What is the difference between wired and wireless networks...

What is the difference between wired and wireless networks from a security perspective What are the differences between LAN and WAN networks? A minimum of 2 ways of how networks might be vulnerable to attack Measures you would recommend to implement a secure a network for use in an organization -- would there be differences between what is appropriate for an organization with only one or two sites and one that has hundreds?

00:01 All right, so first for security differences between wired and wireless networks.

00:05 We first have physical security.

00:16 So wireless networks are generally more secure in terms of unauthorized access because an attacker must have a physical connection to the network to access it.

00:29 And this would then limit the potential for remote attacks.

00:32 For wireless networks are more susceptible to unauthorized access because attackers can attempt to connect from a distance.

00:41 And then we have eavesdropping.

00:54 So eavesdropping requires physical access to the cable infrastructure to intercept data, making it more challenging for attackers, for wired networks, and for wireless networks.

01:05 They broadcast data through the air, making it easier for attackers to intercept the data if the network is not properly secured with strong encryption.

01:15 Then for the second part of the question here, the difference is between lan and wan.

01:24 So for lan, that would be local area networks and then wan is wide area.

01:41 So a lan or local area network covers a small geographic area, like an office building or home providing high speed connections.

01:51 And for the wan, that would span a large geographic area such as cities, states, or even countries, typically consisting of multiple lans connected together.

02:02 So for control, the lan is usually under the control of a single organization, where the wan often involves multiple organizations and service providers...
