7.12 Cabling Security

Cables carrying power, data or supporting information services should be protected from interception, interference, or damage.

Cabling security is a term used to refer to the measures taken to secure the cables and other physical components of a computer network. This can include measures such as physically securing the cables to prevent unauthorised access, using encrypted cables to prevent data interception, and regularly inspecting and maintaining the cables to ensure they are in good working order. The goal of cabling security is to prevent unauthorised access to the network and protect the data that is transmitted through the cables.

There are several guidelines to consider when implementing cabling security in an information security system. Some of these guidelines include:

• Physical security: This involves securing the cables and other physical components of the network to prevent unauthorized access. This can include measures such as using cable locks, enclosing cables in protective conduits, and physically securing access points to the network.
• Encryption: Using encrypted cables can help prevent data interception and protect the confidentiality of the information transmitted through the network.
• Regular inspections and maintenance: Regularly inspecting and maintaining the cables can help ensure they are in good working order and can help identify potential security vulnerabilities.
• Access controls: Implementing access controls can help prevent unauthorized access to the network and protect the data transmitted through the cables. This can include measures such as requiring authentication for access to the network and using access control lists to restrict access to specific users or groups.
• Fire protection: Implementing fire protection measures can help prevent damage to the cables and other physical components of the network. This can include measures such as using fireproofing materials and installing fire suppression systems.
• Disaster recovery: Having a disaster recovery plan in place can help ensure that the network remains operational even in the event of a disaster. This can include measures such as regularly backing up data and having redundant systems in place to provide backup connectivity in case of an outage.
