**TL;DR** - GPU security fundamentally broken on current hardware; enterprise security layers consolidating; AI spear-phishing attacks hit new sophistication level.
1. Enable IOMMU on systems where GPU DMA attacks are a concern - it is a BIOS setting most people never touch
2. If buying security tools, prefer platform solutions over point solutions - consolidation trend accelerating
3. AI spear-phishing personalization is the new normal - assume attackers know everything you have publicly posted
**Example Prompt:**
Design a GPU security architecture that protects against DMA attacks while maintaining performance for ML workloads.
| Pros | Cons |
|---|---|
| IOMMU mitigation effective | Not all hardware supports it with GPU passthrough |
| Platform consolidation cost-effective | Best-of-breed sometimes beats platform |
|---|---|
| AI spear-phishing now commodity | Defense against personalized attacks extremely hard |
