- 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.
- Simplified the communication API and made it easier to change
to encrypted connections by not having separate variables to
define encrypted and unencrypted ports.
- Now, to enable listening without configuring nodes just
load the frameworks/communication/listen script.
- If encrypted listening is desired set the following:
redef Communication::listen_encrypted=T;
- Accompanying test updates.
- 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.
- I removed the byte loss estimate since everything indicated that
it could frequently be inaccurate.
- It has it's own logging stream now. Notices are only used
when too much loss has been detected (CaptureLoss::Too_Much_Loss)
- The gap_report event isn't used anymore. I'm scheduling events
to get the same effect by using the get_gap_summary BiF to
collect the gap summary on demand.
- scan.bro and hot.conn.bro will be returning soon.
- The rest are going to return as updated protocol analysis
scripts and new/updated frameworks later.
Updated README and collected coverage-related tests in a common dir.
There are still coverage failures resulting from either the following
scripts not being @load'd in the default bro mode:
base/frameworks/time-machine/notice.bro
base/protocols/http/partial-content.bro
base/protocols/rpc/main.bro
Or the following result in errors when @load'd:
policy/protocols/conn/scan.bro
policy/hot.conn.bro
If these are all scripts-in-progress, can we move them all to live
outside the main scripts/ directory until they're ready?
- protocols/ssl/expiring-certs uses time based information from
certificates to determine if they will expire soon, have already
expired, or haven't yet become valid.
- protocols/ssl/extract-certs-pem is a script for taking certs off
the line and converting them to PEM certificates with the openssl
command line tool then dumping them to a file.
- Removed an notice definition from the base SSL scripts.
- Moved a logging stream ID into the export section for known-services
and bumped priority for creating the stream.
- Adding configuration knobs for the SQL injection attack detection
script and renaming the HTTP::SQL_Injection_Attack notice to
HTTP::SQL_Injection_Attack_Against
- Bumped priority when creating Known::CERTS_LOG.
- Log path's are generated in the scripting land
now. The default Log stream ID to path string
mapping works like this:
- Notice::LOG -> "notice"
- Notice::POLICY_LOG -> "notice_policy"
- TestModule::LOG -> "test_module"
- Logging streams updated across all of the shipped
scripts to be more user friendly. Instead of
the logging stream ID HTTP::HTTP, we now have
HTTP::LOG, etc.
- The priorities on some bro_init handlers have
been adjusted to make the process of applying
filters or disabling streams easier for users.
- If the misc/pf-ring-load-balancing script is loaded, the correct
environment variables will be set to enable automatic flow based
load balancing used pf_ring if Bro is built against the pf_ring
libpcap wrapper. Loading the script on non-Linux OSs or when Bro
isn't linked against the correct libpcap has no known side effects
since the script just sets environment variables.
- Added a BiF named setenv for setting environment variables.
- Missing GeoIP databases now generate warnings/errors that go through
the reporter framework instead of hitting GeoIP's internal use of
stderr
- lookup_location now just queries for country code if the city database
was not loaded, which gets rid of invalid database type errors.
- lookup_location now leaves missing fields uninitialized in the
returned geo_location record value. Updated existing scripts to
check for initialized fields in geo_location records before use.
- Fixed support for GeoIP's IPv6 API and databases
