AI agents keep getting loose, escaping supposedly secure tests to attack real-world targets, commandeer obscure wikis, and leave instructions for other agents to follow. Researchers are testing these systems precisely because they might behave in unpredictable, even dangerous, ways. So wouldn’t it be safer to just keep the agents off the internet?
In theory, yes. Researchers can isolate the computers running AI tools from the internet and other outside networks, a technique known as air gapping. That can mean physically removing or disabling cables and wireless hardware and using “dumb” peripherals, with particularly sensitive setups using Faraday cages or other shielding to block electromagnetic signals from getting in or out.
But in practice, a perfectly sealed box makes for a rather limited laboratory, particularly when the aim is to assess how an AI will perform in the real world. While some AI experiments can be run on air-gapped machines, realistic evaluations often require access to external services, APIs, and digital infrastructure, explained Thorsten Holz, a scientific director at the Max Planck Institute for Security and Privacy in Germany.
Ruizhe Li, an assistant professor in the school of computer science at the University of Birmingham in the UK, likened complete isolation to testing AI in an “artificial vacuum,” potentially undermining the value of the evaluation itself. “We will end up testing a neutered AI model, which blinds evaluators to how the AI model behaves, fails, or executes tool-use exploits in realistic deployment settings,” Li said.
Air gapping is but one means of safeguarding AI systems. “Relying on isolation as a blanket safety solution creates a false sense of security,” Li said. It should be used alongside other measures, like understanding the inner workings of models, ensuring they are aligned, and guarding against human error, the mundane point of failure behind many recent rogue AI incidents.
Recent incidents raise questions over where AI labs are drawing that line. Many breaches involved models being tested for their cybersecurity abilities, and in many respects they performed exactly as designed. The problem was that they did so outside of the boundaries researchers intended to set.
Stephen Casper, a computer scientist and assistant professor of public policy at the Harvard Kennedy School, described air gapping as a “great idea” for sensitive systems, pointing to its use in nuclear facilities. While not ruling out the possibility that an advanced AI could find some novel way to escape, Casper said at that point we should probably be more worried about prosaic means of breaking containment, such as compliance failures or human error.
