Hackers attacked the computer network at the Naval War College in Newport, taking down the school's network for more than two weeks, including some e-mail services and the college's Web site.
The Navy Cyber Defense Operations Command in Norfolk, Virginia, detected the intrusion around November 16 and took the system offline, spokesman Lt. Cmdr. Doug Gabos said. He said the unclassified network was used by students.
Investigators were trying to determine the extent of the intrusion, Gabos said. They planned to upgrade firewalls and make other unspecified improvements.
"Once that is complete, the network will be restored," Gabos said.
Gabos would not comment on who is suspected of attacking the network.
