13. Infrastructure 13.1. Cable Management Fundamentals Objective Recommended Control 01: Recommended Control 02: Recommended Control 03: Cable management systems are implemented to allow easy integration of systems across government and minimize the opportunity for tampering or unauthorized change Agencies should use fiber optic cable for backbone infrastructures and installations Agencies should use fiber optic cabling Agencies should not use fiber optic cable incorporating conductive metal strengtheners or sheaths except where essential for cable integrity The design of a backbone requires consideration of a number of criteria including the capacity of the cable to carry the predicted volume of data at acceptable speeds. An element of “future proofing” is also required as re‐cabling to manage capacity issues can be costly. Fiber optic cable provides a convenient means of securing and “future proofing” backbones. Fiber optic cable is considered more secure than copper cables and provides electrical isolation of signals. Fiber will also provide higher bandwidth and speed to allow a degree of future‐proofing in network design. 13.2. Cable Management for Non‐Shared Government Facilities Objective Recommended Control 01: Cable management systems in non‐shared government facilities are implemented in a secure and easily inspectable and maintainable way Cabling shouldbe inspectable at a minimum of five‐meter intervals Regular inspections of cable installations are necessary to detect any unauthorized or malicious tampering or cable degradation in non‐shared government facilities. 13.3. Objective Cable Management for Shared Government Facilities Cable management systems in shared government facilities are 56
