Only current as an electronic version on Parknet Page 3 of 7 Remote access is connecting to the corporate computer system by any computer that is not connected to the Corporate Network using the Authority’s ICT
The provision of Remote Access must be controlled in order to protect Authority systems. The controls determine who can access Authority systems, how they can access and what can be accessed.
Authority systems can be accessed remotely by various people: • Members and Staff whilst out of the office.
• Staff to provide support for systems
• Suppliers to provide Remote Administration on systems • Third Parties requiring approved access to Authority systems
3 Governance factors
The controls on remote connections to the corporate network arise from the rules predefined in the Codes of Connections which other Local Authority’s are required to comply with in order to use secure networks. Whilst Dartmoor National Park
Authority does not currently connect to any separate secure networks, the controls that would be required are considered to be examples of best practice.
Examples of secure networks include, but are not limited to: • Government Connect
• Payment Card Industry Data Security Standard (PCI DSS)
