America's leaders are calling on state and local authorities to help guard against the heightened terror threat.
Tightening security has been an ongoing endeavor at the Port of Gulfport since September 11, 2001.
New high-masted lights, security cameras and fencing have been put up for protection.
A new command center will be built just north of the West Terminal Gate.
The new facility will have state-of-the art equipment.
Local law enforcement agencies say any place is a target, and everyone can help out when it comes to homeland security.
"Some people say I don't know if I want to call that in our not, but I encourage you. Our President has challenged each one of us to take of each other, so I encourage everybody. If you see something suspicious, call it in," said Major Wayne Payne of the Harrison County Sheriff's Department.
