There are several physical threats in both router and switch
when it comes to implementation of that device. It can be categorized as four
categories. This includes hardware threats, environmental threats, electrical
threats and maintenance threats.
In hardware threat, the hardware can be damaged due to act
of mischief or deliberate act. To mitigate this threat, the organization shall
think of ways to minimize any damage. The organization can consider limiting
the number of point of entry to the server room to minimize any damage done.
This includes allowing only authorized users to gain entry to the server room.
Besides that, logging of every entry is also important to personal
accountability. Security camera is also important because it serve as deterrent
purpose (Temasek Polytechnic, n.d.) .
In environmental threat, overheated router and switch will
damage the equipment. Hence there is a need to “control” these environmental
factors. These include air-conditioning, humidity control and environmental
alarm system as well as recording to inform the helpdesk when the server has a
high temperature (Temasek Polytechnic, n.d.) .
In electrical threat, abrupt power outage might crash the router
and switch. Therefore, by installing Uninterruptible Power Supply (UPS) will
help to provide electrical supply ranging from 5 to 15 minutes
(“Uninterruptible power,” 2012). In this short period of time, the technician
will be able to shut down the server in a rightful manner (Temasek
Polytechnic, n.d.) .
In maintenance-related threat, we can limit any damage done
due to maintenance-related work such as poor cabling (Sud &
Edelman, 2003) .
As a result, there is a need to provide
label for important cables. Besides that, providing additional cables for every
router and switch will helps to ensure high availability of the network.

Hi KimChye,
ReplyDeleteafter reading your post, i've understood more about the threats which can affect our router & switch. Not only is your post comprehensive, you've also provided diagrams to illustrate the threats even further.
This post has taught me that there are actually many different types of possible threats such as environmental & maintenance threats which can damage our devices, not only just hardware threats. For instance, electrical threat such as the abrupt power shortage which can suddenly cause our router to stop functioning & turned off abruptly can also affect it. After thinking through, i agree with this statement. Not only so, i realised that my router was also a victim of such threats before!
Thanks for stimulating my thinking & great job! :)
