**TL;DR** - GPU security fundamentally broken on current hardware; enterprise security layers consolidating; AI spear-phishing attacks hit new sophistication level.
The 10-Second Pitch
GPU driver security years behind CPU security - GPU memory can be accessed via DMA attacks without kernel involvement
Enterprise security vendors consolidating - point solutions being absorbed by platform vendors
AI-powered spear-phishing now personalizes attacks using public data, LinkedIn profiles, and previous breach dumps
Setup in 3 Steps
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.
Verdict
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
GPU security is most underappreciated attack surface in modern enterprise infrastructure.
