WiFi, the latter of which has increasingly become a target for hackers hoping to mess up our chi. To predict what would happen as result of an assault, researchers at North Carolina State University created two models -- one based on a continuous jam of service, and one on an intermittent disruption that would cut off service during specific times. They then measured "order gain," which compares the probability of an attacker having network access to the probability of a legitimate user having access. Basically, the more control a hacker has, the more regular users that will lose service and be shut out -- making it harder to regain control. Researchers hope the new method will help identify the most vulnerable networks, opening the doors to create effective countermeasures to keep our WiFi safe -- something that Starbucks customers will surely be thankful for.
