1. Rename yara_matches to yara_events.
2. Add support for Config::getParser().
- This returns a ConfigPluginRef, which is the ConfigParser for the
given key.
- Being able to get the parser is useful because the
YARAConfigParserPlugin uses it to store the compiled rules as an
attribute.
3. Finish rename and use ConfigParserPlugin.
- Finish the table rename to yara_events.
- Use the new ConfigParserPlugin interface to parse the YARA
configuration. The file_paths and signatures are stored in the
ConfigParserPlugin named "yara" under the key "yara". The rules are
compiled and stored as a private attribute of the same
ConfigParserPlugin object.
Here is an example config using this new structure:
{
// Description of the YARA feature.
"yara": {
"signatures": {
// Each key is an arbitrary group name to give the signatures listed
"sig_group_1": [ "/Users/wxs/foo.sig", "/Users/wxs//bar.sig" ],
"sig_group_2": [ "/Users/wxs/baz.sig" ]
},
"file_paths": {
// Each key is a key from file_paths
// The value is a list of signature groups to run when an event fires
// These will be watched for and scanned when the event framework
// fire off an event to yara_events table
"system_binaries": [ "sig_group_1" ],
"tmp": [ "sig_group_1", "sig_group_2" ]
}
},
// Paths to watch for filesystem events
"file_paths": {
"system_binaries": [ "/usr/bin/%", "/usr/sbin/%" ],
"tmp": [ "/Users/wxs/tmp/%%" ]
}
}
- Currently the signature file must be an absolute path.
3. Move common YARA code to yara_utils.
- In preparation for the yara table (different from yara_events) I'm
moving the common YARA code into a separate place which is shared
between the two tables.
4. Add yara table.
- This allows you to do things like:
```sql
select * from yara where path="/bin/ls" and sigfile="/tmp/foo.sig";
select * from yara where path="/bin/ls" and sig_group="sig_group_1";
```
- The latter will use the signature grouping from the config.
5. Check for keys not existing.
