Setting up a security key for a wireless network

Personal information and files on your wireless network can sometimes be seen by people who pick up your network signal. This can lead to identity theft and other malicious acts. A network security key or passphrase can help protect your wireless network from this type of unauthorized access..

Wi-Fi Protected Access (WPA and WPA2)

WPA and WPA2 require users to provide a security key to connect. Once the key has been validated, all data sent between the computer or device and the access point is encrypted. There are two types of WPA authentication: WPA and WPA2. If possible, use WPA2 because it is the most secure. Almost all new wireless adapters support WPA and WPA2, but some older ones don’t. In WPA-Personal and WPA2-Personal, each user is given the same passphrase. This is the recommended mode for home networks. WPA-Enterprise and WPA2-Enterprise are designed to be used with an 802.1x authentication server that distributes different keys to each user. This mode is primarily used in work networks.

Therefore the best mode for security is using Wi-Fi Protected Access (WPA and WPA2).

Network Topology

The physical topology of a network refers to the configuration of cables, computers, and other peripherals. Physical topology should not be confused with logical topology which is the method used to pass information between workstations.

Main Types of Network Topologies

In networking, the term “topology” refers to the layout of connected devices on a network. This article introduces the standard topologies of computer networking.

One can think of a topology as a network’s virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network. For example, the computers on a home LAN may be arranged in a circle in a family room,

Network topologies are categorized into the following basic types:

The topology used above is Mesh Topology, it involves the concept of routes. Unlike the other topologies, messages sent on a mesh network can take any of several possible paths from source to destination.
