lan and wan

 

A LAN, abbreviated from Local Area Network is a network that covers a small geographical area such as homes, offices, and groups of buildings.


Whereas a WAN, abbreviated from Wide Area Network is a network that covers larger geographical areas that can span the globe. An example of a widely used WAN is the Internet, which is a collection of tens of thousands of networks that connects tens of billions of devices.

Local Area Networks predominantly use Ethernet technology, which is a group of networking technologies that dictate how data is transmitted over the physical media, with the most common media being CAT# cabling. Local Area Networks can use both Layer 1 and Layer 2 devices; Layer 1 devices include HUB’s and repeaters and the Layer 2 devices that can be used are switches and bridge devices. While LAN’s use Layer 1 and Layer 2 devices, WAN’s operate using Layer 3 devices such as multi-layer switches and routers. LAN’s are typically cheaper than WAN’s to both implement and maintain as the equipment required for Local Area Networks is less expensive, however, you can be more cost-efficient when setting up a WAN if you were to use VPNs.

A LAN that is implemented well can bring multiple benefits to an organization such as high fault tolerance, scalability, security as well as fast and reliable speeds. Local Area Networks have higher bandwidth than Wide Area Networks, as well as being able to transmit data at much faster speeds. This is mainly due to the distance the data needs to travel as well as restrictions in place, such as an ISP’s speed restrictions over leased lines. Another important factor that determines how fast data can be transmitted over the network is dependent on hardware and cable quality, in addition to the data transferability of these also having an effect. Local Area Networks are more secure than Wide Area Networks due to how WANs transmit the data and how far the data would need to travel. A WAN is usually not owned and maintained by a single organization/entity like LAN’s are, therefore you have much less control over the network.

network firewall

  The network firewall is the first line of defense for traffic that passes in and out of a network. The firewall examines traffic to ensure it meets the security requirements set by the organization, and unauthorized access attempts are blocked. Firewall protection has come a long way in recent years. In addition to monitoring internet traffic, the latest network firewall security products incorporate a wide range of additional features. “The latest firewalls can neutralize an attacker’s ability to use stolen credentials for lateral movement and network compromise,” said Navneet Singh, product marketing director at Palo Alto Networks. “This is done by enforcing multi-factor authentication at the network layer.” The intention behind network firewalls is that they filter internet transmissions so that only traffic that belongs is allowed into an organization. Decisions are based on pre-set rules or policies. Like many areas of technology, firewalls have evolved gre...
