Information Security Policy

October 2020

Information is essential to delivering services to citizens and businesses. Information security refers to the defence of information or information systems from unauthorised or unintended access, destruction, disruption or tampering.  It is important that the Council acts appropriately with the information we obtain and hold.  Confidentiality, integrity and availability of information must be proportional and appropriate to maintain services, comply with the law and provide trust to our customers and partners.  

Application of policy 

Everyone who accesses information the organisation holds must be aware of these policy statements and their responsibilities in relation to information security.

This policy should be read in conjunction with the Acceptable Use policy and Data Protection policy.  This policy will be reviewed annually.
