Make sure lookup_hostname_txt isn't checking lookup_hostname's cache for answers.
A couple of lookup_hostname_txt fixes.
Reverting the earlier function-join during merging.
- There are still some broken events in the modbus analyzer because
I don't have traffic to test with (coil and record related events primarily).
- There are a few example scripts in policy/protocols/modbus
- New script measures a couple of aspects of SMTP traffic.
- Existing metrics scripts had a small amount of work done
to make them work with changes to metrics framework.
* origin/topic/bernhard/software:
change software framework interface again. At the moment everything should worl.
start reworking interface of software framework. working apart from detect-webapps.bro, which direcly manipulates a no longer available interface...
after talking to seth - change host_a field in record back to host.
forgotten policy files.
Software framework stores ports for server software.
* origin/fastpath:
Fix missing action in notice policy for looking up GeoIP data.
Better persistent state config warning messages (fixes#433).
A few updates for SQL injection detection.
Fixed some DPD signatures for IRC. Fixes ticket #311.
Removing Off_Port_Protocol_Found notice.
SSH::Interesting_Hostname_Login cleanup. Fixes#664.
Teach Broxygen to more generally reference attribute values by name.
Fixed a really dumb bug that was causing the malware hash registry script to break.
Fix Broxygen confusing scoped id at start of line as function parameter.
Remove remnant of libmagic optionality
- The biggest change is the change in notice names from
HTTP::SQL_Injection_Attack_Against to
HTTP::SQL_Injection_Victim
- A few new SQL injection attacks in the tests that we need to
support at some point.
- Added a field named $last_alert to the SSL log. This doesn't even
indicate the direction the alert was sent, but we need to start somewhere.
- The x509_certificate function has an is_orig field now instead of
is_server and it's position in the argument list has moved.
- A bit of reorganization and cleanup in the core analyzer.
- New script extracted from weird.bro to implement the
connection related "weird" data into an optionally
loaded script.
- Adjusted the default notice tuning to stop ignoring
the connection related weirds since they aren't loaded
by default anymore.
- Certificate validation volume has been greatly cut down by
caching results.
- Cert hashing is now done in one place instead of being repeated
everywhere a cert hash was needed.
- Some small cleanups for notice suppression that should greatly reduce
duplicate notice volume about invalid certificates.
- With the software-browser-plugins script you can watch for Omniture
advertising servers to grab the list of installed plugins.
- I reorganized the plugin detection a bit too to abstract it better.
- Removed the WEB_ prefix from all of the Software::Type HTTP enums.
They were essentially redundant due to the full name already being
HTTP::SERVER (for example).
- I was wildly misunderstanding the semantics of the
connection_state_remove event. That's fixed now in
my brain and in the script.
- If a service isn't detected, logging is delayed by
2 minutes to try and allow for another connection
to happen that actually does the protocol correctly
and detectably.
