- Some scripts used wrong SSH module/namespace scoping on events.
- Fix outdated notice documentation related to SSH password guessing.
- Add a unit test for SSH pasword guessing notice.
* origin/topic/johanna/cert-validation:
and still use the hash for notice suppression.
add knob to revert to old validation behavior
Update certificate validation script - new version will cache valid intermediate chains that it encounters on the wire and use those to try to validate chains that might be missing intermediate certificates.
BIT-1332 #merged
intermediate chains that it encounters on the wire and use those to try
to validate chains that might be missing intermediate certificates.
This vastly improves the number of certificates that Bro can validate.
The only drawback is that now validation behavior is not entirely
predictable anymore - the certificate of a server can fail to validate
when Bro just started up (due to the intermediate missing), and succeed
later, when the intermediate can be found in the cache.
Has been tested on big-ish clusters and should not introduce any
performance problems.
ssl connections with old versions as well as unsafe cipher suites.
Also make the notice suppression handling of other ssl policy files
a tad more robust.
Now the right signer certificate for the reply is looked up (and no longer assumed that it is the first one) and a few compares are fixed. Plus - there are more test cases that partially send certificates in the ocsp message and partially do not - and it seems to work fine in all cases.
Addresses BIT-1212
This also fixes the heartbleed detector to work for encrypted attacks in this
branch again. It stopped working, because the SSL analyzer now successfully detects
established connections, and the scripts usually disable analyzing after that.
(The heartbeat branch should not have been affected)
The scope of dns.log is now only standard queries (OPCODE == 0). Other
kinds of queries (e.g. inverse query) were not handled correctly and
could interfere with the state tracking of the default DNS scripts.
Changes:
- Changing semantics of the new_event() meta event: it's raised
only for events that have a handler defined. There are too many
checks in Bro that prevent events wo/ handler from being even
prepared to raise to do that differently.
- Adding test case.
* topic/robin/event-dumper:
New script misc/dump-events.bro, along with core support, that dumps events Bro is raising in an easily readable form.
Prettyfing Describe() for record types.
- 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.
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?
- 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.
