Checklist of ISO/IEC 27001-A.11.2.3 Cabling security

Introduction:

In the digital era, data is the backbone of organizations. Therefore, it is essential to protect the physical infrastructure that supports the data and IT systems. 

This is where cabling security comes into play. 

Cabling security is the protection of the physical infrastructure that supports data and IT systems. 

This includes cables, junction boxes, air conditioner chillers, microwave dishes, air inlets, and patch panels. 

In this article, we will discuss the checklist for cabling security to ensure the safety and security of your organization’s IT systems.

Sample Checklist:

  • Physical Protection: Check if the external cables, junction boxes, air conditioner chillers, microwave dishes, air inlets, and other components are physically protected against accidental damage or deliberate interference. This will ensure the uninterrupted functioning of your organization’s IT systems.
  • Segregation of Power Cables and Communication Cables: Verify if the power cables are segregated from communication cables to prevent interference. This will prevent data loss or corruption and ensure the smooth functioning of your organization’s IT systems.
  • Access Control: Check if access to patch panels and cable rooms is controlled. This will prevent unauthorized access to sensitive data and IT systems. Also, ensure that the cabling is concealed and protected against eavesdropping by attaching rogue devices or physical damage.
  • Compliance with Regulations and Standards: Verify that cabling installations are done in accordance with building codes and other applicable regulations, standards, and policies. This will ensure the safety and security of your organization’s IT systems.
