Verifying IOMMU and SMMU DMA protection requires reading kernel configuration, firmware settings, and device trees. This Skill analyzes hardware-software interfaces to confirm these features are enabled, preventing unauthorized Direct Memory Access across your system's components.

Hardware-software trust model coherence ensures software security assumptions align with actual hardware capabilities. Analyzing kernel configuration, firmware settings, and device trees verifies that hardware security features like MTE and PAC are properly enabled and trusted by the operating system.

Auditing boot chain security and memory protection involves systematically reviewing firmware settings, kernel configurations, and hardware documentation. This Skill checks control flow integrity features and verifies the boot chain to ensure robust hardware-level security is correctly configured.

Yes, checking kernel security features like MTE and PAC requires analyzing both kernel configurations and firmware settings. This Skill verifies hardware feature enablement by reading these sources to ensure security mechanisms are correctly activated across the hardware-software interface.

Reviewing hardware security feature enablement is best done by analyzing kernel configurations, firmware settings, device trees, and hardware documentation. This Skill systematically verifies IOMMU/SMMU configurations and boot chain integrity to provide a comprehensive security audit.

Software may assume hardware security features are active when firmware or kernel configurations disable them. This Skill identifies trust model incoherence by cross-referencing software assumptions with actual hardware capabilities found in device trees and firmware settings.
