DeepMind released a new paper on "AI Control" — a framework for securing AI Agent systems using cybersecurity thinking. The core idea: even if an AI Agent is aligned, it can still cause harm (intentionally or unintentionally), and we need a separate "control" layer that monitors and constrains the Agent's actions.

The "internal threat" framing: traditional AI safety has focused on "alignment" — making the AI want to do the right thing. But alignment is not enough: even a perfectly aligned Agent can cause harm due to misunderstandings, distribution shift, or adversarial inputs. The "AI Control" framework treats AI Agents as "internal threats" — like a malicious employee who has legitimate access but might misuse it.

The cybersecurity playbook: AI Control borrows the "defense in depth" concept from cybersecurity. Multiple layers of defense — (1) input validation (check the Agent's inputs for prompt injection); (2) action monitoring (check the Agent's actions for safety violations); (3) output filtering (check the Agent's outputs for sensitive data); (4) audit logging (record every action for forensic analysis); (5) rate limiting (prevent the Agent from performing too many actions too quickly).

The "alignment + control" division: DeepMind argues that alignment and control are complementary — alignment makes the AI "want" to do the right thing, control makes it "able" to do the right thing. The two together provide defense in depth. The paper includes a set of "control protocols" — best practices for deploying AI Agents with control measures in place.

The bigger takeaway: "AI Control" is a significant new direction in AI safety. The traditional "alignment-only" approach is being augmented with "control" measures borrowed from cybersecurity. For the industry, this means enterprises deploying AI Agents will need to invest in "Agent control" infrastructure — similar to how they invest in cybersecurity infrastructure today. The next round of investment in Agent infrastructure will include "Agent firewalls," "Agent audit logs," and "Agent action allow-listing."
