Final answer:
Key concerns when using a government-issued laptop in public include the risk of insecure public Wi-Fi connections without a VPN, leaving the device unattended, exposure of sensitive information during meetings with foreign officials, and personal web browsing.
Step-by-step explanation:
When using a government-issued laptop in public, one should have multiple concerns due to potential risks to both the device and the sensitive information it may contain. One major concern is connecting to public Wi-Fi without a VPN (Virtual Private Network), which exposes the laptop to potential security breaches such as man-in-the-middle attacks or eavesdropping. Another concern is leaving it unattended in your hotel room, where it could be stolen or tampered with. Additionally, bringing it to a meeting with a foreign official could risk exposure of sensitive information to foreign entities. Lastly, using it to browse personal websites may invite unnecessary risks like malware infections or reveal personal browsing habits to employers through network monitoring.
