Cyberattackers pose many threats to a wide range of targets. Russia, for example, was accused of hacking Democratic Party computers throughout the year, interfering with the U.S. presidential election. Then there was the unknown attacker who, on a single October day, used thousands of internet-connected devices, such as digital video recorders and cameras compromised by Mirai malware, to take down several high-profile websites, including Twitter.
From 2005 to 2015, federal agencies reported a 1,300 percent jump in cybersecurity incidents. Clearly, we need better ways of addressing this broad category of threats. Some of us in the cybersecurity field are asking whether cyber deterrence might help.
