The author examines the validity of the claims that an electo-magnetic pulse bomb presents an immediate threat to U.S. infrastructure, arguing that "advocates for EMP preparation could end up being their own worst enemy.'"

A war game, sponsored by a nonprofit group and attended by former top-ranking national security official exposed gaps in U.S. preparedness for cyberwarfare.

The US will take on a broader range of military responsibilities, including defending space and cyberspace, in spite of growing pressure on budgets, according to the latest Quadrennial Defense Rev­iew.

The United States faces an evolving list of potential adversaries in the 21st century that not only continue to seek weapons of mass destruction, but are honing the skills necessary to wage battle in cyberspace as well as outer space, a panel of national security experts said Jan. 20.

Recent events demonstrate how quickly the nation’s escalating cyberbattles have outpaced the rush to find a deterrent, something equivalent to the cold-war-era strategy of threatening nuclear retaliation.

Militants in Iraq have used $26 off-the-shelf software to intercept live video feeds from U.S. Predator drones, potentially providing them with information they need to evade or monitor U.S. military operations. The drone intercepts mark the emergence of a shadow cyber war within the U.S.-led conflicts overseas. They also point to a potentially serious vulnerability in Washington's growing network of unmanned drones, which have become the American weapon of choice in both Afghanistan and Pakistan.

The United States has begun talks with Russia and a United Nations arms control committee about strengthening Internet security and limiting military use of cyberspace. Officials familiar with the talks said the Obama administration realized that more nations were developing cyberweapons and that a new approach was needed to blunt an international arms race.

In 2003, the Pentagon and American intelligence agencies made plans for a cyberattack to freeze billions of dollars in the bank accounts of Saddam Hussein and cripple his government’s financial system but cancelled it out of concern that the attack would create widespread financial havoc. Fears of such collateral damage are at the heart of the debate as the Obama administration and its Pentagon leadership struggle to develop rules and tactics for carrying out attacks in cyberspace.

A new study suggests that under the right circumstances, terrorists could break into computer systems and launch an attack on a nuclear state – triggering a catastrophic chain of events that would have a global impact.

The South Korean military will have an electromagnetic pulse (EMP) bomb in five years that is capable of crippling an enemy's command-and-control, communications and defense radar systems.
