When inserting, existance of the given subnet is checked using exact
matching instead of longest prefix matching. Before, inserting a subnet
would have updated the subnet item, which is the longest prefix of the
inserted subnet, if present.
The intel-framework now supports the new indicator type Intel::SUBNET.
As subnets are matched against seen addresses, the field matched was
introduced to indicate which indicator types caused the hit. A testcase
for subents was added and the old ones have been updated accordingly.
By addind debug output to Intel::insert() the testcase reveals that
updating an intel item will cause its metadata to be inserted again,
without the old being deleted.
- Intel importing format has changed (refer to docs).
- All string matching is now case insensitive.
- SMTP intel script has been updated to extract email
addresses correctly.
- Small fix sneaking into the smtp base script to actually
extract individual email addresses in the To: field
correctly.
- Intel data distribution on clusters is now pushed in whole
by the manager when a worker connects. Additions after that point
are managed by the normal single-item distribution mechanism already
built into the intelligence framework.
- The manager maintains the complete "minimal" data store that the
workers use to do their matching so that full "minimal" data
distribution is very easy.
- Tests are cleaned up and work.
- All 5 intelligence tests pass.
- Some initial memory optimizations done.
- More work needs done to reduce duplicate data in memory.
- Input framework integration.
- Define files to read in the "Bro intelligence format" in Intel::read_files.
- Cluster transparency.
- DNS Zones are a fully supported data type.
- Queries for Intel::DOMAIN values will automatically check in DNS_ZONE intelligence.
