If not feasible, provide adequate protection, such as floor cable protectors or utility poles. For underground cables, use armoured conduits or markers to protect against accidental damage. b) Cable Separation: Keep power cables separate from communications cables to prevent interference. c) Additional Controls for Sensitive or Critical Systems: 1. Install armoured conduits, lockable rooms or boxes, and alarms at inspection and termination points. 2. Use electromagnetic shielding to protect cables. 3. Conduct regular technical sweeps and physical inspections to detect any unauthorised devices attached to the cables. 4. Control access to patch panels and cable rooms using mechanical keys or PINs. 5. Consider using fibre-optic cables for added security. d) Cable Labelling: Label cables at both ends with clear source and destination details to facilitate easy identification and inspection. ### Additional Notes Seek specialist advice for managing risks related to cabling incidents or malfunctions. Be aware that power and telecommunications cabling might be shared with other organisations in co-located premises. This guide provides straightforward recommendations to ensure the security and integrity of power, data, and information service cabling. - [Getting Started](https://knowledge.adoptech.co.uk/getting-started?hsLang=en#main-content) - [Getting Started](https://knowledge.adoptech.co.uk/getting-started?hsLang=en#getting-started) - [Accounts & Billing](https://knowledge.adoptech.co.uk/getting-started?hsLang=en#accounts-billing) - [FAQ's on Adoptech](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#main-content) - [Frameworks](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#frameworks) - [Policies & Documents](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#policies-documents) - [Risk Management](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#risk-management) - [Supplier Management](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#supplier-management) - [Audit Preparation](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#audit-preparation) - [Trust Centre](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#trust-centre) - [User Management](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#user-management) - [Frameworks & Certifications](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#main-content) - [ISO 27001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-27001) - [ISO 42001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-42001) - [Cyber Essentials](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#cyber-essentials) - [CAF](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#caf) - [PCI-DSS](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#pci-dss) - [SOC2](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#soc2) - [Data Privacy (GDPR)](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#data-privacy-gdpr) - [DORA](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#dora) - [ISO 9001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-9001) - [ISO 22301](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-22301) - [ISO 14001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-14001) - [NIST 800-53](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#nist-800-53) - [NIST-CSF](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#nist-csf) - [NIS2](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#nis2) - [ISO 20000-1](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-20000-1) - [HIPAA](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#hipaa) - [Integrations](https://knowledge.adoptech.co.uk/integrations?hsLang=en#main-content) - [Cloud Infrastructure](https://knowledge.adoptech.co.uk/integrations?hsLang=en#cloud-infrastructure) - [Identity & Access](https://knowledge.adoptech.co.uk/integrations?hsLang=en#identity-access) - [DevOps & Code](https://knowledge.adoptech.co.uk/integrations?hsLang=en#devops-code) - [Project Management](https://knowledge.adoptech.co.uk/integrations?hsLang=en#project-management) - [HR & People Systems](https://knowledge.adoptech.co.uk/integrations?hsLang=en#hr-people-systems) - [Security & Devices](https://knowledge.adoptech.co.uk/integrations?hsLang=en#security-devices) - [Communication & Collaboration](https://knowledge.adoptech.co.uk/integrations?hsLang=en#communication-collaboration) - [Legal & Regulations](https://knowledge.adoptech.co.uk/legal-regulations?hsLang=en) - [Security Guidance](https://knowledge.adoptech.co.uk/security-guidance?hsLang=en) - [Troubleshooting](https://knowledge.adoptech.co.uk/troubleshooting?hsLang=en) [![Chill listening crop-3](https://knowledge.adoptech.co.uk/hs-fs/hubfs/adoptech-logo-1.png?width=209&height=54&name=adoptech-logo-1.png "Chill listening crop-3")](https://adoptech.co.uk/) Copyright © 2026, Adoptech Ltd.
