Software House, a part of Tyco Security Products, has added critical security functionality to the latest version of its C•CURE 9000 security and event management system. C•CURE 9000 v1.93 offers more control over who goes where and when, thus creating a more secure environment for employees and visitors, and enhanced safeguarding of confidential information. New security features include: occupancy restrictions (limits the number of people in a given area to protect highly classified information and adhere to occupancy guidelines); N Man Rule (requires more than one person to present a card in order for access to be granted); and clearance filters (adjust clearance levels based on changes in threat level or other emergency situations).
