Re: blocked instead of alert
From: Balla István <balla.bmf () gmail com>

thanks for the answers so far. three questions: 1. how to look for a rule
according to sig/den id (in this case 18/129) in an event?
2. how to determine if this event has been triggered by preproc rule or
decoder rule or detection rule?
3. where I can find the pcap file you are looking for to see more details?

     yes, it is unified2. the last piece of (Event) is the *blocked:1.*

right... i see that... that is what u2spewfoo is outputting...


While you can  help Waldo, here i think you bring a bit of confusion
to the thread.

sorry if that is happening... it is not my intention... i only try to
bring out
the necessary details to solve the problem...

The initial question from Balla is, why event 1 is considered as
blocked while the other is not considered as blocked.

right... the log file that u2spewfoo is processing will tell us why
u2spewfoo is
saying it is a block... that's what i'm saying... we have to get to the
root to
find the cause...

[trim]
i'm asking what a blocked entry looks like in the /raw/ unified2 log
file...
that is the key to figuring out and understanding why it is being shown
by
u2spewfoo as a block...

Blocked is a unified2 structure field and its part of every unified2
event type,
its set by the engine, thus u2spewfoo does not makeup "block", its
only displaying it.

my thought was that something may have been misinterpreted by u2spewfoo in
this
case... it is possible that snort has a bug and wrote the output
incorrectly...
so far there's not enough info to determine that and i don't think a pcap
will
help without the full configuration as well... even then, that may not help
solved the problem...
