South African Security firm Thinkst is hoping to give new life to an old idea—the honeypot—in a bid to help organizations detect security breaches and intruders in their private networks. Thinkst's Canary is a simple network appliance and corresponding online monitoring service that makes it easy to set up juicy-looking targets on the corporate LAN that will sound the alarm if any attempt is made to access them. One of the consistent features of large hacks, such as the late 2013 Target breach, is that attackers have been able to move around their victims' networks to find systems with interesting or valuable data without being detected.
