very thin wrapper over the more generic Asterisk Security Event Framework. As such, there's limited benefit in making this code itself a separate resource module
> # The non-generic portion of the code is specific to how {{chan_sip}} performs authentication, which is less than ideal
> Instead, we should provide a new resource module that does two things:
> # During authentication, inspects requests/responses and raises the appropriate events
> # Provides facilities that other modules can use to raise security events
> At a minimum, the following should be covered:
> * An invalid endpoint was requested
> * An ACL was violated
> * An invalid password was provided
> * An authentication occurred successfully
> * A session limit violation occurred
> * A challenge response failed
> * A challenge response was sent
