If America declares a cyberwar, what does that even look like? And who are our soldiers?

Earlier this week, US Central Command's Twitter and YouTube accounts were hacked ... allegedly by pro-Islamic State activists. Meanwhile authorities are still trying to determine if North Korea was the culprit behind the breach at Sony.

Both high profile hacks prompted President Obama to speak yesterday about the need for greater cyber security measures.

To that end, he's proposing several laws to better crack down on hackers.

However, the idea of launching a cyber war or cyber counteroffensive isn't something that most of us are that familiar with.

When an American site or installation is attacked by guns or bombs, for example, we know what happens: the military is deployed and Congress might even vote to declare war.

But Shane Harris, fellow at the New America Foundation and author of "@War: The Rise of the Military-Internet Complex," explains the logistics and articles of cyberwar.
