| C2 agents shall report queue status within the heartbeat message at regular intervals | Agents must report queue status to the C2 server at regular intervals |
| C2 agents shall execute acknowledge commands sent via a heartbeat response | Agents must execute and acknowledge commands from the C2 server |
| C2 agents shall apply requested changes and inform the C2 server of success or failure | Agents must apply and acknowledge updates from the C2 server, responding with a success or failure |

C2 Messages
Heartbeats
Primary communications are carried over a C2 heartbeat. The heartbeat contains operational information about the C2 agent and can occur a configurable frequency. The heartbeat provides status information to the C2 server. The response from the heartbeat contains requested operations from the C2 server. These operations are then acknowledged if/when they are completed. This means that the heartbeat is the only operation initiated by the C2 agent and the C2 server responds directly to these heartbeats.
