Consequences
Confidentiality, Integrity, Access Control: Modify Memory, Read Memory, Bypass Protection Mechanism
Potential Mitigations
Phase: Architecture and Design
Description:
The fabric firewall should apply the same protections as the original region to the mirrored regions.
Phase: Implementation
