The Business Roundtable (BRT), an association of CEOs of 150 U.S. companies, is calling on corporate boards of directors to make security a priority and to bring it under board review. The Washington, D.C.-based organization is adding the security component to its Principles of Corporate Governance, a set of best practices it has developed to guide corporate governance practices. "Providing for the security of employees, facilities, customers and communities is a fundamental function of business in this post 9/11 era," says C. Michael Armstrong, chairman of The Business Roundtable as well as Comcast Corp. The Business Roundtable is asking boards of directors to designate management responsibility for business resiliency and to periodically review management's plans as part of their oversight function. Resiliency can include risk assessment; management, business continuity, physical and cyber security; and emergency communications, the BRT says.
