The best option is to provide sanitized devices with remote connections to a Virtual Desktop Infrastructure (VDI). This ensures that no sensitive intellectual property is stored locally on the laptops carried across borders. Even if the devices are inspected, seized, or tampered with, attackers cannot access corporate data since all sensitive files remain within secure, centralized infrastructure.
Option A (Measured Boot) reports firmware tampering but does not prevent data theft if the device is compromised. Option C (self-encrypting drives) protect data at rest but can be bypassed if customs agents demand login credentials. Option D (tamper-evident stickers) provide only physical inspection indicators and are ineffective against sophisticated data theft attempts.
CAS-005 emphasizes secure remote access strategies and temporary "clean laptops" for high-risk travel scenarios. Sanitized laptops with VDI access minimize exposure while maintaining productivity, making this the strongest mitigation.
