Wall Street Security Gets New Line of Defense
Days of Easy Access to the Underground Ending

(CBS) NEW YORK Monday was just another day on Wall Street. Another billion and a half shares traded. Every investor order delivered electronically, all through an extensive technical circuit below ground.

In most parts of the city, gaining access to electric, cable or fiber optics takes about a minute through manholes.

"It's just too easy for terrorists, vandals to gain access to the underground," said Mike Manoussos of Manhole Barrier Security Systems.

But now on Wall Street, to get below you first have to get through a new form of barbed wire. Below 183 manhole covers in the financial district are steel security devices.

And unless you have the coded key ... "You would need some kind of special saw and about an hour drilling to try to get through it," Manoussos said. "This is really the beginning of an infrastructure of security."

The beginning of a plan to create a ring of steel around the financial district, like in London where there are points of entry and exit and battalions of closed-circuit TV cameras.

"Bin Laden himself has said he wants to attack our economic system," CBS 2 security expert Bob Strang said. "What better way than to attack the New York Stock Exchange and to attack where we transfer billions of dollars a day."
