Common Threats to Router & Switch Physical and Mitigation

HELLO THIRD TOPIC!!

There are 4 categories of Common Physical Threats to Router and Switch Installations.

They are :

1) Hardware Threats
2) Environmental Threats
3) Electrical Threats
4) Maintenance Threats

Hardware Threats

Any threats that are associated with physical damages to the routers and switches are all classified as hardware threats. Through controlled access to the facilities, one can mitigate these hardware threats. One can also provide security by ensuring that there is no access to the facility via the ceilings, AC ducts, windows or walls. Mitigation of hardware threats can also be done through the installation of security cameras and the logging of entry attempts.

Environmental Threats


Any threats that are associated with climatic conditions are environmental threats. Adequate ventilation in the facility and the maintenance of temperature and humidity levels are needed to mitigate such threats. In addition, one must ensure that the temperature and humidity levels are maintained in accordance to the specifications defined in the equipment documentation. Once all these parameters are in place, the ability to remotely manage and monitor the temperature and humidity controls is a necessity. Ensuring that the facility is free from electrostatic discharge (ESD) and magnetic interference is also another way to mitigate environmental threats.

Electrical Threats

Some examples of electrical threats can be spikes, inadequate power supply, noise and power loss. An uninterruptible power supply (UPS) is needed for all your devices that you heavily rely on. A UPS provides protection against irregularities in your power distribution system. Ensure that there are redundant power supplies within your network devices for those who can support them, and also have spares always at your facility. This measure reduces the downtime of your network, should it occur.

Maintenance Threats


Some things like poor cabling, faulty labelling or electronic devices without adequate ESD deterents, they are all classified as maintenance threats. Do make sure that the cables are labelled properly and that a proper labeling convention is followed. Having properly labelled cables helps in tracing cables in the facility and helps in troubleshooting as well. Ensure that the cables have smooth bends when going around corners, for a more smoother flow of data.
