Businesses have abruptly reassessed their ability to deal with security threats in the wake of Sept. 11, according to a survey of 100 business executives by Kroll, a New York City-based risk consulting company. Before the terrorist attacks, information protection and employee integrity were the top security priorities. Since then, concern with emergency planning, business resumption planning and physical security has increased dramatically. Emergency planning is now viewed as "important" by 86 percent of the respondents, compared with 34 percent before Sept. 11. Physical security is considered "important" by 89 percent, up from 40 percent.
