For several weeks, it has been difficult to open a newspaper or watch a Sunday talk show without hearing about the advent of “cyber war.” The media has been filled with an avalanche of cyber threat-related stories: the hacking of leading newspapers, evidence of Chinese government involvement in intellectual property theft, and now, further distributed denial of service attacks against U.S. banks. All these events present real and serious national security challenges. But cyber-espionage, cyber-crime and the malicious disruption of critical infrastructure are not the same as war, and the distinction is important.
The idea that America is in the middle of a “cyber war” isn't just lazy and wrong. It's dangerous. The war analogy implies the requirement for military response to cyber intrusions. America genuinely needs effective civilian government cyber defense organizations with strong relationships with the private sector and the active engagement of an informed general public. Creating and even promoting the fear of “cyber war” makes that more difficult. Here’s why:
First, while the U.S fights its wars using the highly-trained professional within the U.S. Armed Forces, defending against cyber threats does not necessary require military expertise or prowess. True, most private individuals and corporations lack the knowledge and training needed to fight off attacks from elite Chinese, Iranian and Russian cyber “warriors.” As a result, there is and will continue to be a pressing need for highly qualified information security experts to help defend the larger U.S. cyber landscape. Nonetheless, there are relatively simple ways to make it more difficult for the bad guys without escalating to a “war” standing. In 2011, the Australian Defence Signals Directorate (their equivalent of the U.S. National Security Agency) showed that by taking just four key measures--“whitelisting” (i.e., allowing only authorized software to run on a computer or network), very rapid patching of applications and of operating system vulnerabilities, and restricting the number of people with administrator access to a system--85 percent of targeted intrusions can be prevented. These might appear more like prophylactic public health measures than warfare--and that’s the point. The United States does not need to declare “war” and call up the military to fend off cyber threats.
