Compliance Node Overview
MITRE ATT&CK T0804 (Block Reporting Message) is an ATT&CK for ICS Inhibit Response Function technique. Adversaries may block or prevent a reporting message from reaching its intended target. In control systems, reporting messages contain telemetry data (e.g., I/O values) pertaining to the current state of equipment and the industrial process. By blocking these reporting messages, an adversary can potentially hide their actions from an operator. Blocking reporting messages in control systems that manage physical processes may contribute to system impact, causing inhibition of a response function. Affected asset classes: None. MITRE-documented mitigations include M0814 Static Network Configuration, M0810 Out-of-Band Communications Channel, M0807 Network Allowlists. Operational-technology controls map to NIST SP 800-82 Rev 3 and the IEC/ISA 62443 series.
