#206: Knowing the ruleset id generating alerts
-------------------------+--------------------------------------------------
Reporter: toady | Owner: yoann
Type: enhancement | Status: closed
Priority: normal | Milestone: Prelude-LML 0.9.9
Component: prelude-lml | Version: devel
Severity: normal | Resolution: fixed

Comment (by yoann):
Certain rules using variable classification.text, we wouldn't be able to
use the ID as classification.ident since IDMEF state:
{{{
The "ident" attribute value MUST be unique for each particular
combination of data identifying an object, not for each object.
Objects may have more than one "ident" value associated with
them. For example, an identification of a host by name would
have one value, while an identification of that host by address
would have another value, and an identification of that host by
both name and address would have still another value.
Furthermore, different analyzers may produce different values for
the same information.
}}}
Although this specific issue could be fixed, there is also another issue
with alert generated from multiple rules, through context. Since we want
to record all matched rules ID and revision, using AdditionalData should
be the way to go.
This has been implemented in [9391].
