Introduction Information and information systems are important corporate assets and it is essential to take all the necessary steps to ensure that they are at all times protected, available and accurate to support the operation and continued success of the Trust. The Trust acknowledges that we must demonstrate to third parties our expertise in security technology and implementing it. To achieve this it is recognised that we must protect our own assets as well as the environment. The aim of the Trust s Security Policy, Security Standards and Work Instruction Manual is to maintain the confidentiality, integrity and availability of information stored, processed and communicated by and within the Trust. These standards, procedures and policies are used as part of the information security management system (ISMS) within the Trust. This document sets out the procedures in place to ensure that all documents forming the ISMS are subject to a formal process of issue, amendment and withdrawal. The procedures are designed to ensure that: Documents are approved prior to issue by designated individuals; Documents are issued to only those authorised to receive them; Obsolete documents are withdrawn and a copy of the superseded document is retained within an archive library; Responsibilities for document control are assigned; Access to electronic media containing the ISMS is controlled. This procedure applies to all documents which comprise the overall Information Security Management System (ISMS).
