Evan,
Question A:
A WAN (wide area network) is a network that covers a much larger area than a typical small business that would utilize a LAN. A WAN utilizes multiple LANS in order to create a WAN link. A benefit of a WAN is that it can allow for network locations over large geographic distances. For example, a business that has multiple locations across the country would benefit by creating a WAN from the necessary LANS, routers, and network setups to create this link. With, WAN will have a couple drawbacks. For one, a WAN is unlikely to perform as fast as a LAN. Along with this, a WAN is more expensive to setup.

Question B:
My article was about how the LabCorp lab processing conglomerate recently detected suspicious activity on their networks. This caused several systems shuts downs which caused delays and outages. Though the issue has since been resolved, it calls into mind the importance of network security within the medical field. The article referenced a LA hospital in 2016 that paid thousands of dollars in ransom money due to a ransomware attack. It’s important to consider the incredibly important data that is contained within these systems. Along with this, many hospitals require strong network security to effectively care for patients. This makes network security incredibly paramount within these organizations.

Respond to the following:
Matthew,
Question A:
A WAN or Wide Area Network is a network connection of computers over a large area such as a city, state or country. A LAN or Local Area Network is network connection of computers that are generally small and used mostly in homes, business, or a school. A collection of LAN’s will make up a WAN. The internet is another example of a Wide Area Network. LAN’s are generally faster and are more secure, but WANs allow access to more information as they cover a much larger area.

Question B:
I wanted to find an article that closely talked about our main topic this week. This article shows how a small company, CB Alliance, that has offices globally tackled the problem of slow connection speeds for its employees. When the MPLS network design didn’t meet the need of the company, they turned to the experts at Cato Cloud. They were able to take advantage of Cato Cloud’s software-defined WAN (SD-WAN) on the Cato Network. This change for CB Alliance increased productivity and allowed some employees to work from home. Increasing the speed by an average of 60 times what they had previously, will improve morale for employee’s.
