Departments and Agencies, via their Permanent Secretaries and Chief Executives, must manage their security risks within the parameters set out in the framework, as endorsed by the Official Committee on Security (SO). All HMG employees (including contractors) have a collective responsibility to ensure that government assets (information, personnel and physical) are protected in a proportionate manner from terrorist attack, and other illegal or malicious activity.
