🚨 Breaking changes 🔨

Tracee policies apiVersion and kind were renamed.

eg:

apiVersion: tracee.aquasec.com/v1beta1
kind: Policy
metadata:
  name: dig
  annotations:
    description: traces dns events from the dig binary
spec:
  scope: 
    - binary=/usr/bin/dig
  rules:
    - event: net_packet_dns_request        
    - event: net_packet_dns_response

🚀 What's new? 🚀

💡 New GRPC API (Experimental) ☎️

Tracee now has a fully functional beta GRPC API. The following operations are supported with more coming in the future:

• Consume events using GRPC stream
• Enable/Disable events
• Diagnostics & Logging
• Performance Counters

Note that events by the GRPC API follow a new event structure which isn't compatible with the older event structure. In future versions of Tracee this new structure will replace the older one for all other interactions.

🗃️ Process Tree 🌲

Tracee now maintains live representation of the system processes tree. This information is exposed to signatures through the datasource mechanism (a mechanism that allows golang signatures to access data collected by tracee events).

• An example on how this feature can be used, by a signature event, can be found HERE.
