Authentication is very important for networks. In wireless networks, there are different authentication types. One of these wireless authentication types is Pre-Shared Key (PSK). In this lesson, we will learn the details of Pre-Shared Key (PSK) and we will learn Cisco PSK Configuration. Let’s firstly start with what is PSK?
Pre-Shared Key (PSK) is an authentication type which is used in wireless networks. With PSK Authentication, a key string is used to authenticate the clients in the wireless network. So, on each wireless client, PSK should be configured with the same Pre-Shared Key in the network.
Pre-Shared Key (PSK) uses WPA (Wi-Fi Protected Access). There are three versions of WPA. These WPA Types are given below:
We have talked about the details of WPA (Wi-Fi Protected Access) versions in another lesson.

WPA (Wi-Fi Protected Access) is basically a network security protocol used in wireless networks. The aim of this network security protocol is to secure the wireless networks.
WPA (Wi-Fi Protected Access) supports two different authentication methods. These WPA authentication methods are given below:
To use Pre-Shared Key (PSK) in a wireless network, there are different benefits. These are given below:
Beside these benefits, there are also some disadvantages of using PSK. These disadvantages are given below:
First of all, all the devices which uses this authentication has the same Pre-Shared Key. This is a security risk for wireless networks.
It is difficult to identify any device in the network with this same Pre-Shared Key.
Using same key in the network needs more key change not to be open malicious threats.
