Command And Control

MITRE ATT&CK Description:

Adversaries may communicate using application layer protocols to avoid detection/network filtering by blending in with existing traffic. Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and server.

Adversaries may utilize many different protocols, including those used for web browsing, transferring files, electronic mail, or DNS. For connections that occur internally within an enclave (such as those between a proxy or pivot node and other nodes), commonly used protocols are SMB, SSH, or RDP.

Possible playbook uses:

The playbook can be used independently to handle and remediate the specific technique.
The playbook can be used as a part of the “Courses of Action - Defense Evasion” playbook to remediate techniques based on the kill chain phase.
The playbook can be used as a part of the “MITRE ATT&CK - Courses of Action” playbook, which can be triggered by different sources and accepts the technique MITRE ATT&CK ID as an input.
