Unit commanders are on the front lines in the war to protect the Navy’s information systems. They must take the lead in developing strong information security problems.
There is ample evidence that hackers, foreign nations, and terrorist organizations are testing and probing Navy information systems for vulnerabilities. The number and complexity of cyber attacks against the Department of Defense (DoD) has more than doubled each year since 1998.
The greatest source of attacks on DoD systems still appears to be hackers, but according to recent congressional testimony by former FBI officials, "we are picking up increased signs that terrorist organizations are looking at the use of this technology" to attack the United States.
