Digital defenses mean very little if someone walks up to an unlocked laptop signed into a corporate AI assistant, or if a key business process silently depends on an AI service no one has planned to operate without. Physical and operational security remains the quiet foundation on which AI security rests, and a handful of well-chosen practices significantly reduce risk for small and mid-sized businesses.
- Protect Workstations:
- Enforce Screen Locks: Configure short auto-lock timers on every device that connects to AI tools, including those used by executives whose AI conversations may be especially sensitive.
- Encrypt All Devices: Enable full-disk encryption on laptops, tablets, and phones that access AI tools, so loss or theft does not become a data breach.
- Control Physical Access:
- Apply Least Privilege: Limit physical access to areas containing AI infrastructure, executive workstations, or sensitive data to those who truly require it for their role.
- Manage Visitors: Require visitors to sign in, wear badges, and be escorted, and ensure they never have casual access to workstations signed into corporate AI accounts.
- Secure Hardware and Media:
- Locking Storage: Store laptops, drives, and other devices holding AI-related data securely when not in use, particularly outside business hours.
- Certified Disposal: Wipe or destroy drives that may hold AI prompts, outputs, or training data using certified processes, and retain certificates of destruction for audits.
- Plan for AI Outages:
- Identify Dependencies: Document every business process that depends on AI availability, especially customer-facing workflows where downtime would be immediately visible.
- Define Manual Fallbacks: Establish and periodically test manual or alternative procedures for critical processes so the business can continue operating during AI vendor outages.
- Ensure Environmental Resilience:
- Power and Cooling: For self-hosted AI workloads, maintain appropriate power redundancy and climate control, and test backup systems before they are actually needed.
- Connectivity Backups: Plan for internet outages — including secondary connections where the business depends heavily on cloud-based AI — to avoid sudden, complete loss of capability.
- Address Insider Risk:
- Cross-Check Activity: Correlate physical access logs with AI usage so unusual combinations, such as off-hours AI activity from an empty office, are noticed and investigated.
- Separation of Duties: Ensure no single person controls both the AI environment and the logs that record how it is used, reducing the risk of undetected misuse.
