Question

For this assignment, evaluate the above network diagram for a basic small marketing firm in San Francisco, CA. You have been asked to writeup a basic risk assessment for this company. In the first part, brainstorm and list every risk you can imagine (realistic for this company) include virtual, physical and stupid- in your listing. Provide a brief one-to-two sentence overview for each risk you list. In the second section, pick the top risk and create a Quantitative RA (last week) for a single loss expectancy. Each event will have its own price tag and amount of downtime. The values for each device is listed as P for physical cost and V for the estimated value of the data on each device. Each day the network is down results in a loss of $86,000.00.

Explanation / Answer

Hi

The Below are the risks at various level.

Physical: Hardware level :If you can see there is only switch/router connecting to all the users and servers.

In case of failure the LAN/WAN connectivity will be impacted. The servers should be on dual NIC each connected to different switch this will eliminate the risk of link faliure between switch and server(LAN connectivity).

Link level: It can be seen all the devices are connected on single link if the link gets disconnected due to some incident the connecting server/devices will be isolated.

Internet Link : Single internet link will cause the Internet connectivity risk.in case link gets down , branch/office will be isolated.

Virtual Risk: I can see all the devices in single VLAN. Broadcast domain would be same packets would flooded in the entire network . Server/network performance will be impacted heavily.

This is a reasonably short answer.

Thanks!!
