Cybersecurity has vexed the government ever since ENIAC — the first-ever electronic computer, which was used by the Army in the 1940s — first coughed into life and got a bug in one of its relays.

In recent years, the cyber threat has become a real national security concern and the Defense Department has responded in kind, hammering out a doctrine declaring cyberspace to be a fifth domain, alongside the traditional land, sea, air and space.

The Pentagon announced the creation of a U.S. Cyber Command in 2009 and the command reached full operational capacity in October 2010. It’s matched by similar command functions in each of the armed services.

For a progress report on how the military is combating the cyber threat and a look at the near term future, officials from the Army, Navy and Air Force cyber commands joined the Federal Drive with Tom Temin and Amy Morris for a special Federal News Radio panel discussion.
