We are building an internal threat catalog entry for MITRE ATT&CK ICS T0815. Engineers suggested listing 5 general IT firewall mitigations. What exact count and set of official ATT&CK mitigation IDs address Denial of View?
| Checked | Without skill | With skill |
|---|---|---|
| Specifies that exactly 3 mitigation controls apply to T0815. | Passed | Passed |
| Includes M0810 Out-of-Band Communications Channel in the mitigation set. | Missed | Passed |

Adversaries may cause a denial of view in attempt to disrupt and prevent operator oversight on the status of an ICS environment. This may manifest itself as a temporary communication failure between a device and its control source, where the interface recovers and becomes available once the interference ceases.
An adversary may attempt to deny operator visibility by preventing them from receiving status and reporting messages. Denying this view may temporarily block and prevent operators from noticing a change in state or anomalous behavior. The environment's data and processes may still be operational, but functioning in an unintended or adversarial manner.
Platforms: ICS
Determine if the target ICS/SCADA environment is susceptible to Denial of View by examining operational technology systems and network architecture.
Review whether mitigations for T0815 are in place. If defenses are absent or misconfigured, this technique may be exploitable in the ICS environment.
Provide operators with redundant, out-of-band communication to support monitoring and control of the operational processes, especially when recovering from a network outage . Out-of-band communication should utilize diverse systems and technologies to minimize common failure modes and vulnerabilities within the communications infrastructure. For example, wireless networks (e.g., 3G, 4G) can be used to provide diverse and redundant delivery of data.
Take and store data backups from end user systems and critical servers. Ensure backup and storage systems are hardened and kept separate from the corporate network to prevent compromise. Maintain and exercise incident response plans , including the management of gold-copy back-up images and configurations for key systems to enable quick recovery and response from adversarial activities that impact control, view, or availability.
