An increase in laptop thefts—plus several new state laws on data-theft disclosure— are causing employers to establish tougher security policies for employees’ laptops, PDAs and other tech devices. A recent survey says 10 percent of laptops are stolen within the first 12 months of purchase, and nine of 10 are never recovered. In the past three years, several states have passed laws requiring employers to notify customers and employees (and sometimes, the police) whenever personally identifiable data (Social Security numbers, etc.) have been breached. Security experts suggest that travelers never leave laptops unattended and carry them in backpacks or tote bags, rather than in telltale laptop bags.
